Candida naturally live in all of us – in the digestive tract, mouth, and throat. It only becomes a problem when there is overgrowth. Male Candida usually occurs as a skin rash on arms, face, underarms, groin, or the genital region. The sore irritated rash is itchy with tiny blisters. The CDC has a good write-up on Candida.
Quote: Middleton and colleagues' are to be congratulated in demonstrating that there is no conclusive link between overgrowth of intestinal Candida albicans and the symptomatology of irritable bowel syndrome (IBS).
Sadly, I suspect that the popular health magazines and alternative practitioners who persuade patients that these symptoms are directly linked to the pseudoscience of 'leaky bowels' and Candida toxins' are unlikely to alter their views.
Here is link to an abstract of the study the author was referring to in the letter. The connection between IBS and Candida was dispensed with about 15 years ago.
The role of Candida overgrowth in men is even more tenuous
