Fertility Facts and Figures

For normal fertile couples trying to conceive, the chance of succeeding in any given month is about 20 percent.

About 57 percent of couples will conceive within three months.

About 75 percent of couples will conceive within six months.

About 90 percent of couples will conceive within one year.

Infertility affects men and women almost equally.

In both sexes, fertility declines with age, but age-related fertility problems are far more likely in women.

In men, fertility declines after age 50.

In women, fertility starts to decline beginning around age 30:

Among women age 15 to 24, 4 percent have difficulty conceiving.

Among women age 24 to 34, 13 percent have difficulty conceiving.

By age 40, 34 percent of women have difficulty conceiving.

By age 45, 87 percent of women are infertile.

In the United States, about 1 in 5 women (20 percent) have their first child after age 35. A woman age 35 has one half the chance of having a successful pregnancy compared with a woman age 25.
