balanitis most often occurs in men and boys who have not been circumcised (had their foreskin surgically removed) and who have poor hygiene. inflammation can occur if the sensitive skin under the foreskin is not washed regularly allowing sweat debris dead skin and bacteria to collect under the foreskin and cause irritation. the presence of tight foreskin may make it difficult to keep this area clean and can lead to irritation by a foul-smelling substance (smegma) that can accumulate under the foreskin. other causes of balanitis may include: dermatitis /allergy. dermatitis is an inflammation of the skin often caused by an irritating substance or a contact allergy. sensitivity to chemicals in certain products -- such as soaps detergents perfumes and spermicides -- can cause an allergic reaction including irritation itching and a rash. infection. infection with the yeast candida albicans (thrush) can result in an itchy red spotty rash. certain sexually transmitted diseases -- including gonorrhea herpes and syphilis -- can produce symptoms of balanitis. in addition men with diabetes are at greater risk for balanitis. glucose (sugar) in the urine that is trapped under the foreskin serves as a breeding ground for bacteria.
