Sometimes men pass a whitish fluid with urine or whilst straining at stools. The belief that this fluid is semen/dhat is called the 'Dhat' syndrome. This is not a disease and it would not be inappropriate to say that it exists only in the mind of the beholder. The physiological sphincter at the neck of the urinary bladder always remains closed and opens only when one is passing urine. Thus, it ensures that normally urine and semen do not mix i.e. normally one cannot pass semen and urine together. Sometimes, a physiological alteration in the urinary solution may change the appearance of urine, making it whitish which is mistaken to be semen by mistaken to be semen by misinformed individuals. In reality, the whitish discharge is largely the secretion of the urethral and prostate glands. When a man squats in the toilet and exerts a little pressure, the pressure is relayed from the rectum to the urethra and a few drops of sticky white secretion accumulate, coalesce and trickle down. The phenomenon is akin to there being ten drops of perspiration and on being joined by the eleventh trickle down . In my opinion, this misconception is prevalent in our country because of squatting toilet habits, as people tend to look down and see the sticky substance which they presume to be semen. In developed countries , most people use western style commodes, so they look straight ahead. Hence, what the eyes do not see, the mind does not perceive!
