Having more sex helps men with fertility problems boost the quality of their sperm, says an Australian study that included 118 men with damaged sperm.
When the men had sex every day for a week, 81 percent of them had a 12 percent reduction in the amount of sperm with damaged DNA, the Associated Press reported.
The study was presented at a meeting of the European Society of Human Reproduction and Embryology.
Experts note that if sperm is in the body for too long, it's more likely to get damaged, the AP reported.
Other ways of improving sperm quality include not smoking, drinking in moderation, exercise, and consuming more antioxidants.
