BU: Moderate Drinking Does Not Affect Fertility

Moderate alcohol consumption does not affect a woman’s ability to get pregnant, but higher amounts might, according to a new study co-authored by Boston University School of Public Health (BUSPH) researchers.

Working with researchers in Denmark, a BUSPH team studied 6,120 Danish women enrolled in an Internet-based study who were in stable relationships with male partners and who were trying to conceive. Participants were asked in detail about their overall alcohol consumption, as well as intake of specific types of alcoholic beverages, including beer, wine, and liquor.

The researchers followed the women over nine years and adjusted for a number of factors, including time and frequency of intercourse.

The study, published by BMJ, found that women who drank fewer than 14 servings of alcohol a week (the equivalent of one to 13 four-ounce glasses of wine) were no less likely to conceive than those who abstained completely. Heavier drinking — the equivalent of two bottles of wine or more a week — was associated with an 18 percent decrease in fecundity.

The new study’s findings “did not support an effect of alcohol consumption at more moderate levels,” the authors wrote. “We observed no appreciable differences in the associations of consumption of beer and wine with fecundability,” while there was a slight reduction in fertility among women who drank only hard liquor.
