background: infections are one of the correctable causes of infertility with low cost and cost effective treatment. the 50% of infertile cases is related to men in some way, and 30% of them are absolutely related to them. mycoplasmas are the smallest microorganisms with capability of dna replication. present study is planned to compare the mycoplasma infection in infertile men and men with esta...

background: phospholipids are distributed asymmetrically between inner and outer leaflets of the plasma membrane of live cells. early during apoptosis, this asymmetry is disrupted and phosphatidylserine becomes exposed on the outside surface of the plasma membrane. there is little information about the effects of vitrification on apoptosis. objective: the aim of the present study was to evaluat...

OBJECTIVE To assess semen analysis, testicular volume, and hormone levels in fertile and infertile patients with varicoceles and fertile men without varicoceles. DESIGN Retrospective study. SETTING Academic medical center. PATIENT(S) Patients were divided into three groups: fertile men with varicoceles (n = 79), infertile men with varicoceles (n = 71), and fertile men without varicoceles ...

objective: to compare resilience, positive/negative effect, and psychological vulnerability between fertile and infertile men. methods: the research sample consisted of 40 fertile and 40 infertile men who were selected among men who presented to an infertility clinic. to collect data, connor–davidson resilience scale, positive/negative affect schedule, and brief symptoms inventory were used. re...

OBJECTIVE To investigate: 1) the impact of clinical varicocele on reactive oxygen species (ROS) levels in neat and washed semen in a proven fertile population; and 2) the correlation between ROS levels, testicular volume, and varicocele grade in the same population of fertile men. DESIGN Prospective controlled clinical study. SETTING Andrology laboratory at tertiary-care hospital. PATIENT...

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...

BACKGROUND A number of studies have indicated regional differences in semen quality. To examine the current status in Japan, we undertook a cross-sectional study on the semen quality of fertile Japanese men for comparison with recent European results. METHODS Semen parameters of 324 fertile men from the Kawasaki/Yokohama area were investigated. The semen parameters were compared with those pu...

OBJECTIVE To compare semen quality and levels of seminal oxidative stress among three groups: infertile men with varicocele, fertile men with varicocele, and healthy semen donors (controls) without varicocele. DESIGN Prospective study. SETTING Academic medical centers. INTERVENTION(S) None. PATIENT(S) Semen specimens were obtained from 21 infertile patients with varicocele, 15 fertile m...

OBJECTIVE To assess the effect of smoking on sperm vitality, sperm DNA integrity, semen reactive oxygen species, and zinc levels in fertile men. METHODS One-hundred sixty men were investigated. They were divided into 2 equal groups: healthy fertile nonsmokers and healthy fertile smokers. They were subjected to history taking, clinical examination, and semen analysis. In their semen, sperm hyp...

BACKGROUND To examine human microRNA expression in fertile men and subsequently to compare expression patterns of miRNAs in fertile and infertile men, specifically men with Sertoli Cell Only (SCO) histopathology. METHODS Testicular tissues from men with azoospermia and SCO, as well as those of men with normal spermatogenesis, were analyzed. MicroRNA was isolated using the miRCURY™ RNA Purific...
