Please can a semen and urine(separately tho)inside a tube useful for test after 6 or 12hrs?I'm due to take both tomorrow morning for test but if I wait till morning I don't think there will be space/privacy to jerk off inside the tube, only chance I got is now or midnight.

Doctors on here please will the semen and urine still useful for test even after 6 or 12hrs? Forgot to ask the doctor about this!!

Help biko
