Question

Which of the following is a function of testes?

• A. Secreting testosterone hormone
• B. Production of sperms
• C. Secreting progesterone hormone
• D. Both (A) and (B)

Hint:

Remember the dual function of gonads (testes in males, ovaries in females): producing gametes (sperm/eggs) and producing sex hormones.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
The testes (singular: testis) are the male gonads in animals. The question asks for their primary biological functions.

Step 2: Detailed Explanation:
The testes have two main functions:

Spermatogenesis: The production of male gametes, which are the sperms.
Endocrine function: The synthesis and secretion of male sex hormones, primarily testosterone, which is responsible for the development of male secondary sexual characteristics.
Option (C), secreting progesterone, is incorrect as progesterone is a primary female sex hormone. Since both (A) and (B) are correct functions of the testes, option (D) is the best answer.

Step 3: Final Answer:
The functions of the testes are to secrete testosterone and to produce sperms.
