title: [Morphologic changes in the ovary upon exposure to low temperatures (-196 degrees C) using cryoprotection].
abstract: The biological action of deep freezing (-196 degrees C) on the ovary with the purpose of establishing the possibility of using low temperatures for long-term storage of this tissue was studied. The use of polyethylene oxide of molecular weight 400 at an optimal concentration (20%) for freezing at a rate of 1 degree per minute to -8 degrees C, then 10 degrees/min to --196 degrees C permits to retain the functional activity of the ovary and restoration of its function after transplantation.
