Follicle stimulating hormone (FSH) - description and reference ranges

What is it?

Follicle-stimulating hormone (FHS) is one of the gonadotrophic hormones, together with Luteinising hormone (LH). These are normally tested together and are produced by the pituitary gland. FSH is responsible for puberty development and the development and function of ovaries and testes.

Reference ranges

If your indicative FSH concentration is lower than the reference range for our laboratory:

Low levels of follicle stimulating hormone can lead to incomplete development during puberty or poor subsequent ovarian function.

Please discuss this result with your GP.

If your indicative FSH concentration level is higher than the reference range for our laboratory:

Usually, elevated levels of follicle stimulating hormone are a sign of ovary problems or testis malfunction.

Please discuss this result with your GP.

    The PSA Blood Test and Prostate Cancer Screening

    In the UK, we screen for many different conditions. This starts before we are even born when foetuses are screened for conditions such as Down’s syndrome then, in the new born period, babies are screened for metabolic diseases and hearing problems, school children are screened for colour blindness, and in adulthood we are screened for breast cancer, cervical cancer, and bowel cancer. But we don’t screen for prostate cancer despite the existence of a simple blood test that can alert us to the possibility of the disease.
