Progesterone and Fertility

Fertility & Progesterone

Progesterone is recognized as a vital female hormone central to successful conception and a healthy pregnancy. The word "progesterone" is itself etymologically related to the Latin root gestare - meaning to bear or carry - suggesting the importance of this hormone in creating a fertile environment for conception and the continuing development of the embryo. (Many women report that FertilAid for Women has helped normalize their progesterone levels.)

In short, progesterone is a female sex hormone that is secreted by the corpus luteum to prepare the endometrium for implantation of the fertilized egg. Following implantation off the egg, the developing placenta signals the body to produce progesterone and prevent rejection of the developing embryo or fetus. Without this continuuing progesterone production, the endometrium would shed and menstruation would ensue. Therefore, progesterone plays a significant role in reproduction. Thus, progesterone...

  • Helps create a fertile, warm environment in the womb and promotes the survival of the fertilized egg through healthy implantation.
  • Strengthens and maintains the secretory endometrium which sustains the embryo throughout pregnancy.
  • Prevents the premature shedding of the secretory endometrium (menstruation).

As progesterone forestalls the shedding of the endometrium (where embryo implantation occurs), low progesterone levels - or a significant drop in progesterone levels - during the first few weeks of pregnancy may correspond with miscarriage.

Here, progesterone plays a 'secretory’ role in the reproductive organs. It stimulates changes in the uterus and supports pregnancy by increasing blood vessel and tissue development in the endometrium.

Progesterone, Fertility, and Reproduction

During a woman's cycle, progesterone levels rise rapidly at ovulation to provide a fertile environment for the fertilized egg. Here, progesterone is also responsible for the increase in body temperature at ovulation that lasts through most of the luteal phase. Beginning with ovulation, the corpus luteum produces progesterone for several days (and the concomitant temperature increase is in most cases easily measurable through methods of BBT/fertility charting).

If fertilization and implantation take place, the placenta takes over the role signalling progesterone production and in further maintaining a supportive environment for embryonic and fetal development. If fertilization does not occur, progesterone levels fall dramatically (usually after 10-12 days) triggering the shedding of the secretory endometrium (menses).

Because progesterone is essential in preventing the shedding of the secretory endometrium, a significant drop in progesterone levels during the first 10 - 12 weeks of pregnancy may result in a miscarriage.

Addressing the Issue of Low Progesterone Levels

Low progesterone can be detected by a blood test after ovulation or by charting fertility. Another sign of low progesterone is a shortened luteal phase that lasts less than 10 days.

There are several things you can do to boost deficient progesterone levels. Clearly, visiting a doctor to discuss the nuances of a particular issue may be the best first option. However, a fertility supplement, like FertilAid for Women, may help to bring progesterone levels into an ideal range for achieving pregnancy.

Women with a history of miscarriage can also use natural progesterone cream as soon as they know they have ovulated, to supplement their own progesterone; however, natural progesterone creams should not be used until ovulation takes place. Consult your physician for more information on the benefits of progesterone and uses/applications.

Other Applications of Progesterone

Progesterone has many other functions, among them protecting against fibrocysts, helping the body use fat for energy, and helping normalize blood clotting and blood sugar levels. Today, many health professionals claim that the symptoms associated with PMS and menopause are due not so much to estrogen, but to a deficiency of progesterone and an overabundance of estrogen. It is believed that progesterone balances estrogen and that an overproduction of estrogen can lead to health problems. However, consult your physician if you have any questions about using natural progesterone creams.

Hi,

I spoke with my doctor today regarding progesterone levels. Anything between 9 and 35 is considered normal. My level was 12 and they suggested that I take a supplement to boost the level to at least 15. My doctor said that there is nothing to worry about, however there is an increase in risk of miscarriage if your levels drop below 8. Progesterone is very important in early devolpment and helps aid in nourishment and development.

I just have received results from my blood work. I had bloodwork done on day 30 and have started my period on day 34. My progesterone levels were 20.4. I know you are suppose to have the bloodtest 7 days before your expected period but mine is hard to predict...
Does anyone know if this number is normal?
Last months was 14.
Thanks,
A

I recently had my progesterone levels checked and they came back at .6ng/mL and was wondering what this could mean. I am 27 years old and just finished nursing my son at 21 months old so 2 months ago. Could this cause my levels to be low? Also, I thought I was possibly pregnant when I got my blood drawn ( i had all the symptoms) and my period even came 5 days sooner and it was different ( i thought it may have been implantation bleeding), but as it turned out I was not pregnant. I started to worry that it would have been a miscarriage. Is a miscarriage possible with my progesterone levels being so low? Should we wait to get pregnant until my levels get higher?

Note that you are most likely to get pregnant if you time your lovemaking to occur on the days right before - and on - your ovulation date. Keep in mind that the projected ovulation date above is simply a “best guess” estimate based on your cycle date information. The most accurate way to pinpoint your most fertile time is through the use of urine-based ovulation tests or with a fertility monitor. We have partnered with Early-Pregnancy-Tests.com, the Internet’s leading supplier of preconception products since 2001, to offer low-cost, FDA-approved pregnancy and ovulation tests – with free same-day shipping.

 

Now that you’ve calculated your ovulation date using our ovulation calculator, we have a number of other helpful tools you can use to help increase your chances of conceiving.

 

  • Create your own personalized ovulation calendar! You can even provide an email address so that you receive email alerts of your most fertile days, when you can begin testing for pregnancy, and more.
     

  • Create your own personalized fertility chart! This is a highly accurate way to pinpoint your ovulation date that relies primarily on basal temperature charting. (Visit Early-Pregnancy-Tests.com for an accurate, inexpensive basal thermometer.)
