The deficiency of vitamin D is public among hemodialysis (HD) patients and a key factor in the development secondary hyperparathyroidism (SHPT). Secondary currently accomplished by lowering circulating phosphate levels with parathyroid hormone (PTH), analogs, oral binders. current study aim was to assess efficacy cholecalciferol management concomitant deficiency/insufficiency. A total 53 were t...

levofloxacin is one of the fluroquinoline antibiotic groups, which affect on controlling infections, especially in reproductive organs. it has therapeutic use in numerous countries, but little information exists on the effects of levofloxacin on spermatogenesis when it is used for infectious treatment. the current study was designed to determine whether levofloxacin influences testis tissue and...

OBJECTIVE To assess the risk of development of hormone-related tumors in transsexuals receiving treatment with cross-sex hormones. Design Description of cases of transsexuals who have developed a hormone-related malignancy observed in their own clinic or reported in the literature. Recommendations for early diagnosis and prevention are presented. METHODS Review of the literature in PubMed. ...

AIMS To study the value of assessing serum concentrations of luteinising hormone (LH), follicle stimulating hormone (FSH), testosterone, and dihydrotestosterone (DHT) in patients with male undermasculinisation not caused by androgen insensitivity. METHODS A retrospective study of a register of cases of male undermasculinisation (20 with abnormal testes, eight with 5alpha-reductase deficiency,...

conclusions chronic administration of high doses of nd can alter serum fsh, lh and testosterone and hematological parameters in male rats. results serum testosterone, lh, fsh, weight gain, food and water intake in group t were significantly decreased compared to other groups (p < 0.05). in addition erythrocyte, leucocytes, hemoglobin and hematocrit in group t were significantly increased compar...

BACKGROUND Opioid consumption has been widely increasing across the globe; how- ever, it can cause adverse effects on the body. Morphine, an opioid, can reduce sex hor- mones and fertility. Withania somnifera (WS) is a traditional herb used to improve sexual activities. This study strives to investigate the effect of WS on sex hormones and gonado- tropins in addicted male rats. MATERIALS AND ...

The androgenic gland in malacostracan crustacean species produces and secretes androgenic gland hormone, which is responsible for male sexual differentiation, such as the induction and development of male sexual traits, and in turn the suppression of female sexual traits. Marmorkrebs, Procambarus fallax forma virginalis, which was identified as the first parthenogenetic species in decapod crust...

The sexual reproductive process of Achlya ambisexualis, a heterothallic form belonging to a well known and widely distributed genus of saprophytic aquatic fungi, is initiated and coordinated by means of specific substances (Raper, 1939, a). Four of these substances have been demonstrated (Raper, 1939, b, 1940) in the r&es of initiators and coordinators of the various stages in the sexual proces...

BACKGROUND Nickel exposure is recognized as an endocrine disruptor because of its adverse effects on reproduction. AIM This study was designed to investigate the possible testiculo-hormonal perturbations on workers occupationally exposed to nickel and to assess its effects on human male sexual function. METHODS Cross-sectional comparative study, comprising 105 electroplating male non-smoker...

Commensurate with the decline in many crustacean populations has been an accumulation in reports of sexually ambiguous individuals within these populations. The cause of gynandromorphism or intersex among crustaceans is unknown. We show that gynandromorphism in the branchiopod crustacean Daphnia magna is initiated by the sex-determining hormone methyl farnesoate when levels of the hormone are i...
