}}</ref> In January 2007, The [[American Academy of Family Physicians ]] (AAFP) stated "The effect of circumcision on penile sensation or sexual satisfaction is unknown. Because the epithelium of a circumcised glans becomes cornified, and because some feel nerve over-stimulation leads to desensitization, many believe that the glans of a circumcised penis is less sensitive. [...] No valid evidence to date, however, supports the notion that being circumcised affects sexual sensation or satisfaction."<ref name="AAFP"/> Conversely, a 2002 review by Boyle ''et al.'' stated that "the genitally intact male has thousands of fine touch receptors and other highly erogenous nerve endings&mdash;many of which are lost to circumcision, with an inevitable reduction in sexual sensation experienced by circumcised males." They concluded, "intercourse is less satisfying for both partners when the man is circumcised".<ref>{{REFweb
