(1) When it comes to transsexuality, people usually find it very mysterious and incredible, and quite a few people find it difficult to understand. Some people are sympathetic and think it is a personal act, which is understandable. Some people think that transsexual desire stems from mental abnormality and should be treated with psychotherapy; Some people even think that transsexuality is a kind of depraved blasphemy, which is confused with "shemale". Then, why does a person with normal development germinate the desire for transsexuality, and how should society treat this phenomenon? In fact, this phenomenon has existed since ancient times and widely exists all over the world. Both men and women can appear, and their life experiences and social backgrounds are different. Medically, this phenomenon is considered to be a disease, called transsexuality, which shows the inversion of gender identity. Patients usually germinate the consciousness of gender abnormality in childhood, and have obvious heterosexual tendency in adolescence, convinced that they are born with the wrong gender and are male or female of the opposite sex. They are eager to live according to the role of the opposite sex, but they are hindered by their own bodies, so they hate their bodies, especially reproductive organs, and they are eager to change their anatomical gender through hormones or surgery. Once this requirement is not met, it will often lead to inner anxiety and extreme pain, and even self-harm or suicide. At present, the cause of sexually transmitted diseases is still a mystery. Most scholars believe that there are many reasons, such as genetic and endocrine abnormalities, especially abnormal sex hormone levels in the critical period of embryonic differentiation; According to psychological theory, sexually transmitted diseases are related to parents' parenting style and environment, such as bad psychological adjustment and parenting environment in childhood, raising children according to the opposite sex, abnormal parent-child relationship and so on. Others include brain structure theory and gene abnormality theory. For a long time, due to secular prejudice, sexually transmitted diseases have not been understood and sympathized by the society, and patients have been ridiculed and ridiculed by people around them, enduring inner anxiety and pain for a long time. They avoid crowds, don't go to bathhouses and public toilets, and constantly urge gender change. Patients with sexually transmitted diseases are mentally and intellectually normal, and generally do not use excessive behavior to harm society. Some people are unhappy all day, while others work or study hard to relieve their anxiety and even make outstanding achievements. However, the desire for transsexuality cannot be changed for life, and there is often a painful feeling that life is worse than death. Their life is a process of constantly trying to get rid of this dilemma. At present, there are psychotherapy, hormone therapy and surgical treatment for sexually transmitted diseases. However, it is generally believed at home and abroad that once the consciousness of transsexuality is formed, it is difficult to change, and the first two treatments have no clear effect. Sex-change surgery can successfully change the gender identity of patients and reduce their psychological burden, which is the most fundamental treatment. Sex change surgery includes a series of continuous treatments, from internal and external genital plastic surgery to Adam's apple, breast, tone, facial contour, hair and body shape and other related operations. Since the plastic surgery department of Shanghai Changzheng Hospital completed the first transsexual surgery in China, the hospital has successfully performed transsexual surgery for nearly 100 patients with sexually transmitted diseases and accumulated rich experience in transsexual technology. Every year, patients come to seek treatment, including many patients from Hong Kong, Macao and Taiwan and abroad. Through postoperative follow-up, most patients with sexually transmitted diseases have lost their anxiety and feel comfortable after changing their sex. Many patients got married after operation and their families were harmonious. However, experts in this hospital stressed that the conversion operation is destructive and cannot be recovered once the operation is performed. Therefore, the diagnosis of sexually transmitted diseases should be extremely strict, and the operation should be more cautious. The patient must show the certificate of the public security organ, no diagnosis of mental disorder, a written statement of the patient's medical history, the consent of his family, and a history of the opposite sex and life for more than 2 years. After strict screening, it is determined that other treatment methods are ineffective before considering sex-change surgery, and it must not be implemented rashly.
