Effects of three abnormal conditions of fallopian tube on outcomes of the in vitro fertilization and embryo transfer technique.

AIM:The aim of this study was to demonstrate whether salpingitis affects the outcomes of in vitro fertilization and embryo transfer (IVF-ET). METHODS:The retrospective study includes patients from 2013 to 2018 who received their first IVF-ET treatment during this period. On the basis of their tubal conditions, the patients were subgrouped as: hydrosalpinx (group A), salpingitis (group B), tubal occlusion (group C). It had a total of 726 cycles, of which 208 cycles were in group A, 201 cycles in group B and 317 cycles in group C. The outcomes of the IVF-ET treatment were compared amongst the three groups. RESULTS:Group C had the highest number of retrieved oocytes as compared to the groups A and B, and the rate of the high-quality embryos at day 3 (66-68 h after insemination) was higher in the groups C and A compared to the group B. The blastocyst formation rate was significantly higher in group C compared to that of the group B. Group C had higher rates of implantation, clinical pregnancy and live birth compared to both groups A and B, while the birth weight of newborns did not differ amongst the three groups. CONCLUSION:Salpingitis has adverse effects on the success rate of the IVF-ET treatment, exemplified by lower implantation, clinical pregnancy and live birth rates compared to tubal occlusion, it may be necessary to carry out appropriate management of salpingitis before IVF-ET treatment.
