To determine if removing an ovary for ovarian tissue cryopreservation (OTC) increased rates of primary ovarian insufficiency (POI) in girls undergoing bone marrow transplantation (BMT). Institutional review board approval was obtained by all three clinical sites.Multi-center retrospective cohort study SETTING: Academic children's hospitals PATIENTS: Females aged 2-21 who underwent BMT with or without OTC, from years 2010 to 2017.None MAIN OUTCOME MEASURES: Rates of POI in girls who underwent OTC versus those who underwent BMT alone as determined by serum markers, presence of menses, or clinical diagnosis.A total of 142 patients were identified, 43 who had OTC and 99 with BMT alone. Rate of POI in girls undergoing OTC was 65% versus 41.8% in those who underwent BMT alone (p=0.26).Although this study was not powered to detect lack of difference, it is reassuring that there does not seem to be a clinically significant increase in POI in patients undergoing OTC.

Gender-affirming hormones and/or surgeries seeking to change the body can have potentially lasting effects. Changes in requests for these therapies among gender-diverse youth are not well-understood. The study aim is to characterize factors associated with shifts in gender-related medical requests.This mixed-methods study used retrospective chart review and qualitative interviews with clinicians. Of 130 youth receiving clinical gender care at Children's National Hospital, 68 met inclusion criteria. Qualitative interview analysis was performed to identify patterns and themes around shifts in gender-related medical requests over time. Statistical analysis employed chi-square and t-tests to compare characteristics in the shift versus no-shift groups and kappa statistics to calculate qualitative coding agreement.Of the 68 youth followed over time (mean age 15.11 years, 47% autistic, 22% nonbinary), 20 (29%) reported a shift in request. No significant differences were found by age, autism status, or designated sex at birth. More youth with shifts were nonbinary (p = .012). Six shift profiles were identified from qualitative interviews with excellent reliability (κ = 0.865). Four of the profiles reflect shifts in request prior to starting treatment (85% sample); two involved shifts after commencing treatment (15%). The most common profile reflected a medical request that was made, withdrawn, and re-requested (45%).Shifts in gender-affirming medical requests by gender-diverse youth may not be uncommon during the adolescent's gender discernment process, and may more likely occur among nonbinary youth. Many individuals who experience shifts away from medical treatment may later resume the request.

Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders of steroidogenesis of the adrenal cortex, most commonly due to 21-hydroxylase deficiency caused by mutations in the CYP21A2 gene. Although women with CAH have decreased fecundity, they are able to conceive; thus, if pregnancy is not desired, contraception options should be offered. If fertility is desired, women with classic CAH should first optimize glucocorticoid treatment, followed by ovulation induction medications and gonadotropins if needed. Due to the possible pregnancy complications and implications on the offspring, preconception genetic testing and counseling with a high-risk obstetrics specialist is recommended. For couples trying to avoid having a child with CAH, care with a reproductive endocrinology and infertility specialist to utilize in vitro fertilization can be offered, with or without preimplantation genetic testing for monogenic disorders. Prenatal screening and diagnosis options during pregnancy include maternal serum cell free-DNA for sex of the baby, and chorionic villus sampling and amniocentesis for diagnosis of CAH. Pregnant women with classic CAH need glucocorticoids to be adjusted during the pregnancy, at the time of delivery, and postpartum, and should be monitored for adrenal crisis. Maternal and fetal risks may include chorioamnionitis, maternal hypertension, gestational diabetes, cesarean section, and small for gestational age infants. This review on CAH due to 21-hydroxylase deficiency highlights reproductive health including genetic transmission, contraception options, glucocorticoid management, fertility treatments, as well as testing, antenatal monitoring, and management during pregnancy, delivery, and postpartum.

To assess genital symptomatology, characterize the findings of genital examination, and describe the incidence and treatment of vulvovaginal graft-versus-host disease (vvGvHD) in girls and adolescents after allogeneic hematopoietic stem cell transplantation (HSCT).Retrospective cohort.Metropolitan-area children's hospital.Female allogeneic HSCT recipients ages 0 to 22 years.Genital symptoms, genital examination, diagnosis, and treatment of vvGvHD.A total of 57 participants were included in the analysis. The median age at the time of HSCT was 10 years (range 4 months-23 years). Most (n = 40, 71%) underwent transplant for a nonmalignant condition, most commonly sickle cell anemia (n = 19, 33%). The median time of onset of GvHD post HSCT was 62 days (IQR = 42 to 151 days). The most common initial site of GvHD was skin (n = 21, 64%), followed by GI tract (n = 10, 30%). Three patients (5%) were diagnosed with vvGvHD. The time of onset of vvGvHD post HSCT ranged from 62 to 1565 days. One patient (33%) was asymptomatic at the time of diagnosis. There was no difference in diagnosis of vvGvHD when race (P = 0.15), age at allogeneic HSCT (P = 0.64), nonmalignant vs malignant indication (P = 0.21), source of stem cells (P = 0.25), partial vs full human leukocyte antigens (HLA) donor match (P = 0.34), and GvHD prophylaxis regimen (P = 0.18) were compared. None had isolated vvGvHD. Vulvovaginal GvHD was preceded by skin GvHD in 1 patient, was preceded by lung GvHD in 1 patient, and occurred concurrently with skin GvHD in the third patient.Pediatric vvGvHD can occur within the first 100 days after transplant and can be asymptomatic. Routine gynecologic evaluation post allogeneic HSCT in children and adolescents should include a thorough review of vulvovaginal symptoms and a gynecologic exam for the detection and treatment of vvGvHD.

Knowledge related to reproductive health in adolescents with sickle cell disease (SCD) is not fully addressed. We evaluated reproductive health and knowledge among adolescent girls with SCD. Seventy-nine adolescents, 13–21 years of age completed a survey on reproductive health and knowledge with menarche age 13.2 (± 1.7) years. Fifty-four percent reported dysmenorrhea and 49% reported SCD pain a week before menstrual cycle. Sixty-two percent reported discussing contraception and pregnancy with medical providers. Adolescents reported late menarche, dysmenorrhea, and pain with menses. Knowledge of overall reproductive health was inadequate. There is an urgent need to improve reproductive education in this population.

Primary amenorrhea may be a feature or a presenting sign of a difference of sex development, most often due to a congenital anatomic difference or hypergonadotropic hypogonadism. History and physical exam are very important, including whether any variation in external genitalia was present at birth as well as a careful review of pubertal development. Further evaluation includes hormone measurement, imaging, and genetic evaluation. Those with a disorder of sexual development diagnosis should receive care through a multidisciplinary team with psychosocial support.

Background The DICER1 mutation is a pathogenic, germline mutation that predisposes patients to uncommon malignancies at a young age. Case A 6-month-old female infant presented with vaginal bleeding and a protruding vaginal mass of unclear pathogenesis. Chemotherapy was initially targeted toward a germ cell tumor; after pathologic testing and auto-amputation of the tumor, the patient was diagnosed with a rare DICER1-associated embryonal rhabdomyosarcoma. Subsequently, her treatment course was restructured and family genetic surveillance instituted. Summary and Conclusion Consideration for DICER1 mutation in tumors with complex pathology and unique presentation is critical to aid in diagnosis and management, and direct future comprehensive surveillance.

Context Anti-Mullerian hormone (AMH) was originally described in the context of sexual differentiation in the male fetus but has gained prominence now as a marker of ovarian reserve and fertility in females. In this mini-review, we offer an updated synopsis on AMH and its clinical utility in pediatric patients. Design and Results A systematic search was undertaken for studies related to the physiology of AMH, normative data, and clinical role in pediatrics. In males, AMH, secreted by Sertoli cells, is found at high levels prenatally and throughout childhood and declines with progression through puberty to overlap with levels in females. Thus, serum AMH has clinical utility as a marker of testicular tissue in males with differences in sexual development and cryptorchidism and in the evaluation of persistent Mullerian duct syndrome. In females, serum AMH has been used as a predictive marker of ovarian reserve and fertility, but prepubertal and adolescent AMH assessments need to be interpreted cautiously. AMH is also a marker of tumor burden, progression, and recurrence in germ cell tumors of the ovary. Conclusions AMH has widespread clinical diagnostic utility in pediatrics but interpretation is often challenging and should be undertaken in the context of not only age and sex but also developmental and pubertal stage of the child. Nonstandardized assays necessitate the need for assay-specific normative data. The recognition of the role of AMH beyond gonadal development and maturation may usher in novel diagnostic and therapeutic applications that would further expand its utility in pediatric care.

Objective To report two cases of mature oocytes found in prepubertal girls undergoing ovarian tissue cryopreservation (OTC). Design Case report. Setting Large tertiary care children’s hospital and a private fertility clinic. Patient(s) An 8-year-old prepubertal girl with β-thalassemia and a 2-year-old girl with sickle cell disease who both underwent OTC before bone marrow transplantations. Intervention(s) Laparoscopic right oophorectomy was performed in each patient. The ovarian cortical tissue was processed for slow freezing and long-term storage, and all oocytes were subsequently vitrified. Main Outcome Measure(s) Oocytes found at the time of OTC processing for fertility preservation. Result(s) After a complete right oophorectomy, one mature metaphase II oocyte was discovered on tissue processing for OTC in each patient. Neither patient has yet returned for use of tissue or oocytes. Conclusion(s) To our knowledge, this is the first report of mature oocytes found during prepubertal OTC processing. These findings may indicate the need for increased research regarding prepubertal oocyte development and suggest that the technique of examining the media for both mature and immature oocytes at the time of OTC should become more widespread and perhaps recommended in prepubertal patients to optimize fertility preservation methods.

The ovaries are the female gonads that are crucial for reproduction, steroid production, and overall health. Historically, the ovary was broadly divided into regions defined as the cortex, medulla, and hilum. This current nomenclature lacks specificity and fails to consider the significant anatomic variations in the ovary. Recent technological advances in imaging modalities and high-resolution omic analyses have brought about the need for revision of the existing definitions, which will facilitate the integration of generated data and enable the characterization of organ subanatomy and function at the cellular level. The creation of these high-resolution multimodal maps of the ovary will enhance collaboration and communication among disciplines and between clinicians and researchers. Beginning in March 2021, the Pediatric and Adolescent Gynecology Program of the Eunice Kennedy Shriver National Institute of Child Health and Human Development invited subject-matter experts to participate in a series of workshops and meetings to standardize ovarian nomenclature and define the organ's features. The goal was to develop a spatially defined and semantically consistent terminology of the ovary to support collaborative, team science-based endeavors aimed at generating reference atlases of the human ovary. The group recommended a standardized, 3-dimensional description of the ovary and an ontological approach to the subanatomy of the ovary and definition of follicles. This new greater precision in nomenclature and mapping will better reflect the ovary's heterogeneous composition and function, support the standardization of tissue collection, facilitate functional analyses, and enable clinical and research collaborations. The conceptualization process and outcomes of the effort, which spanned the better part of 2021 and early 2022, are introduced in this article. The institute and the workshop participants encourage researchers and clinicians to adopt the new systems in their everyday work to advance the overarching goal of improving human reproductive health.

Chimeric antigen receptor (CAR) T-cells serve to overcome chemotherapeutic resistance and have been proven to be highly effective in B-cell hematologic malignancies. Although initial use has been in patients with multiply relapsed/refractory disease, as CAR T-cells are used earlier in the treatment paradigm, it will be important to explore implications of this novel therapy on cancer late-effects. We sought to assess the current framework for considerations of fertility surrounding CAR T-cell use and identify opportunities for education and future research. To assess current practice patterns regarding post-CAR T-cell fertility, peri-CAR T-cell fertility guidance, utilization of fertility preservation surrounding CAR T-cell administration and identify future areas of research, a cross-sectional survey assessing practice patterns regarding fertility counseling and outcomes surrounding CAR T-cell therapy was distributed electronically to approximately 300 Center for International Blood and Marrow Transplant Research medical centers treating patients with CAR T-cell therapy in the United States and internationally between October 12 and November 2, 2021. One medical provider was asked to complete the study survey on behalf of their institution. We received 96 survey responses, of which 66 centers utilized CAR T-cells and provided at least partial responses that were used for the primary analysis. Centers were varied in demographics, experience in administering CAR T-cells, and aspects of patients receiving CAR T-cells. Eighteen centers exclusively treated pediatric patients, and patients at these centers were more likely to be treated for B-cell acute lymphoblastic leukemia. Seven pregnancies and 5 live births after CAR T-cells were reported from 6 centers (1 pediatric-only). Most centers had no established guidelines in place regarding fertility preservation in the peri-CAR T-cell period or regarding recommendations for avoiding pregnancy/fathering a child after receiving CAR T-cells. Areas for future research were elicited from responding centers and categorized into 3 broad themes, including: standardized peri-CAR T-cell fertility guidelines; long-term fertility outcomes after CAR T-cell therapy; impact of CAR T-cells on a developing fetus; and determining the relevance of studying fertility in patients who receive CAR T-cells. We identified a high degree of variability in peri-CAR T-cell guidance on avoidance of pregnancy/fathering a child, as well as a wide-range of practices surrounding referral for fertility preservation, the latter of which may be likely due to the fact that patients receiving CAR T-cells in the present era are likely multiply relapsed/refractory. In summary, this is the first report of several live-births following CAR T-cells, which highlights the important need for further research in CAR T-cell therapy and fertility, with a host of novel research questions identified.

Adnexal torsion is a gynecologic emergency, requiring intervention for tissue preservation. At our institution, torsion is managed by pediatric surgeons or gynecologists. We evaluated differences between specialties to streamline evaluation for children with gynecological emergencies, develop a clinical pathway, and prevent care delays. A retrospective review of adolescents undergoing intervention for adnexal torsion from 2004–2018 was performed. Differences in time to intervention, operation duration, the procedure performed, and length of stay (LOS) between the specialties were analyzed. Eighty-six patients underwent 94 operations for presumed adnexal torsion with 87 positive cases. Pediatric surgeons performed 60 operations and 34 cases were performed by gynecologists. Preservation of fertility was the goal in both cohorts and the rate of oophoropexy, cystectomy, and oophorectomy were similar between the cohorts (p = 0.14, p = 1.0, p = 0.39, respectively). There was no difference in intra-operative time (p = 0.69). LOS was shorter in the gynecology cohort (median 1 day [1–2] vs. 2 days [2–3], p > 0.001). Adnexal torsion is a time-sensitive diagnosis requiring prompt intervention for ovarian or fallopian tube preservation. A multidisciplinary institutional care pathway should be developed and implemented.

Comprehensive care for transgender and gender nonbinary patients has been a priority established by the World Professional Association for Transgender Health. Because pubertal suppression, gender-affirming hormone therapy, and antiandrogen therapy used alone or in combination during medical transition can affect gonadal function, understanding the effects these treatments have on fertility potential is important for practitioners caring for transgender and gender nonbinary patients. In this review, we outline the impacts of gender-affirming treatments on fertility potential and discuss the counseling and the treatment approach for fertility preservation and/or family building in transgender and gender nonbinary individuals.

Impairment of fertility and sexual/reproductive health are common after oncologic therapy, and are known to have negative impacts on romantic relationships and psychosocial well-being among childhood cancer survivors. The Pediatric Initiative Network (PIN) is an international, multidisciplinary group of providers within the Oncofertility Consortium dedicated to preserving and protecting the fertility of children and adolescents at risk for infertility due to medical conditions or treatments. The PIN and its Best Practices and Research committees meet virtually throughout the year, with one annual in-person meeting. The purpose of this “proceedings” is to highlight key discussion points from the annual PIN meeting which took place on November 11, 2019, to 1) provide a context for pediatric groups across the country on what oncofertility programs are currently doing and why, and 2) inform stakeholders of past, present and future initiatives that may be of value to them and the patient populations they serve.

Recently, greater attention has been paid to the care of gender dysphoric and gender incongruent individuals. Gynecologists may be called upon to care for individuals who were assigned female at birth throughout or following social, medical, or surgical gender transition. Thus, gynecologists need to be aware of language regarding sex and gender, treatment typically used for the care of gender dysphoric or incongruent individuals, and aspects of well gynecologic care necessary for these individuals. This review highlights these aspects of care for transgender males to aid the general gynecologist in the care and treatment of these individuals.

A high proportion of observed fetal sex discordances between single-nucleotide polymorphism–based noninvasive prenatal screening tests and prenatal or newborn examinations are attributable to disorders of sexual development., OBJECTIVE: To assess the causes of reported discordance between noninvasive prenatal testing (NIPT) and ultrasound or other clinical information. METHODS: In this retrospective, observational study, all cases in which single-nucleotide polymorphism (SNP)–based NIPT reported normal sex chromosomes and the laboratory was notified by the patient or health care provider of discordance between NIPT and observed or expected fetal sex from clinical information were reviewed. When discordances were unresolved after internal and external laboratory clerical data review or repeat ultrasound imaging, additional clinical records, genetic testing results and pregnancy outcomes were reviewed. RESULTS: Of the 1,301,117 eligible NIPT cases, fetal sex discordances were reported in 91 (0.007%; 1:14,300; 95% CI 1:11,600–1:17,800); partial or complete outcome information was available for 83 of 91 cases. In 30 of 83 (36%) cases, karyotyping was performed, and sufficient clinical information was provided to establish the diagnosis of disorders of sexual development. The disorders of sexual development were classified into three categories: 46,XY disorders of sexual development (n=19), 46,XX disorders of sexual development (n=4), and sex chromosome disorders of sexual development (n=7). In 28 of 83 (34%) cases, the cause of the apparent discrepancy was attributable to human error, predominantly phlebotomy labeling or ultrasound misassignment. In 25 of 83 cases, a diagnosis was not possible; the outcome reported was either abnormal (18/83, 22%) or no abnormalities were reported (7/83, 8%). When normal sex chromosomes were predicted by SNP-based NIPT and clinical information was discordant, disorders of sexual development were common. Internal laboratory clerical data review and re-imaging confirmed the NIPT fetal sex reports in 34% cases, providing reassurance that no further evaluation was necessary. CONCLUSION: Identification of apparent fetal sex discordances with NIPT results, and reporting this suspicion to the laboratory, provides an opportunity for further evaluation to identify the cause of apparent discordances and the involvement of a multi-disciplinary team, as necessary to prepare for postnatal care. We propose a protocol for evaluation of these cases. FUNDING SOURCE: This study was funded by Natera, Inc.

PURPOSE: To describe the development, design, and implementation of a 3D printed MR-compatible pediatric vaginal multichannel brachytherapy cylinder. Safety and quality measures to ensure consistent treatment required innovative identification on MR and CT, and real-time tracking. METHODS AND MATERIALS: A 4-year-old with vaginal botryoides rhabdomyosarcoma underwent MR-simulation with a custom 3D printed biocompatible resin cylinder with four channels to ensure dose optimization capability. A total of four identifier regions were designed into the applicator in order to utilize these for MR-visualization and real-time tracking. A biocompatible 3D printed cylinder was designed to meet dose objectives using an MR and CT compatible material. 3D slicer was required for real-time tracking during treatment. RESULTS: Based on MR simulation, a treatment plan was created with dose differentials in the area of prior surgery versus normal vaginal tissue. Creation of a low dose CT scan on a mobile CT allowed CT visualization of the applicator for verification. Treatment was administered under the use of a real-time optical tracking with rotational and depth adjustments monitored. CONCLUSIONS: This advanced integration of 3D printed MR and CT biocompatible material, with unique design features consistent with a multi-channel vaginal cylinder, and incorporation of real-time optical tracking ensured that no positional changes were required, allowed successful treatment with differential dosing for a post -operative pediatric vaginal rhabdomyosarcoma patient.

Internationally, increasing numbers of children and adolescents with gender dysphoria are presenting for care. In response, gender-affirming therapeutic interventions that seek to align bodily characteristics with an individual's gender identity are more commonly being used. Depending on a young person's circumstances and goals, hormonal interventions may aim to achieve full pubertal suppression, modulation of endogenous pubertal sex hormone effects, and/or development of secondary sex characteristics congruent with their affirmed gender. This is a relatively novel therapeutic area and, although short-term outcomes are encouraging, longer term data from prospective longitudinal adolescent cohorts are still lacking, which may create clinical and ethical decision-making challenges. Here, we review current treatment options, reported outcomes, and clinical challenges in the pharmacological management of trans and gender-diverse adolescents.

Infertility is common among individuals with differences in sex development (DSD), and affected individuals and families desire fertility counseling. This survey sought to assess fertility knowledge and experiences with fertility counseling among DSD specialists for DSD conditions excluding congenital adrenal hyperplasia.A survey was iteratively developed by members of the DSD-Translational Research Network (DSD-TRN) Fertility Preservation Workgroup and disseminated to 5 clinician groups: the DSD-TRN, the Society for Pediatric Psychology DSD Special Interest Group (SIG), the Pediatric Endocrine Society DSD-SIG, the Societies for Pediatric Urology, and the North American Society for Pediatric and Adolescent Gynecology.Completed surveys (n = 110) were mostly from pediatric urology (40.3%), gynecology (25.4%), and endocrinology (20.9%) specialists. Most (73/108, 67.6%) respondents reported discussing fertility potential. Sixty-seven responded to questions regarding fertility potential. Many participants answered questions about the presence of a uterus in individuals with 46,XY complete gonadal dysgenesis and about the potential for viable oocytes in individuals with 46,XY partial gonadal dysgenesis incorrectly. Comments acknowledged the need for further education on fertility in individuals with DSD.Many DSD providers have some knowledge of fertility potential, but knowledge gaps remain. Experts expressed a desire for education and accessible resources to counsel effectively about fertility potential for individuals with DSD.
