The city of Madrid hosted the Second European Congress on Transsexuality, which offered a forum on many of the medical issues associated to sex reassignment surgery. Many lightly affirm that, this procedure should be performed, given that it is technically possible to do so. Regardless of the objective ethical reasons involved, the procedure also creates medical problems that are not always taken into consideration. For instance, all persons who undergo these procedures must receive hormone therapy for the rest of their life, which could give rise to certain medical conditions. This includes decreased bone quality resulting from the extraction of the patient’s gonads. For these patients, bone density must be monitored after the procedure, as in the case of menopausal or andropausal individuals. Other conditions that may arise include cardiovascular problems or adverse effects on the skin (Diario Médico 8/14-07-2013).
