For this study the following question should be investigated:
Is the incidence of phantom pain and local chronic postsurgical pain lower in sex reassignment surgery from male to female compared to inguinal tumor orchidectomy?

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The sex reassignment surgery is expressly desired, the amputated tissues are rejected or perceived as not belonging to the patient's own body and thus do not appear as a loss. The group of patients with tumor orchidectomy acts as a control group.
In addition to the incidence of phantom pain and chronic local postoperative pain in comparison between the two groups, the secondary objectives of the study were defined as the occurrence of phantom pain, the type of pain and the intensity of pain.
Two patient groups were compared, the group after sex reassignment surgery (GAC) and the group after inguinal orchidectomy for testicular tumor (ORC).
A total of 265 transgender women were written to, 46 of whom had undergone surgery in Tübingen and 219 in Munich. The operations took place between 2002 and 2014.
For the group of patients after orchidectomy, 158 men who had undergone surgery in Tuebingen between 2010 and 2014 were contacted by letter.
The pseudonymization was done with a combination of letters and numbers, which were created with a key generator program.
The patients received a questionnaire divided into several categories, these categories were questions on demography, pre- and postoperative pain as well as phantom pain, pain processing, quality of life, sex life and urological questions.
