Hamster oocyte penetration tests with oocytes frozen in propanediol: Comparison with non‐frozen oocytes

Gamete Research, 1989
AbstractHamster oocytes were frozen using a 1,2‐propanediol‐sucrose procedure, which resulted in over 90% survival. After thawing and zona removal the oocytes were compared with non‐frozen oocytes in a zona‐free hamster egg test employing spermatozoa from human semen donors and suspected infertility patients. Similar data were obtained, indicating that

Cryoconservation: Sperms and Oocytes

1997
From the moment of fertilization onwards, life processes run by the rhythm of a biological clock. The technology of cryopreservation gives us the possibility of interfering with the clockwork by stopping biological time. Cryopreservation of a cell therefore involves the cooling of a cell and storage at a temperature where all metabolic processes are ...

Genetics of oocyte ageing

Maturitas, 1998
Correlations between parental age, aneuploidy in germ cells and recent findings on aetiological factors in mammalian trisomy formation are reviewed.Data from observations in human oocytes, molecular studies on the origin of extra chromosomes in trisomies, experiments in a mouse model system, and transgenic approaches are shown.Errors in chromosome ...
