PY - 2021 T2 - Essentials of Men’s Health AB - Infertility is defined as the inability of the couple to achieve a successful pregnancy after 12 months of unprotected intercourse if the woman is under age 35, or after 6 months of unprotected intercourse if a female partner is greater than 35 years old. Infertility affects close to 15% of all couples trying to conceive a pregnancy. In 20% to 30% of such couples, infertility can be clearly identified as due to female causes, and in 20% to 30% of cases infertility can be clearly attributed to male-factor problems. The remaining cases are classified as “unexplained,” where no specific abnormalities can be identified in either of the partners.
