P-70: Ultrasound Guided Artificial Insemination:A Randomized Controlled Trial

Background: To ascertain whether using ultrasound guidance during intrauterine insemination (IUI) could increase pregnancy rates. Materials and Methods: The population under study consisted of 73 consecutive couples subjected to IUI in our Human Reproduction Unit, between September and December 2006, with a total of 231 IUI cycles performed. The patients were randomized using a computer-generated, random numeric table, in two groups: ultrasoundguided IUI group (n=33) and clinical IUI group (n = 40). Results: The pregnancy rate was 16.04% per cycle in ultrasound guided IUI and 16.80% in control group; no statistically significant differences were observed between the groups. There were no differences in pregnancy rate per woman, nor in first cycle pregnancy rate. The cumulative pregnancy rate was also similar in both populations. There were no differences in pregnancy rate according to the different cervico-uterine angles. Conclusion: Ultrasound-guided intrauterine insemination does not produce better results than blind insemination, since the pregnancy rate per cycle is similar.
