PROBLEM: The aim of this research was to investigate the effects of the intrauterine perfusion of hCG before a frozen-thawed embryo transfer (FET) in women with different implantation failure numbers.
METHOD OF STUDY: This was a retrospective analysis of patients undergoing FET who received an intrauterine injection hCG 1000 IU before embryo transfer. The groups included women with their first implantation failure (A group, n = 26), second implantation failure (B group, n = 122), and three or more failures (C group, n = 77). Corresponding control groups (no infusion) were also included. The pregnancy rates were compared among these groups.
RESULTS: After intrauterine injection hCG, the biochemical pregnancy rates were 92.30%, 63.11%, 49.02%, and the clinical pregnancy rates were 76.92%, 54.91%, 48.05%, in the A, B, and C groups, respectively. The biochemical and clinical pregnancy rates were significantly higher in the A group than in the other groups (P < .05). The clinical pregnancy rates of the A and C groups were significantly higher than in the corresponding (no infusion) control groups (76.92% vs 56.81% and 48.05% vs 33.33%, P < .05).
CONCLUSION: Pregnancy rates decreased with the number of transplant failures. The intrauterine administration of hCG before FET significantly improved the pregnancy rates, especially after one and three or more implantation failures.
