A miscarriage is a traumatic experience for every mother-to-be. A miscarriage can stop you from experiencing and enjoying motherhood; hence many doctors or gynaecologists generally prescribe progesterone supplements to a pregnant woman to ensure that she has a safe delivery.
Progesterone is a hormone associated with the menstrual cycle and pregnancy. But, the use of progesterone supplements during pregnancy to prevent miscarriage is highly debatable. The hormone progesterone is usually produced in the body and has the primary function of thickening the uterus lining and preparing it for pregnancy. Miscarriage and low progesterone levels are inter-related. But there is no clarity regarding the relationship between progesterone levels and miscarriage. This article aims to shed light on this issue so that you will be able to decide if you should take progesterone supplements or not.
As per research, taking progesterone supplements during pregnancy cannot prevent the occurrence of a miscarriage, even in case of a threatened miscarriage. However, a research study mentions that it is imperative to take progesterone supplements when the pregnancy results from some sort of assistive method such as In Vitro Fertilisation (IVF).
Is Low Progesterone During Pregnancy Associated With Miscarriage?
When the uterus is unable to support the growing foetus for some reason, the level of progesterone drops, and it results in a miscarriage. Other theorists believe that even if the body is about to terminate a pregnancy due to reasons such as chromosomal irregularity in the foetus, it can lead to a low progesterone level, and this is a sign of the impending miscarriage. In such a case, progesterone supplements are useless.
Some practitioners, from clinical experience, believe that in the case of recurrent miscarriages, progesterone supplementation has lead to a successful pregnancy. Progesterone supplementation may also be suggested to those women who have low levels of progesterone. Supplemental progesterone has a chemically identical structure to the progesterone that the body generates. So, many practitioners prescribe it anyway, by justifying that it won’t harm as it is only a supplemental hormone that the body is already producing.
Can Progesterone Prevent Miscarriage?
Earlier, physicians routinely prescribed a drug known as DES to women with the idea that it prevents miscarriage. But later, it was found that the use of this drug resulted in abnormalities in children born to the mothers who took it. Though several physicians currently feel it is safe to use progesterone, there is no proof for the same.
Studies conducted by the New England Journal of Medicine have shown that progesterone does not really help in preventing miscarriage. The 2015 study looked at several women who had miscarriages due to several reasons. Progesterone supplementations did not result in more live births. However, several moms claim that the additional progesterone supplements helped them to stay pregnant after repeated miscarriages. Thus, the role of progesterone in preventing a miscarriage is highly debatable.
A threatened miscarriage is when a mother-to-be loses her baby within 20 weeks of gestation. Studies have shown that progesterone is beneficial in reducing the rate of miscarriage. However, the rate of threatened miscarriage has not decreased drastically with the use of progesterone.
When Is Progesterone Treatment Recommended?
Some doctors suggest progesterone injections during pregnancy to prevent miscarriage, as an increased level of this hormone is required in the body to sustain the pregnancy.
The following are the cases when your doctor might recommend progesterone supplementation:
- When you have undergone fertility treatments, progesterone supplementation will keep your estrogen and progesterone levels in balance.
- When you have undergone a frozen embryo transfer, it helps prevent a corpus luteum from being formed.
- History of repeated miscarriage without a cause.
- History of preterm labour.
- Presence of a cervix that is shorter than normal.
Progesterone in early pregnancy is necessary to prevent miscarriage. However, if the level of progesterone drops, the uterine lining might not be able to carry the pregnancy, and it will result in a miscarriage.
How Is Progesterone Given?
Progesterone treatment is administered either by injection or vaginally. However, it is believed that injections are more effective than vaginal suppositories. The upper area of the buttocks is the preferred site for giving injections. But, if you have to administer it yourself, then you should go for the upper thigh region.
Side Effects of Taking Progesterone to Prevent a Miscarriage
Common side effects of injecting progesterone are:
- Redness, swelling, or pain on the body part where the injection was administered.
- Hardness or itching around the body part where the injection was administered.
Following are the side effects of progesterone (when taken in another form):
- Fluid retention
- Breast tenderness
- Nausea or diarrhoea
- Irritability or depression
Are There Any Serious Reactions?
A major side effect of progesterone is the formation of a blood clot. However, you should consult a doctor immediately, if you notice any of the following signs too:
- Swelling in legs
- A warm spot in the leg
- Pain while bending the leg
Although progesterone allergy does not occur, you might be allergic to substances used by the manufacturer to make the solution, such as cottonseed oil. In case you notice rashes, itching, redness at the injection site, or if you experience any difficulty in breathing, seek professional help immediately.
The subject of progesterone is a tricky one. No one can say for sure whether or not progesterone contributes positively, especially in the case of women who have had multiple miscarriages in the past. If you still want to take progesterone, talk to your physician and see if there are any viable alternatives.
The above article does not intend to promote or demote the usage of progesterone supplementation during pregnancy. The reader is advised to seek a doctor’s opinion before taking any sorts of supplementation.
