The main object of this study was to determine the frequency of occupational categories of men who attended an...

BACKGROUND Although the effect of maternal age on fertility is well known, it is unclear whether paternal age also affects fertility. This cross-sectional study sought to characterize the association between age and semen quality, a well-known proxy of fertility status. METHODS A convenience sample of 97 non-smoking men (aged 22-80 years) without known fertility problems was recruited from a ...

Many antimalarial remedies are known for reproductive toxicity in male. Also, several plants to have antifertility action both sexes. The aim of this study is evaluate the effect ethanol extract Senna occidentalis (L.) Link Leguminosae leaf (EESO) on male parameters such as sperm count, motility, morphology and histology testes Wistar rats by employing standard procedures. (50% ethanol) was ora...

Background: Varicocele occurs in approximately 15 to 20% of the general male population and it is the most common cause of poor semen production and decreased semen quality. Clinical studies have show that varicocele surgery can improve semen quality. The aim of this study was to evaluate if antioxidant therapy adds any extra benefit to standard inguinal varicocelectomy in improvement of sperm ...

Background: Obesity and raised body mass index (BMI) is a major risk factor for several diseases such as cardiovascular disease, type 2 diabetes, as well as gynecological problems. In recent years, some studies have associated the BMI with reproductive parameters in men, showing that increased BMI is related to poor semen quality, decreased sperm concentration, decreased and normal-motile sperm...

background: anti-sperm antibody (asa) can decrease sperm motility and, therefore, it is a cause of male infertility. the aim of this study was to evaluate the effects of varicocelectomy on anti-sperm antibody in patients with varicocele. methods: this observational study was conducted on 90 patients with varicocele at sina and imam khomeini hospitals during 2006 to 2009. all varicocelectomy can...

Effect of a combination of pesticides, viz. Delatmethrin 1% + Chlorpyriphos 35% EC, has been studied on the reproductive toxicology of wistar rats. Male rats were exposed to test substance at the dose level of 15, 25, and 35-mg/kg body weight for a consecutive period of 20 weeks. At the end of the experimental period, all the animals were subjected for necropsy, sperm parameters such as motilit...

this study was designed to clarify bilaterally effect of long-time varicocele on left and right testes and to identify the effect of varicocele on maturation divisions during spermatogenesis. moreover, the percentage of seminiferous tubules (sts) with i-viii and ix-xiv stages of spermatogenesis and sperm parameters such as sperm motility and abnormality types were evaluated. the left varicocele...

conclusions our findings indicated that oxidative stress could play an essential role in male infertility caused by varicocele and may impair spermatogenesis leading to infertility. objectives in the current study, we aimed to assess the tac (total antioxidant capacity) and mda (malondialdehyde) as stress oxidative markers in infertile men with varicocele and fertile men, and moreover, their co...
