Abstract/OtherAbstract:
The first successful attempt at deep freezing and thawing of the human oocyte is reported. A twin pregnancy was achieved after insemination and replacement in utero. The procedure involved reduction in size of the oocyte/cumulus-oophorus complex, the addition of the cryoprotectant dimethyl sulphoxide as a one-step procedure, slow cooling between -7 degrees C and -36 degrees C after ice nucleation, and rapid freezing to -196 degrees C before storage in liquid nitrogen. Thawing was achieved rapidly by warming in a 37 degrees C water-bath, followed by dilution of dimethyl sulphoxide as a single step. 80% of forty oocytes showed morphological survival after freezing and thawing. Thirty of these were inseminated; 83% retained their capacity to be fertilised, and 60% proceeded to cleavage division.
