Seminal vescicles are sac like structures which lies posterior to bladder.They join with vas deferens to form ejaculatory duct.It contains a whitish Brown viscous fluid that contain sugars ,for providing energy and prostaglandins,for mobility and proteins for coagulation reactions after ejaculation.

Prostate is a dense structure located inferior to bladder.Ducts from prostate empty into prostatic urethra.The secretions are white,milky and alkaline in nature,which helps in motility of sperm.These secretion is released when semen enters urethra.

Bulbourethral glands are small,pea like shape and is located near the base of the penes.In response to sexual stimulation,bulbourethral secrete an alkaline mucus like fluid.It neutralizes the acidity of urine in urethra and acidity of vagna ,also provides a lubrication in the tip of penes during sexual intercourse.
