Which of the following glands secrete hormones that regulate male reproductive functions?

• A. Seminal vesicles
• B. Prostate gland
• C. Testes
• D. Bulbourethral glands

Answer: (C)

Verified step by step guidance

1. Identify the primary function of each gland listed in the options: Seminal vesicles, Prostate gland, Testes, and Bulbourethral glands.
2. Understand that the seminal vesicles and prostate gland primarily contribute to the production of seminal fluid, which supports sperm motility and viability, but do not secrete hormones.
3. Recognize that the bulbourethral glands produce a pre-ejaculatory fluid that helps lubricate the urethra, but they do not secrete hormones related to reproductive functions.
4. Focus on the testes, which are responsible for producing sperm and secreting male sex hormones, primarily testosterone, which regulates male reproductive functions.
5. Conclude that the testes are the glands that secrete hormones regulating male reproductive functions, as they produce testosterone, which is crucial for the development and maintenance of male secondary sexual characteristics and reproductive activity.
