已知铜可以改变生殖系统的功能,动物实验中将缓慢释放铜的装置植入附睾、输精管、贮精囊或阴囊中,动物生育力下降,而取出此装置后生育力恢复。研究表明培养基质中加入的金属对精子是有毒的,精浆中铜浓度增加可引起不育。本文作者研究了有生育力和无生育力男子精浆中的铜浓度。 Copper is known to alter the function of the reproductive system. In animal experiments, devices that slowly release copper are implanted in the epididymis, vas deferens, seminal vesicle or scrotum, and the fertility of the animal is reduced. After removal of the device, fertility is restored. Studies have shown that the addition of metal to the culture medium is toxic to sperm, and increasing concentrations of copper in the seminal plasma can cause infertility. The authors studied the copper concentrations in fertilized and fertile men’s seminal plasma.
