This hormone is secreted by the anterior pituitary gland and works as a growth hormone for reproductive organs. In females, the FSH stimulates the growth of ovarian follicles and triggers the development of eggs and ovulation. Monitoring FSH levels is essential for assessing fertility and helps to diagnose the disorders for better treatment.

The FSH full form in Medical is Follicle-Stimulating Hormone. This hormone is produced by the anterior pituitary gland and plays a crucial role in regulating reproductive functions. It stimulates ovarian follicle growth in females which leads to egg maturation. In men, it promotes spermatogenesis and helps in the development of testes and sperm. Abnormal FSH levels can indicate issues with fertility, ovarian function, or hormonal balance.

What Does FSH Do?

FSH plays a vital role in both men's and women's bodies by regulating their reproductive health. This is done by controlling the production of sex hormones in the body. However, its levels fluctuate during the ovulation period. Know more about the function of FSH in the section below.

  • FSH stimulates the growth and development of ovarian follicles in the body. The process is essential for the maturation of eggs and their eventual release during ovulation
  • FSH helps to regulate estrogen production in the body. It does during the onset of the menstrual cycle and also maintains the overall reproductive health
  • The surge in FSH, along with another hormone called luteinizing hormone (LH). This eventually triggers the release of a mature egg from the ovary during ovulation
  • FSH stimulates the Sertoli cells in the testes, which are responsible for supporting the development and maturation of sperm cells
  • FSH also plays a minor role in supporting the production of testosterone by the testes

What is the FSH Test?

The FSH test is a blood test that measures the levels of the follicle-stimulating hormone in the blood. Generally, this hormone is produced by the pituitary gland and a small gland located at the base of the brain. This hormone is responsible for stimulating the growth and development of ovarian follicles in women and sperm production in men. The FSH levels are done to check the following:

  • Assessing Ovarian Function to rule out the possibility of early menopause or infertility
  • Evaluating Male Reproductive Health helps in assessing the functioning of the testes and sperm production
  • Monitoring the growth of fertility treatments like IVF
  • Diagnosing Hormonal Imbalances and disorders of the pituitary gland

FSH Normal Levels

The FSH levels fluctuate during the menstrual cycle of women. It is usually seen that the levels are high during the early follicular phase and lowest during the luteal phase after the ovulation process is over. Refer to the table below to know about the normal range of FSH levels.

Situation Normal Levels
Before puberty 0 to 5.0 mIU/mL
During puberty 0.3 to 10.0 mIU/mL
Adult 1.5 to 12.4 mIU/mL

Signs of Low FSH

The following are the major signs and symptoms related to low FSH levels in the body.

  • Irregular Menstrual Cycles
  • Infertility in women
  • Delayed Puberty in both girls and boys
  • Low Libido in women and men
  • Erectile Dysfunction in Men
  • Delayed or Slower Growth Issues
  • Pituitary Dysfunction
  • Hypothalamic Dysfunction

Signs of High FSH

High levels of FSH levels in the blood can cause a range of health issues related to the reproductive organs. Check out the section below to know about the major signs related to FSH levels in the body

  • High FSH levels can lead to irregular or absent menstrual periods in women
  • Elevated FSH levels indicate diminished ovarian reserve and do not allow the women to conceive
  • High FSH levels can be a sign of early menopause or premature ovarian insufficiency. This can also cause menopausal symptoms at a younger age
  • Hot flashes and night sweats occur due to disrupted hormonal balance, including elevated FSH levels
  • Hormonal fluctuations can lead to mood swings, irritability, and emotional changes
  • High FSH levels in the body can lead to a lower response to Invitro fertilization (IVF)
