Thin Endometrium & its importance in Infertility

What do you mean by thin endometrium or thin lining of uterus?

For an embryo to implant in endometrium, it should be thick, receptive & nourishing. Endometrial thickness of 8mm or more than 8mm is considered normal for successful implantation and a thickness of less than 7mm is thin endometrium which decrease chances of successful pregnancy.

Thin Endometrium its importance in Infertility

Symptoms of Thin Endometrium:
• Low menstrual bleeding.
• Irregular menstrual cycle.
• Painful menses.
• Infertility.
• Without any symptoms & diagnosed in ultrasound scan.

Causes of thin Endometrium:
• Reduced blood flow to the uterus.
• Infections like Endometrial T.B., pelvic infections.
• Reduced estrogen level.
• D&C or any other surgeries leading to adhesions or scarring.
• Use of oral conceptive pills.

Treatment options:
First & foremost is ultrasound to check the thickness of endometrium.

• Hysteroscopy: To diagnose & remove any scar tissue or adhesions in uterus
• Infections like endometrial T.B. or any pelvic infections should be treated with medicines.
• Estrogen therapy: Estrogen hormone is vital in keeping the endometrium thick. So, patients are given Estrogen supplements to increase thickness of endometrium.
• Some newer technology like PRP (Platelet Rich Plasma) therapy, endometrial scratching seems to increase thickness of endometrial lining.
• If during an IVF cycle it is found that a patient has poor endometrium. We freeze all her embryos in that cycle & transfer later once the endometrium has thickened & ready to accept the embryos.
