Abstract

Two new studies on mice have found that proteins in the ovaries may be the reason why some oocytes, or cells that mature into eggs, can remain healthy for decades. While it is not yet clear if human ovarian proteins have the same longevity, researchers believe that if they do, it would be remarkable. The studies used heavy and light versions of carbon and nitrogen to determine the age of proteins in the ovaries, and found that some proteins had a half-life of more than 100 days, lasting for most of the rodents' lives. These findings could potentially lead to diagnostic tests for fertility and egg freezing options. [Extracted from the article]
