Description

What is the purpose of this test?

Both follicle-stimulating hormone (FSH) and luteinizing hormone (LH) are hormones associated with reproduction and the development of reproductive organs in women (eggs) and men (sperm). FSH & LH are made by a pea-sized gland found at the base of the brain, commonly known as the pituitary gland. Regulation of FSH & LH production is an intricate system comprised of the hypothalamus, pituitary gland, and the hormones produced by the reproductive organs (ovaries or testicles). The hypothalamus releases gonadotropin-releasing hormone (GnRH), which provokes the pituitary to release FSH & LH. Order this Follicle-Stimulating Hormone (FSH) and Luteinizing Hormone (LH) Blood Test Panel to measure FSH & LH levels and help screen for issues with fertility and reproductive organs, ovulation, or pituitary function.

 

What causes abnormal FSH & LH levels?

Several health conditions may cause a malfunction of the hypothalamus, pituitary, or reproductive organs, which can lead to abnormal production of FSH & LH, resulting in various conditions, such as infertility, irregular menstrual cycles, and early or delayed puberty. Abnormal FSH & LH levels may be caused by one or more of the following conditions:

 

  • Damage to the ovaries 
  • Radiation exposure or chemotherapy
  • Autoimmune disease
  • Polycystic ovary syndrome (PCOS)
  • Adrenal disease
  • Thyroid disease
  • Ovarian cancer
  • Pituitary disorder or problem with the hypothalamus
  • Viral infection (mumps)
  • Germ cell tumor
  • Gonadal agenesis
  • Klinefelter syndrome
  • Brain injury, trauma
  • Central nervous system tumor
  • Meningitis or encephalitis
  • Hormone deficiency
  • Turner syndrome
  • Eating disorder

 

When should I order an FSH & LH Blood Test Panel?

This FSH & LH Blood Test Panel is most useful when an individual has one of the following health conditions:

 

  • A woman having difficulty getting pregnant or is having irregular or no menstrual periods
  • A man with a low sperm count, low muscle mass, decreased sex drive, or when their partner cannot get pregnant
  • Individuals with symptoms of a pituitary disorder or hypothalamic disorder
  • A child suspected of having a delayed or earlier-than-expected puberty
