Doing this cleans all bacteria and anything dried on the penis. Then they usually ask you to do a mid-stream catch sample. This means you start to urinate into toilet and then hold it in for a few seconds and keep urinating into the bottle to fill the sample bottle.
adviceman49 answered Monday February 18 2013, 6:17 pm: Everyone masturbates or at least 85% of us according to a recent survey. Any sperm that may not fully ejaculate will be expelled the first time you urinate after you have masturbated so there is almost a zero chance of any sperm being in your urine. Just to be safe don't masturbate just before going for your urine test.
As I said masturbation is normal and just for the sake of argument if they were to find some sperm in your urine the doctor would most likely not be concerned unless the problem they are checking for is in someway related to prostrate problems. But if this is a routine pee test for school athletics or a possible bladder infection the doctor would not be concerned.
You would be considered a normal teenage male and the doctor would not and cannot say anything to your parents as if you are over 14 years of age. Anything to do with your reproductive system is protected by law with full medical confidentiality. This is a Federal Law called HIPPA and there are Jail terms for any doctor who violates you medical confidence in this area. Only you can release information regarding medical issues with your reproductive system and this must be in writing to the doctor. You are in complete control and cannot be forced to undergo any procedures that are not life threatening.
