Oocyte freezing no longer considered experimental


A new report from the Practice Committee of the American Society for Reproductive Medicine (ASRM) declares the practice of egg freezing no longer experimental. ASRM recognizes that egg freezing techniques for young women have produced pregnancies resulting in the birth of healthy babies, similar to IVF cycles which use fresh eggs. This report replaces the 2008 report which called the freezing of eggs experimental.

Maternal age is key to success

After reviewing almost 1000 reports, The Committee found enough proof to “demonstrate acceptable success rates in young highly selected populations.” However, they repeatedly underscored the age of the female at the time of egg freezing is an important factor. “Success rates with oocyte cryopreservation appear to decline with maternal age consistent with the clinical experience with fresh oocytes.”

A practical alternative

The report declares that egg freezing may be a practical alternative source of tissues for a family needing donor eggs. It is also a good strategy for fertility preservation for individuals who are left infertile after being treated for other diseases, genetic conditions, or IVF treatment obstructed by the inability to obtain sperm.

Cautioned against deferring childbearing

The Committee did not endorse general use of egg freezing for elective use. The claim there is not enough evidence on safety, cost-effectiveness, efficacy and the possible emotional issues. “Marketing this technology for the purpose of deferring childbearing may give women false hope and encourage women to delay childbearing. Patients who wish to pursue this technology should be carefully counseled.”
