First seen Jan 24, 2026 · Last updated May 15, 2026 · Updated 21 times

Summary

This study tested a new way to choose sperm for in vitro fertilization (IVF). Instead of an embryologist picking sperm by hand, they used sperm that naturally attached to the egg's outer layer (zona pellucida). The goal was to see if this method leads to better embryo development. The study included 29 couples undergoing their first IVF cycle.
