Some of the comments on the front page egg freezing article are pretty non-compassionate. While I agree that this is a thorny topic, I don't like the judginess festering over there. There ARE legitimate reasons why women might want to save up and freeze their eggs. As someone in a PhD program, I am intensely aware of my biological clock and how it relates to my career prospects. I know women in my shoes who are strongly considering saving up to freeze their eggs because otherwise you basically hit 35 right when you're looking for tenure track jobs or trying to get tenure — or else you might be looking for or in a postdoc, which is only slightly better paid than grad student salaries.
