Background:
Hysterosalpingoscintigraphy (HSSG) has given insight into the dynamics of rapid sperm transport inside the female genital tract.
Results:
While there is an increase of an ipsilateral transport on the side bearing the dominant follicle in 70% of the subjects in the periovulatory phase, 15% of the patients do not demonstrate transport to the fallopian tubes (negative HSSG). In these patients the pregnancy rate achieved spontaneously or by intrauterine insemination is significantly reduced compared to the patients who showed an intact transport mechanism confirmed by positive HSSG. On the other hand, by means of assisted reproductive techniques (ART), pregnancy rates were higher in the group of patients showing negative HSSG (P < 0.0005).
Conclusions:
Our data clearly indicate that HSSG is a helpful method to evaluate the integrity of the utero-tubal transport mechanism. As pregnancy rates remain low in patients with negative HSSG, this result should be considered as an indication for IVF-treatment even in patients with patent fallopian tubes and normozoospermia of the partner.
