Is the new Rapid-i carrier an effective system for human embryo vitrification at both the blastocyst and cleavage stage?
The Rapid-i offers an excellent alternative to existing open vitrification devices for embryo cryopreservation at the 8-10 cell stage as well as the blastocyst stage. Use of this type of "closed" sealed system that prevents direct contact between the embryos and liquid nitrogen reduces the potential risk of sample cross-contamination or infection. These preliminary data and live birth outcomes have paved the way toward transitioning to a closed vitrification system in our own IVF program.
It has been demonstrated that higher benefits of ESI were achieved in patients with short duration of symptoms and high percent of canal compromise.
