Follicle-Stimulating Hormone (FSH) Test

The FSH Test at Pamel Laboratories measures the level of Follicle-Stimulating Hormone (FSH) in the blood. FSH is produced by the pituitary gland and plays a critical role in sexual development, puberty, and the function of reproductive organs in both men and women. In women, FSH helps regulate the menstrual cycle and stimulate ovarian follicle development, while in men, it is essential for sperm production.

This test is commonly used to evaluate infertility, monitor menopausal status, and assess pituitary function.

What the Test Measures:

• The concentration of FSH in your blood

• Indicates how well the reproductive system and pituitary gland are functioning

Purpose of the Test:

• In women:

  • Evaluate irregular menstrual cycles

  • Diagnose menopause or early menopause

  • Investigate infertility or ovarian dysfunction

• In men:

  • Assess low sperm count or testicular dysfunction

  • Diagnose pituitary or hypothalamic disorders

• In children:

  • Diagnose delayed or early puberty

Sample Type: Blood sample (serum)
Fasting Required: No
Best Time for Test (Women): Often performed on day 3 of the menstrual cycle
Turnaround Time: 1–2 working days

Interpretation Guide:

• High FSH in women: May suggest ovarian failure, menopause, or polycystic ovary syndrome (PCOS)

• Low FSH in women: May point to pituitary or hypothalamic dysfunction

• High FSH in men: May indicate testicular damage or failure

• Low FSH in men: Could suggest pituitary gland issues

Often interpreted alongside LH, estradiol, or testosterone for a full reproductive hormone profile
