(MY026) More sex may help damaged sperm

LONDON – For men with fertility problems, some doctors are prescribing a very conventional way to have a baby: more sex.
In a study of 118 Australian men with damaged sperm, doctors found that having sex every day for a week significantly reduced the amount of DNA damage in their patients' sperm. Previous studies have linked better sperm quality to higher pregnancy rates.
The research was announced Tuesday at a meeting of the European Society of Human Reproduction and Embryology in Amsterdam.
Dr. David Greening of Sydney IVF, a private fertility clinic in Australia, and colleagues looked at 118 men who had damaged sperm. Greening and colleagues told the men to have sex every day for a week. After seven days, the doctors found that in 81 percent of the men, there was a 12 percent decrease in the amount of damaged sperm.
Many fertility experts suggest men abstain from sex before their partners have in-vitro fertilization, to try to elevate their sperm counts.
Sperm quality can also be improved if men don't smoke, drink moderately, exercise, or get more antioxidants.
