Currently, androgen replacement therapy (ART) which is provided clinically in the field of urology is a common treatment for many of the patients with LOH syndrome or gender identity disorder (GID) Female to Male (FTM). We herein describe the current situation and the challenges regarding ART for these two diseases. ART has been provided according to LOH syndrome treatment guidelines. However, the opinion of any individual clinician and/or the patient's own adherence in continuing treatment will be seen as influencing treatment decisions at any particular moment. With regard to ART in our department, cases where ART has been judged to be effective for LOH syndrome comprised 51% of cases (23 out of 45 cases). No significant difference was showen between cases which hoped treatment continuation and didn't hope. Guidelines for correctly evaluating the response to treatment and the feasibility of providing such treatment are awaited. ART provided for GID-FTM is particular in that its therapeutic effect is expected to differ greatly from that obtained when ART is provided for LOH syndrome. Order to obtain a cessation of the expected virilization and physiology of a patient's body, the hormone dose and interval need to be carefully considered. Data accumulated in our department have demonstrated that in most patients, a sufficient therapeutic effect is obtained by the administration of 125 mg testosterone enanthate for 2 weeks, and serious adverse events have not been observed. Guidelines regarding GID androgen replacement therapy are also awaited, in particular with regard to a more detailed evaluation of its predicted therapeutic effect.
