Infertility

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 (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 result from problems that interfere with any of these steps. Numerous studies have documented the role of progesterone, the 'pregnancy hormone,' in preparing a woman's body for pregnancy and helping her to maintain a pregnancy. During the pregnancy, progesterone is needed in the following ways: Makes the endometrium develop and secrete fluids after being primed by estrogen Maintains the functions of the placenta and fights off unwanted cells near the womb that could cause damage to the placenta or fetus. Keeps the endometrium in a thickened condition Stops the uterus making spontaneous movements Stimulates the growth of breast tissue Prevents lactation until after the birth (with estrogen) Strengthens the mucus plug covering the cervix to prevent infection. Strengthens the pelvic walls in preparation for labor. Stops the uterus from contracting (thus keeping the baby where it is)
