Does coffee make me more or less likely to get pregnant?

Varies: More than two cups a day seem to affect the way an egg is picked up by the fallopian tube. If you are trying to conceive, best to stick to 1-2 cups per day.

Miscarriage risk: As far as we know, coffee intake has no effect on getting pregnant. One study found an increased miscarriage risk at a caffeine intake of two cups of coffee a day or more (or 5 12 oz caffeinated sodas) ... So we recommend one cup of brewed coffee a day and decaf for the rest. Espresso drinks are much higher in caffeine and should be avoided unless decaf; tea is lower in caffeine than coffee.
