Follicular-Stimulating Hormone (FSH) Test
The Follicle-Stimulating Hormone
(FSH) test is a blood test that measures the level of FSH in the bloodstream
which plays a crucial role in regulating the menstrual cycle in women and
supporting sperm production in men. FSH is produced by the anterior pituitary
gland in the brain. In women, the FSH test is used to asses and monitor various
aspects of reproductive health and helps in diagnosis of conditions such as
infertility, irregular menstrual cycle, PCOS, and menopause. In men, FSH test
is often carried out to assess and diagnose conditions such as hypogonadism and
infertility.
Overview of the Key Factors of FSH test:
Importance of the levels of FSH:
FSH levels generally vary
throughout the menstrual cycle in females and are typically higher just before
and during ovulation and lower in the early and mid-follicular phase. FSH
levels are typically stable in men but higher than normal levels can indicate a
testicular problem. Elevated FSH levels in women can indicate a diminished
ovarian reserve, menopause, or other ovarian conditions or may be linked to
hypothalamic or pituitary issues. During the follicular phase, normal FSH
levels in females is usually between 4.7 to 21.5 IU/L and during the mid-cycle
or ovulation, the levels of FSH go lower; often below 10 IU/L. In men, the
normal range of FSH is between 1.5 to 12.4 IU/L.
Procedure:
●
There are no specific preparations needed before test ;
however it is important for the patient to follow any instructions given by the
healthcare provider.
●
Patients are advised to wear loose fitting clothing
with sleeves that can be easily rolled up.

collected with an antiseptic solution.
●
A tourniquet will be tied to the arm of the patient and
a needle will be inserted into the vein in the arm.
●
The blood sample will be drawn into specific tubes
labelled with accurate patient data.
●
The needle is then removed and a bandage will be
applied to the site of venipuncture to stop from further bleeding or infection.
●
The blood samples will then be sent to the laboratory
for analysis of FSH levels.
●
The results are usually available in a few days and the
healthcare provider will interpret them taking into consideration clinical
history and reason for the test of the patient.
●
Healthcare providers will then decide if additional
tests are needed or if treatment should be taken.
Benefits:
●
Relatively safe, quick, and painless procedure
●
Provides accurate assessment of ovarian reserve
●
Helps in comprehensive assessment of menopause and
plays an important role as a guide in determining symptom manager and treatment
●
Helps in accurate diagnosis of ovarian diseases such as
primary ovarian insufficiency or premature ovarian failure
●
Helps in accurate evaluation of testicular function in
men
●
Assists in guiding timings for fertility treatments
such as IVF
●
Helps in monitoring treatment effectiveness in patients
undergoing hormone replacement therapy
Precautions to be taken for FSH test:
Patients must inform their
healthcare providers about any medications or supplements that they are taking
since some drugs can affect the levels of FSH in the blood. The healthcare
provider might advise you to stop certain medications to ensure accurate results
are obtained. Patients must remain calm and relaxed during the tests as stress
can interfere with the levels of FSH. Patients must wear comfortable clothing
during the test to ensure maximum convenience during the testing. Patients must
consult their health care providers for any specific instructions or
