The prostate is an important genital organ, possessingthe triple function: a, of expulsion of semen by means FUNCTION. IS of the rhythmical contraction of its muscular fibers; b, ofbeing the nerve center of the orgasm; c, of secreting,through its glandular structure, a fluid essential as avitalizing agent to the spermatic germs. It is in this gland that the pleasurable sensation of theorgasm is located; the sensation being synchronous withthe expulsion of semen. It is by this gland that thephysiological impulse to gratify animal nature is indi-rectly exerted through the sympathetic and cerebro-spinalnerve centers.
