TL;DR: In contrast to vitamin B supplementation, vitamin E and selenium supplementation produced a significant decrease in MDA concentrations and an improvement of sperm motility, and these results confirm the protective and beneficial effects of Vitamin E and Selenium on semen quality and advocate their use in male infertility treatment.
Abstract: Numerous studies have reported beneficial effects of antioxidant drugs on semen quality, but there is no well-defined therapeutical protocol in male infertility. This study aimed to test the effect...

TL;DR: The data indicate that some RPL patients have a significant increase of sperm DNA fragmentation, which may be causative of pregnancy loss in some patients.
Abstract: Previous studies have indicated that sperm quality may be related to unexplained recurrent pregnancy loss. This study evaluated the degree of sperm DNA fragmentation using the TUNEL assay on sperm from 24 couples with unexplained recurrent pregnancy loss (RPL) compared to sperm from 2 control groups: donors of known fertility and unscreened men from the general population. The percentage of sperm staining positive for DNA fragmentation was increased (p < .001) in the RPL group (38 +/- 4.2) compared to the donor (11.9 +/- 1.0) or general population (22 +/- 2.0) control groups. In the RPL group, no correlation was observed between semen quality parameters and the TUNEL data. These data indicate that some RPL patients have a significant increase of sperm DNA fragmentation, which may be causative of pregnancy loss in some patients.

TL;DR: The prolonged use of cell phones may have negative effects on the sperm motility characteristics, and the duration of possession and the daily transmission time correlated negatively and positively with the proportion of rapid progressive motile sperm.
Abstract: This study was conducted to determine a possible relationship between regular cell phone use and different human semen attributes. The history-taking of men in our university clinic was supplemente...

TL;DR: The incidence of hyperactivated movements by fertile and oligozoospermic spermatozoa could be significantly increased after exposure to various motility stimulants.
Abstract: Suspensions of capacitating human spermatozoa were analyzed for potential hyperactivated movements using videomicrographic methods. Analysis was carried out on aliquots of 22 sperm suspensions, which were proved fertile several hours later during human in vitro fertilization. After approximately 3 h of capacitation, 22.1% of the fertile spermatozoa displayed motility patterns designated as hyperactivated. Over 80% of these hyperactivated spermatozoa moved with a wide-amplitude, two-dimensional whiplash pattern, displaying marked lateral displacement of the head. Only 8.4% of capacitating spermatozoa from oligozoospermic patients showed these hyperactivated movements. The incidence of hyperactivated movements by fertile and oligozoospermic spermatozoa could be significantly increased after exposure to various motility stimulants. The clinical significance of hyperactivation as a functional assay of fertilizing capacity is discussed.

TL;DR: In these experiments, passive immunization against testosterone in intact male rats produced a clearcut stimulation of both LH and FSH release, but produced no data to support the suggestion that the intact testis can secrete nonsteroidal compounds capable of producing a differential inhibition of FSH secretion.
Abstract: Subcutaneous Silastic implants were designed to release quantities of testosterone approximating that produced by the rat testis and appropriate testosterone treatment was found to produce a physiologic inhibition of both LH and FSH secretion in orchidectomized rats. In rats bearing such testosterone implants, intravenous injection of an ovine anti-testosterone serum (0.3 cc) was sufficient to completely abolish the inhibitory effects of the testosterone implant for a period of 3 days as judged by the development of typical post-castration increases in serum LH and FSH. When this dose of antiserum was administered to intact adult male rats, the increases in serum LH on days 1, 2, and 3 post-injection were approximately 19%, 15%, and 11% of those observed in untreated castrates. Increases in serum FSH in antiserum injected rats followed a pattern similar to that for serum LH but the response was slightly greater (19%, 23%, and 22% of the castrate response) and there was no indication of a decreasing effect...
