Up to 15 percent of couples are infertile. This means they aren’t able to conceive a child, even though they’ve had frequent, unprotected sexual intercourse for a year or longer. In over a third of these couples, male infertility plays a role.

Male infertility is due to low sperm production, abnormal sperm function or blockages that prevent the delivery of sperm. Illnesses, injuries, chronic health problems, lifestyle choices and other factors can play a role in causing male infertility.

Not being able to conceive a child can be stressful and frustrating, but a number of male infertility treatments are available.
