Alcohol and Marijuana

While medical authorities agree that excessive consumption of alcohol can impair fertility, it's still unclear what the effect of moderate consumption is. The same applies to marijuana. Health care providers often advise couples to err on the side of caution with regard to substances that could potentially impair their chances of conceiving.

Some studies suggest that the more alcohol a woman consumes beyond one or two drinks per day, the lower her chances of becoming pregnant. A Danish study, published in 1998, suggests that while women with high alcohol consumption take longer to become pregnant, no studies had indicated that moderate drinking significantly impairs female fertility. On the other hand, a study published in Fertility and Sterility revealed decreased fertility in women who had an average of only one drink per day. 

eggsNew research does indicate that marijuana use not only inhibits the ability of sperm to fertilize eggs, but that high concentrations of THC (the psychoactive ingredient in marijuana) may cause structural damage in sperm as they fuse with a woman's egg. Most studies, however, involved "heavy" marijuana users, and some researchers say it's still unclear how occasional marijuana use might impact fertility.

Researchers say there's little doubt that heavy alcohol and/or marijuana use can impair a couple's chances of conception, since heavy use can reduce desire and sexual function.

Your fertility specialist can best assist you in making lifestyle choices that complement your infertility treatment and pave the way for a healthy pregnancy.
