If you decide to participate, we invite you to have a physical examination and laboratory investigations to evaluate long-term effects of your hormone therapy. We will also gather important data of your medical history. Furthermore, we will ask you about your general and psychological well-being, your previous and current everyday experiences with your condition, potential sexual complaints and your experiences and satisfaction with previous and actual health care and treatment. Moreover, your views on the naming of your condition will be gathered and taken into account as we know that the medical umbrella term disorders of sex development (DSD) is not appreciated by many persons.

All results of the medical exam will be reported back to you and you may receive clinical consultation and advice, should you be interested.
