I haven't read the full thread but I've read op's entries.
I'm quite surprised to read this question.
Putting aside the gift of a flat etc, which isn't really relevant, but if you are in your 20s, for most women eggs wouldn't have declined so much as to benefit from using frozen eggs. Cancer would be an exception to this, but women are often encouraged to freeze eggs before undergoing cancer therapies.
The success rate of defrosting and implanting frozen eggs successfully is pretty small.
I did read that Google offers egg freezing as an employment perk, but the problem is, a woman can feel she has more time, delay conceiving naturally completely, then when relying on the frozen eggs, does not meet with success.
Moreover the cost of the subsequent ivf can be enormous, so there are women with "banked" eggs who can't afford to use them.
Ultimately, it's a question between you and your own parents. Did you ask them, and if so, what did they say?
What have the doctors said is your fertility issue? Is it definitely something that would be solved by you having banked your eggs?
I'm sorry you're having trouble ttc. I expect you've tried doing a sperm count, and being really careful on dates and other tips like that? If you're at the ivf stage then I suspect you have tried all of that.
Best of luck with it I hope you get your baby!
