INTRODUCTION In our study, we reviewed efficacy and complication rates of open subinguinal varicocelectomy (OSV) and loupe assisted subinguinal varicocelectomy (LASV) using seminal and hormonal parameters in a prospective randomized study. MATERIALS AND METHODS We prospectively studied 60 males with Grade 2 and Grade 3 varicocele. Thirty patients underwent OSV and the other 30 patients underw...

BACKGROUND Sperm dysfunction caused by reactive oxygen species (ROSs) is one of the major causes of infertility in men, which leads to, lipid peroxidation (LPO) and the formation of stable peroxidation products like Malondialdehyde (MDA) in seminal plasma. MDA is effective factor in reducing fertility. OBJECTIVES The aim of this study is to determine two biochemical markers of oxidative stres...

BACKGROUND Diabetes mellitus has a variety of structural and functional effects on the male reproductive system. Diabetes results in reduced sperm parameters and libido. The present study aims to investigate the effects of royal jelly (RJ) on reproductive parameters of testosterone and malondialdehyde (MDA) production in diabetic rats. MATERIALS AND METHODS This experimental study was conduct...

Bisphenol A (BPA) is an estrogenic environmental toxicant, a synthetic monomer widely used to polymerize polycarbonate plastics and resins. BPA has been implicated to have hazardous effect on reproductive health in human and experimental rats. Lycopene is a powerful antioxidant and potential high-value compound for the prevention of many diseases. The present study has been designed to investig...

The present study investigated the impact of zinc oxide nanoparticles (ZnONPs) on the oxidative status and sperm characteristics in diabetic rat testicular tissue. Forty male albino rats were used in this study; 10 of them served as a control and 30 rats were injected with a single dose (100 mg/kg) of streptozotocin intraperitoneally. They were subdivided into diabetic, diabetic + ZnONPs (10 mg...

OBJECTIVE To identify whether the cause, site of ductal obstruction, and characteristics of fluid aspirates are associated with the cryosurvival and fertility after thawing of sperm obtained during reconstruction of the excurrent ducts with microsurgical epididymal sperm aspiration, vasal sperm aspiration, or both. DESIGN Prospective study. SETTING Andrology center at a tertiary care instit...

This study investigated the protective effects of diallyl disulfide (DADS) against cyclophosphamide (CP)-induced testicular toxicity in male rats. DADS was gavaged to rats once daily for 3 days at 100 mg/kg/day. One hour after the final DADS treatment, the rats were given a single intraperitoneal dose of 150 mg/kg CP. All rats were killed and necropsied on day 56 after CP treatment. Parameters ...

background: active immunization against gnrh decreases the secretion of gonadotropins and causes cessation of gonadal function, thereby, inducing infertility. based on the immunoenhancing activity of kamdhenu ark (distilled cow urine), this study was performed to evaluate its effects on the gonadosomatic indices (gsi) and sperm parameters in male mice receiving a gnrh contraceptive vaccine. met...

The protective effect of vitamin E (VE, α-tocopherol) on methyl methanesulfonate (MMS)-induced teratozoospermia was investigated in adult rats. Rats (n=6 per group) were divided into three groups: i) Control group, treated with distilled water from days 1 to 5; ii) the MMS group, treated with MMS at a dose of 40 mg·kg(-1) from days 1‑5; or iii) the VE+MMS group, treated with MMS at a dose of 40...

Arsenic has a suppressive influence on spermatogenesis and induces impairment in male reproductive system due to oxidative stress. The present study was aimed to test the arsenic induced toxicity and protection by Chlorophytum borivilianum. The effect of sodium arsenite (4 mg/(kg body weight (bw) x day)) via double distilled water without or with C. borivilianum (800 mg/(kg bw x day)) was evalu...
