Question

Write an essay on endocrine function of gonads.

Answer 1

Gonads:

Both tests and ovaries, in addition to their role as reproductive gamete producing organs, function as endocrine structures also.

Testis:

The testis contains epithelioid cells called the interstitial or Leydig cells. The Leydig cells secrete the androgenic hormone testosterone.

Action of testosterone:

1. Testosterone causes the embryonic development of male reproductive organs.

2. It promotes the development of the secondary sexual characters of males.

Ovary:

The ovaries are responsible for the production of oestrogen, progesterone and testosterone.

Action of hormones:

1. Testosterone is involved in the development of body mass and bone strength in the case of females.

2. Oesterogen is responsible for the development of secondary sexual characters in females.

3. Progesterone is responsible for maintaining pregnancy and lactation.
