Viagra may harm sperm and fertility Viagra may be good for boosting a man's sex life, but it also may harm sperm and fertility, according to a new study.

The British study concluded that young men who take the drug could be ruining their chances of fathering children, it is reported by Australian news agency AAP.

Dr. David Glenn, a consultant gynecologist at Queen's University Belfast, conducted two experiments on Viagra, which will be published in the journal Fertility and Sterility, according to the report.

In the first, Glenn and his research team treated sperm samples with weak solutions of Viagra to mimic the level found in the blood of a man who has taken a single pill.

Sperm exposed to the drug appeared more active than untreated sperm. But the Viagra also appeared to damage the acrosome, a cap-like structure that produces enzymes to help penetrate the egg, the report said.

The second test found that mice given Viagra produced 40 percent fewer embryos than other mice.

Pfizer, maker of Viagra, was not immediately available for comment, the report said.

About Catherine: I am mom to three grown sons, two grandchildren and two rescue dogs. After years of raising my boys as a single mom, I remarried a wonderful man who had never had a child of his own. Unexpectedly, I found myself pregnant at 49!
Sadly we lost that precious baby at 8 weeks, and decided to try again. Five more losses, turned down for donor egg, foster care and adoption due to my age and losses - we have accepted that there will be no more babies in our house.
