My boyfriend drinks beer everyday , will that effect his sperm to not be able to make his spouse conceive ?

Best to limit: It is unclear if 1-2 drinks per day will have an effect on his ability to father a child. Higher dose, 3 or more a day or binge drinking may. It is safest for him to limit how much he drinks.

alcohol can affect fertility: Yes alcohol can definitely reduce fertility rates in both men and women. The recommended drinks per week are quite low for both men and women. Women it's two drinks a day or in total of four a week. For man it's between 14 and 30 drinks a week. Or maximum four drinks a day.
