Definition
Noun: A gonadotropic hormone secreted by the anterior pituitary gland. In females, it stimulates ovulation and the development of the corpus luteum. In males, it stimulates the Leydig cells of the testes to produce androgens, primarily testosterone.
Usage
This is a technical, scientific term used primarily in the fields of endocrinology, biology, and medicine. It refers to a specific chemical messenger in the body's endocrine system.
Examples
- The doctor explained that a surge in ICSH triggers the release of an egg from the ovary.
- In male physiology, ICSH is essential for the production of testosterone.
- The laboratory test measured the patient's levels of ICSH and FSH.
Advanced Usage
- The term ICSH is functionally synonymous with Luteinizing Hormone (LH), which is the more commonly used term in modern clinical and scientific contexts. "ICSH" (Interstitial Cell-Stimulating Hormone) is an older name that emphasizes its role in stimulating the interstitial cells (Leydig cells) in the testes.
Variants and Related Words
- LH (Luteinizing Hormone): The standard contemporary term for this hormone.
- Gonadotropin: The class of hormones to which ICSH/LH belongs, which act on the gonads (ovaries and testes).
- FSH (Follicle-Stimulating Hormone): Another pituitary gonadotropin that works in concert with ICSH/LH.
Synonyms
- Luteinizing Hormone (LH)
- Gonadotropic hormone (specific type)
Notes on Meaning
While "ICSH" and "LH" refer to the identical molecule, the choice of term can be context-dependent. "ICSH" is sometimes used specifically when discussing its function in the male reproductive system, whereas "LH" is used as the universal term for both sexes. In modern usage, "LH" has largely superseded "ICSH".
Noun
- a gonadotropic hormone that is secreted by the anterior pituitary; stimulates ovulation in female mammals and stimulates androgen release in male mammals
