and I can tell you being from a family of specialist doctors the medical care is outstanding. I also met Dr Le Roux with a view to doing DE there 2 years ago ( we eventually cycled in Argentina) and , although I am now in 2ww and awaiting outcome , in a way regret not going to SA - it was just way more expensive for us than Argentina.
I would trust the clinic there completely. I also had some dealings with the donor agencies there- there are 3 I know of- and they are great. Cape Town , my home town, is a fab place to visit- gorgeous and very European. THe other advantage is you are in an English speaking country ( we had some language barriers in Argentina)
Good luck .
