We used cross-sectional data from 226 patients with monkeypox virus to investigate the association between anatomic exposure site and lesion development. Penile, anorectal, and oral exposures predicted lesion presence at correlating anatomic sites. Exposure site also predicted the first lesion site of the penis and anus. [ABSTRACT FROM AUTHOR]

Background: Premature ejaculation (PE) is a common sexual problem, resulting in adverse effects on the quality of life, of both the patient and the partner. The idea of muscular contraction inhibition during the ejection phase of ejaculation by Botulinum toxin-A injection may delay ejaculation. Aim of study: This study was performed to assess the efficacy and safety of Botulinum toxin-A injection in PE treatment. Material and methods: This study included 45 married male patients diagnosed with primary PE. All included patients were injected with 75 units of Dysport equal efficacy of 25 units of Botulinum toxin-A (Botox) into three sites: the root of the penis (Group 1), glans penis (Group 2), and each side of the ischiocavernosus muscle (Group 3). All patients were subjected to an assessment of intravaginal ejaculation latency time (IELT) using a stopwatch and answering the Premature Ejaculation Diagnostic Tool (PEDT) Questionnaire before and after treatment. Results: There was a statistically significant improvement in IELT after treatment in all groups. The most significant improvement was shown in Group 3 (average 108% increase), followed by Group 1 (74%) and Group 2 (40%), respectively. There was a positive correlation between age and the improvement in improved IELT. There was a statistically significant improvement in PEDTq scores in Group 1 and Group 3. Conclusion: Botulinum toxin-A injection into the root of the penis and ischiocavernosus muscle could be recommended in the treatment of premature ejaculation. [ABSTRACT FROM AUTHOR]

The well-characterized edible and medicinal bamboo mushroom is Phallus indusiatus, a Chinese bamboo mushroom with long white indusium (skirt). To date, scientists have found more than five species of bamboo mushrooms in Thailand, containing bamboo mushrooms with long white, short white, and several colored skirts. Still, most of them are unidentified species and lack metabolic profile data. Hence, this study aims to evaluate the species of the long white-skirt Chinese bamboo mushroom-like (CH-isolate) and short white-skirt (TH-isolate) bamboo mushrooms isolated from a local farm in northern Thailand. External morphology and molecular identification were used to identify the species. Nutritional and metabolic studies were conducted to determine the nutrients and metabolites from both isolates. Our morphological and evolutionary phylogenetic analyses suggested that CH- and TH-isolates were different species. Interestingly, the CH-isolate, which has a similar morphology to P. indusiatus, clearly demonstrated the difference in species. In addition, the nutritional and metabolomic analysis revealed that CH- and TH-isolate contain different nutritional constituents and metabolic profiles. Our study reports the two new species of bamboo mushrooms that were suspected to be found in Thailand and their metabolic profiles that could be beneficially used in further studies. However, definitive confirmation of the novel species will be made in the future. [ABSTRACT FROM AUTHOR]

Introduction: Triphallia, a rare congenital anomaly describing the presence of three distinct penile shafts, has been reported only once in the literature. This case report, based on an extensive literature review, describes the serendipitous discovery during cadaveric dissection of the second reported human case of triphallia, distinctly morphologically different from the previous case. Case presentation: Despite the normal appearance of external genitalia on examination, the dissection of a 78-year-old white male revealed a remarkable anatomical variation: two small supernumerary penises stacked in a sagittal orientation posteroinferiorly to the primary penis. Each penile shaft displayed its own corpora cavernosa and glans penis. The primary penis and largest and most superficial of the supernumerary penises shared a single urethra, which coursed through the secondary penis prior to its passage through the primary penis. A urethra-like structure was absent from the smallest supernumerary penis. Conclusion: This case report provides a comprehensive description of the anatomical features of triphallia in a cadaver, shedding light on the morphology, embryology, and clinical implications of this anomaly. Without dissection, this anatomical variation would have remained undiscovered, suggesting the prevalence of polyphallia may be greater than expected. The single tortuous urethra present in this case, as well as the supernumerary and blind ending urethras present in many cases of penile duplication, may pose significant risk of infection, sexual dysfunction, subfertility, and traumatic catheterization. Significance: These findings underscore the importance of meticulous anatomical dissections and may act as a resource for anatomists and those studying genitourinary anomalies. Although we can only speculate as to which functional implications this patient may have experienced, understanding such anatomical variations contributes to both knowledge of human anatomy and clinical management should the condition be encountered in living individuals.

Background: In recent years, there has been growing interest in the use of hyaluronic acid (HA) for the treatment of premature ejaculation (PE). The efficacy of this treatment is quite controversial. Aim: This study intended to evaluate the efficacy and safety of glans penis augmentation with HA gel for PE. Methods: This systematic review includes randomized controlled trials (RCTs), primary clinical trials, prospective and retrospective studies, case series, and case reports. Searches in Embase, PubMed, Cochrane, Web of Knowledge, and ClinicalTrials.gov were performed blindly by 2 reviewers. Outcomes: Intravaginal ejaculation latency time (IELT), questionnaires about PE, glans circumference (millimeters), and adverse events. Results: Thirteen studies were included in the evaluation: 4 RCTs, 8 prospective observational studies, and 1 restrospective study. The number of patients who received HA gel on the glans penis was 706. According to the results of 2 placebo-controlled RCTs, HA gel treatment significantly improved IELT at the end of the first month (mean difference [MD], 65.44 seconds). In the first month after the HA gel injection procedure, IELT increased vs before the procedure (MD, 176.18 [95% CI, 146.89-205.48]; P <.001, I2 = 83%). When the IELT values ​​were compared at 6 months after HA gel application, IELT improved vs before the procedure (MD, 143.93 [95% CI, 124.78-163.09]; P <.001, I2 = 82). The glans circumference expanded by approximately 1.5 cm after the procedure (MD, 14.82 mm [95% CI, 12.75-16.90]; P <.001, I2 = 65%). When the side effect profile of other studies was examined, side effects were observed in 91 patients after HA gel injection applied to 598 patients (15.22%). Among these side effects, the most common were pain (n = 46, 7.69%), bulla/nodule formation (n = 25, 4.18%), and ecchymosis (n = 20, 3.34%). Conclusion: While HA shows promise as a therapeutic option for PE, ongoing research is essential to elucidate its clinical utility, mechanisms of action, and comparative efficacy.

Phalloplasty can be performed using both free and pedicled flaps. Complications include flap-related healing compromise and urethral issues, including stricture and fistula. Phalloplasty has high patient satisfaction and has demonstrated improvement in quality of life. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate the expression of core molecular clock genes/proteins in penile cavernous tissue from healthy male subjects and to determine whether their expression has circadian variation. Materials and Methods: Corpus cavernosum biopsy samples were obtained from 10 healthy males with penile deviation or fracture who underwent surgical intervention during the day and night. The daytime group (n=5) underwent corpus cavernosum tissue sampling during zeitgeber time (ZT) 8–12, while the nighttime group (n=5) underwent sampling during ZT 20–24. The expression and localization of BMAL1, CLOCK, PER1, PER2, PER3, CRY1, and CRY2 proteins were analyzed using immunohistochemistry and quantified using H-score analysis. RT-qPCR analysis was performed to assess the expression of core molecular clock genes in the corpus cavernosum tissue of 5 additional daytime patients. Results: The expression of core molecular clock proteins was detected in vascular endothelial cells (VECs) and smooth muscle cells (SMCs) in corpus cavernosum during daytime and nighttime. BMAL1 exhibited the most significant nuclear expression during daytime in both cell types, whereas its expression decreased significantly at night. In VECs, a significant decrease in the nuclear expression of CRY1 was observed at night. In SMCs, a significant decrease in the cytoplasmic expression of PER3 was observed at night. The expression patterns of the core molecular clock genes were ascertained through a RT-qPCR analysis. Conclusions: Our research provides compelling evidence that core molecular clock genes are distinctly expressed in penile tissue in humans. Furthermore, we observed the expression of molecular clock proteins within the VECs and SMCs of the corpus cavernosum, with BMAL1 being the most prominently expressed. The discovery of core molecular clock genes in penile tissue, as well as proteins within the SMCs and VECs of the corpus cavernosum, introduces the potential significance of the molecular clock mechanism in the physiology of penile erection.

Penile skin zipper entrapment is an emergent medical condition in which the penile skin, scrotal skin, or foreskin gets caught within the teeth of a zipper or the slider itself. This can lead to complications such as urethral involvement, skin loss, or tissue necrosis. We propose a novel technique to aid in the release of entrapped skin utilizing wire cutters directed at the inferior portion of the zipper pull. To describe a novel technique to free entrapped penile skin and compare its performance to the well-established median bar technique in a simulated setting. A randomized cross-over design was used to compare techniques on successful release, time to release and tissue injury using an animal model of raw chicken skin entrapped in a zipper. Statistical significance was assessed at p < 0.05. Twenty-two participants were included. There was no statistically significant difference between the novel technique and the median bar technique regarding successful release (100% vs 95.5%, respectively), median time to release (29.1 vs 26.4 seconds, respectively), or frequency of tissue injury (22.7% vs 27.3%). Performance using our novel technique for removal of penile skin from a zipper is similar to the median bar release technique regarding. Our novel technique may be a valid treatment option for the release of entrapped penile skin in a zipper mechanism in the emergency department setting. [ABSTRACT FROM AUTHOR]

Throughout world history, moles and birthmarks have occupied a special place as omens. Little is known of the cultural beliefs concerning the determinants of coercive control. In this ethnographic study of coercive control in Cambodia, the focus is on popular beliefs that moles are omens portending that men shall control women. Lachrymal moles (under the eye) signify women weeping as a result of misery. Penile moles portend men attracting, controlling, even abusing women. They have implications for reinterpreting an "insider" view of hegemonic masculinity and for culturally responsive interventions against gender-based violence. [ABSTRACT FROM AUTHOR]

Simple Summary: Sugar gliders are exotic animals that have become pets in recent years. As a result, these small marsupials are increasingly coming to the veterinary practices. Marsupials are a group of mammals characterized by their peculiar way of reproduction. This translates into the distinct anatomy of their genital apparatus, both male and female. There are not many references concerning the anatomy of this particular species. The male reproductive system of the Petaurus breviceps follows the general pattern in marsupials, but each species has its own peculiarities that the veterinary clinician should know. It includes two testes, epididymis, and deferent ducts, as well as two types of accessory glands: the prostate and the bulbourethral glands, in addition to the male urethra and the penis, which is bifid at its end. The purpose of this study was to describe the male genital gross anatomy of the sugar gliders (supplemented with some microscopic observations), to provide detailed information to veterinary clinicians to facilitate accurate diagnosis and surgery. The present study provides a detailed macroscopic examination (with some microscopic insights) of the genital apparatus of seven adult and intact male sugar gliders, as well as one castrated individual. The scrotum is pendulous and attached to the ventral abdominal wall, situated in the caudal part of the abdomen and cranial to the cloacal opening. The testes are oval shaped with their long axes oriented vertically. The epididymides are attached along the caudomedial border of their respective testes. The head and tail of the epididymides are in close proximity to the poles of the testes but are not directly attached. The deferent ducts are positioned laterally to their ipsilateral ureter as they run near the dorsal surface of the urinary bladder. The ampulla of the deferent duct is absent. The penis is located post-scrotally, lacks insertion into the bony pelvis, and has a bifid distal end. The crura of the penis originate within the ischiocavernosus muscles, and there are two bulbs of the penis. When flaccid, the entire penis is concealed in the perineal region and externalizes through an orifice situated in the ventral part of the cloaca, traversing its floor towards the cloacal opening. The urethral external orifice is positioned at the point where the bifurcation of the free part of the penis begins. The prostate gland resides in the pelvic cavity and consists of two parts: a macroscopically visible body surrounding the urethra and a microscopically identifiable portion embedded within the walls of the duct. Sugar gliders possess two pairs of bulbous bulbourethral glands, located dorsally and laterally to the rectum, but lack vesicular glands. [ABSTRACT FROM AUTHOR]

Simple Summary: This study investigates the microbiome of bulls infected with Tritrichomonas foetus (T. foetus), a protozoan causing bovine tritrichomoniasis. It aims to describe the preputial, penile, and seminal microbiomes of chronically infected bulls and evaluate different sampling methods. Eleven bulls were sampled using dacron swabs, pizzle sticks, double-guarded swabs, and semen collection. The microbiomes were dominated by Fusobacteria, Firmicutes, Bacteroidota, Actinobacteria, and Campylobacterota, with semen samples showing the most microbial diversity. Despite differences in operational taxonomic units (OTUs) between methods, there was no significant difference in microbial richness and abundance. The study highlights that T. foetus infections may lead to shifts in the reproductive microbiome, indicating a potential dysbiosis compared to healthy bulls. These findings provide a basis for future research on T. foetus impacts on bovine reproductive health and possible treatment strategies. Tritrichomonas foetus (T. foetus), the causative agent of bovine trichomoniasis, is an obligate protozoan parasite of the bovine reproductive tract and can be found on the penis, prepuce, and distal urethra of the bull and from the cranial vagina to the oviduct in the infected cow. To date, the microbiome of bulls infected with T. foetus has not been described. The objectives of this study were to (1) describe the preputial and penile microbiome of bulls chronically infected by T. foetus, (2) describe the seminal microbiome of T. foetus-infected bulls, and (3) evaluate different collection devices that could be used for sampling. Eleven bulls naturally infected with T. foetus were utilized for the collection of samples. Samples were obtained during the process of a routine breeding soundness exam utilizing either a dacron swab, pizzle stick, double-guarded swab, or semen collection. The preputial and seminal microbiome of T. foetus-infected bulls was dominated by bacterial members of the phyla Fusobacteriota, Firmicutes, Bacteroidota, Actinobacteria, and Campylobacterota. Semen collection yielded the most microbial diversity; however, there was no significant difference between the four methods (p ≥ 0.05). This study characterizes both the preputial and seminal microbial communities of bulls chronically infected by T. foetus. [ABSTRACT FROM AUTHOR]

Introduction and objective: Penis enlargement through substance injection is common in many countries of Southeast Asia and Eastern Europe. The definitive therapy involves removing the entire skin and the subcutaneous tissue and resurfacing the penile shaft via a single-stage or multi-staged procedure. This study aimed to report the functional outcome and esthetics of treating penile paraffinoma patients using the scrotal tunnel + ventral inverted V incision + anastomosis inverted Y technique. Materials and methods: This study was a single-center retrospective descriptive analysis of patients who underwent one-stage scrotal tunnel + ventral inverted V incision and inverted Y-shaped anastomosis procedures from January 2013 to December 2023. The following data were collected: chief complaint, reason for the injection, type of fluid injected, duration of surgery, duration of hospitalization, length of follow-up, and results after surgery. Results: Of the 32 patients included in the study, 78% injected liquids in the form of oil and the goal of the majority of patients was penis enlargement (71%). The average age was 36.84 years, and the main complaint was pain in the penis during erection (53%). The average operation time was 130 minutes, hospitalization duration was 2.21 days, primary wound healing was 91%, patient satisfaction level was 97%, and Scale 4 erection hardness was 91%. Conclusions: One-stage surgery for penile paraffinoma produced promising results when the granuloma was limited to the penis and healthy scrotal skin was available to cover the penis.

Will human sexuality survive the passage to Artificial Intelligence? To answer this question properly, we should first analyze the paradoxical inner structure of sexuality itself, which is never simply binary: it always involves a third element that gives body to the deadlock of sexual difference - this is what Lacan meant by "there is no sexual difference." This is why sexuality is in itself excessive and perverse. For this reason, all attempts to "normalize" sexuality by way of keeping it within the limits of moderation miserably fail: today, we find on the market products deprived of their dangerous element (coffee without caffeine, chocolate without sugar...), and the moderate sexuality is sexuality without sex. The Buddhist attempts to contain the excess sexuality miss the point of sexuality: intense sexuality is in itself the greatest sacrifice (the sacrifice of peaceful moderate life) - in sexuality, we enjoy the pain, the renunciation itself. However, today, in our world pervaded by commodification and technological inventions, real human partners are more and more replaced by what Lacan called lathouses, artificial objects aimed at satisfying our sexual desire without another human being (plastic phalluses, digitalized pornography). The result is that we are thrown into a space of limitless pleasures where, although "everything is permitted," our intense sexual desire gets anaestheticized. [ABSTRACT FROM AUTHOR]

This report explored cases of scabies balanitis involving the glans penis in five men. All the patients complained of genital itching with an associated rash on the penis. Examination revealed an erythematous papular rash on the glans penis in three of the men, while two of them had an erythematous, firm, nodular rash on the glans penis. Scabies balanitis was diagnosed in all cases. The treatment included topical benzyl benzoate (25%) and antihistamines. The lesions resolved after a single application of benzyl benzoate in all cases, except for one patient who had repeated applications of benzyl benzoate (25%) before symptom resolution. The main predisposing factors were unprotected heterosexual intercourse and poor hygiene practices. [ABSTRACT FROM AUTHOR]

Objective: To define the appropriate penile straightening procedures corresponding to the specific penile curvature by comparing the penile length resulting from various straightening procedures in hypospadias repair. Methods: We retrospectively analyzed hypospadias patients between 2017 and 2019. Patients were divided into three groups based on the penile curvature after degloving: <30°, 30°–45°, and >45°. The penile straightening procedures include dorsal plication (DP), simple urethral plate (UP) transection, and UP transection with ventral lengthening (VL). The paired t‐test was conducted for the penile length after fully straightening in each group, simultaneously calculating the length changes (∆T). In addition, the penile length changes among these procedures were compared using Spearman analysis to show the correlation between the penile curvature and the length. Results: The penile length changed significantly after fully straightening in all groups. The length decreased mildly after DP, while increased in the other procedures. The penile curvature after degloving was positively correlated with the absolute change in the penile length (P < 0.001, r = 0.424) and the ratio of ∆T in the original length (P < 0.001, r = 0.433). Conclusion: For hypospadias, the 30° after degloving may serve as the cut‐off for the selection of the straightening method from the perspective of the penile length. For those with < 30°, methods such as DP or UP transection can either be selected. In patients with > 30°, DP should be used with caution because of the potential risk to shorten the penis. In contrast, UP transection effectively corrects the penile curvature and increases the penile length concurrently, which should be primarily recommended in those patients. [ABSTRACT FROM AUTHOR]

The glans clitoris has a corona; however, unlike the corona of the glans penis, the corona of the glans clitoris is practically "nonexistent" as evidenced by the noteworthy absence of its mention and depiction in anatomical and clinical sciences. Accordingly, the corona of the glans clitoris has been neglected in anatomical education and clinical practice. This report details the history regarding the anatomical terminology of the glans and identifies that descriptions of the glans penis, corona of the glans penis, and other penile structures have preceded descriptions of the homologous anatomy of the clitoris by at least a century. Today, recognition of the corona of the glans clitoris, as well as the coronal sulcus and neck of the clitoris should be commonplace. Henceforth, the corona of the glans clitoris and its related anatomy including the sulcus of the glans clitoris and neck of the clitoris should be incorporated into anatomical and clinical language, illustrations, textbooks, education, and practice. Likewise, efforts should be made to propagate knowledge regarding the corona of the glans clitoris, coronal sulcus, and neck of the clitoris to the general public. Giving names to the anatomical structures of the clitoris will undoubtedly increase the awareness of their existence which, in turn, will encourage their clinical assessment and result in decreased morbidity and mortality. Likewise, improved self-awareness of clitoral anatomy will promote self-care which is important in the prevention of disease and the promotion of optimal sexual health. [ABSTRACT FROM AUTHOR]

ABSTRACT Introduction: Although nerves and vessels of the penis play important role in erection, there are few studies on their development in human fetus. Therefore, the objective of the present study is to analyze, quantitatively, in the corpora cavernosa and corpus spongiosum, the development of the nerves and vessels in the fetal penis at different gestational ages. Material and Methods: Fifty-six fresh, macroscopically normal human fetuses aged from 13 to 36 weeks post-conception (WPC) were used. Gestational age was determined by the foot length criterion. Penises were immediately fixed in 10% formalin, and routinely processed for paraffin embedding, after which tissue sections from the mid-shaft were obtained. We used immunohistochemical staining to analyze the nerves and vessels in the corpus cavernous and in the corpus spongiosum. These elements were identified and quantified as percentage by using the Image-J software. Results: The quantitative analysis showed that the percentage of nerves varied from 3.03% to 20.35% in the corpora cavernosa and from 1.89% to 23.88% in the corpus spongiosum. The linear regression analysis indicated that nerves growth (incidence) in the corpora cavernosa and corpus spongiosum correlated significantly and positively with fetal age (r2=0.9421, p

Purpose: To evaluate the expression of core molecular clock genes/proteins in penile cavernous tissue from healthy male subjects and to determine whether their expression has circadian variation. Materials and Methods: Corpus cavernosum biopsy samples were obtained from 10 healthy males with penile deviation or fracture who underwent surgical intervention during the day and night. The daytime group (n=5) underwent corpus cavernosum tissue sampling during zeitgeber time (ZT) 8–12, while the nighttime group (n=5) underwent sampling during ZT 20–24. The expression and localization of BMAL1, CLOCK, PER1, PER2, PER3, CRY1, and CRY2 proteins were analyzed using immunohistochemistry and quantified using H-score analysis. RT-qPCR analysis was performed to assess the expression of core molecular clock genes in the corpus cavernosum tissue of 5 additional daytime patients. Results: The expression of core molecular clock proteins was detected in vascular endothelial cells (VECs) and smooth muscle cells (SMCs) in corpus cavernosum during daytime and nighttime. BMAL1 exhibited the most significant nuclear expression during daytime in both cell types, whereas its expression decreased significantly at night. In VECs, a significant decrease in the nuclear expression of CRY1 was observed at night. In SMCs, a significant decrease in the cytoplasmic expression of PER3 was observed at night. The expression patterns of the core molecular clock genes were ascertained through a RT-qPCR analysis. Conclusions: Our research provides compelling evidence that core molecular clock genes are distinctly expressed in penile tissue in humans. Furthermore, we observed the expression of molecular clock proteins within the VECs and SMCs of the corpus cavernosum, with BMAL1 being the most prominently expressed. The discovery of core molecular clock genes in penile tissue, as well as proteins within the SMCs and VECs of the corpus cavernosum, introduces the potential significance of the molecular clock mechanism in the physiology of penile erection.

ABSTRACT Purpose: To answer the question of whether it is possible to achieve complete corporal covering of the urethral closure using incomplete penile disassembly in classic bladder exstrophy. We hypothesize that mobilization of the corpora under Buck's fascia, their dorsal translocation through the incisions in Buck's fascia and suturing corporal convex sides above the urethra would allow extend corporal covering of the urethra, reducing the risk of urethra-cutaneous fistula formation. Materials and Methods: A prospective follow-up on all boys who underwent the modified Cantwell-Ransley primary penile reconstruction was conducted. Inclusion criteria comprised bladder exstrophy closure in our institution, ensuring a postoperative follow-up period of no less than 24 months. The key innovation of the technique lies in a deep dissection of the dependent corpora under Buck's fascia, followed by their dorsal relocation through extended dorsal incisions in Buck's fascia, and limited external corporal rotation 90 degrees only at the base of the penis. Results: Between November 2019 and March 2022, 18 boys aged 11 to 35 months met the inclusion criteria and underwent the modified penile reconstruction. Surgical procedures and postoperative period did not include any major complications. Total corporal covering of the urethral sutures was achieved in 15 of 18 patients. No urethra-cutaneous fistulas were observed within 2 years of follow-up. All individuals demonstrated spontaneous erections, and the absence of dorsal curvature was documented. Conclusion: The modified technique of incomplete penile disassembly applied in a homogenous group of patients with classic bladder exstrophy allows penile shaft elongation, improved aesthetic outcomes, preserved erections, and eliminates dorsal curvature. The technique demonstrated feasibility and reliability while maintaining positive effects on tissue circulation. The absence of urethra-cutaneous fistulae is attributed to the complete corporal covering of the urethral sutures and supports the initial hypothesis.

‘I would not have given it for a wilderness of monkeys’: so, says The Merchant of Venice’s Shylock, referencing the ring gifted to him by his late wife, Leah, now stolen by his errant daughter, Jessica. An odd pronouncement for a character often read as an exemplar of exchange values for whom everyone and everything has its price. Excepting, of course, Leah’s ‘turquoise’. The implied use value of which repositions Shakespeare’s most uncomfortable stereotype – Shylock as the Jewish usurer – as a critic, rather than comprador, of early modern Capital, thereby anticipating not only Marx but Freud. For at stake in The Merchant of Venice is nothing less than the surplus-jouissance of the Capitalist’s discourse itself, coincident with, but ultimately defined against the ‘jewish-ssance’ of Shylock. This article will draw upon the insights of psychoanalysis, as well as those of political economy to examine the status of value, love, and law in The Merchant of Venice, arguing that Shylock may be not only Capitalism’s fiercest critic, but its most misunderstood psychotherapist.

Erectile dysfunction (ED) refers to the inability of the penis to maintain a firm erection during sexual activity. Mucuna, or M. pruriens, contains levodopa, a compound showing promise in ED treatment. However, formulating Mucuna extract into tablet dosage forms is challenging due to its semisolid nature. This study aimed to develop sustained-release tablets containing Mucuna extract via semisolid extrusion 3D printing. Eudragit RS PO (Eudragit) served as a sustained-release polymer, with poly (vinyl alcohol) (PVA) as a co-polymer for forming the tablet matrices. This study had the following two main phases: screening, which identified the factors affecting the printability, and optimization, which focused on the factors influencing the levodopa release and its consistency. The results showed that both the polymeric solid percentage content (PSPC) in the semisolid slurry and the Eudragit-PVA ratio significantly affected the printability. All of the formulations were printable, and the PSPC and Eudragit-PVA ratios were incorporated into the optimized model. The desired formulation, achieving targeted levodopa release and consistency, had a PSPC of 58.8% and a Eudragit-PVA ratio of 2.87:1. In conclusion, semisolid extrusion 3D printing guided by the design of experiments (DoE) proved feasible for producing reliable 3D-printed tablets with consistent active ingredients and desired release rates.

Urethral Trauma is a discontinuity of urethra which caused by external stress (pelvic fracture or straddle injury) or internal stress (catheter placement, urological procedures). There are several suitable techniques, including immediate exploration or urine diversion. The treatment used depend on the cause of the rupture, rupture length, as well as anatomical position of the rupture. A 46-year-old male suddenly presented with swollen penile and testicle after 1 day of hospitalization. One day before, patient suffers in high-speed motorcycle accident and sustains blunt trauma to the perineal area, hitting the handle bar of the motorcycle and brought to the emergency department. There was a palpable bladder distension during physical exam, with penis and scrotum enlargement. Laboratory findings show elevated WBC and elevated creatinine level. Urinalization test was within normal limit. Partial laceration found during urethroscopy approximately <1cm in size. Scrotal drainage and exploration are conducted due to scrotum being swollen progressively. There is uncertainty regarding these symptoms to be interpreted as a urethral injury because some of the classical symptoms are missing, although patient showed with palpable bladder distension. Due to the swollen penis and scrotum which are enlarged progressively, urethroscopy and scrotal exploration was performed. Small laceration on the bulbar area of the urethra is found, indicating anterior urethral rupture, the laceration is treated conservatively with the placement of transurethral catheter. Scrotal exploration then performed which pus and extravasation of urine is found within the scrotum. The precision on determining anterior urethral rupture as a diagnosis decides the management, prognosis and complication rate of anterior urethral rupture. Although, the initial urethral trauma management remains disputed, a bulbous urethral rupture with a complication of extravasation of urine into the penis and scrotum can be treated effectively with urine diversion and scrotal exploration.

Reproductive problems in cattle are frequent and have an important impact on production. In addition, inflammatory, traumatic and other diseases may be followed by the development of tumours, which are a cause of culling of breeding males. The main types of tumours diagnosed in the bull penis are fibropapilloma and squamous cell carcinoma. The aim of this study was to characterize a case of a tumour in the glans penis of a bull from a dairy farm in Santa Fe, Argentina. The neoplastic tissue was stained with haematoxylin and eosin and then analysed by immunohistochemistry to reveal its characteristic phenotype. Results showed positivity to vimentin, neuron specific enolase, proliferating cell nuclear antigen, S100 and glial fibrillary acidic protein. This suggested that the tumour was a neoplasm of neural origin, classified as neurofibrosarcoma, a peripheral nerve sheath tumour, here reported in the penis of a bull for the first time.

Penile lymphoma is a rare entity. Patients are often elderly, and present with an ulcerated painless mass on the shaft of the penis, strongly mimicking the more common diagnoses of infection, trauma or squamous cell carcinoma. Examination, radiological investigation and ultimately biopsy of the lesion is essential in making the diagnosis and guiding treatment. Herein, we present a case of diffuse large B cell lymphoma in the penis of an elderly gentleman, and review the salient histopathology regarding this uncommon entity. [ABSTRACT FROM AUTHOR]

Background. Male circumcision (MC) is a practice involving the surgical excision of the foreskin to expose the glans and it is often performed for religious reasons. Ritual circumcision is frequently carried out by unqualified practitioners in inadequate settings, which can also lead to the death of the individual. Case Report. A 28-day-old infant was undergoing circumcision by a man that performed the circumcision using a razor blade. During the same day, the child experienced continuous bleeding from the wound and, finally, died after about 20 hours. At autopsy, a cutaneous sharp injury was revealed with ablation of the foreskin and part of the penile body. The lesion had irregular and jagged margins, with diffuse hemorrhagic infiltration. The glans and upper fascia of the penis appeared edematous and hyperemic and there were abundant hemorrhagic infiltrations in the frenulum area. The child's death was attributed to hemorrhagic shock in a child undergoing genital mutilation surgery. The finding of a significant hemorrhagic infiltration of the frenulum region indicated that the frenular artery had been severed. Conclusions. Around 35% of ritual male circumcisions are performed clandestinely in Italy, and typically by unqualified practitioners. In such events, the forensic investigation of the injuries inflicted on the victim allows for determining whether the procedure was performed appropriately or not, to verify the existence of a causal link between the procedure itself and the death of the individual.

A new monoterpene derivative namely dongsunol A (1) and sixteen known compounds (2–17) were isolated from the volva of Phallus dongsun. All compounds were isolated from this fungus for the first time. Their structures and absolute configurations were determined by nuclear magnetic resonance (NMR), HRESIMS spectral data, and electronic circular dichroism (ECD). The new monoterpene derivative (1) exhibited antibacterial activity with a MIC of 200 μg/mL. Other compounds have inhibitory effects on Staphylococcus aureus and Pseudomonas aeruginosa, while have displayed moderate NO inhibitory activity and antineoplastic activity on SMMC-7721 and SW480 in vitro.

Background Inguinal lymph node dissection plays an important role in the management of melanoma, penile and vulval cancer. Inguinal lymph node dissection is associated with various intraoperative and postoperative complications with significant heterogeneity in classification and reporting. This lack of standardization challenges efforts to study and report inguinal lymph node dissection outcomes. The aim of this study was to devise a system to standardize the classification and reporting of inguinal lymph node dissection perioperative complications by creating a worldwide collaborative, the complications and adverse events in lymphadenectomy of the inguinal area (CALI) group. Methods A modified 3-round Delphi consensus approach surveyed a worldwide group of experts in inguinal lymph node dissection for melanoma, penile and vulval cancer. The group of experts included general surgeons, urologists and oncologists (gynaecological and surgical). The survey assessed expert agreement on inguinal lymph node dissection perioperative complications. Panel interrater agreement and consistency were assessed as the overall percentage agreement and Cronbach's α. Results Forty-seven experienced consultants were enrolled: 26 (55.3%) urologists, 11 (23.4%) surgical oncologists, 6 (12.8%) general surgeons and 4 (8.5%) gynaecology oncologists. Based on their expertise, 31 (66%), 10 (21.3%) and 22 (46.8%) of the participants treat penile cancer, vulval cancer and melanoma using inguinal lymph node dissection respectively; 89.4% (42 of 47) agreed with the definitions and inclusion as part of the inguinal lymph node dissection intraoperative complication group, while 93.6% (44 of 47) agreed that postoperative complications should be subclassified into five macrocategories. Unanimous agreement (100%, 37 of 37) was achieved with the final standardized classification system for reporting inguinal lymph node dissection complications in melanoma, vulval cancer and penile cancer. Conclusion The complications and adverse events in lymphadenectomy of the inguinal area classification system has been developed as a tool to standardize the assessment and reporting of complications during inguinal lymph node dissection for the treatment of melanoma, vulval and penile cancer.

Background Methods Results Conclusions Level of evidence Extramammary Paget's disease (EMPD) is a rare intra‐epidermal adenocarcinoma, and reconstruction of the penoscrotal region remains a clinical challenge. The superficial circumflex iliac artery perforator (SCIP) flap has been successfully used as a free flap, while its application as a propeller flap in the reconstruction of penoscrotal EMPD defect is rarely reported. The objective was to evaluate the safety and efficacy of the SCIP propeller flap in the reconstruction of penoscrotal defects in EMPD.Between September 2010 and August 2022, consecutive patients diagnosed with penoscrotal EMPD were enrolled. All patients underwent penoscrotal EMPD excision and reconstruction with SCIP propeller flap combined with other flaps or skin grafts on individual defects. Demographic information, surgical parameters, postoperative complications, patient satisfaction, and recurrence rates were analyzed.Twenty‐four patients (mean age, 73 ± 8.8 years; mean BMI, 23.98 ± 3.62 kg/m2) with 33 SCIP propeller flaps (mean size 120.1 cm2; range, 24–208 cm2) were included, and the mean defect size was 67.4 cm2 (range, 12–255 cm2). The mean operative duration was 385.4 ± 146.8 min. Fifteen patients received autologous full‐thickness skin grafts, and four received other flaps simultaneously. All flaps survived without total or partial loss, and all donor sites achieved primary closure, though local hematoma (one case) and limited skin graft necrosis (two cases) were observed. All patients experienced complete wound healing and maintained penoscrotal morphology and function without recurrent lesions over a mean follow‐up of 59 months.The SCIP propeller flap seems a safe and effective reconstructive method for penoscrotal EMPD.IV.

Introduction: Division of the suspensory ligament of the penis has emerged as a popular surgical approach for penile lengthening, but accurate preoperative predictions of lengthening outcomes remain elusive. This study aimed to identify readily measurable anatomical parameters associated with post-ligamentolysis penile length gain, facilitating more reliable preoperative estimations. Methods: An experimental cross-sectional study was performed on 16 adult cadavers. Data collected before dissection included: age at death, ethnicity, height, length of the penis before dissection and width of the suspensory ligament of penis. Following the complete dissection of the suspensory ligament of penis, the depth of the pubic symphysis and the penile length after the procedure were measured. The absolute and relative length differences pre- and post-ligamentolysis were calculated. Correlation coefficients were used to study relations between these variables. Results: Penile length increased uniformly after complete division of the suspensory ligament (average gain: 26.38 mm, SD = 14.83 mm; range 4–60 mm). Pearson correlation revealed a significant negative correlation between pre-ligamentolysis penile length and post-ligamentolysis increase (r = − 0.601; p = 0.014), suggesting greater gains in individuals with shorter pre-ligamentolysis lengths. Age, ligament width, and pubic arch depth showed no significant correlations. Ethnicity did not impact post-ligamentolysis length increase (t = − 0.135; p = 0.894). Conclusions: This study highlights the potential to predict penile length gain post-ligamentolysis through measurable anatomical parameters. The ability to anticipate the outcome of this procedure could empower surgeons to provide informed counseling, potentially elevating patient satisfaction. An experimental cross-sectional study was performed to investigate the outcomes of penile lengthening surgery Penile lengthening was achieved in all subjects via complete dissection of the suspensory ligament of the penis Penile length increase may be predicted preoperatively using easily measurable anatomical parameters No Level Assigned: This journal requires that authors assign a level of evidence to each submission to which Evidence-Based Medicine rankings are applicable.

OBJECTIVE This is the first study to determine whether there is a relationship between penile bulb radiation dose and urinary incontinence. METHODS This study comprises 131 patients with localized, locally advanced, and pelvic oligometastatic prostate cancer treated at our institution. All patients were treated with IMRT between February 2016 and August 2020. Urinary incontinence after the treatment was assessed retrospectively using a standardized follow-up program based on data available at our center. The urinary incontinence was scored using the CTCAE version 5.0 scoring system. In univariate analysis, the Mann-Whitney test was used to detect any association between penile bulb V50 doses and membranous urethral length on urinary incontinence. RESULTS Urinary incontinence after the treatment was reported in 17 of 131 patients. The average penile bulb V50 values of patients with incontinence were 28.66 gy and 26.8 in patients who did not have urinary incontinence. The mean membranous urethral length was 3.01cm in patients with incontinence and 3.34cm in patients without incontinence. Although these parameters have minimal difference in patients with and without incontinence, they are not statistically significant (p>0.05 all). CONCLUSION Radiation-induced urinary incontinence was not associated with the radiation dose of the penile bulb and membranous urethral length. However, further studies are essential.

The Temminck's pangolin (Smutsia temminckii) is one of eight pangolin species worldwide and the only pangolin present in southern Africa. Historically, pangolins have not been able to reproduce successfully in captivity and this may be in part due to the lack of knowledge and understanding with regards to the pangolin reproductive system (anatomy, physiology, biology) in all eight species. This original study describes the gross anatomy of the male Temminck's pangolin from three adult individuals investigated. The male Temminck's pangolin presented a short, conical penis with ascrotal (internal) testes, similar to many other myrmecophagous mammals such as the aardvark (Orycteropus sp.) and anteaters (suborder: Vermilingua). However, the orientation of the penis of the Temminck's pangolin differed in that it was oriented cranioventrally, in contrast to the caudal orientation of the giant anteater. The testes were found to be bilaterally flattened with an elongate oval shape, similar to the aardvark. The specific characteristics of the reproductive tract of the male Temminck's pangolins are thought to be adaptations to their peculiar lifestyle as the male portrays characteristics that indicate adaptation to a lower basal metabolic rate and body temperature as well as to their defensive mechanism of rolling up into a ball. Our study suggests the male Temminck's pangolin reproductive anatomy is most similar and comparable to the Xenarthrans and the aardvark that display the same fossorial activities as pangolins, and the male morphology is not comparable to the phylogenetically closely‐related Carnivora.

Simple Summary: A new genus of empidine dance fly, namely Rhamphempis, is described with five new species included. The new genus is recorded from French Guiana and the United States of America. The peculiar disjunct geographic distribution of Rhamphempis is discussed. The genus Rhamphempis gen. nov. (Diptera: Empididae: Empidinae: Empidini) is described and includes the following five new species from French Guiana and the USA: Rhamphempis concava sp. nov. (France: French Guiana, Roura); R. distincta sp. nov. (France: French Guiana, Roura); R. mirifica sp. nov. (France: French Guiana, Régina); R. montreuili sp. nov. (Type species, France: French Guiana, Mitaraka, Roura, St-Georges-de-l'Oyapock); and R. septentrionalis sp. nov. (USA: Maryland, College Park). The genus differs from other empidine genera by the following combination of characters: scape and postpedicel lengthened, proboscis long, strongly sclerotised with labella as long as prementum bearing annulations, wing with R2+3 somewhat shortened, more or less recurved at pterostigma, R4+5 unforked, base of abdomen yellowish in male, brownish to blackish in female, male pregenital segments strongly modified and postabdomen more or less downcurved, presence of large surstylus, very fine and long phallus. The genus is fully illustrated and keyed along with a discussion of its peculiar disjunct geographic distribution and its phylogenetic relationship within the tribe Empidini. [ABSTRACT FROM AUTHOR]

Background: Peyronie's disease (PD) is a localized fibrosis of tunica albuginea, which causes the anatomical and functional changes to the penis. Corporoplasty with grafting is indicated in severe (>60°) and complex curvature. Buccal mucosa is the most favored autologous graft material nowadays. The ventrolateral aspect of lingual mucosa has similar histological features to the rest of the oral cavity. Methods: This study aimed to test the efficacy, safety, durability, and reproducibility of corporoplasty with lingual mucosal graft (LMG) in the surgical treatment of PD in terms of surgical outcome, sexual function, and donor site complications. This prospective study included 19 patients of PD with severe and complex curvature, who underwent corporoplasty with LMG. Surgical and functional outcomes were assessed at follow-up planned at 2 weeks, 3 months, 6 months, 1 year, and 2 years. Results: The mean operative time was 126.31 ± 21.45 min. Additional Nesbit's plication to correct the residual deformity was required in 26% (5 / 19) of patients. Straightening of the penis (curvature <10°) was achieved in 89% (17 / 19) of patients. Increase in the penile length (>1 cm) postoperatively was achieved in 63% (12 / 19) of patients and a shortening of penis occurred in 5% (1 / 19) of patients. Newer onset erectile dysfunction developed in 11% (2 / 19) of patients, and patient and partner satisfaction rates were 89% (17 / 19) and 84% (16 / 19), respectively, in a mean follow-up of 20.66 ± 5.37 months. Donor site complications were minimal and no patient had any salivary changes or speech disturbances. Conclusion: LMG provided excellent short-term results in terms of deformity correction, improved sexual function, and minimal donor site morbidity. The method is simple and reproducible, and multicenter studies with larger number of cases with longer follow-up are required to confirm these favorable results. [ABSTRACT FROM AUTHOR]

The human penile and clitoral development begins from a morphologically indifferent genital tubercle. Under the influence of androgen, the genital tubercle forms the penis by forming a tubular urethra within the penile shaft. Without the effect of the androgen, the genital tubercle differentiates into the clitoris, and a lack of formation of the urethra within the clitoris is observed. Even though there are similarities during the development of the glans penis and glans clitoris, the complex canalization occurring along the penile shaft eventually leads to a morphological difference between the penis and clitoris. Based on the morphological differences, the main goal of this study was to define the vascular and neuronal anatomy of the developing penis and clitoris between 8 and 12 weeks of gestation using laser scanning confocal microscopy. Our results demonstrated there is a co‐expression of CD31, which is an endothelial cell marker, and PGP9.5, which is a neuronal marker in the penis where the fusion is actively occurring at the ventral shaft. We also identified a unique anatomical structure for the first time, the clitoral ridge, which is a fetal structure running along the clitoral shaft in the vestibular groove. Contrary to previous anatomical findings which indicate that the neurovascular distribution in the developing penis and clitoris is similar, in this study, laser scanning confocal microscopy enabled us to demonstrate finer differences in the neurovascular anatomy between the penis and clitoris.

Male harvestmen penial armature has a remarkable morphology; however, it is poorly known regarding its functions. We examined the male genitalia of virgin and mated males of the gonyleptid Pachyloides thorellii under Scanning Electron Microscope looking for evidence that the penis could remove sperm from the female ovipositor lumen during mating. Micrographs show sperm agglutinations over and within the microsetae fields in six out of the 12 mated males studied. For the mating experiments we used only virgin females, therefore the sperm found in the penis was in all cases their own sperm. This self-sperm removal could be the extraction of sperm excess in cooperation (or not) with the females. This is the first study to show for the Order Opiliones direct evidence that a male penis contains structures that can effectively remove sperm from the female ovipositor. Further behavioral and morphological studies are needed to confirm the conditions of occurrence and participation of each sex in sperm removal processes in this species. [ABSTRACT FROM AUTHOR]

Genitourinary tuberculosis (GUTB), especially penile tuberculosis (PTB), is a disease often overlooked by urological specialists, especially in Europe, where the pathology is less frequent. In this report, we described a case of penile tuberculosis (PTB) characterized by ulcers on the penis. After the patient was administered three months of anti-tuberculosis treatment (isoniazid 0.3 g/qd, rifampicin 0.6 g/qw, and ethambutol 0.75 g/qd), the ulcer disappeared. The patient was followed up for seven months and showed no recurrence. [ABSTRACT FROM AUTHOR]

Neoplasm of the penis is relatively rare in most regions representing 0-2% of cancers worldwide. While the penis can be affected by sarcomas, basal cell carcinomas or even melanoma, Penile Squamous Cell Carcinoma (PSCC) represents approximately 95% of all penile neoplasms. Despite its rarity and most common presentation at later decades of life most individuals diagnosed with PSCC are faced with significant decrease in quality of life. The prevalence and incidence vary among different regions and populations, but a common trend is for diagnosis to occur late (stage 4). Underdeveloped countries are traditionally reported to have higher incidence rates; however, rates may vary significantly between urban and rural areas even in developed countries. Age adjusted rates are on the rise in some countries that used to have incidence rates of 1:100 000 or less. The list of associated risk factors is long and includes among others, lack of neonatal circumcision, poor genital hygiene, socioeconomic status, history of human papillomavirus (HPV) infection and penile intraepithelial neoplasia (PeIN). Many risk factors are widely debated among experts however HPV and PeIN are indisputable risk factors, and both also form part of the classification system for PSCC. Both conditions may have occurred in the past or be present at the time of diagnosis and identifying them plays a major role in management strategies. For such a rare condition PSCC can present in many different forms clinically making diagnosis no easy feat. Diagnosis of PSCC is done through clinical examination, including lymph node palpation, followed by a biopsy, which is essential for the classification. Lymph node involvement is a common finding at first presentation and investigation of spread to deep nodes is important and can be done with the aid of PET-CT. Treatment options for PSCC include surgery, chemotherapy, and radiation therapy. Surgical removal of the tumor is considered the most effective however can lead to severe decrease of quality of life. Chemotherapy is used in the case of fixed or bulky lymph nodes, where surgery is not indicated, and for distant metastasis. Radiation therapy is particularly effective in the case of HPV-positive PSCC. [ABSTRACT FROM AUTHOR]

Background: Primary testicular lymphoma (PTL) is relatively rare. The contralateral testis is a common site of PTL relapse; therefore, once complete remission is achieved, radiation therapy (RT) is administered to the contralateral testis to prevent relapse. Case presentation: A 76-year-old man was diagnosed with PTL and received RT as described above. However, despite achieving and maintaining complete remission, a mass diagnosed as diffuse large B-cell lymphoma by tissue biopsy developed in the glans penis 6.5 years after prophylactic RT. We investigated whether the glans penile lymphoma was PTL relapse or a new malignancy by genomic analysis using next-generation sequencing of DNA extracted from two histopathological specimens. Conclusions: We found the same variant allele fraction in four somatic genes (MYD88, IL7R, BLNK, and FLT3) at similar frequencies, indicating that the glans penile lymphoma had the same origin as the PTL. To the best of our knowledge, this is the first case report of PTL relapse in the glans penis. [ABSTRACT FROM AUTHOR]

Miroculis (Ommaethus) Savage and Peters, 1983 (Ephemeroptera, Leptophlebiidae) is reviewed based on fresh material from Southeastern Brazil and on type specimens. Miroculis (Ommaethus) cipoensis sp. n. is described based on male and female imagos from Serra do Cipó, Minas Gerais State, Brazil. It can be distinguished from other species of the subgenus based on the following characteristics: forewings with membrane brown and dark brown mark around cross veins; hind wing uniformly brown; forceps segment I light brown, segment II and III lighter; penis lobe long (at least ⅔ of forceps segment I) and apically rounded and curved on apical ¼; length of body between 5.0 and 6.3 mm. Photographs of fresh material belonging to M. (O.) froehlichi Savage and Peters, 1983 and M. (O.) mourei Savage and Peters, 1983 are provided, clarifying the boundaries between the existing species of the subgenus. Based on that, M. (O.) misionensis Domínguez, 2007 is considered a junior synonym of M. (O.) mourei. A key to the male imagos of the subgenus is presented, as well as a distributional map with updated records of the species. [ABSTRACT FROM AUTHOR]

Background: The erectile dysfunction (ED), which is the inability to achieve and/or sustain a penile erection sufficient to result in a satisfying sexual performance, represents a very common complaint. for men over forty years old. The aim of the study was to evaluate if Flat Magnetic Stimulation (FMS) technology could help individuals with symptomatic erectile dysfunction. Methods: Twenty patients with erectile dysfunction, underwent eight sessions of about 30 minutes each in a twice a week frequency with the study device. During treatments, every potential side effect was assessed. The International Index of Erectile Function (IIEF) was compiled by all patients at the beginning, after the eighth treatment and at 1 month from the end of the last treatment. The questionnaire scores were presented as median values along with the interquartile range (IQR) and we set the significance threshold at 0.01. Results: After the treatment and at 1-month follow-up, the increase in questionnaire scores was statistically significant compared to the baseline, thus supporting the clinical usefulness of this treatment. In particular, the result of the study indicates a statistically significant difference between IIEF score before treatment (Median = 34) and IIEF score after the end of treatment (Median = 45) and between IIEF score before treatment and IIEF score at 1-month follow-up (Median = 54). Conclusions: The study findings showed that FMS represents a promising treatment option to individuals affected by symptomatic erectile dysfunction. [ABSTRACT FROM AUTHOR]

Introduction: Traditional anatomy-based penile venous surgery is deemed inadequate. Based on revolutionary insights into penile vasculature, penile venous stripping (PVS) shows promise in treating adolescent erectile dysfunction (AED). We aimed to report on this novel approach. Methods: We conducted a retrospective analysis of 223 individuals under 30 diagnosed with veno-occlusive dysfunction (VOD) between 2009 and 2023. Among them, 83 were diagnosed with AED and divided into the PVS (n = 37) and no-surgery (NS, n = 46) groups. All participants had been dissatisfied with conventional therapeutic options. Dual pharmaco-cavernosography was the primary diagnostic modality. PVS involved stripping the deep dorsal vein and two cavernosal veins after securing each emissary's vein with a 6-0 nylon suture. Erection restoration was accessed using the abridged five-item version of the International Index of Erectile Function (IIEF-5) score system and the erection hardness scale (EHS). Statistical analysis was performed using IBM SPSS 21.0. Results: There were significant differences (both p < 0.001) between the preoperative and postoperative IIEF-5 scores in the PVS and NS groups (9.8 ± 3.0 vs. 20.4 ± 2.2; 9.9 ± 2.5 vs. 9.5 ± 2.1), as well as in the EHS scores (1.7 ± 0.7 vs. 3.5 ± 0.6 and 1.8 ± 0.5 vs. 1.3 ± 0.4). The satisfaction rate was 87.9% (29/33) in the PVS group and 16.7% (17/41) in the NS group. Conclusions: AED can be effectively treated using physiological methods, although larger patient cohorts are needed for validation. [ABSTRACT FROM AUTHOR]

Fathering a child does not just confer a new identity on a Nigerian man, it encapsulates the essence of his existence. Although male infertility negatively impacts sterile men’s masculinity, it is rarely studied as such. This study focuses on the struggles of the nonvirile man in a culture where his existence is deeply rooted in virility. Using Corpus Linguistics and Critical Discourse Analysis. I examine how the pronoun “I” and its Ngram realizations are used to express the male character’s personal struggles with infertility in Ayobami Adebayo’s Stay with Me. I conclude that an erect phallus is crucial to a male’s positive self-appraisal and self-actualization in Nigeria. [ABSTRACT FROM AUTHOR]

Background The endothelial glycocalyx is an important barrier that protects the structure and function of endothelial cells. Androgen deficiency is a common factor that causes structural and functional impairment of endothelial cells. Aim To investigate changes in the endothelial glycocalyx in the penile corpus cavernosum of the rat with low androgen status and its relationship with erection function. Methods Eighteen 10-week-old Sprague-Dawley male rats were randomly divided into 3 groups (n = 6 each): sham operation, castration, and castration + testosterone replacement. The maximum intracavernosal pressure/mean arterial pressure of the penis was measured after modeling for 4 weeks. The expression levels of endothelial nitric oxide synthase (eNOS), phospho-eNOS, syndecan 1, heparanase, and nitric oxide in penile cavernous tissue and the serum levels of heparan sulfate, hyaluronic acid, tumor necrosis factor α, and interleukin 6 were determined. Transmission electron microscopy was used to observe the ultrastructure of the endothelial glycocalyx in penile tissue. Outcomes The thickness of the endothelial glycocalyx in the penile corpus cavernosum of castrated rats was significantly lower than that of the control group. Results In the castrated rats, the endothelial glycocalyx thickness, syndecan 1 level, ratio of phospho-eNOS to eNOS, nitric oxide level, and maximum intracavernosal pressure/mean arterial pressure (3 V, 5 V) were significantly lower than those in the sham group (P  < .05). The expression of heparanase and the serum levels of tumor necrosis factor α and interleukin 6 were significantly higher in the castrated group than in the sham group (P  < .05). Clinical Translation Upregulating the expression of the endothelial glycocalyx in the penile corpus cavernosum may be a new method for treating erectile dysfunction caused by low androgen levels. Strengths and Limitations This study confirms that low androgen status promotes the breakdown of the endothelial glycocalyx. However, further research is needed to determine whether androgens are related to the synthesis of the endothelial glycocalyx. Conclusion Low androgen status may suppress the level of nitric oxide in the cavernous tissue of the penis via impairment of the endothelial glycocalyx, resulting in inhibited erection function in rats.

Vasculogenic erectile dysfunction (ED) is the most common form of ED affecting the male population. Once the first line investigation for erectile dysfunction, penile Doppler ultrasound examinations have reduced in number following the introduction of oral phosphodiesterase inhibitors as a treatment method. As such, skilled professionals versed in the performance of these examinations are dwindling. This skill deficit is compounded by the lack of standardisation that exists in the performance and interpretation of penile haemodynamics relative to impotence of vascular origin. Despite the success of pharmacological agents in the treatment of vasculogenic dysfunction, penile Doppler examinations are still relevant in the assessment of ED in non‐responders, and those patients in which pelvic surgery or trauma has altered the normal erectile mechanism. Growing evidence in the literature also suggests that vasculogenic ED may be an early indicator of systemic vascular disease and therefore prognostic of future cardiovascular events. Considering this, the relevance of Doppler assessment of penile haemodynamics with ultrasound should not be underestimated. This article will introduce the sonographer to advanced vascular anatomy of the penis, pathophysiology of erectile function and the principles of normal and pathological penile haemodynamic patterns. It also aims to suggest a standardised protocol for the performance of penile Doppler ultrasound relative to primary vasculogenic ED and reduce the amount of variability that exits between operators. As such the sonographer can make a significant contribution to patient management pathways. [ABSTRACT FROM AUTHOR]

This study aimed to elucidate the influence of various culture medium components, including carbon sources, nitrogen sources, inorganic salts, suspension agents, and temperature, on the mycelial growth characteristics of Phallus dongsun. Employing single-factor experiments and response surface methodology within glass Petri dishes, the research identified that carrot powder, soybean powder, and ZnSO4 notably enhanced the proliferation of aerial mycelium, significantly augmenting the growth rate of P. dongsun mycelium. The resultant mycelium was observed to be dense, robust, and fluffy in texture. In particular, ZnSO4 markedly accelerated the mycelium growth rate. Furthermore, xanthan gum was found to effectively modulate the medium's viscosity, ensuring a stable suspension and facilitating nutrient equilibrium. The optimal cultivation temperature was determined to be 25°C, with mycelial growth ceasing below 5°C and mycelium perishing at temperatures exceeding 35°C. The optimal medium composition was established as follows: wheat starch 5 g/l, carrot powder 5 g/l, soybean powder 7.50 g/l, glucose 10 g/l, ZnSO4 0.71 g/l, NH4Cl 0.68 g/l, xanthan gum 0.5 g/l, and agar 20 g/l. Under these optimized conditions, the mycelium of P. dongsun exhibited a rapid growth rate (1.04 ± 0.14 mm/day), characterized by a thick, dense, and well-developed structure. This investigation provides a theoretical foundation for the conservation, strain selection, and breeding of P. dongsun. [ABSTRACT FROM AUTHOR]
