|
|
Formed by the ampulla of the vas deferens and the duct of the seminal vesicle
|
|
|
Measures in length from 2 to 2.5cm
|
|
|
It ends at the level of the prostatic sinuses of the prostatic urethra.
|
|
|
It ends at the level of the seminal coliculus of the prostatic urethra looking for the prostatic utricle

Detailed explanation-1: -The ejaculatory ducts enter the prostate immediately as it emerges from the seminal vesicles. Both of these ducts travel from posterior and lateral to medial and inferior. They ultimately converge at the urethra within the prostate gland on an area called the seminal colliculus.
Detailed explanation-2: -Each ejaculatory duct is approximately 2 cm in length and starts at the base of the prostate, runs along the middle and lateral lobes, and terminates at the verumontanum on each respective side.
Detailed explanation-3: -Each ejaculatory duct is formed by the union of the vas deferens with the duct of the seminal vesicle. They pass through the prostate, and open into the urethra above the seminal colliculus. During ejaculation, semen passes through the prostate gland, enters the urethra and exits the body via the urinary meatus.
Detailed explanation-4: -The prostatic urethra is the proximal portion that passes through the prostate gland. It receives the ejaculatory duct, which contains sperm and secretions from the seminal vesicles, and numerous ducts from the prostate glands.
