Abstract:
:Gonadal dosimetry and spermatogenic activity was monitored in patients given radiation therapy (RT) after unilateral orchiectomy for seminoma. The RT given was, with minor variations, 3200 rad in 16 fractions in four weeks to the para-aortic and ipsilateral pelvic inguinal lymphatics in order to include the orchiectomy scar. The incidental amount of radiation to the remaining testicle averaged 78.4 +/- 7.4 rad and ranged from 32-178 rad as determined by thermoluminescent dosimetry. Induction of aspermia was documented in ten out of 14 patients who received over 65 rad to the gonad. At lower doses, aspermia may not have occurred or was of short duration. Recovery of sperm in the semen occurred in 12 patients within 30-80 weeks after start of treatment. The data suggest that the time of recovery may be dose dependent within the range of 19-148 rad. During the period of recovery, patients with oligospermic semen may be fertile and should be so advised.
