title: Effects of acute restraint stress on sperm motility and secretion of pituitary, adrenocortical and gonadal hormones in adult male rats.
abstract: The effects of acute restraint stress on sperm motility and reproductive endocrinology were investigated in adult rats. Sperm motility was determined by computer-assisted sperm analysis. Acute restraint stress reduced sperm motility starting after 30 min, and the sperm motility parameters, percentage of motile spermatozoa (%), straight-line velocity, curvilinear velocity, deviation of the sperm head from the mean trajectory and the maximum amplitude of lateral head displacement decreased. It also induced a significant elevation in plasma adrenocorticotropic hormone, prolactin, corticosterone and progesterone and decreased follicle-stimulating hormone, luteinizing hormone, testosterone and immunoreactive (ir-) inhibin. These results clearly demonstrated that the acute restraint stress rapidly suppressed sperm motility and increased the activity of the hypothalamus-pituitary-adrenal axis, whereas it disturbed hypothalamus- pituitary-gonadal axis activity.
