hormonal test

The best indication to know if you have a physical-medical OR psychological problem causing your erection problem is answering a simple question: do you have an erection at any time? morning erection? when watching TV OR at any other situation? If you do have an erection but not when you need it, that an indication that you dont have any medical problems (hormonal OR other) but your erection problem is on psychological basis (like fear of falure OR performance anxiety). In that case I reccomend psycho-sexual treatment. If you don't have an erection at any time you shoud do do night erection test - consult your doctor where AND how to do it. Hormonal test is also reccomended in this case although hormonal problems are not very common but it is an easy blood test which can be done in Kupat Holim.
