- Infertility is fundamentally the inability to conceive a baby. Infertility also refers to the state of a woman who is unable to carry a pregnancy to full term.
World Health Organization
- "Infertility is the inability to conceive a child. A couple may be considered infertile if, after two years of regular sexual intercourse, without contraception, the woman has not become pregnant (and there is no other reason, such as breastfeeding or postpartum amenorrhea). Primary infertility is infertility in a couple who have never had a child. Secondary infertility is failure to conceive following a previous pregnancy."
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 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)
