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 sp@rm 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 release counts increased by 491 percent after three to six months
Other research has shown heat from laptop use and wearing tight underwear can reduce fertility the Journal of the Brazilian Society of Urology reports.
The researchers from the University of California, San Francisco, said although it had been believed for decades that ‘wet heat’ could damage fertility, there had been very little research.
Men attending a fertility clinic who were exposed to more than 30 minutes per week of ‘wet heat’ through hot baths, Jacuzzis or hot tubs, were recruited to the study.
After three to six months of staying out of the bath, just under half the men showed dramatic five-fold improvement in release count.
motility increased from 12% to 34% in the men who responded to cutting out baths.
