锌对儿童少年身体生长的重要作用已为众所周知。近年来,锌与性成熟的关系日益受到重视。大量研究证明锌对性成熟及正常性功能是必不可少的。一、锌在性激素的分泌及性器官发育中的作用早在50年代末就已证明,锌是睾丸维持正常生理作用必需的阳离子。动物实验和人体观察均已证明,缺锌能导致性发育不良和性功能低下。给刚断乳的年幼雄性大鼠饲以缺锌饲料7周,大鼠睾丸和前列腺重量明显低于正常对照组,也明显低于对饲组。缺锌大鼠血清睾酮水平明显减低。缺锌对成熟的大鼠也有严重影响,给成年雄性大鼠饲以缺锌饲料15
The important role of zinc in the growth of children and adolescents is well known. In recent years, the relationship between zinc and sexual maturity has been paid more and more attention. Numerous studies have demonstrated that zinc is essential for sexual maturation and normal sexual function. First, the role of zinc in the secretion of sex hormones and sexual development as early as the late 50’s have proved that zinc is necessary to maintain normal physiological role of testis cations. Animal experiments and human observation have proved that zinc deficiency can cause sexual dysplasia and sexual dysfunction. Young weaned young male rats were fed zinc-deficient diet for 7 weeks. The testis and prostate weight of rats were significantly lower than those of the normal control group and significantly lower than that of the control group. Zinc-deficient rats serum testosterone levels were significantly reduced. Zinc deficiency also has a severe effect on mature rats, and adult male rats are fed a zinc-deficient diet15
