Male Factor Infertility
Infertility is a disease deﬁned by the failure to achieve a successful pregnancy after 12 months or more of regular unprotected intercourse. Earlier evaluation and treatment may be justiﬁed based on medical history and physical ﬁndings and is warranted after 6 months for women over age 35 years. Ten to fifteen percent of couples will experience infertility. A male factor is present in up to half of cases of infertility and often can be treated.
