How are FSH levels related to age and fertility?

PUNJAB NEWS EXPRESS | September 20, 2022 09:23 PM

We must manage a certain set of hormones at every stage of our life to function adequately. In this article, we are going to learn a lot about the FSH test, [also known as follicle stimulating hormone]. 

Four main hormones—estrogen, progesterone, LH, and FSH—are responsible for regulating the menstrual cycle. FSH, or follicle stimulating hormone, is named in a way that is quite illustrative: it stimulates the development and maturation of follicles in the ovaries in order to prepare them for ovulation. 

Each of these follicles then develops until it is prepared to release an egg. All of this happens during the follicular phase, the first part of your cycle. Ovulation and a woman's cycle can be managed with the use of the full therapy program. Follicle-stimulating hormone (FSH), hormone, is essential for reproduction. FSH regulates the menstrual cycle and encourages ovarian egg formation. FSH helps males produce sperm. 

Read the complete article to know how FSH is related to fertility and age, what is FSH test, and what FSH blood test range under normal conditions. 

How is FSH related to fertility?

Estradiol, a kind of estrogen that helps with egg development and release from the follicle, is created by the body in larger amounts in women as a result of FSH. At the end of your period, when estrogen levels are low, the pituitary gland is stimulated to generate more FSH, which promotes the development of eggs in the ovary. This procedure aids in the egg's liberation from the follicle. 

At ovulation, just one follicle typically develops an egg, however, there may be others. Your body recycles the abandoned follicles. FSH increases testosterone levels and triggers the synthesis of a protein required for the growth and upkeep of sound sperm cells in male testicles. 

FSH level in women:

In women FSH level do the following functions:

  • Consequently, follicular growth begins.
  • It has power over the menstrual period.
  • Additionally, oestradiol production is rising.
  • It stimulates the ovary, which produces an egg.
  • It regulates sexual development, maturation, and expansion as well as the management of reproductive activities.
  • This hormone encourages the growth of ovarian follicles in the ovary before an egg is released from a single follicle at ovulation. 

FSH level in men:

In men FSH plays the following function:

  • Sertoli or "nurse" cells as a result release androgen-binding proteins (ABPs).
  • This hormone, also referred to as spermatogenesis, promotes sperm production in the testicular "nurse" cell. 

How does age affect the FSH level?

Age, status throughout puberty, and gender all affect FSH levels. Like with most other hormones, comparing your test result to the reference range usually yields the typical range for FSH. The following FSH levels are frequently recognized as normal by age when values are based on day 3 of a typical cycle:

  • Age 33 or younger: 7.0 mlU/mL or less (milli-international units per milliliter)
  • 9 mIU/mL for people aged 33–37
  • 4 mIU/mL in people aged 38 to 40.
  • Less than 8.5 mIU/mL for people over the age of 41 

Note: It's essential to keep in mind that FSH reference values differ depending on the testing site. To ascertain whether your FSH levels are typical for your age, it is crucial to compare your level to the reference range set by the lab that conducted the FSH test for you. 

What is the FSH test?

The main goal of an FSH test is to determine the level of follicle-stimulating hormone (FSH) in a sample of blood. The FSH test figures out how much FSH is in your blood. Your doctor will run an FSH test in order to identify the root cause of reproductive system issues. In order to know your FSH level you have to go through an FSH blood test. 

Purpose of FSH test:

  • The major purpose of FSH test, which is performed on both men and women, is to identify the causes of infertility.
  • Failure of the ovaries is another application for the FSH test.
  • The pituitary adenomas.
  • the cause of a low sperm count.
  • the causes of early menopause.
  • kid puberty that occurs too soon or too late. 

The FSH blood test reports will let you know the real deal. Read below the normal range of FSH level. 

Male FSH levels should be between:

  • Between 0 and 5.0 mIU/mL before puberty.
  • 3 to 10.0 mIU/mL throughout puberty
  • Adult: 1.5–12.4 mIU/mL. 

Female FSH levels should be between:

  • Between 0 and 4.0 mIU/mL before puberty.
  • 3 to 10.0 mIU/mL throughout puberty
  • 7 to 21.5 mIU/mL for females who are still in menstruation.
  • 8 to 134.8 mIU/mL following menopause 


The reproductive system is crucially dependent on the hormone called follicle-stimulating hormone (FSH). Ovarian follicle development is a result of it. Women's menstrual periods are supported by follicles, which assist the ovaries to create the hormones progesterone and estrogen. FSH plays a role in both sperm generation and the growth of the gonads in men. If you face any issues then you should immediately consult your doctor and get your FSH blood test done.
