最近,一种定时使用能够明确显示受检妇女有无生育力和能否怀孕的简单手持仪器研制成功。目前,检测妇女的生育能力和怀孕情况的手段,有二种:一种是监测血中雌激素水平变化的试验。虽然效果较好,但价格昂贵且费时较多;另一种是对宫颈粘液变化的光学检验,其可靠性较差。最近,耶路撒冷海达萨医学院罗果夫研究室的研究人员,根据阴道导电性的波动变化,创立了一种可由妇女自行操作的有效的监测方法。该研究室的生殖生理学家丁·伟因曼解释说: Recently, a time-tested, simple hand-held instrument that clearly demonstrated the fertility and pregnancy of test subjects was developed. At present, there are two kinds of measures to test women’s fertility and pregnancy: one is to test the change of blood estrogen level. Although the effect is better, but more expensive and time-consuming; the other is the optical test of cervical mucus changes, its reliability is poor. Recently, researchers at the Rogoff Laboratory at the Hadesa Medical School in Jerusalem, based on the vaginal changes in vaginal conductivity, have created an effective monitoring method that women can operate on their own. Ding Weinman, a reproductive physiologist at the lab, explained:
