Which glandular structure is primarily responsible for male hormone production?

The testes are the primary glandular structures responsible for male hormone production, specifically testosterone. Testosterone is essential for the development of male secondary sexual characteristics, such as increased muscle mass, body and facial hair growth, and deepening of the voice. The testes also play a critical role in sperm production, making them vital for male reproductive health.

In contrast, the ovaries are responsible for female hormone production and are involved in the female reproductive system. The thyroid gland primarily regulates metabolism and does not produce male hormones. The adrenal glands, located on top of each kidney, produce a variety of hormones, including some androgens, but the primary source of male hormones is the testes. This specificity of function is crucial for understanding male endocrine health.
