The American Society of Reproductive Medicine has issued a report that supports the freezing of human ova as a valid procedure in the treatment of infertility.
According to the report, the rates of successful fertilization, implantation and clinical pregnancy involving frozen eggs are positive enough to declare the procedure safe. Additional findings indicate that vitrification, the preservation of eggs without the use of ice crystals, does not increase the incidence of birth or chromosomal defects.
Cryopreservation techniques like egg freezing have come under criticism for their use by women who do not exhibit infertility issues. In some cases, women may choose to store their eggs in a cryogenic bank as a form of insurance.
Should a woman decide to put her career ahead of childbearing, she could retrieve her vitrified eggs in the future and become clinically pregnant that way.
“The bottom line is there is no guarantee,” said Dr. Samantha Pfeifer of the University of Pennsylvania, who chaired the society’s guideline committee. “A lot of women interested in using this technology are in their late 30s, early 40s, and they may have the worst success of anybody.”
The American Society of Reproductive Medicine stated that it does not support this practice.
Human egg vitrification can bring hope to couples who deal with infertility issues, such as women suffering from cancer, men with insufficient sperm amounts, or even people who think that crystallization of ova at low temperatures runs counterpoint to fertility procedures.
