The Male Genital Organs

The male genital organs (Organa genitalia masculina) are: (1) The two testicles, the essential reproductive glands, with their coverings and appendages; (2) the vasa deferentia, the ducts of the testicles; (3) the vesiculæ seminales; (4) the prostate, a musculo-glandular organ; (5) the two bulbo-urethral (or Cowper’s) glands; (6) the male urethra, a canal which transmits the generative and urinary secretions; (7) the penis, the male copulatory organ. The vesiculæ seminales, the prostate, and the bulbo-urethral glands discharge their secretions into the urethra, where they mix with the seminal fluid secreted by the testicles; hence they are often termed the accessory sexual glands.
