Abstract: Objective：To evaluate the efficacy of the laparoscopy and hysteroscopy combined with assisted reproductive techniques on the treatment of oviduct obstructive infertility. Methods：146 patients with oviduct obstructive infertility treated with the laparoscopy combined with hysteroscopy from February 2008 to August 2010 were followed up for the pregnancy. There were 112 patients （112/146） without pregnancy after six months of operation. Fifty-four cases （54/112） did IVF-ET. The pregnancy rate was analyzed. Results：In 146 cases，46 cases were pregnant after the laparoscopy combined with hysteroscopy （40 cases palace pregnancy，6 cases ectopic pregnant）. Among them，34 cases were pregnant between 0 and 6 months after surgery （30 cases palace pregnancy， 4 cases ectopic pregnant），11 cases were pregnant between 7 and 12 months （9 cases palace pregnancy，2 cases ectopic pregnant），1 case was pregnant after 12 months. In 54 cases treated with IVF-ET，23 cases were pregnant after 7 months to 1 year （21 cases palace pregnancy，2 cases ectopic pregnant）. Conclusions：The laparoscopy combined with hysteroscopy have both diagnostic and therapeutic value. Within six months after surgery，the pregnancy rate was the highest. Those patients who were not pregnant after 6 months of operation or had severe oviduct obstruction should do IVF-ET as early as possible.
