What part of the male genital system surrounds the urethra?

The prostate is a gland located below the bladder in the male reproductive system and surrounds the urethra as it passes through the pelvic region. Its primary function includes secreting fluid that nourishes and protects sperm, contributing to seminal fluid during ejaculation. The prostate plays a critical role in male fertility and overall reproductive health.

In contrast, the seminal vesicles are glands that produce fluid that nourishes sperm but do not surround the urethra. The epididymis is a coiled tube that stores and matures sperm, and it is not directly involved in surrounding the urethra. The testes are the male reproductive organs that produce sperm and testosterone, but they are not positioned around the urethra. Thus, the anatomical relationship of the prostate to the urethra is what distinguishes it as the correct answer in this scenario.
