Slow freezing, vitrification and ultra-rapid freezing of human embryos: a systematic review and meta-analysis.
Embryo cryopreservation is an important aspect of assisted reproduction. Many methods have been described, but they have been poorly investigated in randomized trials, highlighting the need for a systematic review of the literature. Meticulous electronic/hand searches were performed to locate randomized trials (RCT) comparing embryo cryopreservation methods. Primary outcomes were clinical pregn...
متن کاملMice Embryos Cryopreservation: Vitrification or Ultra-Rapid Freezing?
Background: The importance of mice as animal model for research has promoted the surge of many strains with important characteristics which need to be preserved. Embryo cryopreservation appears as the most suitable technique. However, until now there is not an effective methodology for this specie. This study aimed to evaluate three methods for mice embryos cryopreservation. Materials, Methods ...
متن کاملCryopreservation of human embryos by vitrification or slow freezing: a systematic review and meta-analysis.
OBJECTIVE To examine the literature systematically in order to identify prospective comparative trials answering the following question: Is vitrification of human embryos associated with a higher postthawing survival rate as compared with slow freezing? DESIGN Systematic review and meta-analysis. SETTING University-based hospital. PATIENT(S) Not applicable. INTERVENTION(S) Vitrification...
متن کاملCryopreservation of rainbow trout sperm by deep-freezing.
Cryopreservation trials on rainbow trout (Salmo gairdneri) sperm were carried out using two basic extenders: Mounib's medium (M) and Ménézo's medium (Me) to which were added bovine serum albumin (BSA) and tellurite egg yolk (Institut Pasteur). After 10 p. 100 of DMSO was added to these different deep-freeze diluents (DD), they were mixed with the sperm and then deep-frozen into 100 microliter p...
متن کاملFreezing within 2 h from oocyte retrieval increases the efficiency of human oocyte cryopreservation when using a slow freezing/rapid thawing protocol with high sucrose concentration.
BACKGROUND A number of factors influence the success of oocyte cryopreservation and subsequent ICSI. The aim of the present study is to establish the ideal time, after oocyte retrieval, for human oocyte cryopreservation via slow freezing/rapid thawing protocol with 0.3 M sucrose concentration in cryoprotectant solution (SF/RT 0.3 M). METHODS Retrospective study with 75 patients on the clinica...
