Hey, no worries at all. I couldn’t even name any, I just know my wife had tried this option years before we met. I’ll breakdown our journey with as much as I can remember about cost:
IUI (wife carried, was 36 at the time but great fertility) 1 round at approx £3k that worked first time and resulted in our eldest daughter
IUI (me for our second, was 32 at the time with average fertility for my age) X2 that failed, approx £5,000 (bought 2 strands of sperm first time so didn’t incur this cost again)
IVF (me, 33 at the time) approx £9,000. 7 embryos and our second daughter is from our first and only transfer with the other 6 on ice.
You are right though, a lot does rely on luck. Have you both had your fertility checked? If not I would 100% recommend that to know what your most likely chance of success would be and then be able to cost it. I think it’s also good to be in with a clinic who can then give you an estimation tailored to your own fertility. I think our full fertility tests cost about £450 each.
where are you based? If south I would 100% recommend our clinic.
All that being said - we do have friends who got pregnant first time with at home IUI from an online donor. He went around their house to provide a sample and luckily it all worked out, I would just be so nervous in this case. I believe they send him updates on their son now & again.
