What two structures are inside the scrotum?

The correct identification of the two structures located inside the scrotum is indeed the testes and the epididymis. The scrotum is a pouch of skin that contains the testes, which are the male reproductive organs responsible for producing sperm and hormones, primarily testosterone. The epididymis is a coiled tube that sits atop each testis and functions in the maturation and storage of sperm.

The presence of these two structures in the scrotum is crucial for the male reproductive system, as their location outside the body helps regulate the temperature necessary for sperm production and storage. Sperm develop optimally at a temperature slightly lower than the body's internal temperature, making the scrotum an essential component of male fertility.

Other options provided do not correctly identify structures within the scrotum. The prostate gland and seminal vesicles, for instance, are part of the male reproductive system but are located in the pelvic cavity, not within the scrotum.
