Light micrograph of a section through a normal human prostate gland. The prostate is a gland that is a part of the male reproductive apparatus. It is located under the bladder and around the ejaculatory canals. In conjunction with the seminal glands (or vesicles), it produces the seminal plasma out of which sperm develops. This plasma facilitates movement in the sperm. Prostatic secretions are regulated by the androgens (male hormones). The secretions include fibrinolysin, which liquefies coagulated semen in the vagina
