What is the approximate success rate of IVF per egg retrieval?

• A. About 5%
• B. About 20%
• C. About 35%
• D. About 50%

Answer: (B)

The main idea is that the chance of having a live birth from an IVF cycle that starts with retrieving eggs is about one in five on average. This per-retrieval success rate captures the realities that not every retrieved egg fertilizes, not every embryo results in a transfer, and not every transfer implants successfully. Age plays a big role: younger patients tend to have higher success rates, while older patients have lower ones, but when you look at a broad, generalPopulation, the approximate figure centers around 20%.

So, the best answer reflects the typical overall average: roughly 20% per egg retrieval. The other options are either too low or too high for the average cross-age estimate, though they might apply to specific subgroups or different definitions (like per transfer or per embryo).
