The active oviductal transportation capacity was studied in 73 infertile women by the use of a new deposition technique of radioactive particles into the internal cervical os. The main reason for this study was that a previous observation had shown that such a transportation capacity was lacking in 41% of the infertile patients with a normal hysterosalpingogram. The examination was performed in the immediate preovulatory phase, i.e. on days -3 to 0 before the ovulation, as measured by the basal body temperature during two preceding cycles. The deposition of 99mTc-labelled albumin particles of 0.2-1.0 micron at the internal cervical os and the interpretation of the radionuclide images are described in detail. The results show that the bilateral active tubal transportation capacity was present in 42 patients. An impaired transportation capacity was diagnosed in 22 patients. In 9 patients, the particles never reached the uterine cavity, or all activity leaked back to the vagina.
采用一种将放射性粒子置于子宫颈内口的新沉积技术，对73名不孕女性的输卵管活动运输能力进行了研究。开展这项研究的主要原因是，先前的一项观察表明，在子宫输卵管造影正常的不孕患者中，有41%缺乏这种运输能力。检查在排卵前即刻进行，即根据前两个周期的基础体温测量，在排卵前-3至0天进行。详细描述了0.2 - 1.0微米的99mTc标记白蛋白颗粒在子宫颈内口的沉积及放射性核素图像的解读。结果显示，42例患者双侧输卵管具有活动运输能力。22例患者被诊断为运输能力受损。9例患者中，粒子从未进入子宫腔，或所有活性物质都回流到了阴道。
