Overview
The endometrium plays an essential role in achieving success during an IVF cycle. The endometrium should be receptive for a successful pregnancy. Doctors suggest various ways to improve endometrial thickness for IVF success. A combination of lifestyle changes, diet, exercise, and medical methods can help effectively improve endometrial thickness. In this article, we will discuss the causes of thin endometrial lining, natural measures, and medical options to increase endometrial thickness.
What is Endometrial Thickness?
Endometrial thickness is the measurement of the uterine lining, commonly measured through ultrasound. A thick and healthy endometrial lining is important for successful embryo implantation.
The endometrium is the inner membrane that lines the uterus. The primary function of this lining is to thicken during each menstrual cycle to prepare for pregnancy. If fertilisation occurs, the embryo implants in this layer to receive oxygen and nutrients for further growth. If pregnancy does not take place, the lining sheds during periods.
Importance of Thick Endometrium
A thick endometrium is essential for IVF because it provides a suitable environment for embryo implantation and further growth. A healthy endometrium supports the implantation and provides nutrients to the embryo for further growth. The thickness of the endometrial lining directly impacts fertility outcomes in natural as well as assisted reproductive treatments such as IVF.
The normal range of endometrial thickness is between 8 and 12 millimetres, which is considered suitable for embryo implantation. Estrogen plays a vital role in the development of a thick, blood-rich endometrial lining. An imbalance of hormones or estrogen can cause a thin endometrium, making implantation unsuccessful.
What Are the Causes of Thin Endometrium?
A thin endometrium is considered if it is less than 7mm during the mid-luteal phase of the menstrual cycle. The leading causes of thin endometrium include:
- The most important cause for a thin endometrium is low estrogen levels. Estrogen is important for building a soft and receptive lining. Low estrogen levels occur due to prolonged use of birth control pills or ovulation-inducing drugs.
- Age is another factor that contributes to a thin endometrial lining because of increasing age imbalance hormones, and the lining may not develop properly.
- Structural abnormalities such as fibroids, polyps, uterine adhesions, or endometriosis can alter the structure of the uterus and affect blood supply to the endometrium, disrupting the healthy regeneration of the lining.
- In some cases, scarring from previous surgeries or infections can also reduce the endometrium's ability to rebuild during each menstrual cycle.
- Thin lining may occur due to inadequate blood flow to the uterus. A thick endometrium grows when there is proper blood flow to the uterus. Due to poor blood circulation, the endometrial lining becomes less receptive.
- The blood supply to the uterus may also be affected by stress because the body's response to stress is to release hormones that reduce blood flow to the reproductive organs, causing a thinner uterine lining.
- Lack of the necessary amounts of vitamins and minerals during each menstrual cycle can have an impact on the development of the new endometrial lining.
Natural Methods to Increase Endometrial Thickness for IVF
There are many ways to increase the thickness of your uterine lining for IVF naturally. Natural ways are:
- Exercise is an important part of improving blood circulation; this improves your ability to create a healthy uterine lining. By doing things like stretching, jogging and walking for 30 minutes a day, it's possible to improve blood flow to reproductive organs, making them healthier, and develop a thicker uterine lining.
- Relaxation is a great way to ease both your muscles and uterus. This can be accomplished by doing some form of relaxation therapy like deep breathing, yoga, and guided meditation. These therapies also calm your mind to support hormonal balance and the formation of a receptive endometrium.
- Sleep for at least seven to eight hours daily for body tissue repair, hormone regulation, and improvement of reproductive function.
- Drink enough water throughout the day to stay well-hydrated, as dehydration can reduce blood flow. Follow a balanced routine, eat proper meals on time, and stay relaxed throughout the day to maintain hormonal balance.
- Gentle pelvic massage can also help improve blood flow to the uterus, thereby increasing endometrial thickness. You can also use castor oil to apply on the abdomen during the day 5-14 when trying to get pregnant.
Important Nutrients to Increase Endometrial Thickness
A healthy diet supports the growth of a healthy endometrium. Some nutrients balance hormones, help in cell generation, and improve blood flow.
- Foods rich in iron are necessary because iron improves blood flow and helps to prevent thinning of the endometrial lining. Lentils, spinach, pumpkin seeds, beetroot, and lean red meat are good sources of iron.
- Whole grains can help to balance hormones and improve endometrial thickness. Therefore, add quinoa, oats, brown rice, and bread to improve metabolic functions and hormone levels.
- Vitamin C is essential for iron absorption. It also supports tissue repair. You can add tomatoes, citrus fruits, broccoli, and strawberries to get enough vitamin C.
- L-arginine is important to consume as it helps to increase endometrial thickness. It is found in whole grains, fish, soy, poultry, and dairy products.
- Omega-3 fatty acids improve blood flow and reduce inflammation. It also helps to make the lining more receptive. It is found in walnuts, salmon, flaxseeds, and mackerel.
- Fruits that support nitric oxide production are good for increasing the thickness of the endometrium because nitric oxide dilates blood vessels and improves blood circulation to the uterus. Lemon, lime, and pomegranate produce nitric oxide.
- Coenzyme Q10 helps to reduce oxidative stress and promotes the formation of a healthier uterine lining.
- Vitamin E is an excellent source of antioxidants and supports cell growth, and improves estrogen levels.
Medical Methods to Improve Endometrial Thickness
Natural methods can be combined with medical methods if natural methods are not enough to increase endometrial thickness. The doctor may choose the correct medical treatment based on hormone levels, previous history, and uterine condition.
- A doctor may prescribe estrogen therapy if the endometrium does not grow due to low estrogen levels. Proper monitoring is necessary to assess the response and balance progesterone and estrogen.
- Low-dose aspirin may be given to improve blood flow to the uterus and reduce the risk of clotting.
- Sildenafil citrate may be given to improve blood flow and oxygen to the uterus. It is given in the vaginal form to increase endometrial thickness.
- Gonadotropin agonists are prescribed to trigger a brief aggravation of hormone release and stimulate estrogen production for endometrial growth.
- Fertility experts may administer human chorionic gonadotropin hormone directly to the uterine cavity to stimulate growth factors and improve blood circulation. It is used in cases with recurrent implantation failure.
- Platelet-rich plasma therapy is an advanced technique in which plasma is extracted from the patient’s own blood and infused into the uterus to promote cell regeneration, improve blood flow, and stimulate endometrial growth.
Conclusion
Having a healthy endometrium is essential for the successful implantation and continuation of pregnancies conceived through in vitro fertilisation (IVF). It is the base for embryo implantation and growth, as it provides nutrients and blood supply to the growing embryo. A thin endometrium may occur due to low estrogen levels, poor blood supply, stress, and lifestyle factors. Timely medical care, dietary modifications, and lifestyle changes can help reverse the condition and achieve success. Advanced science offers different medical treatment options that can help restore the endometrial lining growth for effective embryo implantation.
