The present study assessed the effects of daily supplementation with 33 mg/metabolic weight (MW) of γ-oryzanol on testicular degeneration induced by scrotal insulation in rams. Eight animals were divided into two groups: Control (subjected to scrotal insulation without treatment) and Gamma (subjected to scrotal insulation and γ-oryzanol treatment). The rams were subjected to scrotal insulation by covering the scrotum with a thermal bag for 72 h. Animals in the Gamma group received 33 mg/MW oral γ-oryzanol once-daily, beginning 7 days before insulation and continuing during insulation and for 20 days afterward, for a total treatment period of 30 days...

Heitor O Santos, Filipe J Teixeira
Hypogonadism affects an extensive part of the male population, especially among the elderly. The quest for treatment regarding low levels of serum testosterone and male infertility has, therefore, worldwide relevance. Zinc has important biological actions insofar as the male reproductive physiology and endocrine system. In general, a common and safe recommendation for zinc in the treatment of male hypogonadism is 220 mg of zinc sulfate (equivalent to 50 mg of elemental zinc) twice a day, over one to four months...

Vitamin D3 and its receptor are responsible for controlling energy expenditure in adipocytes and have direct roles in the transcriptional regulation of energy metabolic pathways. This phenomenon also has a significant impact on the etiology of prostate cancer (PCa). Using several in vitro models, the roles of vitamin D3 on energy metabolism and its implication in primary, early and late invasive PCa was investigated. BODIPY staining and qPCR analyses show that 1,25-dihydroxyvitamin D3 (1,25(OH)2 D3 ) up-regulates de novo lipogenesis in PCa cells by orchestrating transcriptional regulation that affects cholesterol and lipid metabolic pathways...

Polycystic ovary syndrome (PCOS) increases the risk of metabolic syndrome and non-alcoholic-fatty-liver disease (NAFLD). Vitamin D supplementation may exert positive effects on liver biochemistry in patients with NAFLD; however, its effects on PCOS are unknown. This randomized, double-blind, placebo-controlled study explored the effect of vitamin D supplementation on cardiovascular risk factors (high-sensitivity C-reactive protein ( hs -CRP), weight, body mass index (BMI), lipid profile, glucose levels, insulin levels, the homeostatic model assessment-insulin resistance (HOMA-IR), hormones (free androgen index (FAI), testosterone, sex hormone binding globulin (SHBG), and liver markers (alanine aminotransferase (ALT), hyaluronic acid (HA), N-terminal pro-peptide of type III procollagen (PIIINP), tissue inhibitor of metallo-proteinases-1 (TIMP-1), and the enhanced liver fibrosis (ELF) score)...

Granulosa cell (GC) proliferation is essential for follicular development. FSH is a key factor in GC proliferation, and a continuous supply of high levels of ATP is necessary for cell proliferation. However, genes encoding proteins of the glycolytic pathways are poorly expressed in GCs. Therefore, we hypothesized that mitochondrial gene expression and protein synthesis play a primary role in ATP production during GC proliferation. To test this hypothesis, we performed an in vivo study of GCs collected from 23-day-old mice ovaries with or without equine chorionic gonadotropin (eCG) priming...

Metformin (MET), the most commonly used insulin sensitizer, is the reference off-label drug for the treatment of polycystic ovary syndrome (PCOS), worldwide. However, its use may be limited mainly by gastrointestinal adverse effects. Myo-inositol (MI), a well-recognized food supplement, also represents an evidence-based treatment for PCOS women, popular in many countries. Our aim is to provide a systematic review of the literature and a meta-analysis which compares these two treatments, for their short-term efficacy and safety in PCOS patients...

Gonadotropin therapy is commonly used to induce virilization and spermatogenesis in male isolated hypogonadotropic hypogonadism (IHH) patients. In clinical practice, 5.6%-15.0% of male IHH patients show poor responses to gonadotropin treatment; therefore, testosterone (T) supplementation can serve as an alternative therapy to normalize serum T levels and promote virilization. However, treatment with exogenous T impairs spermatogenesis and suppresses intratesticular T levels. This retrospective study aimed to determine whether oral testosterone undecanoate (TU) supplementation together with human chorionic gonadotropin (hCG) would negatively affect spermatogenesis in IHH patients compared with hCG alone...

Loss of skeletal muscle mass and strength is often associated with disability and poor quality of life. Selective Androgen Receptor Modulators (SARMs) are under development as potential treatment. This study aims at examining the potential of wild bitter gourd (BG) as a SARM and its effects on the muscle decline induced by orchiectomy. In the cell-based androgen receptor (AR) transactivation assay, the BGP extract showed weak agonistic and antagonistic activities, resembling those of some SARMs. Male C57BL/6J mice were sham-operated (Sham group) or castrated (Cast groups) and fed a modified AIN-93G high sucrose diet supplemented without (Cast group) or with 5% lyophilized BG powder (Cast + BGP) or with testosterone propionate (7 mg TP per kg diet, Cast + TP) for 23 weeks...
