FSH (Follicle Stimulating Hormone) Levels in Pregnancy

FSH (Follicle Stimulating Hormone) Levels in Pregnancy

During pregnancy, a woman’s hormonal levels keep fluctuating. A woman’s body undergoes these changes to protect the newly formed foetus, aid lactation, and for the proper functioning of other organs during pregnancy. One such hormone that all pregnant woman should know about is ‘Follicle Stimulating Hormone’ (FSH). Here we discuss follicle stimulating hormone and pregnancy in detail.

What Is FSH and What Is Its Role in Pregnancy?

Follicle stimulating hormone is secreted by the pituitary gland. Its primary function is to stimulate ovaries to produce mature eggs for fertilisation. It is also the hormone responsible for facilitating a regular menstrual cycle. Let us understand the significance of FSH and its meaning in pregnancy.

What Is the Ideal FSH Level during Pregnancy?

A vital role played by FSH during pregnancy is that it helps in the formation of the placenta in the initial months. The normal range of FSH in pregnancy is between 3-10mIU/ml (milli-International Units per millilitre). However, in the initial stages of pregnancy, it will be at 2mIU/ml.

What Does Low FSH Level Mean?

The levels of FSH during pregnancy remain relatively low during pregnancy. If the levels are lower than the indicative normal range, then it could be demonstrating one of the following conditions:

1. Hypopituitarism

This is a condition in which the pituitary gland does not produce certain hormones that it should produce. Sometimes, it may be producing them in very minuscule quantities.

2. Turners Syndrome

This is a consequence of reduced FSH levels. It is a chromosomal condition that affects growth and development, like height and ovary development, in females.

What Conditions Lower the FSH Level in Pregnancy?

Following are the conditions that may lower your FSH levels:

  • Anorexia nervosa, an eating disorder characterised by uncharacteristically low body weight, can lower FSH levels considerably in pregnancy.
  • Disorders related to the hypothalamus, located at the base of the brain, can also reduce FSH levels.
  • Malfunction of the pituitary gland also reduces the production of FSH in the body.

How to Prepare for the FSH Test while Pregnant

There are two methods by which your doctor will check your FSH level. The following two tests will be performed.

1. Blood Test

A medical professional would make use of a needle to draw a slight amount of blood for use from a visible vein. This may cause mild discomfort, but it is a quick process.

2. Urine Test

The medical professional will ask for a single urine sample or more than one across a 24-hour period. This method gives an accurate view of your FSH level, which varies through the day.

There are no certain steps to be followed before reporting to an FSH test in pregnancy. You would not be asked to stop taking fluids or food, unlike in other tests. You can continue following your normal pregnancy diet. Consult a medical practitioner and understand what preparation is required before taking the test. You may be advised to stop some or all of your medications 48 hours preceding the test.
