Background: The prevalence of TS and other GID, as well as men/women ratio (MWR) of the pathology is the topic of a high interest for professionals in this field. The earlier data from Russia reported the MWR as 1:3 and were different from reported by other countries.

Objective: To study the current prevalence of TS and other GID in Russia.

Materials and methods: We summarized the data collected in 2006 by four Moscow clinics, experienced with GID: Research Center for Endocrinology, Moscow Center for Psychoendocrinology, Russian National Research Center for Surgery, Research Center for Psychiatry. Statistical analysis was done with STATISTICA (StatSoft Inc., USA, version 6.0) software.

Results: In 2006, there were in average 31.6 men and 30.8 women who addressed with the request of sex change for the first time. Among them, diagnosis of TS was ascertained in 16.6 (52.5%) men and in 21.3 (69.2%) women. Another GID were diagnosed in 15 (47.5%) men and 9.5 (30.8%) women. Hence, the MWR in patients with TS formed 1:1.3 and 1.6:1 in patients with other GID, respectively.

Conclusion: The new data are different from reported earlier. This fact could be explained with the lack of accurate differential diagnostics between TS and other GID. The second aspect was that the data were prevalently estimated by surgeons and included not only transsexuals, but all people with different GID who requested for surgery. The third aspect was that the more frequent surgery in transsexuals was mastectomy in female-to-male transsexuals (because vagino- or phalloplasty were more complicated and more expensive), so these patients requested to surgeons more often. Our current data reflect the situation more widely, because now we possess the data not only from surgeons, but also from endocrinologists and physiatrists.
