FSH Test (Follicle-Stimulating Hormone) & Luteinizing Hormone (LH)

The FSH and LH Test measures the levels of Follicle Stimulating Hormone and Luteinizing Hormone in your blood to evaluate reproductive health and hormonal balance. These two hormones are produced by the pituitary gland and work together to regulate the reproductive system in both women and men.

In women, FSH stimulates the growth and maturation of ovarian follicles, while LH triggers ovulation and supports progesterone production. In men, FSH supports sperm production and LH stimulates the testes to produce testosterone. Because these hormones are closely connected to fertility and sexual development, their balance is essential for normal reproductive function.

Abnormal levels of FSH and LH can signal a variety of conditions. In women, imbalances may be associated with menopause, polycystic ovary syndrome, irregular menstrual cycles, or ovarian dysfunction. In men, abnormal levels may indicate testicular dysfunction, low testosterone production, or certain genetic conditions. These hormones are also important in evaluating early or delayed puberty.

By measuring both FSH and LH together, this test provides a clearer picture of how the brain and reproductive organs are communicating. It helps determine whether symptoms are related to the ovaries or testes themselves, or to the hypothalamus and pituitary gland that control hormone production.

What Is Included In This Test?

This test includes:

• Measurement of Follicle Stimulating Hormone, FSH
• Measurement of Luteinizing Hormone, LH
• Clear numerical results for clinical interpretation

This panel evaluates FSH and LH only and does not include estrogen, progesterone, or testosterone.

Why Does This Test Matter?

FSH and LH are central regulators of fertility, menstrual cycles, testosterone production, and puberty. When these hormones fall outside normal ranges, it can disrupt ovulation, sperm production, and overall hormonal balance.

In women, high FSH and LH levels may indicate menopause or diminished ovarian function. Irregular LH patterns may be associated with polycystic ovary syndrome. In men, elevated levels may signal primary testicular dysfunction, while low levels may suggest pituitary or hypothalamic disorders.

This test is also essential when evaluating early or delayed puberty. Abnormal levels help identify whether developmental concerns are caused by primary reproductive organ dysfunction or by central hormonal regulation issues.

Understanding your FSH and LH levels supports accurate diagnosis, targeted treatment planning, and informed fertility or hormone management decisions.

Who Should Consider This Test?

You may consider this test if you:

• Are experiencing infertility
• Have irregular or absent menstrual cycles
• Suspect menopause or perimenopause
• Have abnormal vaginal bleeding
• Have been diagnosed with or suspect polycystic ovary syndrome
• Have early or delayed puberty
• Are a male with low testosterone symptoms
