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.
An exact cause of infertility often can't be identified. Even if an exact cause isn't clear, your doctor might be able to recommend treatments or procedures that will result in conception.
In cases of infertility, it's also recommended that the female partner be evaluated by OB-GYN. This can help determine if she will require any specific treatments or if proceeding with assisted reproductive techniques is appropriate.
