Over-masturbation, over-ejaculation, vasectomy, diabetes, and medication/streets drugs can kill the liver, adrenal and testicular functions associated with production of neurochemicals for acetylcholine and dopamine, and the conversion of cholesterol-hormones (hGH, DHEA, androstenedione, testosterone, and estrogen), resulting in prostate dysfunction and low or no seminal production (the typical result of a flooding of prolactin from your piutary glands!). Your ejaculation fluid becomes very watery, like the female ejaculation fluid ( a non-viscous, crystal clear fluid!). This is because your prostate and/or seminal vesicles produce no semen and your seminal vesicles becomes the female Paraurethral (Skene's) glands. Normally, semen consists of about 40-50% prostate's milky, slightly acid fluid containing citrate, enzymes, ProstaGlandins (more E-1 and E-3, but less E-2 or its Hydroxylased), neuro-chemicals, Minerals (about 5-6 mg Ca, 1-2 mg Mg, 1-2 mg Zn), and steroid/androgen hormones, and about 60-40% seminal vesicles' yellowish, viscous, highly-alkaline fluid fructose sugar, ascorbic acid, a coagulating enzyme and ProtaGlandins (less E-1, but more E-2). A thick, milky white ejaculation fluid (with a lightly yellowish color) is considered as a normal semen fluid. The yellowish color of the ejaculation fluid is an indicator of the mixture ratio of the seminal vesicles' secretion to the prostate secretion.
