No difference in the incidence of gonorrhoea was observed at a venereal disease clinic between women using a copper-coil intrauterine device (IUD) and women using oral contraceptives. Experiments in vitro demonstrated that copper sulphate has a deleterious effect on Neisseria gonorrhoeae, but the presence of serum protects the gonococci from the toxic effect of copper ions.
在一家性病诊所中,使用铜制宫内节育器(IUD)的女性和使用口服避孕药的女性之间,淋病发病率未观察到差异。体外实验表明,硫酸铜对淋病奈瑟菌有有害作用,但血清的存在可保护淋球菌免受铜离子的毒性作用。
