Objective: Evaluation of diagnostic laparoscopy findings in 600 unexplained infertility cases. Materials and Methods: A total of 600 diagnostic laparoscopies performed between 1995 and 2008 were investigated. Laparoscopies were performed in the proliferative phase of the cycle. General anesthesia was performed in all cases. Results: Normal genital findings were determined in 47.50% of primary infertile cases and in 47% of secondary infertile cases. Pelvic adhesion was the most frequent finding encountered and it was seen at a rate of 20% in the primary infertility group and 18% in the secondary infertility group. Endometriosis was determined to have a rate of 15% in the primary infertility group and 11.5% in the secondary infertility group. Conclusion: Laparoscopy has an important place in the diagnosis and planning in the treatment of infertility. Planning the convenient treatment for patients will prevent both economic loss and time loss.
