Mythbusters: Hot Tubs Bad for Men?

By Kathleen

You’ve probably heard the statement that hot tubs are bad for male fertility. The basic idea is that regular use of hot tubs will impair sperm production. Apparently this assertion was almost entire based on guessing, with little science behind it. Recently, a group of scientists put the theory to the test, which is summarized in this NYT article. After following a group of men who regularly used hot tubs, it was confirmed that sperm production and motility was impaired. Interestingly, most of the men were able to reverse the trend within a few months of cessation of hot tub use. It’s nice to know that we can continue to warn about this, but now with some actual science behind it.
