As a medical school student I will chime in here:
Firstly when you hear about "doctors" and their discoveries and approvals and dissaprovals etc... its usually not MEDICAL DOCTORS with MD's, the reference is being made to people who hold a PhD and are referred to as doctors (doctorate). They are usually Professors and researchers involved with university programs and large firms.
Older doctors are still old school and they are really boxed into their beliefs and its not appropriate to venture outside your box. Think about when these doctors trained and how different subject matters such as penis enlargement would be looked at back then. Advocating Penis Enlargement could have a serious impact on ones image whether your a MD or a PhD.
I think in the near future Doctors will be more open towards Penis Enlargement, basically there isnt enough knowledge availible to doctors right now. We just end up seeing crazy people who ripped their penises off or caused damage through extreme girth work etc... we only see the negative.
I don't speak openly of Penis Enlargement with fellow med school students, but I'm sure if anyone comes across this site its pretty easy to believe that natural Penis Enlargement is both safe and possible if you approach it properly.
There's a lot of things out there that can be dangerous if you don't approach them properly, Penis Enlargement is just one of them, but thats no reason to push it aside.
I haven't made gains yet, but I definitely am a beliver and hopefully someday I can make some permanent gains.
PS: my post might not make any sense, I haven't slept in over 30 hours im stuffing my face with cereal trying to stay up right now<
