NEW EGG-FREEZING TECHNIQUE OFFERS HOPE TO INFERTILE CANCER VICTIMSMay 31, 2005 | www.Newsinferno.com
Chemotherapy and radiotherapy may save a female cancer patientâ€™s life but these therapies may also cause infertility. While freezing a womanâ€™s eggs before cancer therapy begins offers one possible option, the thawing process often renders the eggs incapable of being fertilized. Now, a team of researchers from the University of Michigan Comprehensive Cancer Center has studied a freezing technique called vitrification which freezes an egg instantaneously thereby preventing the formation of damaging ice crystals which destroy about 50% of frozen eggs. In trials using mouse eggs, vitrification has achieved a 98% egg survival rate.
