I might be a little concerned about his sperm being yellow. Any help would be greatly appreciated.
Semen can change color for several different reasons.
The yellow jelly-like substance that is part of the ejaculation is the sperm contained in that ejaculation. SO, the more yellow the ejaculation the more sperm are present. Some foods and drinking more water can alter the consistency and color to some degree. This information is provided for educational purposes only. Please read the disclaimer .
