  • A salutary and thick endometrium is crucial for a successful pregnancy and a regular menstrual cycle. 
  • Healthy Endometrium ensures effective fertilized egg implantation inside the uterus,
  • Estrogen and progesterone hormones help in maintaining the desired endometrial thickness.

Some women have a thin endometrial lining, a common factor contributing to infertility in females. Numerous studies have proven that if a woman has a thin uterus lining, then the chances for successful natural pregnancy and positive signs after the embryo transfer are reduced.

We here discuss the normal thickness of the endometrial lining during the menstrual cycle, finding out the relatable causes, symptoms, and treatment for successful pregnancies. 

 What is Normal Endometrial Thickness?

 A thin endometrial lining cannot cultivate the eggs and hold them, increasing the chances of recurrent IVF failures. The reason for declining uterine lining thickness is either the menstrual cycle phase or hormonal imbalance.

The normal uterine thickness

  • During the menstrual cycle, the size is 2-4mm,
  • Increase to 5-7mm during the follicular phase,
  • Size is 7-11mm during the ovulatory phase
  • Size goes up to 16mm after ovulation.

“Lining below 8mm is associated with implantation failure, low pregnancy rates, and poor receptivity, considered as thin endometrium. And if the lining is less than 5mm, then there are zero chances of pregnancy. Endometrial or uterine lining thickness is a beneficial predictor for pregnancy success and embryo implantation It is measured through ultrasound during IUI, IVF, cycle monitoring, and frozen embryo transfers” .-Knowing this the experts at IVF CLINIC  first identify the real cause of Infertility and the recommend the treatment. 

 What are the Reasons for Thin Endometrium?

 The 5 causes of thin endometrial lining are:

  1. Low Estrogen

 A woman with a thin endometrial lining is usually diagnosed with low estrogen levels, the only hormone responsible for the thickening of the endometrium. Therefore, medication with oestradiol is prescribed to maintain desired estrogen levels, and the response is monitored.

 If there are no changes in the lining even after medication, this indicates poor or inadequate blood supply. Lesser physical workouts and uterine wall tissue damage can be the reasons.   

  1. Inadequate Blood Flow

 Sometimes, blood flow to the endometrial lining is restricted, leading to thin endometrium. There can be multiple reasons for restricted blood flow, varying from the tilted uterus to a sedentary lifestyle, fibroids, and polyps, causing the endometrial lining to shrink.

  1. Fibroids and Myoma

 Fibroids and Myoma are the thin layers of smooth muscles present in the uterus. But, 10-20% of women’s bodies tend to develop into thick muscles that further hinder epithelial lining growth.

 The muscles initially develop on estrogen found in uterus linings. The muscles are too small to be detected by the naked human eye and too big to cause bulges in the uterus. Doctors usually recommend surgery to remove the fibroids, clearing the path for implantation. 

  1. Damaged Endometrial Lining

 There are some cases when the estrogen levels are found normal in women’s bodies, but they still face complications in embryo implantation.

 A damaged endometrial lining can be the reason for it which can cause the formation of scar tissue. This damage can be due to a previous bacterial infection, and surgery is recommended to remove the undesired scar tissue from the uterus.

  1. Chronic Endometriosis

 Chronic Endometriosis can also be the reason for the thin endometrial lining. Painkillers and hormone therapies are recommended to ease the symptoms.

 The disease is not life-threatening but can hinder daily lifestyle and workings. Therefore, fertility experts recommend the course of antibiotics to get it treated as soon as possible. 

Symptoms for Thin Endometrium: 

Studies have shown that 30% of women do not experience any symptoms directed to thin endometrium. They have got it diagnosed in the ultrasound conducted for their IVF Treatment. 

 The rest of the women who have faced some common symptoms of thin uterine lining are: 

  • Irregular Periods:

 One of the most common symptoms of thin endometrium in a woman is an irregular menstrual cycle. The timing for the menstrual cycle usually differs every month in the case of the thin endometrial lining. 

However, it is recommended not to jump to any conclusions without clinical advice. Consult a doctor to know the reason and ideal treatment for the issue. 

  • Fertility Issues

Thick and healthy endometrium is essential to carrying out a successful pregnancy. Therefore, it is an important aspect needed for healthy egg implantation and fetus growth. Women with thin endometrium problems are also diagnosed with fertility problems. 

  • Painful Menstruation

 Along with irregular periods, you might also experience painful periods due to thin endometrium. Consult your gynaecologist for the treatments if it continually grows with every cycle. 

  • Inadequate Bleeding during Periods

 Another common symptom of thin endometrium is short periods associated with inadequate bleeding. The endometrial lining is too thin to shed off and contains lesser tissues released during the cycle. 

What Are the Treatments for Thin Endometrial Lining? 

Depending on the cause of thin endometrium, there are different treatments proposed by fertility experts. Doctors will run different tests and diagnoses to finding out the reasons and factors behind the issue, providing easy answers for how to increase the thickness of the endometrium! 

Some of the best and most recommended uterus lining thin treatments with higher rates of success are:
