About
Infertility is defined as trying to get pregnant with frequent, unprotected sex for at
least a year with no success.
Infertility is when you cannot get pregnant after having unprotected, regular sex for six months to one year, depending on your age.
Both men and women can have fertility problems. In about 20% of infertile couples, both partners have fertility problems. In about 15% of couples, no cause is found after all tests have been done. This is called unexplained infertility.
