FSH, also known as Follicle-stimulating Hormone, is a hormone produced by the pituitary gland. FSH regulates the functions of both the ovaries and the testes and plays a pretty important part in pubertal development[1].

Let’s delve into the topic of FSH, learn about the symptoms of low FSH and find out what causes low levels of FSH.



What Are The Symptoms Of Low FSH?


FSH is one of the gonadotrophic hormones - the other being Luteinizing Hormone (LH). FSH is essential in pubertal development and in the function of women’s ovaries and men’s testes[2].

FSH levels can vary during the menstrual cycle and they usually peak just before ovulation. That said, some women may experience consistent low FSH levels and symptoms associated with this can include [3]:

  • Hot flashes
  • Irregular or no periods
  • Loss of pubic hair
  • Inability to produce milk for breast-feeding

What does it mean when your FSH is low?

Low FSH levels can have a significant effect on a woman’s reproductive system - it can result in incomplete development at puberty and poor ovarian function; each of which may lead to infertility[4].


What causes low levels of FSH?


If you’re experiencing low levels of FSH, it could be a result of a rare disorder called Hypopituitarism - this occurs when you have a short supply of one or more pituitary hormones; this includes FSH [5].

Some causes of hypopituitarism may include [6]:

  • Head injuries
  • Radiation treatment to the head or neck
  • Lack of blood flow to the brain
  • Infections to the brain
  • Genetic mutation

How do I check my FSH levels?


You can test your FSH levels with a simple blood test - this can be done with your local doctor or from the comfort of your own home.
