The present study aims to explore the effectiveness of laparoscopic surgery on women presenting with infertility, of unidentified aetiology according to the standard infertility investigation, and recurrent failed In Vitro Fertilization (IVF) attempts. Identifying and correcting possible underlying pathologies by laparoscopy may subsequently enable natural conception in an effort to address infertility and avoid IVF overuse. One-hundred and seven (107) women with unidentified aetiology of infertility and recurrent failed IVF attempts met the inclusion criteria. Laparoscopic surgery was performed as the endpoint of the patients’ diagnostic journey, aiming to identify a possible underlying factor as the cause of infertility. Sixty-two (62) out of 107 patients (57.94%) that underwent laparoscopy were diagnosed with endometriosis, 25 out of the 107 patients (23.3%) were diagnosed with periadnixal and pelvic adhesions, and 20 cases (18.69%) presented with no pathology and remained unexplained. Following identification and correction of endometriosis and pelvic adhesions, patients were invited to conceive naturally. For the patients that laparoscopic investigation failed to reveal any pathology they were categorized as unexplained infertility and were subjected to a single IVF cycle. Natural conception success rate within the first postoperative year was the primary outcome. Within the first postoperative year, 30 out of 62 patients (48.38%) diagnosed with endometriosis following laparoscopic investigation achieved a natural conception, and 28 out of them (93.4%) reported live-births. Additionally, 11 out of 25 patients (44%) diagnosed with periadnixal and pelvic adhesions achieved natural conception within the first operative year. Regarding the group of unexplained infertility patients, only four out of the 20 patients (20%) achieved clinical pregnancy in the first post-operative IVF cycle. In conclusion, laparoscopy appears to be a promising approach, addressing infertility, providing significant diagnostic findings, while avoiding IVF overuse regarding patients of unidentified infertility presenting with recurrent failed IVF attempts.

This study tested whether embryo development yield using in vitro fertilization (IVF) could be improved by rocking cultures. Bovine ovaries were obtained at a slaughterhouse and transported to the laboratory within 6 h. Cumulus–oocyte complexes were collected and 20–25 were transferred in 100-μL drops of TCM-199 containing 10% fetal bovine serum and antibiotics under paraffin oil. Maturation was for 20–24 h at 38.5°C under 5% CO2 and 95% air in a humid atmosphere (IVM). In vitro fertilization was carried out for 6 h using frozen–thawed sperm from a single bull in modified Brackett and Oliphant (BO) medium. Presumptive zygotes were cultured in CR1aa supplemented with 10 mg mL–1 of BSA or 5% FBS for 9 d at 38.5°C under 5% CO2, 5% O2, and 90% N2 in a humid atmosphere (IVC). Rocking was performed to a height of 6 cm every 7 s using a Profile Rocker (New Brunswick Scientific Co., Edison, NJ, USA) in an incubator. Dishes were placed at a 15-cm distance from the fulcrum of the rocker. The conventional method (no rocking) served as a control, and every experiment was replicated 3 times. For Experiment 1, the effect of the period of rocking on developmental competence was examined when COC or zygotes were subjected to rocking for IVM, IVF, or IVC (IVM-move, IVF-move, and IVC-move). There were no significant differences in rates of oocyte maturation, cleavage, and development for IVM-move v. the control, or for rate of development between IVC-move and the control. However, the rate of fertilization for IVF-move was higher than that of the control (88.9 v. 67.5%; P < 0.01), and the rate of development was higher for IVF-move than for the control (39.0 v. 25.7%; P < 0.05). For Experiment 2, the effect of rocking frequency during IVF on development was determined. The IVF cultures were rocked every 7, 3.5, and 1.5 s (IVF-1move, IVF-2move, IVF-3move). The rates of cleavage on IVF-1move, IVF-2move, IVF-3move, and the control were 74.3, 69.8, 68.8, and 60.4%, and the rates of development were 39.0, 48.3, 26.2, and 25.7%, respectively. The rates of development on IVF-1move and IVF-2move were significantly different from the control and IVF-3move (P < 0.01). These results showed that rocking during IVF improved fertilization and embryo yield, and that frequency of rocking affected embryo development.
