The prostate is an important gland located between the penis and bladder. It sits just to the front of the rectum. The urethra, which carries urine from the bladder out of the body, runs through the center of this walnut-sized organ. Primarily, this gland serves the function of secreting fluid that nourishes sperm and keeps it safe. 1
The secretions of the gland, known as prostate fluid, is a part of the seminal fluid that is ejected during ejaculation. The prostate muscles will help eject the seminal fluid into the urethra. The muscles themselves weigh about twenty grams and surround the urethra just below the bladder.
This last prostate image shows the back view of the prostate gland. This perspective reveals the ampulla of the ductus deferens (the ductus carries sperm from the testes-balls to the prostate gland, adding semen from the ampulla) where more fluids are added from the seminal vesicles.
