The salt-wasting and simple virilizing types are sometimes grouped together as "classical".

Thus, one of the most pressing questions is whether the clitoris can be enlarged without causing other unwanted virilizing effects.

This protocol made it possible for female athletes to receive high testosterone dosages and still pass doping tests, but it had strong virilizing effects, in particular hirsutism and voice changes.

To take advantage of its virilizing effects, testosterone is often administered to transsexual men as part of the hormone replacement therapy, with a "target level" of the normal male testosterone level.

The growth problem is even worse in the simple virilizing forms of CAH which are detected when premature pubic hair appears in childhood, because the bone age is often several years advanced at the age of diagnosis.
