Pursuing IVF at 40 is a significant decision, and you deserve honest information about what it involves, what the numbers mean, and what you can do to improve your outcomes before you begin.
What the Statistics Say and What They Do Not
Live birth rates per IVF cycle using your own eggs fall to approximately 15 to 25 percent at age 40 and decline further with each year. These numbers are real, and they matter for planning. But they are population averages that include women who walked into their first retrieval with significant unaddressed lifestyle and metabolic factors. They also say nothing about you as an individual. Research on women undergoing IVF found that at ages 40 to 44, roughly 45 to 60 percent of eggs are still chromosomally normal, and the researchers themselves noted that aggressive hormonal stimulation may be contributing to the abnormality rate. I have worked with women who were told to expect poor outcomes, followed a targeted egg quality protocol for three months, and retrieved more eggs than expected, with high quality among them.
How to Improve Your IVF Outcomes
Begin egg quality preparation at least three months before your anticipated retrieval. The eggs you retrieve began maturing roughly 100 days earlier, so this window matters. The core protocol is CoQ10 in the ubiquinol form at 200 to 400 mg daily, 2 to 3 grams of EPA and DHA daily, vitamin D tested and optimized to 50 to 70 ng/mL, methylfolate, and anti-inflammatory nutrition. These are not adjuncts to IVF. They are the preparation that makes IVF work better.

Discuss protocol options with your clinic. Low stimulation or mini-IVF may be more appropriate than standard stimulation if your AMH is low, since high doses of medication can be wasteful when only a few follicles are available. Many women on mini-IVF retrieve fewer eggs but better embryos. Preimplantation genetic testing, PGT-A, is often recommended at 40 and above, but it is worth understanding both sides. It can help some women, but it can also mislabel viable embryos as abnormal, and the ASRM does not consider it standard of care for everyone. Ask how many embryos you have to test and whether the results would change your plan. And if you already have embryos labeled abnormal, do not discard them without a second opinion.
Questions to Ask Your Doctor
What is your clinic’s live birth rate for my specific age and diagnosis? What stimulation protocol will you use and why? Do you recommend PGT-A, and how would the results change my treatment? How do you approach low ovarian reserve? Will my uterus be checked before transfer? What can I do in the three months before retrieval to improve my outcomes? A doctor who welcomes these questions is a doctor worth working with.
