A Study of Lidocaine Pertubation as a Treatment for Unexplained Infertility

Couples interested in participating in the clinical study must have undergone a complete investigation for their infertility and have at least one year of unsuccessful attempts to achieve pregnancy. Following inclusion in the study, patients will be monitored with vaginal ultrasound to ensure a leading follicle of at least 18 mm.The subjects with one or two follicles ≥18 mm will be given Ovitrelle® (Merck), dose 250 ug (6500 IU) of Human Chorionic Gonadotropin (HCG), subcutaneously for ovulation induction. 12-24 h after the HCG injection, patients will be randomized and pertubated with either test or control solution. 12 -24 hours after the pertubation insemination (IUI) will be given to all patients. A blood sample is taken 14-17 days after IUI, for analysis of serum HCG level and possible pregnancy. In case of positive answer a second confirmatory sample will be obtained 48-72 hours later. In case of confirmed elevated HCG, the clinical pregnancy (CP) will be assessed with vaginal ultrasound examination 6-7 week after IUI. Baby take home rate data will be collected for couples with clinical pregnancy.
