Structure of Luteinizing Hormone

LH is a glycoprotein hormone composed of two subunits, alpha and beta. The alpha subunit is shared with other pituitary hormones, while the beta subunit is unique to LH. The beta subunit is responsible for the specific biological activity of LH.

Functions of Luteinizing Hormone

LH plays a crucial role in the following functions:

Stimulating ovulation in females
Regulating the menstrual cycle in females
Stimulating the production of testosterone in males
Regulating the function of the gonads in both males and females

Regulation of Luteinizing Hormone

LH production is regulated by a negative feedback loop involving the sex hormones it stimulates. For example, in females, rising estrogen levels during the menstrual cycle inhibit LH production, until a surge in estrogen triggers a spike in LH, leading to ovulation.

Clinical Significance

Abnormal levels of LH can indicate various health conditions, such as polycystic ovary syndrome (PCOS) in females and hypogonadism in males.

Study Guide for Luteinizing Hormone

To effectively study luteinizing hormone, you should focus on the following key areas:

Understand the structure of LH, including the composition and function of its subunits.
Learn the regulatory mechanisms that control LH production, including the role of GnRH and feedback loops involving sex hormones.
Explore the specific functions of LH in both males and females, including its role in the menstrual cycle and reproductive processes.
Examine the clinical implications of abnormal LH levels and the conditions associated with these abnormalities.
