Introduction:

A follicular study scan includes other evaluations besides monitoring your follicle size.

One such study involves studying the thickness of the endometrium lining (ET).

What is Endometrial Lining?

The endometrium is the inner lining of a woman’s uterus. It is one of the few organs that keeps changing in size according to a  woman’s fertile days.

Every month this endometrial lining keeps changing along with the menstrual cycle. Its thickness varies in response to your body’s reproductive hormones – estrogen and progesterone.

Sometimes, the endometrial lining is abnormally thick or thin, impacting your ability to become pregnant or causing irregular bleeding during periods.

What Is The Use Of Endometrial Lining?

Before the release of an egg (ovulation period), the functional layer of the endometrium goes through specific changes.

The inner lining of the uterus starts to thicken and prepares itself to host an embryo (fertilized egg) and support the placenta in case of pregnancy

If conception doesn’t take place after ovulation, this endometrial lining sheds itself in the process known as Periods (Menstruation).

Why ET measurement is important?

A healthy endometrium is very important for a healthy pregnancy.

It should be neither too thin nor too thick for a successful pregnancy.

A follicular study will assess both the follicle size and the endometrial lining.

It is essential to check for thickness, as the lining of the uterus should match the size of the follicle to accept the pregnancy.

If the endometrium lining is thin (i.e. the follicle is ready to rupture, but the uterus lining is thin), this is not favorable for getting pregnant.

What Should Be The Size Of ET in Follicular Study To Get Pregnant?

For a successful pregnancy, an endometrial thickness of around 8 -10mm is considered the best during your follicular study.

This level of thickness makes it good enough for the embryo to implant and receive the nutrition it requires.
