Cryopreservation describes techniques that permit freezing and subsequent warming of
biological samples without loss of viability. The application of cryopreservation in assisted …

In contrast to the preimplantation mammalian embryo, it has been notoriously difficult to
cryopreserve the metaphase II oocyte. The ability to store oocytes successfully at− 196° C …

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 …

BACKGROUND Cryopreservation is now considered as an efficient way to store human
oocytes to preserve fertility. However, little is known about the effects of this technology on …

Extracellular vesicles (EVs) contain multiple factors that regulate cell and tissue function.
However, understanding of their influence on gametes, including communication with the …

BACKGROUND The aim of this study was to investigate the effect of sodium selenite (SS) on
reactive oxygen species (ROS) production, total antioxidant capacity (TAC) and glutathione …

Cryopreservation techniques for mammalian oocytes and embryos have rapidly progressed
during the past two decades, emphasizing their importance in various assisted reproductive …

Since the introduction of human assisted reproduction, oocyte cryopreservation has been
regarded as an attractive option to capitalize the reproductive potential of surplus oocytes …

OBJECTIVE: To investigate spindle behavior during and after slow freezing at room
temperature (RT) and vitrification at different temperatures. DESIGN: Randomized …

BACKGROUND: The aim of this work was to examine the effect of 1, 2-propanediol (PrOH)
and type of cryopreservation procedure (slow freezing and vitrification) on oocyte …
