title: Preservation of fertility following doxorubicin administration in the rat.
abstract: Several hundred thousand men receive chemotherapy each year; many are sterilized by this treatment. Testicular circulatory isolation (TCI), a regional drug exclusion approach to circumvent chemotherapy-related infertility, lessens doxorubicin-induced testicular injury in the rat. We evaluated the effect of TCI on doxorubicin-induced infertility in this study. Thirty-two eight-week-old male Sprague-Dawley rats were used. Eight rats received TCI for 45 min. Eight received doxorubicin (i.v. bolus) plus sham surgery. Eight received i.v. doxorubicin given immediately after institution of TCI. Eight controls received sham surgery alone. Mating studies began 2 months later. Six of the 8 males receiving TCI alone were fertile. In the doxorubicin-treated, sham-operated group, 0 of 7 animals were fertile. In the doxorubicin-treated group which also received TCI, 2 of 7 males were fertile. In the sham-operated group, all 8 rats were fertile. This is the first evidence that regional drug exclusion technique can improve fertility in this model.
