Nowadays, sex reassignment surgery techniques have become rather popular among transsexuals in different countries of the world. For better understanding of these techniques origins let`s have an overview of sex reassignment surgery history Thus, the first sex reassignment surgery techniques were officially performed in Japan. The surgery was undergone for the transsexual (female-to-male) person in 1998. The second sex reassignment surgery to be performed was male-to-female surgery in 1999. It`s a common knowledge that sex reassignment surgery techniques have become possible since the rapid advances in knowledge of plastic surgery techniques and sex hormones in the late 1980s. Speaking about the mentioned cases it`s necessary to admit that for female-to-male surgery a two-stage conversion was known to be applied. And in the first surgery such sex reassignment surgery techniques as hysterectomy, metoidioplasty, mastectomy, colpectomy and salpingo-oophorectomy were applied. The second stage was free flap phalloplasty. So, male-to-female surgery is considered to be pretty simple comparing to the female-to-male one. The operation of 1999 included only one-stage neovaginoplasty, which was performed with a penile skin inversion technique. Speaking about a sex reassignment surgery description and origins, the first operations performed in Japan received a wide acclaim through the whole country and there was almost no public criticism. So, the first sex reassignment surgery was considered to be the turning point of the plastic surgery history and medicine development on the whole. Unfortunately, the ideal sex reassignment surgery hasn`t yet been described in the medical practice. But at the same time there are several various sex reassignment surgery techniques proposed in specialized literature are similar. As a matter of fact, today there are several outstanding surgeons who perform sex reassignment surgeries in the world. But none of them can perform the surgery unless the patient meets all the necessary requirements. For example, as a rule, the person who is willing to undergo a sex reassignment surgery must first try living for at least a year in another gender role full-time, proper engagement in certain hormone therapy for at least a year, having the recommendation of therapist or psychologist (after some series of sessions), having a recommendation from the psychiatrists with the proof that sex reassignment surgery will not be contrary to the patient`s mental health. It has become evident that the public interest to modern sex reassignment surgery techniques us steadily increasing year by year. That`s why some acknowledgements regarding this issue become established. By the way there`s yet no policy regarding legislation and health policy for the people who had this procedure. However, despite these and other problems associated with sex reassignment surgery techniques they are still considered to be prominent in transsexualism treatment all around the world.
