Alcohol consumption can negatively impact IVF success rates. Studies have shown that drinking more than four drinks per week before an IVF cycle is associated with:
- A 48% higher risk of failed fertilization
- A 21% lower chance of a live birth
- A 13% decrease in the number of eggs retrieved
- An 18% greater odds of failed implantation
- A 26% reduced chance of a baby
Drinking up to one alcoholic drink per day while undergoing treatment does not affect success rates. However, as a patient approaches IUI or egg retrieval, it is recommended to cease all alcohol intake due to possible risks to the early embryo and fetus. It is ideal to stop/reduce alcohol consumption for at least three months before attempting pregnancy.
