Meiosis occurs specifically in which part of the human male reproductive system?

1. Vas deferens

2. Prostate gland

3. Testes

4. Scrotum

The correct answer is: Testes

Meiosis is the specialized process of cell division that reduces the chromosome number by half, resulting in the formation of gametes. In males, this process takes place in the testes, specifically within the seminiferous tubules. The testes are responsible for producing sperm cells through spermatogenesis, which involves meiosis to ensure that each sperm cell contains half the number of chromosomes, allowing for genetic diversity when fertilization occurs. The other options refer to components of the male reproductive system but do not directly involve the process of meiosis. The vas deferens is a duct that transports sperm from the testes to the urethra, the prostate gland produces seminal fluid that nourishes and supports sperm but does not participate in meiosis, and the scrotum is the external pouch that houses the testes and helps regulate their temperature. Thus, the correct focus on meiosis being specific to the testes is essential in understanding male reproductive biology.
