  • Frozen
  • Outcomes of four published randomized controlled trials demonstrated that fresh and frozen oocytes yield similar pregnancy rates in IVF cycles, supporting the use of these technologies in well-selected patients aged 35 years and younger ( 8-11 ). (acog.org)
  • Clinical outcome data for frozen cycles between January 2011 and August 2012 were stratified according to carrier and cell stage. (biomedcentral.com)
  • Refined vitrification methods for embryos produce outstanding survival rates and have helped to improve pregnancy rates by allowing clinics to optimize embryo-endometrial synchrony in frozen embryo transfer cycles and to facilitate preimplantation genetic testing. (ivi-rmainnovation.com)
  • blastocysts
  • Surplus embryos and blastocysts after fresh transfer were cryopreserved by vitrification method. (hkmj.org)
  • Oocyte vitrification does not increase the risk of embryonic aneuploidy or diminish the implantation potential of blastocysts created after intracytoplasmic sperm injection: a novel, paired randomized controlled trial using DNA fingerprinting. (healthtap.com)

  • system
  • Depending on whether there is direct contact with the liquid nitrogen (LN 2 ), vitrification is commonly categorised into two types: 'open' and 'closed' system. (springer.com)
  • open
  • While open vitrification reaches extreme high cooling rates due to direct contact with LN 2 , risks for potential cross-contamination and disease transmission mediated through LN 2 increase when considering long-term cryopreservation. (springer.com)
