Testosterone rebound therapy: a neglected modality.

A summary of the literature and a 20-year review of our own experience with testosterone rebound therapy is presented. Of 225 patients followed, 52% rebounded to fertile levels followed by pregnancy in the wives of 25%. Pregnancy occurred in 3 wives (8%) of the 38 initially azoospermic patients. There was only a 4% incidence of failure to return to at least the pretreatment sperm count following therapy, and no persistent azoospermia was observed. These results are consistent with other recent reports of several large series of patients. Proper screening and selection of patients is mandatory. Testosterone rebound is a neglected form of therapy meriting consideration in selected patients.
