Objective: This study was carried out to determine whether ejaculation may modify the serum prostate-specific antigen (PSA) level and to investigate whether postejaculation serum PSA may play a role in male hypofertility work-up.
Methods: Serum PSA concentration was determined before and 1 h after ejaculation in 18 healthy men (group A) and in 16 men with male-factor infertility (group B). PSA change (delta) was recorded and analyzed.
Results: Postejaculation serum PSA differed significantly from basal levels (p = 0.0037 by the Wilcoxon signed rank test). Following ejaculation, a rise was noticed in 74% of subjects. The median relative change in PSA concentration was 54%. No difference in respect to mean, median and relative change was observed between study groups. In two cases (6%), PSA rose from normal level to more than 4 ng/ml.
Conclusion: A significant postejaculation serum PSA elevation does occur, it is thus recommended that men abstain from ejaculation for 24 h prior to PSA sampling. Postejaculation PSA was not found to significantly correlate with hypofertility.

Canine prostatic diseases are usually asymptomatic in their onset and often identified in advanced stages. Canine prostatic specific esterase (CPSE) represents an early serum marker for prostatic diseases, also in asymptomatic dogs. The present study aimed to identify the effects of ejaculation on serum CPSE.

Acquisition of sperm capacitation post-ejaculation into the female reproductive tract is an essential step in the fertilization process. Accordingly, during in vitro fertilization, successful fertilization requires the induction of capacitation in epididymis-retrieved sperm. To date, many candidate substances have been considered as capacitation inducers; however, there are no reports on the efficiency of inducing sperm capacitation among the diverse inducers.

This study was undertaken to evaluate conventional and some of the main bio-functional spermatozoa parameters, serum gonadal hormones and didymo-epididymal ultrasound features in patients with type 1 diabetes mellitus (DM1). DM1 affects an increasing number of men of reproductive age. Diabetes may affect male reproduction by acting on the hypothalamic-pituitary-testicular axis, causing sexual dysfunction or disrupting male accessory gland function.
