New study aims to boost IVF success by testing smarter sperm selection
NCT ID NCT07626359
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at two ways to prepare sperm for IVF in men with high sperm DNA damage. One method uses a second ejaculate collected shortly after the first, and the other uses a special device that picks the healthiest sperm without spinning them. The goal is to see which method leads to more pregnancies. About 830 couples will take part.
