Did you know the lining thickness of a woman’s uterus is crucial for a successful IVF?

Also known as the endometrium, this is where the embryo implants at the beginning of the pregnancy and continues to develop. Every month, when the ovaries release an egg, the uterine lining thickens in size in preparation for embryo implantation. If egg fertilization does not happen, then the lining sheds itself and gets expelled by the body in the form of menstrual blood.

If you are undergoing IVF treatment, your fertility doctor will usually measure the thickness of the uterine lining to ensure that it is adequately thick enough for implantation to occur. This is because the uterine lining is rich in nutrients and provides steady sustenance for the embryo to grow healthily. The ideal thickness of the lining is at least 7mm to 8mm with a trilaminar (three layered) appearance on an ultrasound. A uterine lining that is too thin is not the ideal environment for the embryo, as the embryo may fail to attach properly to the lining and lead to early pregnancy loss.

A woman may have a thin uterine lining for several reasons, the main reason being a deficiency in estrogen, poor blood circulation in the uterus, uterine fibroid, chronic endometriosis (inflammation of uterine lining), hydrosalpinx (blockage of a woman’s fallopian tube), and scar tissues in the uterus.

A thin uterine lining needs to be fixed before a couple tries to conceive. A thick uterine lining is important to sustain a growing fetus. Although it is possible to conceive with a thin lining, your fertility doctor may suggest improving and thicken your lining before the embryo transfer happens.

In many cases, most women are unaware that their uterine lining is thin, as this issue may have been going on for a long time before a woman decides to get pregnant. Proper testing is required to determine this, however, some noticeable signs of a thin uterine lining may be abnormal and painful periods, as well as problems with carrying a baby to full term.

These are tried and tested routines that encourage the growth of your uterine lining to improve your chances of having a successful IVF treatment.

Estrogen Supplements

Estrogen plays an important role in reproduction, and low estrogen levels can sometimes lead to a thin endometrial lining. Estrogen supplements introduce extra estrogen into the body from outside and promotes endometrial lining growth. These supplements can come in the form of patches, oral pills or suppositories.

Physical Exercise

A good supply of continuous blood flow is necessary for the healthy growth of the uterine lining. If you are not previously active, you should engage in regular exercise to improve blood flow. Low to moderate-intensity exercise will do, as high-intensity exercises are not recommended for women who are trying to conceive.

Acupuncture has been shown to improve fertility in both men and women in several medical studies. Acupuncture increases blood flow to the uterus, improves ovary function, and balances the hormones in the body. This is the key reason why acupuncture has been included in many modern-day fertility treatments.

Quit Smoking and Drinking Coffee

Caffeine and nicotine can impede blood flow in the body and affect blood circulation. If you are able, quit smoking and caffeine entirely. If that’s too challenging, try to cut back on your consumption.

Maintain A Healthy BMI

Women with a low BMI may find it more difficult to conceive because fat cells are responsible for producing extra estrogen in the body. Consider working with a nutritionist to reach your ideal BMI weight, which is usually in the range of 18.5 to 24.9.

There are plenty of fertility treatments available in the market today, and you should speak to your fertility doctors for more advice.
