title: Indication of varicocelectomy in the era of assisted reproductive technology: prediction of treatment outcome by noninvasive diagnostic methods.
abstract: Of 103 patients who underwent varicocelectomies, 87 underwent all the diagnostic methods: color Doppler ultrasonography (DOP), scrotal deep body temperature (DBT), and scrotal scintigraphy (SSG). Total motile sperm (TM) was calculated. The positivities of DOP, DBT, and SSG were 67, 51, and 90%, respectively. In the patients <30 years old, TM increased in the DBT-positive group. In older patients, positive for DBT indicated poor improvement of TM, whereas positive for DOP indicated better response in the group. Patients older than 30 years and positive for DBT, but not DOP, should be counseled directly to receive intrauterine insemination or in vitro fertilization/intracytoplasmic sperm injection.
