The follicle-stimulating hormone or FSH blood test measures the level of FSH in blood. FSH is a hormone released by the pituitary gland in men and women and plays an essential role in reproduction.
The doctor recommends an FSH Test to check the cause of infertility, irregular mensuration, amenorrhea (Missing periods in women), To diagnose any dysfunction of ovaries or testicles, hypothalamic disorder, delayed or early puberty in children, low sperm count, decreased libido
The main component checked by this test is a Follicle-stimulating hormone (FSH blood test) which is secreted from the anterior pituitary gland in a pulsatile manner. This hormone is necessary for normal pubertal development and is responsible for fertility in both men and women.
Blood sample is taken from the vein. In a female patient, the sample is collected at specific times during her menstrual cycle. No need to fast. Sometimes urine sample is also collected to check the FSH.
Basal level in premenopausal women depends on age, smoking history, length, and menstrual cycle regularity.
|Male 13-70 Years||1.4- 18.1 IU/L|
|Female Normally menstruating|
|Follicular Phase||2.5-10.2 IU/L|
|Midcycle Peak||3.4- 33.4 IU/L|
|Luteal Phase||1.5-9.1 IU/L|
|Postmenopausal||23.0 -116.3. IU/L|
These values are for theoretical reference and may vary from laboratory to laboratory and person to person.
Tanner Stage (FSH MIU/ML)
|Males (MIU/ML)||1- 0.4-3.0
|Female (MIU/ML)||1- 0.8-6.5
