seminal vesicles
The accessory sex glands (such as seminal vesicles, prostate, and Cowper's glands) contribute fluid to semen. The seminal vesicles contribute to about 60-70% of the seminal fluid as they secrete their alkaline, white-ish, yellow, viscous material (which contains fructose, prostaglandins, and ascorbic acid). So, the seminal vesicles are the main contributor to the alkaline pH of semen. The prostate gland, however, also secretes materials (such as citric acid, fibrinolysin, prostatic acid phosphatase, and serine protease) which will make up about 25% of seminal fluid. Thus, the prostate gland also contributes to the alkaline pH of semen, but the seminal vesicles are the major players.
