Which of the following is part of the genito-urinary system for both men and women?

The ureters are a part of the genito-urinary system for both men and women because they are essential structures responsible for transporting urine from the kidneys to the bladder. Each individual has two ureters, regardless of gender, and they play a critical role in the urinary system's functionality.

In contrast, the testes, prostate, and scrotum are male-specific reproductive structures. The testes produce sperm and hormones, while the scrotum houses the testes, and the prostate contributes to seminal fluid. These structures are not present in women, which distinguishes them from the ureters that are common to both sexes. Therefore, understanding that the ureters function universally within the genito-urinary system helps clarify why this option is the only one applicable to both genders.
