Consuming three to five drinks in a night while trying to conceive is a detrimental practice that reduces fertility and the likelihood of a successful pregnancy.

“Again and again, what we're seeing is that consuming more than one or two drinks per week of alcohol is really detrimental to the entire process of fertility and the entire process of healthy pregnancy. And that's true from both the male side and the sperm, and it's true from the female side and the egg.”

“So my simple advice on this is if you are wishing to have a healthy fertilization and pregnancy, the best thing to do would be avoid alcohol altogether and, if you are going to drink, to really limit that drinking to one or two drinks per week maximum.”

“And so this idea of going out and having three or four drinks or four or five drinks in a given night at a time in which you're also trying to conceive children, the biology tells us, the epidemiology tells us that this is just a terrible idea. It's going to reduce the likelihood of fertility and successful pregnancy.”
