The ejaculatory ducts are two hollow tubes located on each side of the midline within the male reproductive system. Each duct is formed at the base of the prostate gland by the union of the ductus deferens and the excretory duct of the seminal vesicle.123

Measuring approximately 2 cm in length, these ducts pass between the lateral and median lobes of the prostate to reach the floor of the prostatic urethra. Their openings are situated on either side of, or just within, the opening of the prostatic utricle on the urethral crest. Functionally, they serve to mix sperm with fluids secreted by the seminal vesicles and transport the resulting semen into the urethra.21
