Foul smells are usually associated with - Infections of the prostrate gland or other organs of the male reproductive system. - If the smell is accompanied with a change in color of the ejaculate to red, brown, yellow or green, you definitely have an infection. It is time to consult a physician and get a diagnosis done. Do the following test: Blood: CBC, ESR, glucose Urine routine and microscopic examination. For prostate: PSA Take following advice: 1. Use condoms 2. Maintain personal hygiene, wash penis area after sex, remove segma that is deposited under foreskin 3. spread a sweet aroma in the bedroom by lighting scented candles or using incense and room sprays.
