Benign unilateral testicular hypertrophy at the onset of puberty

Abstract

Two normal boys, with no previous history, were referred at the onset of puberty for unilateral testicular hypertrophy. Radiological and biological investigations, and in one case testicular biopsy, ruled out cellular proliferation or tumor. Except for the FSH level slightly above normal in one case, no endocrine abnormality was found. This is a rare, and probably non pathologic event.
