What Are the Impacts of Consuming Alcohol During Early Pregnancy?

Drinking during pregnancy is associated with harm in exposed offspring, but what are the impacts of consuming alcohol during early pregnancy before pregnancy is known?

In the largest study of its kind, which was published in the British Medical Journal (BMJ), researchers revealed that moderate alcohol consumption does not affect a woman’s ability to conceive but that higher levels of alcohol consumption might lower their chance of conceiving.

Does Alcohol Affect Fertility?

A Danish and American team of scientists studied 6,120 Danish women ages 18-40 who were trying to conceive; they followed these women for over 9 years (69% of women being studied conceived). The women in the study were not necessarily infertile women, but simply women in a stable relationship who were trying to get pregnant.

The study revealed that women with low-moderate alcohol consumption (1-13 four ounce glasses of wine/week or its equivalence in beer or spirits) were just as likely to conceive than those who did not drink any alcohol. Heavy drinking, defined as 14 glasses of wine or more per week was associated with an 18 percent decrease in fertility.

The studies’ authors write that fertility was not affected by alcohol consumption at moderate levels. Those with moderate consumption of beer or wine showed no decrease in fertility while there was a slight reduction in fertility among women who drank only hard liquor.

There have been many studies that have looked at the question of alcohol consumption and fertility. Results have been all over the place with a few studies showing any level of alcohol intake lowers fertility and then some studies showing an increase in fertility with light to moderate alcohol intake. Of note, many of these studies had fewer that 200 women enrolled. However, many studies have shown what this study has shown that light to moderate alcohol consumption does not lower fertility.

Avoiding Alcohol During Ovulation

It is still important for women to abstain from alcohol during their “fertile window” and second half of their cycle until a pregnancy has been ruled out. Certainly alcohol consumption in early pregnancy can have major effects on the early fetus. However, if a woman is tracking her cycles, and knows when her fertile time starts, it is not unreasonable to have a glass of wine a few times per week as long as it is not during ovulation when trying to conceive.
