Objective: To explore the impact of endometrial scratch injury (ESI) on intrauterine insemination (IUI) success. Methods: One
hundred and fifty four infertile women received 100 mg of oral clomiphene citrate for 5 days starting on day 3 of the menstrual
cycle. Patients were randomized to 2 equal groups: Group C received IUI without ESI and group S had ESI. Successful pregnancy
was confirmed by ultrasound. Results: 13, 21, and 10 women got pregnant after the first, second, and third IUI trials, respectively,
with 28.6% cumulative pregnancy rate (PR). The cumulative PR was significantly higher in group S (39%) compared to group C
(18.2%). The PR in group S was significantly higher compared to that in group C at the second and third trials. The PR was
significantly higher in group S at the second trial compared to that reported in the same group at the first trial but nonsignificantly
higher compared to that reported during the third trial, while in group C, the difference was nonsignificant. Eight pregnant women
had first trimester abortion with 18.2% total abortion rate with nonsignificant difference between studied groups. Conclusion:
The ESI significantly improves the outcome of IUI in women with unexplained infertility especially when conducted 1 month prior
to IUI. |
