Fertility and Infertility

“Infertility” is a term that describes when a couple is unable to achieve pregnancy after 1 year of having regular, unprotected sex, or after 6 months if the woman is older than 35 years of age.

The term “infertility” also is used to describe the condition of women who are able to get pregnant but unable to carry a pregnancy to term because of miscarriage, recurrent pregnancy loss, stillbirth, or other problems.

Recurrent pregnancy loss is considered distinct from infertility. Although there may be some overlap, the causes of pregnancy loss, recurrent pregnancy loss, and stillbirth are often different from the causes of infertility.
