I have a medical condition where I have no vas deferens. Sadly, IVF didn't work. I don't say that to ask for sympathy, but to say that my wife went through the same series of needles, etc, without the payoff at the end. (Additionally I had to have a surgery to remove sperm from the testes, which was painful to recover from as you might imagine.) Anyone who embarks on the financial and emotional cost of IVF needs to be fully aware of the possibility that it won't work.
Note that the CDC collects statistics on assisted reproductive technology success rates. Here is the 2019 report: https://www.cdc.gov/art/reports/2019/pdf/2019-Report-ART-Fer... . See especially Figure 3 on page 29 (Percentage of embryo transfers that resulted in live-birth delivery, by patient age and egg or embryo source). There is more data, including from individual clinics, at https://www.cdc.gov/art/artdata/index.html .
