What Do All Those Hormones Do?

Do you know your female hormones and what they do? Understanding your body better can be of great help in your quest to get pregnant. Here's a quick guide to the primary hormones involved in ovulation:

  • Estrogen is produced primarily by the ovaries, and production increases prior to ovulation. The estrogen helps the uterus rebuild the endometrium (lining of the uterus) after menstruation, and estrogen also travels to the brain to increase or decrease the production of luteinizing hormone (LH) or follicle stimulating hormone (FSH).
  • Progesterone is also produced primarily by the ovaries in significant amounts during the two weeks or so that follow ovulation. Progesterone thickens the endometrium in preparation to receive the fertilized egg.
  • Follicle stimulating hormone (FSH) is also produced by the pituitary gland and helps regulate the menstrual cycle and the production of eggs by the ovaries. The amount of FSH in a woman's body is highest just before she ovulates.
  • Luteinizing hormone (LH) is produced by the pituitary gland and helps regulate the menstrual cycle and ovulation. The level of LH increases rapidly just before ovulation occurs, which is called the LH surge.
