[Toxicological characteristics of plant growth regulators and their impact on male reproductive health].

ABSTRACT

Plant growth regulators (PGRs) have similar physiological and biological effects to those of plant hormones, and therefore are used widely in agroforestry. The residues of PGRs in agricultural products are seriously detrimental to human health because they have been found with hepatotoxicity, nephrotoxicity, genotoxicity, neurotoxicity, even carcinogenicity and teratogenicity. Furthermore, PGRs are suspected to disrupt the function of human and animal reproductive systems. This paper presents an overview on various toxicities of PGRs on human and animal reproductive health and their underlying mechanisms, aiming to arouse people's attention to PGR residues in food and environment and reduce PGR-induced damage to the male reproductive system and to human health as well.
