Male Infertility

Despite your best efforts, you and your partner have not been able to conceive a child. Like all couples struggling with fertility, you want to know what is causing the problem so you can focus your efforts on solutions that will help you realize your goal.

Infertility is linked to male factors in approximately 50% of cases. Diagnostic tests have been very successful in determining what the problem is and there are treatment options for many conditions. In some cases, however, the cause of infertility cannot be determined and remains unexplained.
