Circumcision Not Recommended
Pathological phimosis—more accurately called preputial stenosis and sometimes described as acquired phimosis—occurs in less than one percent of males, is often misdiagnosed, and has many causes. Lichen sclerosus et atrophicus (LSA), thought to be the same condition as balanitis xerotica obliterans (BXO), is regarded as a common cause of pathological phimosis. Other causes include scarring caused by forcible retraction of the foreskin and balanitis. Males with phimosis have masturbation practices that differ from the usual back-and-forth gliding of the foreskin that mimics sexual intercourse.
Some studies have found phimosis to be a risk factor for urinary retention and cancer of the penis. Common treatments include steroid creams, preputioplasty, manual stretching, and circumcision.
Using circumcision to avoid phimosis is not advised. Less than one-tenth of one percent of intact adolescent boys per year will develop pathological phimosis, while the risk of post-circumcision phimosis due to adhesions is twenty-five times higher.
