Mean serum zinc (1.14 micrograms/ml) and copper (2.35 micrograms/ml) in 24 women taking oral contraceptive agents were compared against mean serum zinc (1.25 micrograms/ml) and copper (1.98 micrograms/ml) of 20 women of the same age range who served as controls. Serum zinc was significantly lower while serum copper was significantly higher for women taking the oral contraceptive agents. There was no significant correlation between the serum zinc and copper levels either in the control group (r = 0.04) or in the group taking the contraceptives (r = 0.36).
将24名服用口服避孕药的女性的血清锌均值（1.14微克/毫升）和铜均值（2.35微克/毫升）与20名同年龄范围的女性（作为对照）的血清锌均值（1.25微克/毫升）和铜均值（1.98微克/毫升）进行了比较。服用口服避孕药的女性血清锌显著较低，而血清铜显著较高。对照组（r = 0.04）或服用避孕药组（r = 0.36）的血清锌和铜水平之间均无显著相关性。
