Media temperature control: a potentially important quality control parameter in human oocyte vitrification [PDF]

open access: yesReproduction and Fertility
The purpose of this study was to evaluate the role of controlling media temperature during human oocyte vitrification. This retrospective study compared fertilisation rates, cleavage-stage embryo development, and blastulation between two separate periods

Pituitary extract supplementation enhances follicular survival and gonadotropin receptor expression in vitrified ovarian tissue of Aceh cattle, Indonesia [PDF]

open access: yesVeterinary World
Background and Aim: Vitrification is a promising cryopreservation technique for conserving the genetic resources of Aceh cattle; however, it may induce cryoinjury and follicular apoptosis.

Improving native human sperm freezing protection by using a modified vitrification method

open access: yesAsian Journal of Andrology, 2021
Slow freezing is the most commonly used technique for the cryopreservation of spermatozoa in clinical practice. However, it has been shown to have a negative impact on sperm function and structure.

Interfering Effects of In Vitro Fertilization and Vitrification on Expression of Gtl2 and Dlk1 in Mouse Blastocysts [PDF]

open access: yesInternational Journal of Fertility and Sterility, 2020
Background Embryo vitrification is a key instrument in assisted reproductive technologies (ARTs). However, there is increasing concern that vitrification adversely affects embryo development. This study intends to assess the effect of vitrification on

Effect of Different Vitrification Techniques on Viability and Apoptotic Index of Domestic Cat Testicular Tissue Cells

open access: yesAnimals, 2023
Vitrification is essential for successful tissue cryopreservation and biobanking in wild cats. This study aimed to compare different methods of vitrification (Ovarian Tissue Cryosystem—OTC, Straws—STW, and Solid Surface vitrification—SSV) for testicular ...

The effect of different vitrification protocols on cell survival in human ovarian tissue: a pilot study

open access: yesJournal of Ovarian Research, 2021
Background Vitrification has superseded the slow freezing method for cryopreservation of oocytes, embryos, and sperm, but there are as yet no standard protocols for its use in ovarian tissue cryopreservation (OTC). Published protocols diverge mainly with

Programmed Cooling and Vitrification Method Applied to the Germplasm Preservation of Eriobotrya Plants

open access: yesHortScience, 2023
Long-term cryopreservation of germplasm is of great importance to maintaining genetic resources. A cryopreservation technology system has not yet been established for Eriobotrya, an important fruit tree in the Rosaceae.

Vitrification Ability of Combined and Single Cryoprotective Agents

open access: yesPlants, 2021
Cryoprotective agents (CPA) are an important part of many current vitrification methods. The vitrification ability of CPAs influences the probability of the glass transition and water crystallization occurrence.

Effect of the Re-Vitrification of Embryos at Different Stages on Embryonic Developmental Potential

open access: yesFrontiers in Endocrinology, 2021
BackgroundUsing re-vitrified human embryos for frozen-warmed embryo transfer (FET) is a valuable option when there are no other cryopreserved embryos to use, however, except for the PGT cases, no published data are available for FET with human embryos ...
