hii,welcome to health care magic, Consistency of semen isn t very consistent; you ve probably noticed that the thickness of your ejaculate can vary from day to day. This is because the quality of the fluid is very susceptible to a number of factors. Diet, exercise and frequency of sex can all dictate how thick or watery your emissions are, as can the tightness of the clothes that you wear (tight clothing will increase body temperature and can thus impact sperm motility. This is best evaluated by a urologist. He can check this somewhat by a digital rectal examinatoin but probably will need to do a transrectal ultrasound of the prostate and seminal vesicles to be more accurate. Both of these are quite simple to do with minimal discomfort. Sperm count (over 20 million per cc or 40 million total is normal).
