Common Misconceptions About Progesterone After Ovulation

When our creator, Amy, realized her progesterone levels were not increasing properly after ovulation, she went to her doctor with this information and asked for a supplement. Despite hesitation, he recommended it for her. Amy went on for pregnancy – she delivered a beautiful baby – now 6. After Amy’s experience, she noticed there was a lack of awareness about low progesterone and hormone replacement.

Many women and their physicians did not recognize the strength of progesterone. Some myths still remain today. Here are some common theories about progesterone and how they can be stopping women from uncovering what should be an easy remedy.

What Is Progesterone?

Progesterone is stored in fat tissue and formed by the corpus luteum, a hormone-secreting structure that emerges from the follicle after an egg has been released. Progesterone is present in the ovaries, adrenal glands and placenta during pregnancy. Pregnancy activates progesterone, which is released to stimulate the uterine lining. Abnormal progesterone levels can affect the menstrual cycle.

Why Is Progesterone Important?when to start progesterone aft

Progesterone is released after ovulation. You need to prepare the uterus to accept an embryo, should conception have occurred and at sufficient levels after ovulation. What is lacking is the comprehension of the processes of defective hormone development. Doctors doubt whether low progesterone is a real diagnosis. Progesterone supplements may not help.

What Role Does Progesterone Play In Fertility

Progesterone performs many reproductive functions. Fertility releases progesterone after ovulation. Adequate quantities are required to conceive and sustain pregnancy. If this production is insufficient, progesterone supplement may be needed. When a woman conceives, progesterone plays a key role in thickening the uterine lining, enabling a developing embryo to adhere to the womb.

Before eight weeks gestation, progesterone development is primarily derived from corpus luteum. Progesterone levels are important to promote pregnancy during these early stages to avoid pregnancy loss. After ten weeks of gestation (including twelve in certain women), progesterone is primarily extracted from trophoblasts, which play a key role in nourishing the embryo and placenta.

Conception And Pregnancy?

Progesterone supplements are widely used in women with infertility diagnoses such as ovulatory disorders, repeated loss of pregnancy, and in combination with Assisted Reproductive Technology (In Vitro Fertilization, Embryo Transfer, Frozen Embryo Transfer, etc.) Progesterone supplements help offset low hormone output after ovulation.

What Infertility Issues Does Progesterone Help To Address?

When Amy asked her doctor for a progesterone supplement, he gave it to her, not because he felt it would work, but because it wouldn’t hurt her. This lack of confidence in progesterone supplements’ efficacy stems from a 2016 review. 836 women followed this report. When a woman had a positive pregnancy test, half had vaginal progesterone and the other half had none.

Live birth rates were only 2% higher in the progesterone supplement category. The study concluded that progesterone supplementation wasn’t very helpful. But the experiment was faulty. Basic biology tells us progesterone is needed to prepare the uterine lining for implantation, which is why the ovary releases it right after ovulation. But when a woman got a positive pregnancy test, the embryo had possibly already implanted.

Providing progesterone was almost “too late” after confirmed pregnancy – because progesterone is desperately needed to prepare the uterus for conception. When released, this study was highly publicized, so the knowledge spread widely to doctors and women.

Another research was published in 2017. In this experiment, women were given progesterone at the beginning of their luteal phase (3 days after ovulation) and should have high levels before becoming pregnant. This study’s findings revealed a 17% rise in live birth rates. Indeed, there are several studies showing progesterone supplementation beginning after ovulation, which increased live birth rates. Since the ovary releases progesterone right after ovulation, it is necessary to imitate the time when the body would have released as well – right after ovulation, not after implantation.


Keep informed and ask your doctor the right questions is the most important thing to do. The good news is that there’s a perfect way to confirm active home ovulation so you can appreciate this critical piece of fertility puzzle! After progesterone circulates through the blood, it passes through the liver where it is metabolized and secreted as PdG into urine (Pregnanediol Glucuronide).

Studies have shown that PdG levels in the first morning urine represent an average of the pre-day serum progesterone levels. Since PdG indicates an average, the total output of progesterone after ovulation is best measured. As the first at-home PdG test, Proov makes testing your levels quick! With Proov, you can measure urine from days 7-10 after peak fertility, when PdG is the strongest in healthy ovulatory cycles. If Proov isn’t positive during the test window, you might lack ovulation or suboptimal ovulation, which is something to discuss with your doctor.

Next, determine a patient’s medical background. Lack of normal menstrual cycles implies a condition like Polycystic Ovarian Syndrome. Previous pregnancy losses can suggest insufficient production of progesterone. In the woman with daily menses, correctly timed blood tests may be performed to determine progesterone levels.

An uterine lining biopsy can even be performed (although a rare practice these days) to assess a lack of progesterone influence. Progesterone is often used empirically, that is, only to make sure the amount is natural as you can’t get too much progesterone!

How Do You Determine If Someone Needs Progesterone?

Normal progesterone, used in fertility therapy, poses no danger to mother and child. The Food and Drug Administration (FDA) does not distinguish between natural progesterone and synthetic progesterone (progestins) in its warnings. Mostly, progestins are used to inhibit ovulation and are present in birth control pills.

Only used in preparation for fertility therapy. Older studies have linked synthetic progestin to a significantly increased risk of certain birth defects if used during pregnancy. The FDA performed a systematic review of related published research and found no rise in birth defects due to early pregnancy exposure to progesterone.

Is Progesterone Safe For My Baby And Me?

In these typical doses, a woman may be administered the following progesterone supplements:

What Different Types Of Progesterone Are Prescribed?

Crinone 8% (Vaginal Gel

Once Or Twice Per Day)

These three routes were shown to be similarly successful in fertility care. Less reliable:

Endometrin (Vaginal Tablets

100Mg 2-3X/Day)

The decision which progesterone replacement will be used depends on a physician’s judgment and personal preferences, as well as the specific condition of a patient. In the past, intramuscular injections were widely used due to lack of other preparations. Many studies found little difference in IVF treatment outcome compared to vaginal progesterone, and some also showed superiority of vaginal progesterone. Another benefit of vaginal progesterone is that it doesn’t induce intramuscular progesterone injections

Progesterone In Oil (Intramuscular Injection

50-100 Mg Once A Day)

Fertility care can be complicated and costly, whether insured or not. Several different types of medications can be administered which can vary depending on the type of care you receive. Progesterone, a natural hormone necessary for pregnancy, is a type of drug used in fertility treatments. Examples involve progesterone injections (also known as oil progesterone), Endometrin Prometrium, and Crinone Progesterone during the fertility therapy period.

Prometrium (Oral Tablets

In a normal ovulation cycel, progesterone increases just before ovulation and induces changes in uterine lining (the endometrial lining). This helps a uterine embryo to implant. Progesterone is necessary for sustaining a safe pregnancy before delivery. You may start taking progesterone at different points in your fertility treatment, depending on the type of treatment. Regardless of when the doctor starts progesterone, you can continue to use it for several weeks before the placenta begins to take over the development of natural progesterone.

Also Prescribed For Vaginal Use

200 Mg 1-2X/Day)

During an IVF cycle, where an embryo is transferred shortly after the eggs are recovered, progesterone is typically started 1-2 days after the ovary is removed.

Fertility Basics: Progesterone As A Fertility Med

Like other fertility medications, the policy does not cover progesterone, or you may have a high co-pay or coinsurance. Fortunately, you can also do certain things to reduce your prices. GoodRx provides daily pharmacy discounts and rates from MDR Pharmaceutical Care, a popular online fertility pharmacy. By shopping, you will save hundreds during your care. Endometrin also provides several manufacturers.

You will save up to $100 a month with Endometrin Instant Savings. The manufacturer even provides an assitance program to save uninsured patients even further on endometrin (and other fertility meds). There are no manufacturer discounts available in oil for Prometrium Crinone, or progsterone, but look at GoodRx or ask your doctor how to find a lower price. Additionally, progesterone in oil is a generic drug, meaning you’ll pay less. This is part of a series of fertility Dr. Mousa Shamonki’s guest blogs. Questions or requests for more information? Let’s tell.

As the name suggests, for conception and pregnancy, progest erone as in “progestation.” Yet we don’t hear much about this super hormone, which not only signals proper ovulation, but also prepares the uterus for a fertilized embryo for implantation.

Here’S What You Can Expect Depending On Your Particular Treatment:

You May First Receive Progesterone 1 – 3 Days After Ovulation.

Each menstrual cycle starts with relatively low progesterone levels. First, Follicle Stimulating Hormone (FSH) promotes the growth of an ovarian follicle, allowing an egg to mature and growing estrogen output. Then, as estrogen levels rise, production of FSH decreases, and production of Luteinizing Hormone or LH increases.

A increase in LH levels means that ovulation or an egg is about to occur. Many ovulation predictor kits measure LH, as this hormone is ovulation “predictive.” The luteal process, where the corpus luteum releases progesterone, follows ovulation. The corpus luteum is the empty follicle that released the egg. Progesterone presence suggests that ovulation actually occurred because if no egg is produced, there is no empty follicle or corpus luteum to produce it!
