We aimed to investigate the role of thioredoxin reductase (TR) and inducible heat shock protein 70 (iHsp70) and their relationship with sperm quality in varicocele (VAR) patients. Semen samples were obtained from 16 subfertile men diagnosed as VAR and 10 fertile men who applied to the Andrology Laboratory of Istanbul Medical Faculty of Istanbul University. The sperm TR and iHsp 70 expression le...
OBJECTIVE To compare the sperm chromatin dispersion (SCD) test and the terminal uridine nick-end labeling (TUNEL) assay for assessment of sperm DNA damage. DESIGN Prospective comparative experimental study. SETTING Andrology laboratory. PATIENT(S) Twenty subfertile men with unexplained infertility. INTERVENTION(S) Sperm DNA damage was determined in the same semen samples using the TUNEL...
Varicocele is the most common cause of male infertility and is generally correctable or at least improvable by various surgical and radiologic techniques. Therefore, it seems simple and reasonable that varicocele should be treated in infertile men with varicocele. However, the role of varicocele repair for the treatment of subfertile men has been questioned during the past decades. Although var...
BACKGROUND An association between male fertility and risk of prostate cancer has been suggested, possibly through lower androgen levels in subfertile men. We evaluated male fertility in relation to risk of prostate cancer by assessing the frequency of fathering of dizygotic twins, a marker of high fertility, among cases of prostate cancer and controls. METHODS We performed a case-control stud...
BACKGROUND Present knowledge on the impact of varicoceles on testicular function is largely based on studies of subfertile and infertile men, making it difficult to extrapolate the impact of varicocele on the general population. OBJECTIVE To describe associations between varicocele and testicular function assessed by semen analysis and reproductive hormones in men from the general population....
HIRSCH IH. Optimizing fertility potential in spinal cord injured men. Can J Urol 2012;19(5):6437. even after spinal cord injury. As the hurdle of semen retrieval has been successfully transcended in over 90% of such men, our research objectives should be directed toward the optimization of semen quality associated with neurogenic infertility. Over the past 3 decades significant therapeutic inro...
