Partial androgen insensitivity--are all tissues equal?

ABSTRACT

Nonaromatizable androgens, administered in high doses to an adult patient with partial androgen insensitivity, failed to result in a change in phallic size despite a clear decline in SHBG and gonadotropin levels. These findings raise the question of differential tissue sensitivity to androgens. Because ancillary laboratory testing does not predict reliably the genital response, a therapeutic trial should be advocated in such cases.
