where does the ejaculatory duct enter the urethra
Ejaculatory duct The ejaculatory ducts (ductus ejaculatorii) are paired structures in male anatomy.[1] Each ejaculatory duct is formed by the union of the vas deferens with the duct of the seminal vesicle.[2] They pass through the prostate, and open into the urethra at the seminal colliculus. During ejaculation, semen passes through the prostate gland, enters the urethra and exits the body via the urinary meatus.[3]
Vas deferens During ejaculation, the smooth muscle in the walls of the vas deferens contracts reflexively, thus propelling the sperm forward. This is also known as peristalsis. The sperm is transferred from the vas deferens into the urethra, collecting secretions from the male accessory sex glands such as the seminal vesicles, prostate gland and the bulbourethral glands, which form the bulk of semen.
