Dr. Bruce Redmon in the Department of Medicine spoke to USA Today about a recently published study that found men are likely to have lower sperm counts than 50 years ago. Dr. Redmon, who was not involved in the study, said it’s challenging to study sperm counts and not really feasible to sample sperm in a randomly selected population of men every year for decades. Overall, however, he said the study is a reasonable way to look at the issue. "It's probably something we have to continue to take seriously and look at," Dr. Redmon said. 

According to experts, a decreasing sperm count could mean that it takes longer to have children. The study shows that men in North America, Europe and Australia have sperm counts that have continued to fall since 2017. Experts say this should be a wakeup call.
