The question of whether to drink while trying to conceive is complicated. Unlike caffeine, where moderate amounts appear safe, alcohol exists in a grayer zone—especially since any amount is considered risky once you're actually pregnant.
What the Research Shows
For Women
- Heavy drinking (7+ drinks/week): Consistently associated with reduced fertility, longer time to conception, and lower IVF success rates
- Moderate drinking (3-6 drinks/week): Some studies show reduced fecundability (monthly chance of conception), others show no effect
- Light drinking (1-2 drinks/week): Most studies show minimal impact on time to conception, but research is mixed
- Binge drinking: Even occasional heavy drinking episodes may affect ovulation and egg quality
For Men
Alcohol affects male fertility too, though men's reproductive systems are more resilient to moderate intake:
- Heavy drinking can reduce testosterone and sperm quality
- Moderate drinking appears to have minimal impact for most men
- Effects are more reversible than for women—sperm regenerates every 72 days
There is no known safe amount of alcohol during pregnancy. Since you won't know you're pregnant until a few weeks in, drinking during the two-week wait means potentially exposing an early embryo to alcohol. This is the strongest argument for abstaining when actively TTC.
A Cycle-Based Approach
If complete abstinence feels overwhelming, some women use a cycle-based approach:
Menstruation (Days 1-5)
Lowest risk window. Occasional drink unlikely to affect next cycle's egg.
Follicular Phase (Days 6-12)
Eggs are developing. Consider limiting to 1-2 drinks for the week.
Ovulation (Days 13-15)
Conception window. Best to avoid—you want optimal conditions.
Two-Week Wait (Days 16-28)
You could be pregnant. Most experts recommend avoiding alcohol entirely.
During Fertility Treatment
Most fertility clinics recommend avoiding alcohol entirely during IVF and other treatments. Research suggests even moderate drinking may reduce IVF success rates. The medication protocols also place extra demands on your liver.
You may have heard the phrase "drink till it's pink" (meaning drink until you get a positive test). While this was once common advice, most fertility specialists now recommend the opposite approach—especially during the two-week wait. Early pregnancy (before you can test positive) is actually when alcohol poses the greatest risk to fetal development.
Practical Strategies
- Find enjoyable alternatives: Mocktails, sparkling water with lime, non-alcoholic wines and beers have improved dramatically
- Reframe social situations: You can say you're "taking a break" or "on medication" to avoid fertility questions
- Plan ahead: Bring your own drinks to parties so you're not stuck with just water
- Get your partner on board: It's easier when you're not drinking alone (metaphorically)
What About Occasional Drinks?
If you have an occasional drink during the follicular phase (early cycle, before ovulation), it's unlikely to have a significant impact on your fertility. The anxiety about "ruining" your chances with a single glass of wine is probably worse for your fertility than the wine itself.
That said, if you're undergoing fertility treatment, have been trying for a while, or simply want to optimize every factor you can control, abstaining is the safest choice.
