[Leydig cell tumor of the testis presenting male infertility: a case report]

Abstract

A 33-year-old male was referred to our hospital for male infertility with painless swelling of the left scrotal content. Left high orchiectomy was performed under the diagnosis of left testicular tumor. Histologically, this testicular mass was a Leydig cell tumor. We reviewed 55 cases of Leydig cell tumor of the testis previously reported in Japan, and reported the hormonal profile in our case before and after surgery.
