Planned oocyte cryopreservation for women seeking to preserve future reproductive potential: an Ethics Committee opinion

For women who want to try to protect against future in- fertility due to reproductive aging or other causes, planned oocyte cryopreservation (“planned OC”) is ethically permissible.

Volume 110, Issue 6, Pages 1022–1028


Ethics Committee of the American Society for Reproductive Medicine 


Planned oocyte cryopreservation (“planned OC”) is an emerging but ethically permissible procedure that may help women avoid future infertility. Because planned OC is new and evolving, it is essential that women who are considering using it be informed about the uncertainties regarding its efficacy and long-term effects.

Curious.  The article mentions that egg banking facilities are not required to report the outcomes of oocytes they've preserved to SART or the CDC.  Can anyone help me understand the definition of an "egg banking facility" and what they do?  Are there any other types of facilities that are helping women freeze their eggs that aren't required to report?

And why?

Hi Courtney,

The document states that "some facilities, such as those that provide only egg banking, are not required to report to SART or the Centers for Disease Control and Prevention (CDC) the outcomes of cycles using oocytes they cryopreserved. This lack of reported data also should be disclosed and explained to prospective patients."

The facilities mentioned are clinics that exclusively provide planned oocyte cryopreservation for women who wish to preserve their fertility. This is in contrast to clinics that offer planned OC as part of their services, but that also provide many other infertility services, such as insemination treatments, in-vitro fertilization (IVF), and third party reproduction services.

To make it more confusing, there are also "egg banks" which cryopreserve donor oocytes with the goal of rapidly providing them for prospective recipients of donor egg-derived embryos. The concept of egg banks allows multiple recipients to benefit from one "batch" of donor eggs (eggs derived from one stimulation cycle) and is described here:

Hope that helps a bit,
