Progesterone Pregnancy

Have questions about progesterone pregnancy? Do you know the normal progesterone levels during pregnancy? 

Should you consider hormone replacement for low progesterone levels during pregnancy? 

Difference Between Progesterone and Progestins

Progesterone is an important hormone to understand when thinking about hormones during pregnancy. When talking about taking progesterone during pregnancy, it's important to distinguish between progesterones and progestins. 

Natural progesterone is the exact same hormone that is produced by a woman's ovary. Progesterone is a natural substance where as progestins are synthetic. 

Progestins are synthetic progesterones manufactured in the lab. 

While progestins perform some of the functions of natural progesterones, they also block other important biological functions, such as the body’s own production of progesterone and may be harmful to the fetus during pregnancy.

Low Progesterone Levels in Pregnancy


Women taking progesterone while trying to become pregnant

The proper amount of natural progesterone is crucial to a woman who is trying to become pregnant. 

Natural progesterone prepares the uterine wall for implantation of the fertilized egg. 

The egg will be lost without adequate progesterone. 

In the case of ovulatory dysfunction, progesterone can also be used to help stimulate fertility. 

How progesterone helps a womans pregnancy...

  • Progesterone makes possible the survival of the fertilized egg


  • A progesterone surge at ovulation is the source of sex drive (libido)


  • Progesterone maintains the secretory endometrium which feeds the ovum and resultant embryo

Women with a history of miscarriage should begin using progesterone cream as soon as they know they have ovulated, to supplement their own progesterone and offset any environmental estrogen effects. 

The sudden drop in progesterone levels that's created by stopping the use of the progesterone cream can cause an abortion by bringing on menstruation. 

So if you want to be pregnant and you are also using progesterone cream, it's very important to keep using the cream until you find out for sure whether you're pregnant.  


Progesterone Pregnancy Solutions

Most doctors like to see a minimum level of 10 ng/ml during the first few weeks of pregnancy. If a woman has low progesterone levels this can be an indication of a threatened miscarriage. If you are concerned about your progesterone level, talk to your physician for more information. 

Progesterone is used to supplement what you are producing to ensure implantation. When you are pregnant, progesterone most importantly stops any signals to menstruate which occur if the progesterone levels were to drop. 

The hormone progesterone prepares the uterus for the fertilized ovum to help maintain pregnancy. 

An important benefit is that progesterone pregnancy supplements by increasing the lining of the uterus and makes the embryo "stick" to the lining. 


It's Important to Keep Progesterone Levels Up During Pregnancy

If a womans progesterone levels are too low in the beginning of pregnancy, there's a better chance the mother will miscarry. 

Oral progesterone, progesterone vaginal suppositories, and progesterone injections are three hormone replacement solutions for a woman to increase or just maintain a high enough progesterone level. 

Progesterone is first produced by the corpus luteum of the ovary and production from this site is necessary for the first 8 weeks of pregnancy. 

From implantation of the embryo onwards for 40 weeks the placenta takes over the production of progesterone. The levels of progesterone increase dramatically all throughout pregnancy. Progesterone production is necessary for the safe maintenance of pregnancy and all pregnancies will fail if progesterone in pregnancy production is too low.


Methods of Taking Progesterone during Pregnancy

When progesterone supplementation is given to a mother, its half life in the blood is very short. In four minutes it begins to be excreted rapidly into the urine. 

The most efficient route to take the progesterone to insure the best blood levels and the longest survival of the progesterone in the blood is to use vaginal suppositories. 

The next best route of administration is to take injections of progesterone. 
The least effective is to take the progesterone by mouth.
