FSH / LH


divider

Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) are two important hormones that play crucial roles in the regulation of the reproductive system in both males and females. These hormones are produced and secreted by the anterior pituitary gland, and their release is controlled by the gonadotropin-releasing hormone (GnRH) from the hypothalamus.

 

FSH (Follicle-Stimulating Hormone):

  • In Females: FSH is primarily responsible for stimulating the growth and maturation of ovarian follicles (the structures that contain the eggs) in the ovaries. It also plays a role in the production of estrogen by the follicles.
  • In Males: FSH is involved in the stimulation of sperm production (spermatogenesis) in the testes by acting on the Sertoli cells, which are essential for nurturing and supporting the developing sperm cells.

LH (Luteinizing Hormone):

  • In Females: LH is responsible for triggering ovulation, which is the release of a mature egg from an ovarian follicle. It also promotes the formation of the corpus luteum, which produces progesterone to prepare the uterus for a potential pregnancy.
  • In Males: LH stimulates the Leydig cells in the testes to produce testosterone, which is crucial for the development of male secondary sexual characteristics and the maintenance of sperm production.

Regulation:

  • The levels of FSH and LH in the body are regulated through a feedback loop involving the hypothalamus, pituitary gland, and the gonads (ovaries in females, testes in males).
  • In females, the menstrual cycle is characterized by fluctuations in FSH and LH levels, which coordinate the different phases of the cycle (follicular phase, ovulation, luteal phase).
  • In males, FSH and LH levels are relatively stable, maintaining continuous sperm production and testosterone levels.

Hormones: Your FAQs

Welcome to Velvet Blood Clinic, your premier destination for all inquiries related to blood tests.

 

What is the role of FSH and LH in the reproductive system?

 

 

 

 

 

 

 

FSH and LH are crucial hormones for regulating the reproductive system. In females, FSH stimulates the growth of ovarian follicles, while LH triggers ovulation and supports the development of the corpus luteum. In males, FSH supports sperm production in the testes, and LH stimulates testosterone production, which is essential for sperm development.

How are FSH and LH levels tested?

 

FSH and LH levels are typically tested through a blood test. This test measures the concentration of these hormones in the bloodstream and is often used to assess reproductive health, diagnose hormonal imbalances, or evaluate fertility issues.

What do abnormal levels of FSH and LH indicate?

 

Abnormal levels of FSH and LH can indicate various health issues. Elevated levels might suggest conditions such as primary ovarian insufficiency in females or primary testicular failure in males. Low levels might be associated with hypothalamic or pituitary disorders. It's important to consult a healthcare provider for an accurate diagnosis and appropriate treatment based on the test results.

How do FSH and LH levels change during the menstrual cycle?

 

FSH and LH levels fluctuate throughout the menstrual cycle. FSH levels rise in the follicular phase to stimulate follicle growth, peaking just before ovulation. LH levels surge sharply right before ovulation, which triggers the release of the egg from the ovary. After ovulation, both FSH and LH levels decrease during the luteal phase.
