What is infertility?
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 must release an egg from one of her ovaries (ovulation).
- The egg must
go through a Fallopian tube toward the
- 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.
Is infertility a common problem?
Yes. About 10 percent of women (6.1 million) in the United States ages 15-44 have difficulty getting pregnant or staying pregnant, according to the Centers for Disease Control and Prevention (CDC).
Is infertility just a woman's problem?
No, infertility is not always a woman's problem. Both women and men can have problems that cause infertility. About one-third of infertility cases are caused by women's problems. Another one third of fertility problems are due to the man. The other cases are caused by a mixture of male and female problems or by unknown problems.
What causes infertility in men?
Infertility in men is most often caused by:
- A problem called varicocele (VAIR-ih-koh-seel). This happens when the veins on a man's testicle(s) are too large. This heats the testicles. The heat can affect the number or shape of the sperm.
- Movement of the sperm. This may be caused by the shape of the sperm. Sometimes injuries or other damage to the reproductive system block the sperm.
Sometimes a man is born with the problems that affect his sperm. Other times problems start later in life due to illness or injury. For example, cystic fibrosis often causes infertility in men.
