I would disagree with you there, UTI's are fairly common, for 2018: About 2,320 new cases of penile cancer diagnosed, about 380 deaths from penile cancer. vs FGM:
Typically carried out by a traditional circumciser using a blade, FGM is conducted from days after birth to puberty and beyond. In half the countries for which national figures are available, most girls are cut before the age of five. Procedures differ according to the country or ethnic group. They include removal of the clitoral hood and clitoral glans; removal of the inner labia; and removal of the inner and outer labia and closure of the vulva. In this last procedure, known as infibulation, a small hole is left for the passage of urine and menstrual fluid; the vagina is opened for intercourse and opened further for childbirth.
The practice is rooted in gender inequality, attempts to control women's sexuality, and ideas about purity, modesty and beauty. It is usually initiated and carried out by women, who see it as a source of honour and fear that failing to have their daughters and granddaughters cut will expose the girls to social exclusion. Adverse health effects depend on the type of procedure; they can include recurrent infections, difficulty urinating and passing menstrual flow, chronic pain, the development of cysts, an inability to get pregnant, complications during childbirth, and fatal bleeding. There are no known health benefits.
Common short-term complications include swelling, excessive bleeding, pain, urine retention, and healing problems/wound infection. A 2014 systematic review of 56 studies suggested that over one in ten girls and women undergoing any form of FGM, including symbolic nicking of the clitoris (Type IV), experience immediate complications, although the risks increased with Type III. The review also suggested that there was under-reporting. Other short-term complications include fatal bleeding, anaemia, urinary infection, septicaemia, tetanus, gangrene, necrotizing fasciitis (flesh-eating disease), and endometritis. It is not known how many girls and women die as a result of the practice, because complications may not be recognized or reported.
