Fertility Boss Podcast #10: What is Egg Freezing?


Today I'm reading from my ebook, Easy Breezy Egg Freezy: A Guide to Deciding if Egg Freezing is Right for You.

Specifically Chapter 2: What the heck is egg freezing?


History of Egg Freezing

Egg freezing is fancy term for cryopreservation, which is the cooling of cells and tissues to subzero temperatures in order to stop biological activity.  It allows for preservation.

Are you having flashbacks of Encino Man circle 1992?! 



We have long been freezing sperm and embryos successfully.

The first human birth from a frozen sperm was in 1953.  

And then in the 1970s techniques were developed to freeze sperm and eggs slowly, it was literally called the slow freeze.  This allowed minimal ice formation. You don’t want ice crystals interfering with oocyte development.


What the Oocyte?

What is an oocyte? It’s a cell in the ovary that can undergo division to form an egg. 

Improvements in slow freezing lead to the first human birth from a frozen embryo in 1984.  And in 1986 slow freezing helped a birth from an oocyte. 

Yet in 2000, another method was developed in addition to slow freeze for freezing reproductive cells. This method is called vitrification.



Vitrification is cryopreservation with sufficient protectants and faster cooling.  It basically eliminates any ice formation and freezes the cell into a glasslike structure. 

Initially success rates were low but today have dramatically improved. 

Once rates dramatically improved for successful live birth rates, vitrification eventually became the approved method for freezing.


ASRM no longer considers egg freezing experimental in 2013

In 2013 egg freezing started becoming a talked about buzzy kind of term in the media.  This is because the American Society for Reproductive Medicine (ASRM) took egg freezing off of the experimental list.  

ASRM indicates that although egg freezing is not for every woman, it is no longer considered only experimental. 

This is when you heard large, progressive companies like Apple, Facebook and Google, start to cover egg freezing in their employee insurance policies. 


Live Pregnancy Rate Estimator

Based on an analysis of over 2300 egg freezing cycles in the US and Europe, scientists asserted that a woman and her doctor can make a much better decision about egg freezing based on her data.

  • Women are most fertile in their 20s and early 30s
  • Every woman is born with the number of eggs for her lifetime
  • Since 2013 egg freezing is no longer considered experimental
  • Freezing sperm and embryos has been around for over 60+years
