I have some similar symptoms as described in the OP. I have skimmed through the whole thread but it does not seem to be any recommendation for a specific doctor or clinic to visit in Bangkok.
I really do not want to start with TRT if it is not absolutely necessary so I would like to consult a specialist doctor in the area and have some blood tests to find out about the underlying reasons for my symptoms. I would appreciate any recommendation for a reputable doctor or clinic in Bangkok.
