RESUMO
Objective To evaluate the effect of different grades of pelvic inflammatory disease (PID)and of salpingectomy on outcomes of in vitro fertilization-embryo transfer(IVF-ET).Methods Two hundred and twenty three cycles of IVF-ET were divided into three groups,including mild group,moderate group and severe group,according to different grades of sequelae of PID finding in exploratory operations before IVF.Patients in each group were divided into two subgroups according to receiving salpingectomy or not.The data of total dose of gonadotrophin(Gn),oocyte number,low response rate,fertilization rate,good embryo number and pregnancy rate were analysed between three groups and the two subgroups of each group, respectively.Results All parameters were related to PID grades except fertilization rate.The total dose of Gn,oocyte number,good embryo number,low response rate and pregnancy rate were(2057?503)IU/L, (16?6),(6.0?4.3),4.2%,63.9% in mild group;(2204?603)IU/L,(12?6),(4.5?3.5), 13.9%,46.8% in moderate group;and(2372?1018)IU/L,(9?6),(3.1?2.9),33.8%,41.2% in severe group.The total dose of Gn and low response rate increased with the aggravation of the grades of PID (P
