Background Intracytoplasmic morphologically selected sperm injection (IMSI) is still proposed and employed in the clinical practice to improve the reproductive outcome in infertile couples scheduled for conventional intracytoplasmic sperm injection (cICSI). The aim of the current randomized controlled trial (RCT) was to test the hypothesis that IMSI gives a better live birth delivery rate than cICSI. Methods Infertile couples scheduled for their first cICSI cycle for male factor were allocated using a simple randomization procedure. All available biological and clinical data were recorded and analyzed in a triple-blind fashion. Results Our final analysis involved the first 121 patients (48 and 73 subjects for IMSI and cICSI arm, respectively) because the trial was stopped prematurely on the advice of the data safety and monitoring Committee because of concerns about IMSI efficacy at the first interim analysis. No significant difference between arms was detected in rates of clinical pregnancy per embryo transferred [11/34 (32.3 %) vs. 15/64 (23.4 %); odds ratio (OR) 1.56, 95 % (confidence interval) CI 0.62–3.93, P = 0.343] and of live birth delivery [9/48 (18.8 %) vs. 11/73 (15.1 %); OR 1.30, 95%CI 0.49–3.42, P = 0.594). Conclusion Current data did not support the routine use of IMSI in the clinical practice for improving cICSI results in unselected infertile couples with male factor. |
