Semen analysis

TL;DR: The findings provide the evidence that PE exposures are related to male reproductive function and raise a public health concern because that exposure to PEs is ubiquitous in China.

TL;DR: While some of these proteins are up-regulated in men with oligozoospermia and varicocele, HSFY is up- regulated only in the presence ofvaricocele and especially in menWith normozoopermia, which suggests that it may be a molecular marker of an adequate or inadequate response to the damaging effect of varicoCele on spermatogenesis.

TL;DR: The presence of clinical varicocele in fertile men is not associated with higher seminal ROS levels or abnormal semen parameters, and levels of ROS are not correlated withvaricocele grade or testis volume in the same population of fertile men.

TL;DR: The motility of infertile sperm was also found to correlate positively with the seminal levels of bicarbonate as mentioned in this paper, suggesting that the lowered levels of Bicarbonates in semen are at least in part responsible for the poor sperm motility in the patients with male infertility, as a result of the failure in the activation of sperm adenylate cyclase.

TL;DR: It is seen that the presence in semen samples of S. marcescens, K. oxytoca, M. morganii, or P. mirabilis, but not P. stuartii or E. coli, was negatively associated with sperm motility, and bacterial contamination should always be examined in sperm samples prepared for artificial insemination.
