Progesterone prevents pregnancy

How does Progesterone prevent Pregnancy?

Progesterone is a primary hormone coordinating your menstrual cycle and pregnancy. You need the right amounts of progesterone at the right times to become pregnant, as well as have good fetal development and a successful labor. For this reason it is a crucial hormone when the time comes to start a family.

When an egg (ovum) is released from your ovary during the menstrual cycle, progesterone levels rise, preparing your uterus lining for a fertilised egg and also helping the placenta form once pregnancy begins. During pregnancy, progesterone aids your fetus’ development and readies your body for childbirth and nursing. Progesterone levels continue rising throughout pregnancy, until your baby is born.

 

Too Much Progesterone Prevents Pregnancy

Normally, when you release an egg (ovum) during your menstrual cycle, your progesterone levels rise. This triggers a stoppage to the production of anymore eggs. But if your progesterone levels are already high, which can occur due to various factors including poor health or birth control pills, your ovaries are tricked into not releasing any eggs at all.

 

Low Progesterone Prevents Pregnancy

If your egg (ovum) does not become fertilised during a normal menstrual cycle – by design or chance – your progesterone levels will naturally drop. This signals your body to begin menstruation. However, abnormally low progesterone levels may trick your body into frequent or irregular menstruation. This may prevent pregnancy or cause miscarriage or early labour.

 

What Else Does Progesterone Control?

Besides controlling ovulation and pregnancy in women, progesterone is involved in the production of other adrenal primary hormones, including cortisol, testosterone, and estrogen. All these must be in balance for good health. Progesterone imbalances can cause infertility, weight gain, low sex drive, and depressive symptoms. In men, progesterone influences sperm production and sexual behaviour.

 

Rule Out the Progesterone Factor

Worry won’t help you. Facts will. Get your progesterone levels tested one way or the other if you are concerned. It can be done easily and at home. For Australian women, TestoChecker’s G1 and G2 Fertility Test Kits can be used to check the expected rise in Progesterone as well as other hormones relevant to fertility hormone health.

If your concerns relate to physical symptoms causing either physical or mental distress, consult your family doctor immediately.
