Warning to Men: Hot Tubs Really Will Damage Your Fertility
October 11, 2007
Men who are having trouble conceiving may want to stay out of the hot tub for awhile, according to a study by University of California researchers.
After analyzing data from infertile men who had been repeatedly exposed to high water temperatures from hot tubs, Jacuzzis, or hot baths for about 30 minutes a week, they found a strong link to their infertility.
In fact, all of the men had signs of infertility, including impaired sperm production and motility.
The good news is that the heat-induced damage appears to be reversible. When the men stopped their exposure to wet heat, total mean sperm counts increased by 491 percent after three to six months.
Among the men whose sperm counts did not increase, the researchers speculated that tobacco use may have been to blame, as most of the men whose sperm counts did not increase were chronic smokers.
