The species most often found were Bacteroides ureolyticus (n = 10 women), Corynebacterium sp. (n = 12), Enterococcus faecalis (n = 13), Mobiluncus curtisii

(n = 10), Staphylococcus Inositol oxygenase epidermidis (n = 19) and Streptococcus anginosus group spp. (n = 16). The neovaginal microflora of only one woman contained lactobacilli. Neisseria gonorrhoeae could not be not cultured. There was no correlation between dilatation habits, having coitus, rinsing habits and malodorous vaginal discharge on the one hand and the presence of a particular species on the other hand. There was however a highly significant correlation between the presence of E. faecalis and sexual orientation: in heterosexual transsexual women (having a male partner) E. faecalis was present in 78.6% while it was only present in 14.2% of homosexual transsexual women and in 12.5% of bisexual transsexual women (p = 0.003). Equally there was a significant correlation between E. faecalis and the occurrence of regular coitus with a male partner: in those having regular coitus E. faecalis was present in 75% while in only 25% of those not having coitus (p = 0.027). Detection by species specific PCR DNA extracts of the 50 neovaginal samples were amplified with 16S rRNA gene based primers specific for A. vaginae, G. vaginalis and Mobiluncus curtisii. Respectively 58% and 30% of the samples were PCR positive for A. vaginae and G. vaginalis (Table 2), with 24% of the samples positive for both species and 36% negative for both species.
