What is the function of the duct us deferential?

The ductus deferens, also known as the vas deferens, is a muscular tube that transports sperm from the epididymis to the ejaculatory duct during ejaculation. It plays a crucial role in the male reproductive system by facilitating the movement of sperm and mixing it with seminal fluid to form semen. The muscular contractions of the ductus deferens help propel the sperm forward, ensuring they reach the urethra for expulsion from the body.
