CHANGE: Circumcision Guidelines Target Teenagers. “Doctors should start telling sexually active teenage boys who aren’t circumcised that if they have the surgery, they can reduce their risk of contracting H.I.V. and other sexually transmitted infections from their female partners, federal health officials propose. Similar counseling is urged for adult heterosexual men who remain uncircumcised and for expectant parents who will be making a decision about newborn circumcision if they have a boy, according to the new recommendations, proposed by the Centers for Disease Control and Prevention.”
