"ejaculatory duct"の定義と意味

What is "ejaculatory duct"?

The ejaculatory duct is a crucial part of the male reproductive system, formed by the union of the vas deferens and the seminal vesicle. It acts as a passage for the transport of seminal fluid into the urethra during ejaculation. The ejaculatory duct plays a significant role in the propulsion of sperm cells and seminal fluid, facilitating their release from the body during sexual intercourse. By connecting the structures involved in sperm production and storage with the urethra, the ejaculatory duct ensures the proper delivery of sperm for fertilization.
