摘要: 本文从三个方面探索了爱普列特( Epristeride) 的生殖毒性。SD 大鼠口服9 周爱普列特后合笼,观察交配率、怀孕率和胎仔的发育情况;小鼠口服高剂量爱普列特后对精子形态的影响;体外电刺激对小鼠输精管收缩的影响。结果表明高剂量虽使大鼠怀孕率略有下降,小鼠精子的形态有所影响外,但统计无显著性差别,其他指标均属正常。提示爱普列特有一个较宽的不影响生育力的剂量范围。

Abstract: Epristeride is an uncompetitive 5α2reductase inhibitor , using for t reatment of benign prostatic hyerplasia. Fertility study on epristeride was carried out in SD rat s. Epristeride was given to male rat s for 9 weeks before mating performance at dose level of 3 ,15 ,75 mg/ kg. Body weight gain and food intake were similar to cont rol. No influence of epristeride in mating performance was observed , but showing slight less of pregnancy rate. No external , visceral and skeletal anomalies were found in fetuses. A little bit of increase in abnormal sperm morphology was observed f rom epristeride2t reated mice at high dose , but there is no statistical significant . Epristeride did not inhibit the elect rically evoked cont ractions of mouse vas deferens. In conclusion ,there is a wide range of safety in reproduction for Epristeride.
