menotropins and Dysgerminoma

Blood samples for hormone analysis were obtained 5 to 20 years post-therapy from 12 men with testicular tumors who were originally treated by unilateral orchiectomy followed by abdominal and/or pelvic irradiation. In nine patients (75%) the levels of FSH and LH, and in one patient (8%) the testosterone values, were outside the ranges found in age- and sex-matched controls. From this retrospective study we conclude that, even when the remaining testis is kept outside the field of radiation, significant radiation damage occurs, mainly through scatter. This damage is more likely to occur if the hemiscrotum is irradiated. Methods of shielding are available to reduce the dose received by the contralateral testis.
