Summary
: This prospective randomized observational study aimed to compare behavior of artificially collapsed blastocysts to blastocysts that were vitrified without artificial collapse.
Detailed description
One arm study of 60 patients with sibling blastocysts divided into 2 groups: Study group (artificially laser-collapsed blastocysts; n=71) \& control group (blastocysts were vitrified without laser collapse; n=66) then reexpansion speed and survival rate was assessed immediately \& at 140 min after thawing and compared between two groups.
