Alcohol has been shown to affect male and female fertility, but the level of consumption associated with risk is unclear.

The mechanisms by which alcohol could impair fertility are unclear, but in men it can cause impotence, reduce libido and affect sperm quality.
The National Health and Medical Research Council guidelines for alcohol consumption suggests that for healthy men and women, drinking no more than two standard drinks on any day reduces the lifetime risk of harm from alcohol-related disease or injury, including the negative affects on fertility.
A study of couples undergoing assisted reproductive treatment that looked at male and female alcohol consumption in the year prior to treatment as well as during treatment found both male and female alcohol consumption decreased the chance of a live, healthy baby and increased the risk of miscarriage.
