The two ejaculatory ducts are formed by the union of the vas deferens and the duct of the seminal vesicle. Each is about 1 inch long and pierces the posterior surface of the prostate to open into the prostatic part of urethra. The opening of each ejaculatory ducts lies close to the margins of the prostatic utricle.
Ejaculatory ducts serve as route for the seminal fluid to be drained into the urethra. They don’t have any secretion of their own.
