[Testicular seminoma revealed by hypergonadotropic hypogonadism].

We report the case of a 39-year-old patient who complains about loss of libido and erectile dysfunction. Hormonal diagnosis revealed hypergonadotropic hypogonadism suggesting a primitive testicular cause. Testicular examination, testicular ultrasounds and abdomen-pelvis CT scan made it possible to suspect a right testicular tumor. A stage I seminoma was confirmed at orchiectomy. Testicular cancer is the most common cancer in men before the age of 35. Most testicular tumors initially present with a scrotal mass: a testicular tumor should not be ignored in a patient with hypergonadotropic hypogonadism.
