Most experts define infertility as not being able to get pregnant after at least one year of trying. Women who are able to get pregnant but then have repeat miscarriages are also said to be infertile. Pregnancy is the result of a complex chain of events. In order to get pregnant:

• A woman must release an egg from one of her ovaries
• The egg must go through a fallopian tube
• 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 result from problems that interfere with any of these steps

If you are having a difficult time achieving pregnancy, talk to your doctor about diagnostic tests and treatment options available.
