Background: Infertility not only as a disease but also as a serious problem affects the family and harms its health.Approximately 50 to 80 million people in the world suffer from infertility. Laparoscopy is a golden standard which helps diagnose peritoneal and the fallopian tubal problems and treat them.Materials and Methods: In this cross-sectional study, 162 infertile women referring to the Honari Clinic of Jahrom, Iran from 2008 to 2010 were enrolled. Laparoscopy was applied for these women due to other unsuccessful treatments. Information was collected from medical documents and analyzed by SPSS 11.5.Results: With the mean age of 27.2±5.31years, 95.7% of the cases had their first marriage, 80.2% had primary infertility, and 93.8% were housewives. The result of hysterosalpingography revealed normal fallopian tubes in 126 cases (77.8%). Of all the cases 18.5% had had unsuccessful intra-uterine injection of sperm. According to the laparoscopic findings and evaluation of ovarian problems, the causes of infertility included 66% ovarian cysts, 4.3% adhesions, 9.9% endometrioses. Also, the evaluation of the fallopian tubes showed 77.8% open tubes and 22.2% closed ones. The rate of pregnancy after laparoscopic surgery was 54.9%, most of which (84.6%) had been after cauterization of polycystic ovaries.All of these pregnancies had been spontaneous, of which 83.15% had led to termination and 16.85% had ended in abortion. None of the cases had had ectopic pregnancy or any other problem.Conclusion: The most common cause of women's infertility in Jahrom is polycystic ovaries, which in most cases is fortunately treated after laparoscopy. Hence cauterization of ovaries by laparoscopy can be an effective treatment for infertility.
