Dear Editor,rnI have read with interest and some amazement the article of Dr.Wachtel and coworkers describing a hypothetical benefit of male circumcision (MC) on prostatic cancer (PC) mortality rates.1 The issue is old and going back to 1951.2 Unfortunately,the authors have omitted the literature during the last 65 years which was not able to prove that MC would protect against PC mortality.3-9 Wachtel and coworkers draw their study data from different heterogeneous sources and different years without testing if they describe items of comparable population groups.
