Oocyte, embryo and blastocyst cryopreservation in ART: systematic review and meta-analysis comparing slow-freezing versus vitrification to produce evidence for the development of global guidance
BACKGROUND Successful cryopreservation of oocytes and embryos is essential not only to maximize the safety and efficacy of ovarian stimulation cycles in an IVF treatment, but also to enable fertility preservation. Two cryopreservation methods are routinely used: slow-freezing or vitrification. Slow-freezing allows for freezing to occur at a sufficiently slow rate to permit adequate cellular deh...
متن کاملNanoliter droplet vitrification for oocyte cryopreservation.
AIM Oocyte cryopreservation remains largely experimental, with live birth rates of only 2-4% per thawed oocyte. In this study, we present a nanoliter droplet technology for oocyte vitrification. MATERIALS & METHODS An ejector-based droplet vitrification system was designed to continuously cryopreserve oocytes in nanoliter droplets. Oocyte survival rates, morphologies and parthenogenetic devel...
متن کاملProspective randomized comparison of human oocyte cryopreservation with slow-rate freezing or vitrification.
OBJECTIVE To compare cryopreservation of mature human oocytes with slow-rate freezing and vitrification and determine which is most efficient at establishing a pregnancy. DESIGN Prospective randomized. SETTING Academically affiliated, private fertility center. PATIENT(S) Consenting patients with concerns about embryo cryopreservation and more than nine mature oocytes at retrieval were ran...
متن کاملI-10: Vitrification of Baboon Ovarian Tissue:Will Vitrification Replace Conventional Freezing for Ovarian Tissue Cryopreservation?
Background: The aim of this study was to evaluate the efficacy of a vitrification protocol developed by our group to cryopreserve ovarian tissue. For this, we used ovaries from non-human primates in order to have an animal model close to the clinical setting. Materials and Methods: Ovarian biopsies from five adult baboons were vitrified, warmed and autografted. After five months, follicle survi...
متن کاملOocyte and embryo vitrification in the IVF laboratory: a comprehensive review.
Vitrification is an excellent tool in the IVF laboratory, enabling options and offering flexibility in assisted reproduction. The technology of cryopreservation has been underway since the early 20th century. The advent of vitrification has advanced the expectations in routine clinical practice in the IVF laboratory presenting impressive results both in post-thaw survival, and in clinical pregn...
