Prostate gland
Verified step by step guidance
1
Step 1: Understand the function of each structure listed in the male reproductive system. The vas deferens is a tube that transports sperm from the testes to the urethra. The seminal vesicles produce a fluid that nourishes and helps transport sperm. The prostate gland secretes a fluid that is part of semen. The testes are responsible for producing sperm cells and testosterone.
Step 2: Recall the anatomy and physiology of the testes. The testes contain seminiferous tubules, where spermatogenesis (the production of sperm cells) occurs. This process is regulated by hormones such as testosterone and follicle-stimulating hormone (FSH).
Step 3: Eliminate incorrect options based on their functions. The vas deferens, seminal vesicles, and prostate gland do not produce sperm cells; they are involved in the transport and support of sperm or semen production.
Step 4: Confirm that the testes are the correct answer by reviewing their primary role in the male reproductive system. The testes are the site of sperm cell production and hormone secretion, making them the correct choice.
Step 5: Reinforce the concept by noting that the testes are located in the scrotum, which provides a cooler environment necessary for optimal sperm production.
