you can obtain the Dr. Med title in Scandinavian countries by publishing 5 articles progressively elucidating a larger problem.
Phd standard if a little different internationally, with US having the most lengthy and thorough education span over 5 and more years, doing multiple lab rotations. In Scandinavia its usually 3 years with 3 5 pubs in the same field.

Dr. med in Germany is a very low title, comprises a year or two of lab work if I were correct. My PI who happens to be a Dr. med from denmark often frequent germany and she occasionally gets this remark of Im quite surprised that someone with your credential is ONLY a dr. med.
