Follicle Stimulating Hormone (FSH) Test
The FSH test determines the concentration of follicle-stimulating hormone (FSH) in the blood. The pituitary gland, a tiny gland lying under the brain, produces FSH. FSH is essential for sexual growth and function.
- In women, FSH plays a crucial role in regulating the menstrual cycle, promoting the development of eggs in the ovaries, and reaching its peak just before ovulation, which triggers the release of an egg.
- In men, FSH is responsible for regulating sperm production, and its levels generally remain stable.
- In children, FSH levels are typically low until puberty, where it signals the ovaries to produce estrogen in females and stimulates the testes to produce testosterone in males.
- Normal FSH levels and Abnormal FSH levels can lead to various issues. In women, it can cause infertility and menstrual problems.
- Men may experience a decrease in sex drive due to low FSH levels.
- In children, abnormal FSH levels can result in early or delayed puberty.
Other names: Follitropin, FSH, and follicle-stimulating hormone: serum; are some of the other names for this hormone.

Get A Second OpinionUses of FSH testing
To manage sexual functioning, FSH collaborates with another hormone called luteinizing hormone (LH). As a result, a luteinizing hormone test is frequently performed in conjunction with an FSH test.
FSH testing is used differently for women, men, and children:
For women, it helps to:
For men, the test is used to:
- Determine infertility causes.
- Investigate low sperm count.
- Assess testicular function.
For children, FSH testing helps detect early or delayed puberty:
- Early puberty is before age 9 in girls and age 10 in boys.
- Delayed puberty is when it hasn't started by age 13 in girls and age 14 in boys.
This test provides important insights into hormonal health and development.
What is the need of an FSH-level test?
In Women
Women may require this test if they have the following:
- After a year of trying, you've been unable to conceive.
- Your menstrual cycle is disturbed.
- Your menstrual cycle has come to an end. The test can determine if you have gone through menopause or are in perimenopause.
In Men
Men may require this test if they have the following:
- After a year of trying, you and your partner cannot conceive.
- Your sexual desire has dropped.
When to get the FSH test done?
If you have signs of a pituitary issue, both men and women should be tested. Some of them include the symptoms described above, as well as:
If your child does not appear to be entering the puberty stage at the appropriate age, an FSH test may be required (either too early or too late).
What takes place during an FSH-level test?
During an FSH test, a medical practitioner will utilize a minuscule needle to extract blood from a vein in your arm.
- Following the insertion of the needle, a small quantity of blood will be gathered in a test tube or vial.
- It is possible to experience a mild sensation when the needle is inserted or withdrawn.
- On average, the procedure usually lasts approximately five minutes.
Symptoms of FSH high levels
In females, elevated FSH levels are often indicative of menopause, leading to symptoms such as:
- Hot flashes
- Weight gain
- Vaginal dryness
- Irregular menstruation
- Sleep disturbances
- Emotional changes
- Bone loss
Additionally, a rare condition known as ovarian hyperstimulation syndrome (OHSS) may be associated with elevated FSH levels.
Is there any risk in the FSH test?
Having a blood test poses relatively no risk or danger. You may experience discomfort or bruising where the needle was inserted, but most symptoms will go away soon.
- Excessive Bleeding
- Fainting or Lightheadedness
- Multiple Punctures
- Hematoma (Blood Under Skin)
- Infection Risk
What do the findings imply?
The significance of your results will differ depending on whether you are a woman, a man, or a kid.
Women
High FSH levels in women may indicate the following:
- POI is an abbreviation for primary ovarian insufficiency, often known as premature ovarian failure. POI is defined as ovarian function loss before the age of 40.
- PCOS (polycystic ovarian syndrome) is a prevalent hormonal condition that affects childbearing women. It is a leading cause of female infertility.
- Menopause or perimenopause
- Receiving hormone therapy
- Ovarian cancer
- Turner syndrome is a hereditary condition that impairs female sexual development. It frequently results in infertility.
Low FSH levels in women may indicate:
- Your ovaries are producing insufficient eggs.
- Your pituitary gland is malfunctioning.
- You have an issue with your hypothalamus, which is a region of the brain that regulates the pituitary gland and other vital bodily processes.
- You are underweight.
Men
High FSH levels in men may indicate:
- Chemotherapy, radiation, infection, or alcohol misuse have all destroyed your testicles.
- Damage to testicles due to chemotherapy, radiation, alcohol abuse, and hormonal treatment.
- You have Klinefelter syndrome, a hereditary condition that impairs male sexual development. It frequently results in infertility.
Low FSH levels may indicate a pituitary or hypothalamic issue in men.
High FSH levels in youngsters and high luteinizing hormone levels may indicate that puberty is about to begin or has already begun. If this occurs before the age of 8 in a girl or before the age of 9 in a male (precocious puberty), it might be an indication of:
- A central nervous system disorder
- A traumatic brain injury
Low levels of FSH and luteinizing hormone in children may indicate delayed puberty. Delayed puberty can result from the following:
- A problem with the ovaries or testicles.
- Turner syndrome in women.
- Boys with Klinefelter syndrome.
- An infection.
- A hormonal imbalance.
- Eating disorders.
Speak with your healthcare practitioner if you have any questions regarding your or your child's results.
