TL;DR: Decreased general health status appears to be associated with impaired male reproductive health, including lower sperm concentration, lower total testosterone levels, and higher follicle-stimulating hormone values.

TL;DR: The DNA of herpes viruses is frequently detected in the semen of asymptomatic fertile and infertile male patients and a statistical significance between leukocytospermia and the presence of EBV DNA was observed.

TL;DR: When the characterization of infertility was refined using individual semen parameters, it was found that oligozoospermic men had an increased risk of cancer compared with fertile control subjects, and an association between azoospermia and increased cancer risk was found.

TL;DR: Lipid peroxidation has a deleterious effect on the semen quality and MDA is an index of lipidperoxidation which may be a diagnostic tool for the analysis of infertility in the asthenozoospermic patients.

TL;DR: It is concluded that varicocele is a significant risk factor that negatively affects semen quality, but the observed pooled effect size on semen parameters does not seem to be affected by the WHO laboratory manual edition.
Abstract: This study investigated the effects of varicocele on semen parameters in infertile men based on the new 2010 World Health Organization laboratory manual for the examination of human semen. Semen analysis results (volume, sperm count, motility, and morphology) were the primary outcomes. An electronic search to collect the data was conducted using the Medline/PubMed, SJU discover, and Google Scholar databases. We searched articles published from 2010 to August 2015, i.e., after the publication of the 2010 WHO manual. We included only those studies that reported the actual semen parameters of adult infertile men diagnosed with clinical varicocele and contained a control group of either fertile men or normozoospermic men who were not diagnosed with varicocele. Ten studies were included in the meta-analysis, involving 1232 men. Varicocele was associated with reduced sperm count (mean difference: −44.48 × 10 [6] ml−1 ; 95% CI: −61.45, −27.51 × 10 [6] ml−1 ; P
