Hello,
Semen contains fructose and a
substance that causes the semen to clot (become sticky or
jelly-
like) after ejaculation. This is normally found and hence the semen appears jelly like. If you notice change in the color of semen like red, brown or yellow, then it needs to be evaluated by a urologist.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided.
