Yellow to semi-yellow semen. I am a 26 yrs old male weighing about 130lbs. and my height is 6"1'. I have noticed for the past three or four years that my semen ranges from yellow to a mix of white with semi-yellow. I am not allergic to any medications and I don't feel any pain. Additionally, I have not taken any multivitamins for a while now. I urinate frequently and it's most of the time yellow (clear yellow to sometimes solid yellow, but never dark). I do notice that when I do drink lots of water or clear liquid my urine becomes clear. I do not feel any pain when ejaculating or urinating. I have not had any sexual intercourse. I do notice that I have some small tiny clear clumps (spherical shaped) in my semen. I think that is all I can think of now. Do I have something serious that I should take into account? I am thinking on visiting a doctor to check this out. Any advise or comments on the issue would be of great help. Thank you!
