Summary

This study tested whether triggering the sperm's acrosome reaction (a natural process that releases enzymes to help fertilize an egg) before doing ICSI (a type of IVF) could improve pregnancy outcomes. Researchers enrolled 111 couples undergoing their first ICSI cycle with at least 6 eggs. The goal was to see if this pre-treatment reduces early pregnancy loss and improves the chance of a healthy baby.
