Hello
I have been reading a lot about colon vaginoplasty in this groups and other sources and for what I understood, most people see this procedure as been something to use in case the penile inversion having complications. I heard lots of women complaining about the odor, that is really unpleasant, and other disavantages, and that penile inversion should be the first choice, or srs with skin graft. For what I´ve been researching, the only surgeon in Brazil that worth trying is Marcio Littleton, who uses a techinique taught by Dr João Décio Ferreira, that is pretty much the colon vaginoplasty using only the mucosa. So, because I was so insecure about the smell, I wrote him an e-mail, questioning that issue, he said (I'll try to translate as better as I can):
This techinique was criated in 1971 for women with vaginal atresia. In this case we don't use a portion of the bowel, as it is used in the colon graft srs, where the natural anaerobic bacterial flora is somewhat preserved, causing the semell. What we use is only the mucosa, and we reject the other parts. The microbiota of this segment ismade of Gram negative bacterias, so does not produce odor. The vaginas made of skin have odor because of queratin's putrefation. In the srs with mucosa graft, the smell will only occur if the patient has candidiasis or bacterial vaginosis, cause it functions like a normal vagina. In the other techiniques the vaginal canal is very different and doesn't work as a normal vagina.
I don't know if I should believe him, since he has a partial opinion. After all he want's to perform the surgeries to get paid.
