My husband has a brownish color to his semen with a foul odor, what could that be

It could be he tore a blood vessel, the brown color is old blood... don't worry, though. It should heal, but maybe you should just go see a doctor.

Does semen have a typical look, smell and taste?

Semen usually appears as an opalescent white fluid that gets clear and runny within minutes after ejaculation. Often, semen has an odor that resembles chlorine. And the different parts of semen have different tastes. "For example, the component from the seminal vesicle, which is high in fructose [sugar], will be slightly sweeter than the rest of the fluid," Dr. Lowe explains. That said, semen characteristics do vary from person to person, month to month. Small changes in color, smell or taste are not necessarily cause for alarm, adds Dr. Goldstone.

Blood in your semen can signal a broken blood vessel, which may result from the force of your ejaculation. If this is the case, the blood will usually subside after a couple of days. You should contact your doctor if your semen continues to look brown or red, because this may signal an infection of the prostate or seminal vesicle, says Dr. Lowe. A yellowish or greenish discharge from the urethra is frequently a sign of gonorrhea, a sexually transmitted disease (STD) that can be cured with antibiotics.

Also consult your doctor if your ejaculate has a strong, foul smell. This, too, could be a sign of a prostate infection.
