“…As the data in Table 2 indicate, many investigators have observed that earlyonset MtF transsexuals tend to differ from late-onset MtF transsexuals in other clinically important ways. For example, comArch Sex Behav (2010) 39:514-545 533 pared with their late-onset counterparts, early-onset MtF transsexuals usually display more cross-gender behavior during childhood (Docter, 1988;Dolan, 1987;Doorn et al, 1994;Laub & Fisk, 1974;Levine & Lothstein, 1981;Lundström et al,1984;Seil, 1996Seil, , 2004Stoller, 1979Stoller, , 1980; but see Person & Ovesey, 1974a, b) and less cross-gender fetishism (Burns et al, 1990;Docter, 1988;Dolan, 1987;Fisk, 1974a, b;Levine & Lothstein, 1981;Lundström et al, 1984;Person & Ovesey, 1974a, b;Seil, 1996;Stoller, 1979Stoller, , 1980; but see Doorn et al, 1994, andJohnson &Hunt, 1990). In most reports, late-onset MtF transsexuals have been described as greatly outnumbering their early-onset counterparts (Dolan, 1987;Levine & Lothstein, 1981;Lundström et al, 1984;Seil, 2004;Stoller, 1980; but see Doorn et al, 1994, andJohansson et al, 2009).…”
