Effect of pre-vitrification embryo collapse on clinical outcomes after cryotransfer

Investigation subject: blastocysts collapse by applying a laser pulse improves embryo survival outcomes after vitrification and thawing and could also increase clinical outcomes.

Objective: to test whether laser-mediated blastocyst collapse has a beneficial effect on clinical outcomes in patients undergoing cryotransfer.

Current situation: study completed. Pending completion of clinical results up to live birth.

Location: multicentre project of all the Instituto Bernabeu clinics.

Coordinated by: Dr Jorge Ten and Alba Bellón (student at Master in Reproductive Medicine).
