Question

Which hormone is secreted by the gonads? Describe their role played by hormone in our body.

Answer 1

Gonads refer to the primary reproductive organs, which are the testes in males and ovaries in females. They secrete the following hormones:

Male Gonads (Testes): They secrete the androgen hormone called testosterone.

• Role: Testosterone stimulates the development of male secondary sexual characteristics such as facial hair, deepening of the voice, and muscular growth. It also stimulates the production of sperms (spermatogenesis).

Female Gonads (Ovaries): They secrete two main steroid hormones called estrogen and progesterone.

• Role of Estrogen: It regulates the development of female secondary sexual characteristics like breast development, high-pitched voice, and controls the changes during the menstrual cycle.
• Role of Progesterone: It prepares the inner uterine lining (endometrium) for the implantation of a fertilized egg and maintains pregnancy.
