Reproductive outcomes of microdissection testicular sperm extraction in hypogonadotropic hypogonadal azoospermic men after gonadotropin therapy.

Gonadotropin therapy reversed azoospermia in a portion of the HH male patients studied. Of men who were still azoospermic after gonadotropin treatment, a majority could still have testicular sperm retrieved by mTESE for use in assisted reproductive technology, subsequently resulting in live births.
