What are the target organs for Lutenizing Hormone (LH)?

Luteinizing hormone (LH) plays a crucial role in the reproductive system, and its target organs are the ovaries in females and the testes in males. In females, LH is essential for triggering ovulation and stimulating the production of progesterone from the corpus luteum, which is vital for maintaining the early stages of pregnancy. In males, LH stimulates the Leydig cells in the testes to produce testosterone, a hormone necessary for sperm production and the development of male secondary sexual characteristics.

The specificity of LH’s action on the ovaries and testes highlights its importance in regulating reproductive functions, differentiating it from the other options, which do not relate directly to the roles of LH in the endocrine system.
