Introduction to Estrogen and Progesterone Function

Pregnancy and the progesterone Function

There are two main hormones that are vital for a viable pregnancy to be carried to full term: estrogen and progesterone. Both of these hormones are primarily produced in the ovaries and used throughout a woman’s life.

These crucial hormones are there to help regulate the many changes that are going on throughout a woman’s body before and during pregnancy. Estrogen plays a vital role in the fetus’s growth and development, such as helping the uterus grow and maintaining the uterine lining. However, this article’s focus is primarily on progesterone function and how it affects pregnancy.

Keep in mind that it is important to have both these hormones at proper levels for fetal development and to aid in carrying a healthy baby to full term. If the hormonal levels are not balanced properly it will cause a hormonal imbalance such as estrogen dominance, where there is more estrogen than needed and lower amounts of progesterone.

Progesterone is an important ovarian hormone in the female reproductive system for several reasons. This hormone is produced in the ovaries and aids in menstruation, menopause, egg implantation and fetal development. Insufficient amounts of this much-needed hormone can have big effects, especially during pregnancy. The main function of progesterone is really progestational or the process of keeping the fetus healthy within the womb, and keeping it in the womb until it is full term. The fetus cannot survive without these proper levels of the hormone progesterone.

Repeated miscarriages or babies being stillborn may be caused by inadequate levels or lower than normal levels of progesterone, especially during the first trimester. This is often why some mothers may miscarry a defective or stillborn fetus. This happens because progesterone function plays a significant role in fetal development and implantation of the embryo.

In the first 12 weeks of pregnancy, the function of progesterone is quite important and a woman needs high levels in order to prevent miscarriage. If your body is producing lower levels of this key hormone, there may be problems with implantation that would result in a miscarriage.

This is why some women may have to have progesterone therapy before or during pregnancy. There are various forms of progesterone therapy including:

  • Oral Pills
  • Injections
  • Vaginal Inserts or Suppositories

Just like any type of hormonal replacement therapy or other conventional types of medicine, there are potential risks to undergoing progesterone replacement therapy that may include: blood clots, gallbladder problems, skin irritations and even cancer.
