Which hormone is not produced by the testes?

Correct option is A

Sol. Testosterone is not produced by the testes, but rather by the adrenal glands in both males and females. While the testes are the primary source of testosterone in males, some amount is produced by the adrenal glands as well. The question asks for a hormone that is not exclusively produced by the testes, making option (a) the correct answer.
Explanation of each option:
· (a) Testosterone – Correct answer. While the testes produce the majority of testosterone, it is also produced by the adrenal glands, meaning that it is not exclusively produced by the testes.
· (b) TSH (Thyroid-Stimulating Hormone) – Secreted by the pituitary gland, not the testes. It controls the thyroid gland’s hormone production and plays no role in male reproductive functions.
· (c) Cortisol – Produced by the adrenal glands, not the testes. It is a stress hormone that helps regulate metabolism, immune response, and inflammation.
· (d) Insulin – Produced by the pancreas, not the testes. It regulates blood sugar levels by promoting glucose uptake into cells, preventing diabetes.
