What is the role-played by luteinizing hormones in males and females respectively?

Open in App

Solution

Introduction to LH :

Luteinizing hormone (LH), secreted by the anterior lobe of the pituitary gland, is a gonadotropin. It stimulates the gonads in male (testes) and in females (ovaries) to produce their respective secretions.

Role of LH in males:

In males, LH stimulates the Leydig cells of the testes to secrete androgens, mainly testosterone. This is responsible for the development of secondary sexual characters.

Role of FSH in females:

Luteinizing hormone (LH) helps in maintaining corpus luteum in females which secretes progesterone. LH also induces ovulation of fully matured follicles (Graafian follicles).

Q. Testosterone is a steroid hormone produced by all vertebrate animals and, in humans and other mammals, it is secreted in large amounts by the testes of males and to a much lesser extent, the ovaries of females. In adult males, testosterone plays a key role in the development of reproductive organs and it promotes the secondary sexual characteristics of body and facial hair, increased muscle and bone mass, and a deep voice. Testosterone, like all hormones, works via long distance signaling and is regulated by other hormones as illustrated below:

Figure 1:

Testosterone regulation by cooperation between the hypothalamus, pituitary, and testicular endocrine glands. The major regulatory hormones involved are luteinizing hormone (LH), follicle-stimulating hormone (FSH) and gonadotropin-releasing hormone (GnRH).

When testosterone levels are low, gonadotropin-releasing hormone (GnRH) is released by the hypothalamus, which in turn stimulates the pituitary gland to release FSH and LH. FSH and LH then stimulate the testis to produce testosterone.
How is homeostasis achieved when testosterone levels begin to rise?
