Dr. Sawyer: If the woman has a yeast infection at the time of sex, there’s a great chance the man will become infected. Yeast in a man is commonly called “jock itch,” and is a fungal infection that results in an itchy red rash in the scrotal sac and in between the legs. The infection in the male can easily be treated with an over-the-counter medication, like Lotrisone. If you’re a woman who keeps getting infected with yeast, have your boyfriend checked…he could be re-infecting you. Oh, by the way, you can get yeast infection of the throat, so watch out for oral sex!
