The prostate gland is an organ present only in males.  It lies just below the bladder, and  the ''urethra'' (the tube that carries urine) runs directly through it (although in some other mammals, the urethra runs around, rather than through, the prostate<ref>R. Ganzer et al, "Muscle systems of the lower urinary tract of the male rhesus monkey (Macaca mulatta): histomorphology and 3-dimensional reconstruction," ''J.

It is dependent on testosterone and other male hormones.
