What are the male gonads called?

The male gonads are referred to as testes, as they are the organs responsible for producing sperm and hormones, primarily testosterone. Testes play a critical role in the male reproductive system by facilitating the formation of sperm cells through a process known as spermatogenesis. They also contribute to the overall endocrine function by releasing hormones that influence secondary sexual characteristics and reproductive functions.

In contrast, the other options serve different functions or are related to different aspects of the reproductive system. Ovaries are the female gonads responsible for producing eggs and female hormones. The prostate is a gland that secretes fluid that nourishes and transports sperm but is not a gonad itself. The vas deferens is a muscular tube that transports sperm from the testes to the urethra, but it does not produce sperm or hormones.
