Drinking a Single Glass of Wine Daily Can Reduce Likelihood of Pregnancy by 18%

wineA new study seems to suggest the negative effects linked to drinking wine, especially for women. The medical advice for women, when it comes to wine drinking, dates back to as far as 1947. However, the results of a new study indicate that a large glass of wine consumed by women each night harms their chances of being fertile and having a baby.

The researchers of the current study found out that the chance of pregnancy is reduced by 18% in 12 months for women who drink approximately 240ml of wine regularly at night. A 240ml glass of wine is also equal to two bottles of beer or even two shots of spirits. The current research was published in BMJ.

If one is to look at the current guidelines by NHS, it is recommended that females who are trying to get pregnant shouldn’t drink. However, there hasn’t been much scientific evidence showing that the chance of conception is linked to the amount of alcohol consumed.

More than 6,000 women were part of the Danish study. All of the women were between the ages of 21 and 45. They had been trying to get pregnant for a year. The results were matched against the women’s drinking levels by the researchers.


The results of the study showed a drop of 18% in conceiving rate in women drinking 14 or even more servings of alcohol per week. This consumption was equal to drinking seven large glasses of wine in a week. The researchers conclude that due to drinking too much one in five women, who could’ve gotten pregnant otherwise, failed to conceive.

According to Ellen Mikkelsen, who is the lead author of this study from Aarhus University Hospital in Denmark, “For many women of reproductive age, alcohol consumption is an integral part of their lifestyle. In this prospective study of women trying to conceive, consumption of the highest amount of alcohol was associated with an decrease in fecundability compared with no alcohol consumption.”

The level of drinking that starts to impact the fertility rate of women is approximately two glasses more than what the NHS currently recommends, which is 14 units per week. Each unit is equal to about 87ml of wine. The results of the study also went on to show that the fertility rates in women who drank less didn’t change.


As suggested by experts in Britain, the current study indicates that women who drank on occasion were unlikely to experience reduction in their pregnancy rate. Annie Britton, of University College London, said the results of the new research serves as a sort of reassurances to couples who are trying to get pregnant.

She added that letting go of drinking altogether doesn’t seem to be necessary or plays a role in increasing the rate of conception. Women can still consume alcohol in moderate amounts without their fertility being affected.

She further went on to advice that binge drinking should be avoided by women. As doing so can potentially disturb their menstrual cycles and bring harm to a baby during the early stages of pregnancy. For a couple who is experiencing difficulty in getting pregnant it is advised that alcohol intake should be reduced by both partners.
