When sperm leave the epididymis, they are transported directly into the

A) seminal vesicles.
B) ductus deferens.
C) prostate gland.
D) urethra.
E) ejaculatory duct.

The ductus deferens, also known as the vas deferens, is the tube that carries sperm from the epididymis to the ejaculatory duct. The seminal vesicles, prostate gland, and bulbourethral gland contribute secretions to the semen as it passes through the reproductive tract, but the sperm are not transported directly into these glands or structures. The urethra serves as a common pathway for both semen and urine, but the sperm do not enter the urethra until they are expelled during ejaculation.
