is IVF worth it

So I recently changed my insurance and instead of covering 90% of infertility treatments it covers 0%. My options have run low because now it will cost me between $3-15k for any treatment. My doctor told me in this case IVF would be my best option. It's the most expensive but gives me 47% of a chance of becoming pregnant. Is this worth $10-15k? What if it doesn't happen the first time? Then I'm out that money and can't pay it again.
