Understanding Infertility

What is infertility?

Graphic: Illustration of two calendars in circles, one marked “12+ months” and the other marked “6+ months.”

Infertility is the inability to achieve pregnancy after 12 months or more of regular, unprotected sexual intercourse (or after 6 months if the woman is older than 35). The term describes men who can’t get a woman pregnant and women who can’t get pregnant or carry a pregnancy to term.

About 9% of men and about 11% of women of reproductive age in the United States have experienced fertility problems.

Many couples experience infertility. The causes can be from factors in the female, factors in the male, or a combination of factors from both the female and the male.

What types of things can cause or contribute to infertility?

Health conditions and behaviors, age, genetics, and other factors can all cause or contribute to infertility in men and women.

  • Gynecological disorders such as polycystic ovary syndrome (PCOS), primary ovarian insufficiency (POI), endometriosis, and uterine fibroids.
  • Problems with anatomy of the reproductive organs

What’s age got to do with it?

People are waiting longer than ever before to start families. In fact, about 20% of women in the United States now have their first child after age 35.

As age increases, so does the likelihood of infertility.

  • Older men produce fewer sperm and lower-quality sperm.
  • Older women have fewer eggs and lower-quality eggs.
  • The risk of some health conditions associated with infertility (above) increases with age.
  • Age-related declines in sperm and egg quality increase the risk of health conditions, such as Down syndrome, autism, and schizophrenia, in future generations.

After age 30, a woman’s fertility decreases rapidly every year until menopause, usually around age 50. In the decade before menopause, her fertility is also greatly reduced. Male fertility also declines with age, but more gradually.

What now?

Get informed! Learn the risk factors for infertility, and ask your healthcare provider any questions you have about your ability to conceive and the natural course of fertility through your lifespan.
