NCT ID NCT06561451
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two IVF methods for couples where the male partner has severe sperm shape issues (teratospermia). One group gets standard ICSI (sperm injected into egg), the other gets ICSI plus a chemical boost to activate the egg. The goal is to see which leads to more live births. About 208 couples will take part.
