Infertility, defined as the inability to achieve pregnancy after one year of unprotected intercourse, affects up to 15% of all couples. Although women are usually the first to be evaluated, approximately 40% of infertility cases are due to male factors.
For approximately 40 percent of couples who are experiencing infertility, the problem is at least in part related to male reproductive issues. It is essential that men be assessed to pinpoint the treatable or untreatable causes of male infertility.
