Which structure is part of the male reproductive system?

• A. Testes, epididymides, ductus deferentia
• B. Ovary
• C. Uterus
• D. Vagina

Answer: (A)

Recognizing which structures belong to the male reproductive system. The group that includes the testes, epididymides, and ductus deferentia are male reproductive components: the testes produce sperm and testosterone; the epididymis stores and matures sperm; the ductus deferens carries sperm from the epididymis to the urethra during ejaculation. The other options are female reproductive structures: the ovary produces eggs; the uterus is where a fertilized egg implants and develops; the vagina is the canal that leads to the uterus for intercourse and birth. So the structures listed together in the first group are the ones that are part of the male reproductive system.
