Non Binary
Non Binary Clinical Approach Advice should only be given where the clinician can give a clear indication to the person what physical changes will occur on hormone therapy and whether the desired mix of male and female features they desire is feasible with hormone therapy It is also important to advise the individual that none of the hormone regimens used in this field have been examined by randomised controlled clinical trials. The approach to hormone therapy also needs to be individualised In those that desire gender neutrality GnRH analogues alone may be appropriate The other approach is to allow natal hormone production to continue and attempt to suppress this sufficiently with antiandrogen therapy in a male-bodied person, or progestin or combined oestrogen/progestin treatment in a female-bodied person
Non Binary Clinical Approach This is Specialist Gender Medicine Decisions are made in the context of a multidisciplinary approach. degree of fluidity ;a clear formulation of the mix of male, female, and neutral physical features is made; significant psychological co-morbidities are excluded or managed. In all people it is important to discuss the fact that hormone therapy will impact on reproductive potential It is also good practice for the individual to be reviewed regularly by the members of the multidisciplinary team. It is important to have psychological input to the care of the individual, as the impact of the physical changes in the person on the psychological function

Long Term Outcome in Gender Dysphoria There is no difference in SMR for transmen There may be an increase in SMR for transwomen Suicide (x5.7) AIDS (x30) Cardiovascular Death (1.64) (EE users only) However Studies are confounded by changes in therapy over the last 10 years
In Summary Gender dysphoria requires hormonal therapy to achieve the secondary sexual characteristics of the desired gender Hormonal therapy carries physical risks provides psychological benefit Careful monitoring is required to prevent complications occurring Hormonal therapy in gender dysphoria is Effective Safe
