FSH Level during Pregnancy

FSH (Follicle Stimulating Hormone) Levels in Pregnancy

A woman’s hormonal levels keep fluctuating. One such hormone that all women should know about is the ‘Follicle Stimulating Hormone’ (FSH). Here we discuss the follicle-stimulating hormone in detail. An FSH test is done before conception while treating infertility.

What Is FSH and What Is Its Role Before 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.

What Is the Ideal FSH Level?

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

What Conditions Lower the FSH Level

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.
  • 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

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 throughout the day.

There are no certain steps to be followed before reporting to an FSH test. You would not be asked to stop taking fluids or food, unlike in other tests. 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.

Here is a list of frequently asked questions that are associated with taking the FSH test:

1. Are there any special precautions to be taken post the test?

There is no separate precaution to be taken after the FSH test. In case of dizziness or discomfort during or after the test, make sure you ask for support and take a seat at a comfortable place.

2. Are there any side effects of taking the FSH test?

The FSH test is one of the safest tests and has no documented side effects. Very few cases have been reported where a person has encountered dizziness or slight discomfort. If you do, let your medical practitioner know about it.

The easiest way to appreciate the significance of any test that you are referred to is by having a word with your doctor. Request your doctor to explain the reason you have to take a particular test and what the results indicate.
