20,000 nerve endings

How did Fleiss come to this number, which is nowhere documented?: Reorder subsection.
1995, in the film "[[Whose Body, Whose Rights?]]"<ref name="WhoseBody" /> starting from Montagu's description of the number of nerve endings in normal skin, the number of nerve endings in the [[foreskin]] was calculated as follows: “15 square inches comfortably fits 15 quarters. This analogy helps us to understand that the adult [[foreskin]] contains … over 1000 nerve endings …" (15 × more than 50 = more than 750), which NOHARMM supplements to "Since Dr. Taylor's research suggests that the [[foreskin]] is '''more densely enervated than "normal" skin''', a circumcised man likely loses many times more than 1,000 nerve endings.”<ref name="circumcisionharm" /><sup>b</sup>
==== The “ridged band" ====
In 1996 the article by the Canadian pathologist [[John R. Taylor]] et al.<ref name="Taylor" /> about the “ridged band” of the [[foreskin]] had appeared. Taylor reported, that the encapsulated nerve endings<ref>Nerve endings can be divided into types with or without end corpuscles (corpuscular/encapsulated or free nerve endings). “… the free nerve endings (FNE) … do not seem to have any part in fine touch sensation (they are innervated by unmyelinated axons which conduct too slowly, don’t have specialised end corpuscles to transduce vibration, etc. and have a high threshold, all of which prevent the conduction of fine touch).” [[Ken McGrath|McGrath]], Fn 29b</ref> of the [[foreskin]] are concentrated in the “ridged band” and thus are distributed very differently. In his article, Fleiss also mentions the "ridged mucosa" and calls Taylor as a source. He therefore knew of Taylor’s work.
==== Nerve endings in the [[foreskin]] / 1cm² ====
In 1997 Fleiss knew from Bazett et al. (1932).<ref name="bazett1932" />,<ref name="JAMA" /> that they had counted 212 nerve endings within a 1cm²-piece of a single [[foreskin]] tissue (Table 1, p. 492). Now it is obvious that Fleiss reckoned similarly therewith and with the [[foreskin]] size of 15 sq.inch = 96.8 cm² (or with 8×13 = 104 cm²): 96.8 cm²×212 nerve endings / cm² = 20,522 nerve endings (or 104×212 = 22,048; short: 100×>200= >20,000). So he obviously came to "more than 20,000 nerve endings".
