After sex reassignment surgery, transsexuals (people who underwent cross-sex hormone therapy and sex reassignment surgery) tend to be less gender dysphoric. They also normally function well both socially and psychologically. Anxiety, depression and hostility levels were lower after sex reassignment surgery. They also tend to score well for self-perceived mental health, which is independent from sexual satisfaction. Many studies have been carried out to investigate satisfaction levels of patients after sex reassignment surgery. In these studies, most of the patients have reported being very happy with the results and very few of the patients have expressed regret for undergoing sex reassignment surgery.
