context air pollution is common in all countries and affects reproductive functions in men and women. it particularly impacts sperm parameters in men. this meta-analysis aimed to examine the impact of air pollution on the quality of sperm. conclusions the results of this meta-analysis showed that air pollution reduces sperm motility, but has no impact on the other sperm parameters of spermogram...

introduction: varicocele is considered as a common cause of male infertility. the aim of this study was to evaluate the effects of varicocelectomy on sperm parameters, sperm membrane integrity and sperm nuclear maturity. materials and methods: in this study along with routine semen analysis, hypo-osmotic swelling test (host), and aniline blue staining for assessment of as 45 and 90 days after i...

abstract background: sperm cells extracted from testes (tese) have poor chromatin quality and motility. various substances are used in the laboratory to increase sperm motility and improve the art outcomes; however, there are few research which considered improving both sperm motility and chromatin quality. objective: the aim of this investigation was to evaluate the improvement of the testicul...

conclusions our study showed that ultrasonography findings can be a good predictor of sperm parameters in patients with varicocele. results the semen analysis parameters, including semen volume and sperm morphology, count, and motility, significant correlations with the diameter of the varicocele vein but were not correlated with testes size. in addition, the patients with reflux of longer than...

This work evaluates sperm head morphometric characteristics in adolescents from 12 to 18 years of age, and the effect of varicocele. Volunteers between 150 and 224 months of age (mean 191, n = 87), who had reached oigarche by 12 years old, were recruited in the area of Barranquilla, Colombia. Morphometric analysis of sperm heads was performed with principal component (PC) and discriminant analy...

we examined the demographic characteristics of couples, ovarian response and sperm quality to determine the predictors of clinical fertilization in ivf cycles. a descriptive and analytic study was conducted using data and biologic specimens obtained fatemeh-alzahra of babol infertility center from 2004 to 2005. only data from 315 women who had medical indication for conventional ivf treatment w...

background: recently, motile sperm organelle morphology examination (msome) criteria as a new real time tool for evaluation of spermatozoa in intracytoplasmic sperm injection (icsi) cycles has been considered. objective: the aim was to investigate the predictive value of msome in in vitro fertilization (ivf) in comparison to icsi cycles and evaluation of the association between msome parameters...

The 5th edition of WHO Laboratory Manual for the Examination and Processing of Human Semen (2010) represents a comprehensive revision. This article aims to explore the applicability of this manual to andrology laboratories in China mainland in view of sperm count analysis, sperm motility analysis, sperm morphology analysis, sperm function analysis, anti-sperm antibody and seminal plasma biochem...

background: high level of semen reactive oxygen species is considered as an important factor in male infertility. sesame has antioxidant properties, which could be effective on improvement of semen parameters. this study was designed to determine the effects of sesame on sperm quality.   materials and methods: twenty‑five infertile men entered this clinical trial. they were treated with a 3â€...

The development of male infertility increased rapidly worldwide, which coinciding with the epidemic of obesity. However, the impact of weight abnormalities on sperm quality is still contestable. To assess the correlation between BMI and sperm parameters, we searched relevant articles in PubMed, Embase, Web of science, and Wanfang database published until June 2015 without language restriction. ...
