Dear Welcome to HCM We understand your concerns I went through your details. Thickness and color of semen depends on many aspects. The color, volume, and thickness of semen may change due to so many factors. What you eat, how many times you ejaculate, low sperm count, high temperature, body hydration etc are main factors which affects the thickness of semen. You need to understand that semen is off white or white in color. If your semen is red in color, it usually happens due to prostate problems. Green or yellow tinged semen usually indicate infections. If you notice a pronounced green or yellow color, it could be due to an STD called gonorrhea. Brown or bright red semen. It is mainly due to a burst blood vessel in your prostate. Your semen color should return to normal within a couple of days, but if that s not the case, you should visit your doctor because persistent blood in seminal fluid may result from trauma, infection, and even cancer.
