拟除虫菊酯类农药的男(雄)性生殖毒性研究进展

Progress in Studies of the Male Reproductive Toxicity of Pyrethroid Insecticides

拟除虫菊酯作为一种新型农药,由于其高效、低毒而替代有机氯类农药被广泛应用。近年来,越来越多的证据表明,拟除虫菊酯类农药能够降低精子密度和活力,诱导精子头部畸形,增加畸形精子数量,损伤精子DNA以及诱导精子DNA的非整倍性,并影响生殖激素水平,具有生殖毒性。本文从动物实验和人群研究两个方面,就几种近年来使用较广泛和研究较多的拟除虫菊酯类农药杀虫剂对男(雄)性生殖毒性的研究最新进展进行了综述,以探讨拟除虫菊酯类农药杀虫剂对男(雄)性生殖毒性的作用机制。

As a new type of pesticides and because of their high performance and low toxicity, pyrethroid insecticides are widely used in place of organochlorine insecticides both in agriculture and in the home. In the recent years, more and more evidence indicates that pyrethroid insecticides can reduce sperm count and motility, cause deformity of the sperm head, increase the count of abnormal sperm, damage sperm DNA and induce its aneuploidy rate, as well as affect sex hormone levels and produce reproductive toxicity. The present article reviews the advances in the studies of male reproductive toxicity of pyrethroid pesticides by experiment in animals and human population, discusses the mechanism of male reproductive toxicity of pesticides and raises some problems concerning the evaluation of human reproductive hazards.
