Drinking red wine could positively impact women’s chances of staying fertile for longer, according to a new study published in Fertility and Sterility magazine.

The study found that drinking red wine is associated with more antral follicles, a measure of the number of eggs a woman has for the future. Women who drank five or more servings of red wine per month had a greater number of eggs compared to women who drank other types of alcohol or less alcohol in general. Drinking less red wine, white wine, beer, and liquor didn’t have a correlation.

In the conclusion of the study, the authors write that resveratrol is likely behind the correlation.

“Resveratrol is a naturally occuring polyphenol found in higher concentrations in red wine, and it is known to have anti-inflammatory effects,” the study states. “Resveratrol may act to decrease reactive oxygen species at the level of the ovary, with moderate consumption of red wine, and is one proposed mechanism of higher AFC (antral follicle count) in our cohort.”

The study included 135 women between the ages of 18 and 45 with regular menstrual cycles. Pregnant women, women with a history of infertility, ovarian surgery, or major chronic illness were not included.

A lot more research needs to be done to link the correlation, but it’s another sign pointing to the fact that moderate red wine drinking is good for you thanks to resveratrol. Resveratrol is a naturally occuring compound in grape skins that studies have shown can do everything from inhibit the growth of tumors to lessening the risk of cardiovascular disease.

Now red wine lovers can add this latest study to their list of reasons to sip on a big red every wine Wednesday.
