【Objective】 To investigate the relevance between the preoperatively history of infertility patients and laparoscopic diagnosis of pelvic lesions

and to provide the basis for clinical treatment of infertility. 【Methods】 From November 2008 to October 2009

379 patients who went to hospital for laparoscopic examinations because of infertility treatment in gynecology department of our hospital were enrolled in the research. The patients’ infertility period

infertility types

history of surgery

and hysterosalpingography results were collected according to the criteria. According to the inclusion criteria

361 cases were included in the study. The different clinical characteristic were classified and analyzed according to laparoscopic diagnosis

which included pelvic/oviduct infertility

pelvic endometriosis or both of them. 【Results】 The analysis of pelvic diagnosis by laparoscope of 361 cases showed that the constituent ratio of pelvic disease was different comparing among the groups of different infertility periods

and the difference was statistically significant (P <0.05). In the groups of infertility period ≥10 years

pelvic /oviduct infertility factor was highest (76.5%)

and pelvic endometriosis in this group was lowest (5.9%). Primary infertility was not statistical different comparing with secondary infertility in laparoscopic pelvic lesions diagnosis (P > 0.05). According to the grouping of different surgery history

the etiology constituent ratios of pelvic lesions did not show statistically significant (P > 0.05). The patients having history of pelvic surgeries have a trend of higher percentages of the pelvic/oviduct factor infertility. The analysis of the results of HSG showed that when comparing the partial patency group of right or left oviduct with the corresponding patency one

there was no statistical difference (Both P > 0.05) under the diagnosis of laparoscope which including the diagnosis of normal

tubal blockage and pelvic adhesion. But when comparing the partial patency group of right or left oviduct with the corresponding blockage one

it was statistically different (Both P <0.05) under the diagnosis of laparoscope. When the HSG diagnosis of bilateral tube was patent

the result of laparoscopic diagnosis was consistent with it by 100%. But when the HSG diagnosis of bilateral tube was blockage

the consistency was only 72.0%. 【Conclusions】 The past medical histories of infertile patients are very meaningful for judging their infertility reasons. Relatively cheap hysterosalpingography has a good prediction effect for finding pelvic/oviduct inflammatory infertility reason.
