Summary: Testicular damage due to cytotoxic drugs and recovery after cessation of therapy. Testicular function was assessed in 32 patients who received standard chemotherapy regimens for disseminated lymphomas. Thirty‐one had evidence of germ cell damage, as assessed by the finding of azoospermia and/or high plasma levels of follicle‐stimulating hormone (FSH). In addition, five patients had persistently low plasma testosterone levels associated in three with elevated plasma luteinising hormone (LH) levels. Reproductive function did not recover in any patient while chemotherapy continued. Cessation of therapy was possible in 16 patients with prolonged remissions of disease. Among these, recovery of germinal epithelium differed greatly between the cyclophosphamide / vincristine / prednisone treated group and the mustine I procarbazine / vincristine/prednisone treated group. Seventy per cent of the former patients had evidence of recovery after 34 months of follow‐up while only one (17%) of the latter had begun to recover at 52 months post‐therapy. Serial measurement of plasma FSH levels proved useful in predicting likely recovery of spermatogenesis.
