A comparison of the various effects, in rats, of intrauterine insertion of copper-64 or copper-67 wire with the effects of intraperitoneal injection of copper sulfate solutions has shown that copper ions, dissolved from the wire, are locally active contraceptively and, in part, systemically absorbed.
对大鼠子宫内插入铜 - 64或铜 - 67金属丝的各种效应与腹腔注射硫酸铜溶液的效应进行比较后发现，从金属丝中溶解出来的铜离子具有局部避孕活性，并且有一部分会被全身吸收。
