The study investigated the comparative influence of different extraction solvents on spermiogram, hormonal profiles and antioxidant activities in rabbit bucks. Adult New Zealand White rabbit bucks (n=18), with average live weight of 1.2±0.03 kg and aged 10-18 mo were fed ad libitum on a commercial diet. They were administered five different Azanza garckeana (AG) fruit pulp extracts at 500 mg/kg via oral gavage, comprising control group (Con), crude (AG Cr), methanol (AG M), n-hexane (AG H), ethyl acetate (AG E) and aqueous (AG AQ) for four weeks. The extracts improved the spermiogram in rabbit bucks administered methanol (AG M) and the reaction time was significantly (P

The study investigated the comparative influence of different extraction solvents on spermiogram, hormonal profiles and antioxidant activities in rabbit bucks. Adult New Zealand White rabbit bucks (n=18), with average live weight of 1.2±0.03 kg and aged 10-18 mo were fed ad libitum on a commercial diet. They were administered five different Azanza garckeana (AG) fruit pulp extracts at 500 mg/kg via oral gavage, comprising control group (Con), crude (AG Cr), methanol (AG M), n-hexane (AG H), ethyl acetate (AG E) and aqueous (AG AQ) for four weeks. The extracts improved the spermiogram in rabbit bucks administered methanol (AG M) and the reaction time was significantly (P<0.05) lower in AG E group when compared to other groups. The ejaculate volume, sperm motility, pH and sperm concentration were significantly (P<0.05) higher in the AG M group when compared to the other groups. There was a significant (P<0.05) increase in concentrations of blood testosterone, follicle-stimulating hormone and luteinising hormone in methanol extract group (AG M). While the glutathione and malondialdehyde concentrations were (P<0.05) lower, catalase and superoxide dismutase activities were significantly (P<0.05) higher in the groups administered methanol extract (AG M). It was concluded that AG M extracts of AG pulp elicited the best response in spermiogram, hormonal concentrations and antioxidant activities in New Zealand White rabbit bucks. Its use as the extraction solvent is recommended. [ABSTRACT FROM AUTHOR]

Background The most prevalent endocrine condition affecting women of reproductive age is polycystic ovarian syndrome (PCOS), which is linked to a variety of metabolic abnormalities. Although the pathogenesis of PCOS is not fully understood, it is known that oxidative stress, altered gut microbiome, and increased gonadotrophin-releasing hormone play a significant role. Gum arabic (GA) is an edible, dried, gummy exudate from the Acacia senegal tree, well-known for its prebiotic and antioxidant effects. The main objective of the study was to assess the changes in hormonal and metabolic profiles in PCOS patients after the ingestion of gum arabic. Method This was a clinical trial conducted on fifteen patients suffering from PCOS, with a mean age of 27.8 years (20-39 years). All patients experienced irregular cycles. Hormonal and metabolic markers (follicular stimulating hormone (FSH), luteinizing hormone (LH), total testosterone (TT), fasting insulin, total cholesterol (TC), and glycosylated hemoglobin (HBA1c) were measured before and after the ingestion of gum arabic (30 g/day of GA dissolved in 250 ml water for eight weeks) on the second day of the menstrual cycle after granting ethical approval from the National Medicine and Poisons Board and from the participants of the study. Results The study demonstrated a significant decrease in the luteinizing hormone level, FSH/LH ratio, and cholesterol pre- and post-gum arabic ingestion (p-values 0.001, 0.013, and 0.007, respectively). Follicular stimulating hormone slightly reduced post-ingestion with no significant difference (p-value 0.414). No significant changes were seen in the testosterone, insulin, or HBA1c levels. Conclusion The study concluded that gum arabic ingestion for eight weeks decreases the luteinizing hormone and LH/FSH ratio and improves the metabolic profile by reducing the cholesterol level in PCOS patients., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Mohamed et al.)

Background: To the best of our knowledge, data on effects of probiotic administration on hormonal profiles, biomarkers of inflammation and oxidative stress in women with polycystic ovary syndrome (PCOS) are scarce. This investigation was conducted to assess the effects of probiotic supplementation on hormonal profiles, biomarkers of inflammation and oxidative stress in women with PCOS. Methods: This randomized, double-blind, placebo-controlled trial was conducted on 60 women with PCOS, aged 18-40 years old. Subjects were randomly assigned into 2 groups to receive either probiotics or placebo (n = 30 each group) for 12 weeks. Metabolic profiles were quantified at baseline and after a 12-week intervention. Results: After the 12-week intervention, compared with placebo, probiotic supplementation significantly increased serum sex hormone-binding globulin (SHBG) (+25.9 ± 32.5 vs. +0.5 ± 15.6 nmol/L, P < 0.001) and plasma total antioxidant capacity (TAC) (+8.8 ± 120.5 vs. -98.3 ± 246.4 mmol/L, P = 0.04), and significantly decreased serum total testosterone (-0.2 ± 0.7 vs. +0.2 ± 0.6 ng/mL, P = 0.03), modified Ferriman-Gallwey (mF-G) scores (-1.7 ± 1.5 vs. -0.2 ± 1.0, P < 0.001), serum high-sensitivity C-reactive protein (hs-CRP) (-1150.0 ± 1295.2 vs. +202.5 ± 1426.3 ng/mL, P < 0.001) and plasma malondialdehyde (MDA) concentrations (-0.2 ± 0.6 vs. +0.9 ± 1.3 µmol/L, P < 0.001). We did not observe any detrimental effect of probiotic supplementation on other metabolic profiles. Conclusion: Overall, probiotic supplementation of PCOS women for 12 weeks had beneficial effects on total testosterone, SHBG, mFG scores, hs-CRP, TAC and MDA levels but did not affect other metabolic profiles.

This study was carried out to evaluate the effects of vitamin D supplementation on the metabolic profiles of insulin-resistant subjects with polycystic ovary syndrome (PCOS). This randomized double-blind, placebo-controlled trial was conducted on 90 insulin-resistant women with PCOS. Participants were randomly assigned to three groups to intake either 4000 IU of vitamin D or 1000 IU of vitamin D or placebo (n = 30 each group) daily for 12 weeks. Vitamin D supplementation (4000 IU), compared with vitamin D (1000 IU) and placebo, led to significant reductions in total testosterone (-0.2 ± 0.2 vs. -0.1 ± 0.6 and +0.1 ± 0.2 ng/mL, respectively, p = 0.02), free androgen index (FAI) (-0.06 ± 0.12 vs. -0.02 ± 0.12 and +0.004 ± 0.04, respectively, p = 0.04), hirsutism (-1.1 ± 1.1 vs. -0.8 ± 1.2 and -0.1 ± 0.4, respectively, p = 0.001) and high-sensitivity C-reactive protein (hs-CRP) (-0.7 ± 1.4 vs. -0.5 ± 0.9 and +0.5 ± 2.4 mg/L, respectively, p = 0.01). In addition, we found significant elevations in mean change of sex hormone-binding globulin (SHBG) (+19.1 ± 23.0 vs. +4.5 ± 11.0 and +0.7 ± 10.4 nmol/L, respectively, p < 0.001) and total antioxidant capacity (TAC) (+130 ± 144 vs. +33 ± 126 and -36 ± 104 mmol/L, respectively, p < 0.001) in the high-dose vitamin D group compared with low-dose vitamin D and placebo groups. Overall, high-dose vitamin D administration for 12 weeks to insulin-resistant women with PCOS had beneficial effects on total testosterone, SHBG, FAI, serum hs-CRP and plasma TAC levels compared with low-dose vitamin D and placebo groups.

An on-farm lactation trial of 4 months duration was conducted to study the effect of feeding strategic limiting nutrient supplements on milk production performance and hormonal profile of crossbred cows under field condition. Crossbred cows (36) were equally divided into 6 groups (control and experimental) based on lactation number, milk yield and stage of lactation. Strategic nutrient supplements (1, 2, 3, 4 and 5) were prepared with 65% of locally available bypass rich protein/amino acid supplements and 30% of the bypass fat and 5% of area specific mineral mixture (ASMM), respectively in all the supplements. Protected soybean extraction (0.9% formaldehyde treated; PS) was added as a source of bypass rich protein/amino acid supplement in supplement 1, PS and maize gluten meal (MGM) (60: 40) in supplement 2, cottonseed cake (CSC) and MGM (60:40) in supplement 3, PS, MGM and CSC (70:15:15) in supplement 4 and PS, MGM and CSC (40:40: 20) in supplement 5. The cows in control group were fed local mixed grass with supplements such as groundnut cake (GNC) and wheat bran as practiced by the farmers. Animals in experimental groups (G 1, 2, 3, 4 and 5) were fed local mixed grass with GNC, wheat bran and supplements 1, 2, 3, 4 and 5, respectively @ 200g/day/animal by replacing the double the quantity of GNC in the experimental groups. There was an increase of 16, 14, 9, 10 and 2 % in 4% fat-corrected milk (FCM) yield in animals fed with limiting nutrient supplements 1, 2, 3, 4 and 5, respectively when compared to control. Plasma hormonal profiles of growth hormone, insulin like growth factor 1, estradiol-17β, progesterone, triiodothyronine and thyroxine hormone were positively correlated (r=0.69; P<0.05) with milk yield in cows fed with strategic nutrient supplements (SNS). The study showed that feeding of supplements 1 and 2 in experimental groups-1 and 2 significantly (P<0.05) increased FCM yield and reduced the feed cost in medium yielding cows on local mixed grass based diets and increased the overall income of the farmers.

This study was carried out to evaluate the effects of vitamin D supplementation on the metabolic profiles of insulin-resistant subjects with polycystic ovary syndrome (PCOS). This randomized double-blind, placebo-controlled trial was conducted on 90 insulin-resistant women with PCOS. Participants were randomly assigned to three groups to intake either 4000 IU of vitamin D or 1000 IU of vitamin D or placebo (n = 30 each group) daily for 12 weeks. Vitamin D supplementation (4000 IU), compared with vitamin D (1000 IU) and placebo, led to significant reductions in total testosterone (−0.2 ± 0.2 vs. −0.1 ± 0.6 and +0.1 ± 0.2 ng/mL, respectively, p = 0.02), free androgen index (FAI) (−0.06 ± 0.12 vs. −0.02 ± 0.12 and +0.004 ± 0.04, respectively, p = 0.04), hirsutism (−1.1 ± 1.1 vs. −0.8 ± 1.2 and −0.1 ± 0.4, respectively, p = 0.001) and high-sensitivity C-reactive protein (hs-CRP) (−0.7 ± 1.4 vs. −0.5 ± 0.9 and +0.5 ± 2.4 mg/L, respectively, p = 0.01). In addition, we found significant elevations in mean change of sex hormone-binding globulin (SHBG) (+19.1 ± 23.0 vs. +4.5 ± 11.0 and +0.7 ± 10.4 nmol/L, respectively, p < 0.001) and total antioxidant capacity (TAC) (+130 ± 144 vs. +33 ± 126 and −36 ± 104 mmol/L, respectively, p < 0.001) in the high-dose vitamin D group compared with low-dose vitamin D and placebo groups. Overall, high-dose vitamin D administration for 12 weeks to insulin-resistant women with PCOS had beneficial effects on total testosterone, SHBG, FAI, serum hs-CRP and plasma TAC levels compared with low-dose vitamin D and placebo groups.

The present study was conducted to find out the effect of supplementing defatted and detoxified neem ( Azadirachta indica ) seed cake as a partial replacement of soybean meal (SBM) in the diet of growing lambs. Male lambs of uniform body weight (8.31 ± 0.32 kg) were randomly allotted to three groups such as control (diet containing SBM) and two test diets with defatted and detoxified neem cake (DNC) at two levels (34 g and 68 g per kg of diet) replacing 25% and 50% nitrogen of SBM (DNC-25 and DNC-50). The respective diets (concentrate mixtures along with finger millet ( Eleucine corocana ) straw) were fed individually to lambs for a period of 140 days. The repeated measure ANOVA indicated that lambs on DNC treatments grew on par with control across all the periods and no interaction was observed. The difference in the dry matter intake was not found to be significant ( P > 0.05) in any of the three study groups. Similarly apparent nutrient digestibility, nitrogen balance, rumen and hormonal profiles did not differ ( P > 0.05) across the groups. Humoral and cell mediated immune response measured in terms of antibody titre and lymphocyte proliferation assay was also the same ( P > 0.05) across the groups. The relative gene expression of IGF-I and LHR transcripts in testes tissue was positively influenced ( P < 0.05) in DNC-50 treatment (3–4 fold increase) as compared to control and DNC-25. No histopathological changes were observed in vital organs of sheep fed DNC diets compared to control. It can be concluded that based on the studied parameters, DNC can replace 50% of SBM nitrogen with 3–4 fold increase in gene expression in testes tissue. [ABSTRACT FROM AUTHOR]

The aim of the study was to identify the changes in estradiol, progesterone, testosterone, luteotropic (LTH), follicle-stimulating (FSH), thyreotropic (TTH) hormones, prolactin, triiodothyronine (T3), and thyroxine (T4) in autonomicdyshormonal myocardiodystrofy (ADM) of various ethiology. Hormone levels were measured in 52 menopausal women with pathological climax, women with uterine fibromyoma (n=45), premenstrual syndrome, PMS (n=36), and with post-castration syndrome (n=42). Mean estradiol level in ADM of various genesis was close to lower norm limit. Estradiol level disturbances were identified in more than 50% of all cases, typically manifesting in lower concentrations. High prevalence of normal estradiol levels in all four groups was an evidence of ADM pathogenesis complexity. Progesterone and testosterone levels were also not significant in ADM development. In uterine myoma and, to a lesser extent, in PMS, increased LTH levels were more prevalent. In PMS and, especially, in uterine myoma, FSH levels were usually elevated. Nevertheless, the role of these disturbances in ADM pathogenesis is still understudied. Mean prolactin level in myoma patients was higher than normal or that in ADM of another genesis. TTG, T3, and T4 levels in all four groups were normal, and couldn't play a significant role in ADM development.
