Even if ovulation is normal, fertility drugs are used to produce more than a single egg because pregnancy rates are higher with more eggs. An average of 10 – 20 eggs are usually retrieved for IVF. However, not all of them are viable to use as on average only about two-thirds have the appropriate maturity.

For all women, the odds of having a baby on the first IVF attempt was 29.5 percent. That stayed pretty steady through their fourth attempt, but the chance of having a baby jumped up to 65 percent by the sixth attempt.

How many of my eggs will fertilize? On average most patients will have 70-85% of their mature eggs fertilize. Immature eggs cannot be injected (ICSI) and will not fertilize in standard IVF. If the eggs are poorer quality and/or the sperm used is very poor, the fertilization may be lower than for the average patient.

During egg retrieval, you will be given pain medication and sedated, so the procedure itself should not be painful at all. After the procedure, you may experience some mild cramping or feelings of pressure. Pain can usually be treated with an over-the-counter medication like ibuprofen.

The more eggs produced from each IVF cycle, the better the chances of a live birth, but only up to about 13 eggs; after that, over stimulation may result in lower-quality eggs that are less likely to become fertilized and result in healthy embryos.
