Alikat is right... the viability of frozen eggs, once thawed, is very very slim...
i think it is still difficult to freeze just the egg, unfertilized. however, if it weren't, i would recommend every 20-25 year old woman take out a loan and do it.
Back in our 20s...late 80s early 90s...I don't even know if freezing your eggs was an option. I didn't hear about it until about 2004 or 2005 as any sort of option. In fact even then I didn't realize the ramification of old eggs.
I have to say I had no idea it would be so hard for me either. I thought as long as I was having a regular period (every 28 days) I would not have any problems getting pregnant. Which basically was the case but then I didn't know about the high risk of miscarriage when you're in your late 30s, early 40s. That is all new stuff I learned in the past couple of years.
They don't bother to explain to you why time is against you. I know you don't even realize that your eggs age and it is much harder to find a good egg later on. They just say your fertility declines. It does suck and it is a lot harder.
Hang in there!
