Heat decreased sperm count

Higher temperatures lead to an increase of testicular metabolism that results in spermatic damage. Oxidative stress is the main factor responsible for testicular damage caused by heat stress. The aim of this study was to evaluate lasting effects of heat stress on ejaculated sperm and immediate or long-term effects of heat stress on epididymal sperm. We observed decrease in motility and mass motility of ejaculated sperm, as well as an increase in the percentages of sperm showing major and minor defects, damaged plasma and acrosome membranes, and a decrease in the percentage of sperm with high mitochondrial membrane potential in the treated group until one spermatic cycle. An increased enzymatic activity of glutathione peroxidase and an increase of stressed cells were observed in ejaculated sperm of the treated group. A decrease in the percentage of epididymal sperm with high mitochondrial membrane potential was observed in the treated group.

Heat and Male Fertility

The testicles are located outside of the body because they need to be two to three degrees cooler than the rest of the body for optimal sperm production. The body has many effective mechanisms to keep scrotal temperature at ideal levels, and it can handle most weather- and exercise-related heat changes. In general, for every one-degree increase in ambient temperature, the scrotal temperature increases by only about a tenth as much. Still, despite these effective mechanisms, the testicles can be exposed to amounts of heat that cause problems with fertility.

According to the University of Rochester Medical Center, in order for males to create viable sperm, the temperature outside of the testicles has to be cooler than internally. If somehow the male beetle was able to produce in that temperature, their offspring had shorter than average lifespans, according to researchers. Our research shows that heatwaves halve male reproductive fitness, and it was surprising how consistent the effect was. Study authors hope the results will allow for more understanding of conservation efforts and the effect of climate change on humans.
