title: [Questionnaire survey in Japan for sperm cryopreservation before chemotherapy ].
abstract: Questionnaires were mailed to 104 urological departments in universities, colleges, and cancer centers in February 2008. Ninety institutions returned answers to the questionnaire. Sperm cryopreservation before chemotherapy was performed in 24 institutions (26.7%) mainly in the gynecological department, whereas the others introduced the candidates to other institutions including private hospitals and clinics. Fifty-eight institutes gave information about fertility preservation routinely to young patients with testicular cancer before chemotherapy. Urological doctors in 57 institutions (63%) had no experience in consultation of patients with hematological/pediatric malignancies for fertility-preservation. Among 24 institutions performing sperm cryopreservation before chemotherapy, 18 preserved motile sperm even if during chemotherapy, as well as before chemotherapy but 2 institutions replied that patients during chemotherapy were contra-indication for sperm cryopreservation. For the patients with azoospermia, 2 institutions replied they tried to preserve testicular sperm before chemotherapy. The fee for sperm cryopreservation was free in 10 institutions. This nation-wide questionnaire survey clarified that the systems and indications for sperm cryopreservation before chemotherapy were different among institutions.
