Struggling to Conceive? Thin Endometrium Could Be the Culprit: Symptoms to Watch
Thin Endometrium Explained: The endometrium is the innermost lining of the uterus that plays a crucial role in the reproductive process. Every month, the endometrial lining thickens in preparation for receiving a fertilized embryo, and if no pregnancy occurs, it sheds during menstruation. However, if the egg gets fertilized, the endometrium undergoes changes to create a hospitable environment for the embryo to implant and grow. A healthy endometrial lining is vital for a successful pregnancy. An ideal endometrium has 8mm thickness, is echogenic (appearing bright on ultrasound), and has a rich blood supply.
In this article, Dr. Kaushal Kadam, MBBS, MD, DGO and Director, Corion Fertility Clinic Pvt Ltd., tells us more about thin endometrium and how it affects a woman's fertility.
Thin endometrium refers to a uterine lining that is thinner than normal, typically less than 7 mm. A thin endometrial lining may decrease pregnancy rates, especially in In Vitro Fertilization (IVF). Studies indicate that an endometrial thickness of less than 7 mm can reduce the pregnancy rate by 60%. Moreover, when the endometrium measures less than 5 mm, the live birth rate is significantly reduced. A few pregnancies have been reported with 4mm endometrial lining, but these are considered extremely rare and are usually complicated.
The main causes of thin endometrial lining are hormonal imbalance, poor blood supply to the uterus, and infections such as Endometrial Tuberculosis. It poses a problem while trying to conceive and is often involved in repeated miscarriages.
Most women have no clinical symptoms until it is time for conception or till they undergo fertility studies. Some symptoms suggestive of a thin endometrium are as under:
There are many causes of the thin endometrial lining, such as hormonal imbalance, age, infection, and some medical procedures. However, the most common causes are as follows:
There are several treatment options available for women diagnosed with a thin endometrial lining. The specific treatment will depend on the underlying cause, and your physician will guide you toward the best option. Certain lifestyle changes can also help improve endometrial thickness:
Regular physical exercise, especially yoga or light cardio, improves blood circulation to the uterus. Massage and techniques such as reflexology may also help promote uterine health.
Maca root, Ginseng, and Vitamin E are thought to enhance endometrial thickness through the stimulation of estrogen levels and enhancement of blood flow to the uterus. All supplements should be discussed with a healthcare provider before taking them.
Platelet Rich Plasma is a rich concentrate of growth factors and platelets obtained from patient's own blood. These have shown to have a favorable impact on the endometrial receptivity by improving blood flow to the uterus and endometrial thickness. In PRP therapy, the patient's blood is drawn, enriched with platelets and injected back into the uterine to stimulate a new generation of the endometrial lining with better thickness.
In the case of poor endometrial thickness, estrogen therapy for some time in the form of oral tablets, vaginal pessaries, or transdermal creams help to stimulate growth of endometrium. .
In the case of adhesions and scarring, hysteroscopy (placing a camera into the uterine cavity) can be done to diagnose and treat adhesions, remove scar tissues, to improve the chances of successful implantation.
A thin endometrial lining can be frustrating for women when they are trying to conceive through assisted reproductive methods like IVF. Hormonal imbalances, age, infections, or previous medical procedures are some of the major causes for it. Several treatments are now available to address this condition, including medication, lifestyle changes, and advanced therapies such as PRP. If you have a thin endometrium, it is crucial to work you up with a fertility specialist who can help tailor the right treatment plan for you and give you the best chance at a successful pregnancy.
