铜对人类生命和健康是重要的,在生理上起着重要作用,参与血及胶原的生成和功能。以前认为铜不足在人类罕见,但近年出现了一些有关婴儿和成人铜不足的报告。目前,发现较多亚临床铜缺乏症。动物实验追踪元素,发现铜和锌的不足与受孕有密切关系。母牛铜不足的最早征候是受孕率下降,补充铜可获得显著改善。在人类铜对生殖方面的作用尚未研究,而锌的缺乏主要影响男性受孕(Hidiroglou,1979)。Jameson(1960)推测锌
Copper is important to human life and health and plays an important physiological role in the formation and function of blood and collagen. It was previously thought that copper deficiency was rare in humans, but in recent years there have been some reports of insufficient copper for infants and adults. Currently, more subclinical copper deficiency is found. Animal experiments track the elements and found that the deficiencies of copper and zinc are closely related to conception. The earliest signs of lack of copper in cows are a decrease in conception rates and a significant improvement in copper supplementation. The role of human copper in reproduction has not been studied, and zinc deficiency mainly affects male fertility (Hidiroglou, 1979). Jameson (1960) speculated that zinc
