[Disturbed utero-tubal transport in hysterosalpingoscintigraphy as a predictive functional test for IVF therapy].
Hysterosalpingoscintigraphy (HSSG) is a simple method to evaluate the transport function of uterus and fallopian tubes. There is a quick uptake of radionuclides into the uterus and a transport to the side bearing the dominant follicle in 70 % of the patients in the late follicular phase of the cycle. Uptake and transport of the immotile radionuclides imitate the directed sperm transport through the female genital tract at the time of ovulation. 214 of 796 infertility patients with proven patency of fallopian tubes (27 %) showed only an uptake of the particles without a transport towards the fallopian tubes (negative HSSG). In these patients no spontaneous pregnancy occurred and pregnancy rate remained low by the means of timed intercourse or insemination. Indeed, the pregnancy rate (8.4 %) was significantly lower compared with the patients who became pregnant by timed intercourse, insemination or spontaneously and had a positive HSSG before (15 %; p=0.001). However, the pregnancy rate that could only be achieved by methods of ART was significantly higher in the group of patients with negative HSSG (57 % vs. 25 %, p=0.05). Our data suggest that HSSG is a new method to evaluate the integrity of the inner genital tract's transport function, especially in patients suffering from idiopathic infertility. Impaired transport function (negative HSSG) should be considered as an indication for IVF-treatment.
