Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to compare the live birth rate between intracytoplasmic sperm injection (ICSI) and artificial oocyte activation (AOA) vs intracytoplasmic sperm injection alone in patients with teratospermia. The hypothesis is the live birth rate following ICSI and AOA is significantly higher than that by ICSI alone in patients with teratospermia. This is a randomized controlled trial. Participants will be randomly assigned into one of the two groups:

ICSI+AOA group: a single sperm will be injected within 4 hours after the follicular aspiration. All injected oocytes will be incubated in the calcium ionophore A23187 activation solution (C9275-1MG, Sigma, USA) for 10 min, and cultured in the cleavage medium (Cleavage Medium , Cook, United States) under standard conditions.

ICSI alone group: a single sperm will be injected within 4 hours after the follicular aspiration.
