作者复习了以往资料如下:已知铅会影响鱼、鸟、哺乳类和人类的生殖功能,铅不仅为堕胎药,而且对雄性生殖器官和生殖能力有毒性效应。在两组接触铅的工人中,其平均血铅为53μg/dl和74μg/dl,观察到精子无力、精子减少和精子畸形且生育力降低,但未见尿中促性腺激素改变。在职业性铅中毒患者中,见生殖功能降低与下丘脑垂体轴障碍有关。给实验动物以500或1000μg/ml醋酸铅,经60天,见睾丸受到影响。文献中尚末见低浓度暴露对睾丸有否影响的报道。为 The authors review previous literature as follows: Lead is known to affect the reproductive functions of fish, birds, mammals and humans. Lead is not only an abortion drug but also has a toxic effect on male reproductive organs and reproductive capacity. Among the two groups of workers exposed to lead, the average blood lead was 53 μg / dl and 74 μg / dl, sperm weakness, sperm loss and sperm deformity were observed and fertility was reduced but no change in urinary gonadotropin was observed. In patients with occupational lead poisoning, see Reduced reproductive function and hypothalamic pituitary axis disorders. To the experimental animals with 500 or 1000μg / ml lead acetate, after 60 days, see testicles affected. The literature does not yet see the impact of low concentrations of exposure on the testes reported. for
