OBJECTIVE This study evaluated the integrity of the chromatin structure, reactive oxygen species (ROS) levels, mitochondrial membrane potential (MMP), DNA damage and lipid peroxidation of semen samples from infertile men classified as unexplained infertility. METHODS Between February 2010 and July 2011 semen parameters and functional tests were evaluated(More)
Male infertility can be responsible for up to 20% of the cases attending fertility consultation facilities; nonetheless, the underlying molecular mechanisms that could explain it are still elusive. Therefore, we aimed to evaluate conventional and functional parameters of semen samples from patients who presented with male infertility of unknown origin.(More)
BACKGROUND Several factors have been shown to influence semen parameters, one of which is sexual abstinence; a clinical criteria included in the semen evaluation to provide maximum sperm quality. The aim of the present study was to assess the effect of a daily ejaculation frequency on conventional and functional semen parameters. METHODS Semen samples(More)
M ean total IPSS had increased in men of the placebo group by 1.35 points, whereas it had decreased in men with dutasteride by 0.46; a statistically significant change between the two groups was calculated from month 6 until the end of the trial ( p < 0.01). For thosemenwith an IPSS <8 at baseline, IPSS increased over 4 yr both in the placebo (1947 men; +3(More)
selected patientswith iSRMs [5]. Ideal candidates for surveillance are those with iSRMs who have benign or papillary/ chromophone RCC histology or those with low-grade clear cell RCC and life expectancy <10 yr. Accuracy of pathologic findings from renal mass biopsy will help urologists address less aggressive treatment options, including surveillance(More)
Background The quality of semen depends upon several factors such as environment, life style, physical activity, age, and occupation. The aim of this study was to analyze and compare the conventional and functional semen parameters in men practicing vigorous physical activity to those of sedentary men.
