Open versus closed oocyte vitrification in an oocyte donation programme: a prospective randomized sibling oocyte study Vrije Universiteit Brussel
Clinical validation of a closed vitrification system in an oocyte-donation programme Universiteit Gent
Vitrification of human ovarian tissue Vrije Universiteit Brussel
BACKGROUND: Cryopreservation of ovarian tissue can be used to preserve the fertility of patients who are about to receive treatment(s) that could compromise their future ovarian function. Here we evaluate the effectiveness of a vitrification protocol by carrying out a systematic comparison with a conventional slow-freezing method on human ovarian tissue.
METHODS: Human ovarian samples (mean age 28.0 ± 1.1 years) were processed in ...
Influence of cell loss after vitrification or slow-freezing on further in vitro development and implantation of human Day 3 embryos Vrije Universiteit Brussel
Is the effect of cell loss on further cleavage and implantation different for vitrified than for slowly frozen Day 3 embryos?
SUMMARY ANSWER:
Vitrified embryos develop better overnight than slowly frozen embryos, regardless of the number of cells lost, but have similar implantation potential if further cleavage occurs overnight.
WHAT IS KNOWN ALREADY:
After slow-freezing, similar ...
Impact of embryo vitrification on children's health, including growth up to two years of age, in comparison with results following a fresh embryo transfer Vrije Universiteit Brussel
Objective: To assess health outcomes, including growth up to 2 years of age, in children born after embryo vitrification in comparison with children born after fresh embryo transfer. Design: A prospective cohort study. Setting: A single-center university hospital. Patient(s): Singletons born after the transfer of vitrified or fresh embryos, either at the cleavage or blastocyst stage between 2014 and 2018, were included. Intervention(s): ...
Vitrification negatively affects the Ca2+-releasing and activation potential of mouse oocytes, but vitrified oocytes are potentially useful for diagnostic purposes Universiteit Gent
Survival and post-warming in vitro competence of human oocytes after high security closed system vitrification. Vrije Universiteit Brussel
PURPOSE: To compare two vitrification methods and two warming methods for human oocyte vitrification using a high security closed device in terms of survival, fertilization and embryo development.
METHODS: For vitrification, oocytes were (1) immediately placed in equilibration solution or (2) they were gradually exposed to the cryoprotectants. For warming, oocytes were placed (1) in a 25 ?l preheated (37 °C) thawing ...
Outcome of closed blastocyst vitrification in relation to blastocyst quality: evaluation of 759 warming cycles in a single-embryo transfer policy Vrije Universiteit Brussel
METHODS Supernumerary blastocysts of IVF/ICSI patients with a fresh Day 5 transfer were vitrified using CBS-VIT High Security (HS) ...
