Female Factor infertility has many causes --Poor development of inner wall of womb : Poor Endometrial thickness is not an uncommon case of infertility. Its causes & Treatment.

There are many causes of female factor infertility. One of the common causes is under development of inner wall of womb (uterus). Doctors call the inner wall as endometrium and it most importantly is this place where from monthly cyclical bleeding occurs as menstruation. Thickens of inner lining of womb is assessed by repeated sonography though occasionally some serum markers are evaluated in research settings where question of receptivity of endometrium is evaluated in details. What is the usual / normal thickness of endometrium?

At the beginning of menstrual cycle such inner wall of womb is about 3-5 mm as imaged by sonographic machine –often called Ultra or ultrasonography...

In normal fertile women (healthy women) the inner wall achieves a thickness of about 8-12 mm. as imaged in ultrasonography. Ultrasonography is the main means OF DIAGNOSIS or marker of poor development / growth of thickness of inner lining of womb.  As mentioned it is this important place where a fertilized egg gets attached and get nutrition to achieve normal sped of growth and finally developing from embryo—Foetus. If inner wall of womb is poorly developed-(this called by the infertility specialists as - thin endometrium-,). ET means endometrial thickness.

Besides thickness there can be qualitatively endometrium can be suboptimal. In such an event endometrium may be of normal thickness as evidenced by or poor in functional competency to supply nutrition. But this may elude the doctor as thickness is adequate. This functional inadequacy is termed by fertility specialists as unreceptive or hostile endometrium by the scientist).

Conclusion:-It is, therefore understandable that if ET do not grow in thickness properly or develops as per expectation but functionally remain poor (difficult to substantiate by conventional Lab tests) in such women   the fertilized egg (Blastocyst –formed after meeting of egg and sperm) can either unable to get either attached to womb or even if attached will be unable to grow-further leading to infertility problem or early abortion. In such event the possibly the phenomenon of abortion usually remain unknown to woman concerned. The description that follows is threadbare description of causes of poor development of inner wall of womb (uterus) and related infertility problem.aa
