Understanding Follicle Stimulating Hormone (FSH): What It Is and How It Works?
Your general health is greatly influenced by hormones, which control everything from growth and metabolism to how you react to stress. In relation to a woman's ovarian reserve, follicle-stimulating hormone (FSH) is crucial for sexual development and function (egg quantity). Continue reading to find out more about follicle-stimulating hormone (FSH) and how it relates to menopause if you're interested.
What Is Follicle-stimulating hormone (FSH)?
The pituitary gland in the brain releases a hormone called follicle-stimulating hormone (FSH), which instructs the ovary when to make oestrogen, allow the eggs to mature, and prepare them for ovulation.
What is Follicle Stimulating Hormone (FSH)?
FSH is a hormone produced by the pituitary gland in the brain. It plays an important role in both males and females. In females, FSH is responsible for the growth and development of ovarian follicles, which contain the eggs that are released during ovulation. In males, FSH stimulates the production of sperm in the testicles.
How Does FSH Work?
Follicle Stimulating Hormone function differently in both men and women:
In females, FSH is produced by the pituitary gland and released into the bloodstream. It then travels to the ovaries, where it stimulates the growth of ovarian follicles. These follicles contain immature eggs that are not yet ready for fertilization. As the follicles grow, they produce estrogen, which signals the pituitary gland to decrease FSH production. Eventually, one dominant follicle will continue to grow while the others will shrink and be reabsorbed by the body. This dominant follicle will release a mature egg during ovulation.
In males, FSH works in a similar way. It is produced by the pituitary gland and released into the bloodstream. It then travels to the testicles, where it stimulates the production of sperm. FSH works in conjunction with luteinizing hormone (LH) to regulate the production of testosterone, which is essential for sperm production.
Why FSH Test Is Needed?
The follicle stimulating hormone test is a blood test that quantifies the amount of FSH present in the body. The test is commonly used to assess fertility in both men and women.
Women's low FSH levels could be brought on by:
Being extremely underweight or having recently lost a lot of weight
Not laying eggs (not ovulating)
Hormone production in the brain's pituitary gland or hypothalamus is not producing all of its hormones at normal levels.
Pregnancy
It may be a sign that a woman has entered menopause if her FSH blood level is regularly 30 mIU/mL or more and she hasn't had a period in a year.
