What part of the male reproductive system is responsible for carrying sperm from the testes to the urethra? (A) The sperm ducts, vasa deferentia. (B) The prostate gland. (C) The scrotum. (D) The urinary bladder.

This question is asking us about the male reproductive system, which we can see here. The purpose of this system is to deliver semen, which contains sperm, to the female reproductive system using the penis. A sperm cell can then combine with an egg cell that’s been made by the female reproductive system to make a fertilized egg. This fertilized egg can then make a baby, which can develop in the female reproductive system.

To answer our question, let’s go through the parts of the male reproductive system and see how sperm is produced so it can be released by the penis. Sperm is produced in the testes, or testis as singular. These are sometimes called the testicles. Sperm are sensitive to high temperatures. So the testes are kept outside the body in a sac of skin called the scrotum. The sperm that are made in the testes are stored in a region called the epididymis. When the male is sexually aroused, the sperm can travel from the epididymis through a tube called the vas deferens. The sperm can then mix with fluids from different glands to form semen. One of these glands is called the seminal vesicle. Another gland that adds fluid to make semen is the prostate gland.

Now that semen is prepared, it can be ejaculated, or ejected, from a tube called the urethra. During sexual intercourse, the ejaculated semen can enter the female reproductive system, where a sperm cell in the semen can fertilize an egg cell. So the part of the male reproductive system that carries sperm to the urethra is the vas deferens. Because there’s one for each testicle, the plural form is the vasa deferentia. These are also known as the sperm ducts.

Therefore, answer choice (A) is correct: the sperm ducts, vasa deferentia.
