Changes in electrical impedance of the vaginal medium during the menstrual cycle were recorded in female Rhesus monkeys using electrical probe and were correlated with estradiol-17 beta and progesterone plasma concentrations. A gradual decrease in impedance was observed during the follicular phase, the lowest values being observed between days 12-17 of the cycle. Impedance increased again during the first third of the luteal phase until day 21. The reversal of the impedance gradient's sign was nearly concomitant with the appearance of a detectable plasma progesterone concentration. These results support the use of vaginal impedance measurements as a help for the diagnosis of the periovulatory time in the female Rhesus monkey.
利用电探针记录了雌性恒河猴月经周期中阴道介质电阻抗的变化，并将其与血浆中雌二醇 - 17β 和孕酮的浓度进行关联。在卵泡期观察到电阻抗逐渐降低，在周期的第 12 - 17 天观察到最低值。在黄体期的前三分之一时间里，电阻抗再次升高直至第 21 天。电阻抗梯度符号的反转几乎与可检测到的血浆孕酮浓度的出现同时发生。这些结果支持将阴道电阻抗测量用于辅助诊断雌性恒河猴的排卵期。
