The American Society of Reproductive Medicine (ASRM) and the European Society of Human Reproduction and Embryology (ESHRE) have endorsed oocyte freezing as a standard and safe procedure in 2012. ASRM issued a new report on 22 October, 2012 stating that in young patients egg freezing techniques have been shown to produce pregnancy rates, leading to the birth of healthy babies, comparable to IVF cycles using fresh eggs. After much work and deliberation by fertility experts, who reviewed the world literature on the effectiveness and safety of egg freezing and, most importantly, on the desired outcome: healthy babies, egg freezing is can now be used in routine practice. More studies are being published regarding this age range, and all is reassuring.
Egg freezing could provide a viable alternative source for couples needing donor eggs to build their families. In addition, among the medical indications for its use are fertility preservation for patients who may be left infertile following medical treatments for other diseases (viz., cancer), some genetic conditions, or IVF treatment interrupted by the unexpected inability to obtain sperm.
REASON FOR CAUTION:
The Committee points out that the age of the woman at the time of egg freezing is a very important factor. “Success rates with oocyte cryopreservation appear to decline with maternal age consistent with the clinical experience with fresh oocytes.” ASRM did not encourage egg freezing for “social reasons,” such as a delay in childbearing as, although the technical procedure of egg freezing is safe, we do not have enough long-term data about babies born to women using eggs frozen when they are older than 35. Citing a lack of data on safety, efficacy, cost-effectiveness, and potential emotional risks, the report states, “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.”
ROTUNDA EGG FREEZING PROGRAM:
Rotunda is now offering oocyte cryopreservation as part of its ART services using the latest cutting edge Cryotec vitrification technique. We also have initiated donor egg bank. We have achieved comparable success rates with frozen donor oocytes to fresh donor oocytes.
The excellent survival rates, embryo development and pregnancy rates have given a tremendous new hope to young cancer women. These young cancer patients can now dream of becoming a mother one day in future when they are cured of their disease.
