Freezing Your Eggs is Much Harder Than You Realize

We recognize how to successfully freeze , entrepot , and thaw human sperm . We ’re still on a learning curve with human eggs . Abby Rabinowitz’srecent feature at Nautilusexplores the all - too circumscribed statistic about how well the summons works and the data point on why more hefty women are choosing to try out it anyway .

From the article :

For decades , the technical barrier to freeze eggs was the trouble of thawing them . “ I had just hundred of women clamor after me for testicle freezing engineering science , ” said Michael Tucker , a pass embryologist at Shady Grove Fertility and Donor EggBank USA . He was describing the flood of phone call he encounter after the publication of a 1997 clause about the former egg - immobilise technology . At the time , embryologist were using the “ slow - freeze down method”—the one I ’d used — which he and the rest of his theater generally find undependable . The orchis , as the tumid human cell , is highly liquid ; as it block , it forms ice crystals , which crack upon thaw .

In the former nineties , scientists started developing the new vitrification process , in which the ball is dehydrated , treated with anti - freeze , and jiffy - frozen at a lower temperature , which prevents ice rink crystal from form and increases luck of a successful warming . Over the past 10 eld , vitrification has largely supplanted tardily - freezing . Using vitrification , Tucker was “ much more supremely confident to say , yes , we can provide consistently upright birthrate outcomes . ”

The technique is undoubtedly a blessing to women who want child but call for medical treatments that will lead to sterilisation . But I conceive healthy woman thinking about “ banking ” some orchis for by and by shouldread the whole thing . Because at least right now , I ’m not certain that the betting odds are deserving it .
