What is the role of prostate glands?
The prostate gland is located just below the bladder in men and surrounds the top portion of the tube that drains urine from the bladder (urethra). The prostate’s primary function is to produce the fluid that nourishes and transports sperm (seminal fluid).
Where are the male ejaculatory ducts?
On each side of the prostate gland (in the male reproductive system) is an ejaculatory duct. Each ejaculatory duct is about two centimeters in length and is created when the seminal vesicle’s duct merges with the vas deferens.
