Copulation is a sexual intercourse between a man and a woman during which semen is released by the penis into the vagina. The male accessory glands include paired seminal vesicles, a prostate and paired bulbourethral glands. Secretions of these glands constitute the seminal plasma which is rich in fructose, calcium and certain enzymes. The secretions of bulbourethral glands also helps in the lubrication of the penis. Hence, its removal will affect copulation.
