LUTEINISING HORMONE Meaning and
Definition
-
Luteinising hormone (LH) is a hormone produced and secreted by the anterior pituitary gland in the brain. It plays a crucial role in regulating reproductive function in both males and females.
In males, LH stimulates the production and secretion of testosterone by the Leydig cells present in the testes. This hormone is responsible for the development and maturation of the testes, as well as the production of sperm.
In females, LH plays a key role in the menstrual cycle and ovulation process. It stimulates the release of an egg from the ovary during the middle of the menstrual cycle, a phenomenon known as ovulation. Additionally, LH facilitates the development and maintenance of the corpus luteum, a temporary endocrine structure that secretes progesterone to prepare the uterus for potential pregnancy.
The secretion of LH is regulated by a complex interplay of hormones from the hypothalamus and feedback mechanisms involving sex hormones such as estrogen and testosterone. LH levels fluctuate throughout the menstrual cycle, with a surge occurring just before ovulation in females.
Abnormal levels of luteinising hormone can have various implications and may be indicative of underlying conditions. High levels of LH in females may indicate polycystic ovary syndrome (PCOS) or menopause, whereas low levels can be associated with conditions such as hypogonadism or pituitary disorders.
In summary, luteinising hormone is a vital hormone that regulates reproductive functions in both males and females, such as the production of testosterone, ovulation, and menstrual cycle regulation.

Etymology of LUTEINISING HORMONE
The word "luteinising hormone" is derived from the term "luteinizing" and the word "hormone".
The term "luteinizing" refers to a specific hormone-releasing process that occurs in the female reproductive system. It comes from the Latin word "luteus", meaning "yellow", referring to the color of the corpus luteum, a temporary hormone-secreting structure in the ovaries.
The word "hormone" is derived from the Greek word "hormon", meaning "to set in motion" or "to excite". It was first used in the late 19th century to refer to chemical messengers produced by various glands in the body that regulate different physiological processes.
