The male accessory glands include paired seminal vesicles, a prostate and paired bulbourethral gland. Secretions of these glands constitute the seminal plasma which is rich in fructose, calcium and certain enzymes. Secretions of prostate glands are alkaline in nature which helps in the neutralization of acidity of the vagina. The secretions of bulbourethral glands help in the lubrication of the penis.
