Endometrial Thickness – What’s Normal Range for Pregnancy


For a body to get pregnant, a number of things need to fall into place at the right time and be in the right condition for conception to be successful. Fertilization is just the tip of the iceberg and there are a ton of processes that take places involving your uterus and the menstrual cycle that ensure that the egg stays secure. One of the key aspects in that regard is the endometrium and the thickness of its wall.

What Is Endometrium?

The uterus has a lining towards the inner side of its wall, made up of mucous membranes. These altogether constitute the endometrium. There are two layers that build it up. One is the functional layer, which is the one that sheds itself during each menstrual cycle. The other layer is the base and continues to remain on the uterus forever. Depending on the menstrual cycle, the thickness of the endometrium keeps changing.

What Is Normal Endometrial Thickness For Pregnancy?

As a general comparison, the endometrium layer is in itself pretty thin. Towards the end of the menstrual cycle, when the upper layer has been shed completely, the layer that remains is barely as thick as 1mm. As the next ovulation cycle begins, the cells start creating the new functional layer above it.

The layer usually varies from person to person but endometrial thickness normal range for conceiving is usually considered to be around 8mm, which needs to go up to around 15mm to be able to hold the fertilized egg securely.


What Causes Thin Endometrium?

A thin endometrium may be caused due to several reasons.

1. Poor blood flow

If the uterus does not receive an adequate supply of blood, it may have trouble creating an endometrium that is thick enough for conception. Lack of adequate blood flow may be due to a tilted uterus, uterine fibroids or even a sedentary lifestyle.

2. The Wrong Pace Of Endometrium Growth

On a general basis, it has been observed that any thickness less than 6mm can prevent conception from being successful. However, even at 8mm thickness, if the growth of the endometrium layer is not at the pace as it should be, that could still cause the conception to fail.

3. Estrogen-Related Issues

Reduced levels of estrogen could sometimes result in not causing the cell growth and thickening of the endometrium layer to be at the pace as needed.

4. Improper Functioning Of Progesterone

Progesterone hormones, too, could not function in the manner as they need to, resulting in a thin endometrium.


5. Side Effect Of Fertility Drugs

In a cruel twist of irony, certain drugs that are used to boost fertility and trigger ovulation might inadvertently cause a side effect that results in thinning of the endometrium layer.

6. Stressful Lifestyle

The absence of enough rest and sleep could result in stress, which prevents the optimal growth of the endometrium layer.

Ways To Increase Endometrial Thickness For Conceiving

You can help in the improving the thickness of your endometrium to make it apt for conception.

1. A Good Diet

Consuming a diet that is balanced and nutritious affects the levels of estrogen, maintains a balance of hormones, and provides a boost to the blood flow. All of these factors together help in assisting the growth of ideal endometrial thickness for pregnancy.

Consume meals throughout the day to keep levels of insulin and cortisol at a healthy level. Include fibre in the diet as well as food items that have the Q10 coenzyme. This is a powerful antioxidant that reduces tissue related stress which helps cultivate a thick endometrium.

Items like green leafy vegetables, tomatoes, eggs, carrots, fish, and so on contain all the important vitamins such as vitamin C and vitamin E along with the B-complex group which are all necessary for a healthy blood circulation.


Cut down on sour food items as well as caffeine to improve your health.

2. Enough Rest

Having good rest and a deep sleep brings about a good balance of the hormones, which affect the thickening process of the hormones. Deep sleep of at least 7-8 hours is essential for the body to conduct its repair activities and undertake tissue growth optimally. Maintain a schedule of waking up and sleeping at the right time on a daily basis, without staying awake for long hours and late nights.

3. Regular Exercise

The natural way to boost blood circulation is by having regular exercises. The increased supply of blood to the uterus also assists in the growth of the endometrium cells, which also increases its thickness.

Extensive exercises are not needed. Spending about half an hour every day should suffice. Keep a variety in the forms of exercise to prevent yourself from being bored and keep a balance in activities, too. Exercises also help you in attaining a deep sleep at night, assisting in growth.

4. Massaging The Femoral Artery

A proven way to boost the supply of blood towards the uterus and the pelvic region of the body is by stimulating the femoral artery. Using your fingers to gently apply pressure on the artery for a few seconds helps achieve that.

This should be usually done following the end of the menstruation cycle until ovulation occurs. By repeating it thrice on each leg for a couple of times in a day, it ends up being quite beneficial in assisting endometrium growth.

In cases of IVF or high blood pressure symptoms, massaging the artery should be avoided.

5. Acupuncture

The alternative therapy of acupuncture is known to provide a lot of relief to pregnant women as well as streamline timely delivery. In a similar fashion, it also helps in restructuring the blood supply within the body, which provides a boost to the fertility.

6. Castor Oil

Ricinoleic acid is a chemical that is known to increase the flow of blood and boost healing as well as the formation of tissues. This particularly affects the ovaries and the womb as well. This acid is found in castor oil and making use of it can be quite beneficial.


1. How Much Endometrial Thickness Is Too Much?

As thin endometrium is a problem, an endometrial layer that is too thick can just be an issue. Endometrial hyperplasia is the medical term to define this condition, which usually occurs due to excessive estrogen levels. This is where the layer gets thicker than even 10-15mm.


2. Is It Possible To Get Pregnant With An Endometrial Thickness Of 5 Mm?

5mm is too thin to be able to get pregnant or even sustain a pregnancy. Ovulation induction might be required along with progesterone supplements.

The right endometrial thickness for conception is an essential component in the entire process of getting pregnant and staying so. Adhering to healthy lifestyle choices and adopting proper treatment procedures to take care of the condition, can help your body become a great housing for your potential baby.
