<s>[INST] I recently noticed that when I ejaculated my semen was not the usual milky white but had some brown in it and appeared to be grainy. This has never happened before.  I left it for a few days but noticed the same happened again.  I am 35 and concerned that there may be something wrong. [/INST] Dear serve understand your concerns went through your details. Usually sperm is never milky white. It has to be yellowish white or shadowy white. The brownish color could be due to the presence of blood in the semen. Do not panic. That is normal. If this reoccurs, do consult a doctor in person. If you require more of my help in this aspect, please use this URL. http://goo.gl/aYW2pR. Make sure that you include every minute details possible.
