I think the GP mentioned that because this subthread discussed a "permanent" solution for men. Storing sperm might be a workaround for future "wouldn't it be nice.." regrets. An insurance.
I'm not aware of mainstream (or any, really) permanent solutions for women, at least not to replace contraceptives (medical reasons - like cancer - for an invasive surgery don't count).
So, if women usually don't decide to become sterile (?), the process to collect and store eggs seems less relevant.
