Infertility means not being able to get pregnant after one year of trying, or six months, if a woman is 35 or older. Women who can get pregnant but are unable to stay pregnant may also be infertile.

Pregnancy is the result of a process that has many steps. To get pregnant:

• A woman’s body must release an egg from one of her ovaries (ovulation).
• The egg must go through a fallopian tube toward the uterus (womb).
• A man’s sperm must join with (fertilize) the egg along the way.
• The fertilized egg must attach to the inside of the uterus (implantation).

Infertility can happen if there are problems with any of these steps.
