background: the trace element copper has been identified as a highly toxic element for sperm. it is known to affect sperm motility in humans and experimental implantation of copper in the epididymis vas deferens and scrotum of mammals has been demonstrated to affect fertility detrimentally. objective: sperm concentration motility vitality and morphology are parameters used to evaluate potential...

PURPOSE To determine whether patients with male factor infertility can be accurately identified by calculating a novel semen quality score and measuring levels of reactive oxygen species during routine infertility screening. METHODS Semen samples from 133 patients and 91 healthy donors were evaluated with manual and computer-assisted semen analysis. A principal component analysis model was em...

BACKGROUND It has been proved that human voltage-dependent anion channel 2 (VDAC2) plays a significant role in sperm function and male fertility. This study was primarily aimed at exploring whether VDAC2 is a risk factor for idiopathic male infertility. RESULTS We determined a significantly increased risk of idiopathic infertility with abnormal semen parameters in association with the variant...

The clinical definition of male infertility is the presence of abnormal semen parameters in the male partner of a couple who have been unable to conceive after 1 year of unprotected intercourse (Dohle 2010). The World Health Organization defines male factor infertility as the presence of one or more abnormalities in the semen analysis, or the presence of inadequate sexual or ejaculatory functio...

In more than half of infertile men, the cause of their infertility is unknown. Several studies revealed the role of viral infections in male infertility. The aim of the present study was to determine the prevalence of herpes simplex virus-1 (HSV-1) and HSV-2 in semen from asymptomatic infertile male patients, and its association with altered semen parameters. A total of 70 semen samples were co...

Although abnormal semen parameters are generally considered to be poor predictors of fertility, Semen Analysis (SA) parameters are often used as a screening test to detect male factor infertility. Certainly, men with azoospermia or severe oligozoospermia have markedly impaired fertility potential [1-3]. Since men with abnormal fertility could undergo various medical or surgical treatments to im...

Background. Infertility is both a clinical and a public problem, affecting the life of the couple, the healthcare services, and social environment. Standard semen analysis is the surrogate measure of male fertility in clinical practice. Objective. To provide information about the relationship between semen parameters and spontaneous conception. Methods. We evaluated retrospectively 453 pregnanc...

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€...

BACKGROUND Infertility is a public health disorder affecting 10% of the population worldwide. Research on the impact of body mass index (BMI) on male fertility is very limited as compared to the multiple studies evaluating the impact of overweight in women's fertility. Although 25%-30% of the cases of couples consulting for infertility are attributable to male factors, studies evaluating the as...

OBJECTIVE To determine the prevalence of herpes viruses in the semen of an asymptomatic male cohort with and without infertility problems and its association with altered semen parameters. DESIGN A prospective randomized study. SETTING Medical school and IVF clinic. PATIENT(S) One hundred seventy-two male patients undergoing routine semen analysis: 80 with normal semen parameters (control...
