If you look in the achieves I gave you the name and link of where to buy the book when I initially answered your post. "There is an excellent book out A Parents Guide to Congenital Adrenal Hyperplasia
C. Y. Hsu and Scott A. Rivkees, M.Dhttp://www.authorhouse.com/BookStore/ItemDetail.aspx?bookid=27871 which I am sure you would be able to buy from South Africa - this explains and tells you everything about CAH."
You can buy this from South Africa as the paediatrician my son was under there has recently purchased copies after I sent him one.
