Climate change affecting sperm counts

The s saw significant development in the research on male infertility where reliable results proved a decline. Soy is notably found in tofu, but it's also a common ingredient in health drinks, meat alternatives, and protein bars. Unfortunately he followed through and booted me in the plums.

In human males, the testicles make sperm and, to do this, the temperature of the testicles needs to be cooler than the inside of the body, according to the University of Rochester Medical Center.

In human males, the testicles make sperm and, to do this, the temperature of the testicles needs to be cooler than the inside of the body, according to the University of Rochester Medical Center. It's not good news.

Richardson and her colleagues found that earlier research claimed causal links between declining sperm counts and declining fertility, as well as between exposures to certain environmental chemicals and lower sperm counts. Insects in nature are likely to experience multiple heatwave events, which could become a problem for population productivity if male reproduction cannot adapt or recover. And one answer could be related to sperm. New findings published today in the journal Nature Communications reveal that heatwaves damage sperm in insects -- with negative impacts for fertility across generations.
