What's your timeline? Are you anticipating using them with a partner or going it alone? If it's the latter then IVF with donor sperm and freezing the resulting embryos is another option. Embryos tend to survive the freezing and defrosting better. But obviously you can't then use a future partner's sperm.
I see the HEFA website says 18% success rate per cycle for frozen eggs which is low but not massively different to the rate for frozen embryos or normal IVF for someone your age (23%) for both.
What is pretty certain is your egg quality will decline, hence the IVF success rates are lower than 18% in almost all cases for any age group older than your current one.
If you do leave it then another option further down the line would be to use a donor egg, so you could think about how you'd feel about that.
Is it worth it? Only you can answer that, that's why there are no 'solid statistics'! I'd start with asking can you afford enough cycles for a decent chance of success (i.e. enough egg collection cycles to gather sufficient eggs given the proportion that will survive - the clinic should give you an idea of how many - plus 5 or 6 implantation attempts given the 18% success rate), whilst knowing that it might not work. And if you want more than one child can you afford to double that amount?
If you can afford it, definitely want to have children, but don't want to have them yet then it may be the only way you can have them with your own eggs, if that matters to you, but you won't ever know for sure unless you wait several years and try conceiving naturally. And if you freeze them it's not an absolute insurance policy.
