At the age of 35, he had undergone inguinal orchiectomy for a tumor in the left testis, and the histopathological diagnosis was seminoma, with the stage pT1, N0, M0, S0. Adjuvant chemotherapy with carboplatin was not administered postoperatively. To preserve fertility, testis\u2010sparing surgery was performed. The warm ischemic time during surgery was 32\u2009min. Histopathological examination indicated seminoma, and biopsy did not reveal germ cell neoplasia in\u00a0situ. His sexual function was preserved at 22\u2009months after surgery; however, semen analysis revealed azoospermia.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
