So going through IVF but not implanting the embryo straight away? It’s about £4.5-5k for one round of IVF but that includes a transfer so not sure how much it would without the transfer.
Then medication costs vary on top of that, maybe £900. Then storage of your frozen embryos after that, maybe £300 a year.
I’d email a clinic, they’re really helpful with enquiries in my opinion.
Sperm donor costs you can see on the bank websites.
Access Fertility offer finance packages that can make things potentially cheaper.
