Patient: Dr. Malpani, during IVF, I often hear about ovarian reserve and ovarian response. But how do I really know how well my ovaries performed during a cycle?
Dr. Malpani: That’s a very important question. You’re right—your ovarian reserve (the number of eggs you have left) and your ovarian response (how well your ovaries respond to stimulation) both play a big role in IVF success. But there’s another useful concept many patients don’t know about: ovarian efficiency or ovarian responsiveness.
What Is Ovarian Efficiency?
Patient: Ovarian efficiency? What does that mean?
Dr. Malpani: Simply put, it’s a way of measuring how “efficiently” your ovaries converted the medications you took (gonadotropins) into mature follicles and eggs. IVF involves giving your body high doses of these injections, and ovarian efficiency helps us understand whether you needed a lot of medicine to get a few eggs—or whether you responded strongly to smaller doses.
How Do We Measure It?
Patient: So, how is ovarian efficiency actually calculated?
Dr. Malpani: There are three simple ways:
Number of mature follicles ÷ total gonadotropin dose (based on your ultrasound scans).
Estradiol (E2) level ÷ total gonadotropin dose (from your blood tests).
The most precise: Number of eggs retrieved ÷ total gonadotropin dose.
These numbers give us a clear picture of how much stimulation was needed for your ovaries to produce eggs.
The potency of gonadotropins used for IVF
Your ovarian efficiency will also be affected by the quality of the gonadotropin injections used for superovulation. Using poor quality urinary gonadotropins of low potency will artificially reduce your ovarian efficiency ! Often, the best way to improve ovarian efficiency is to use high-quality recombinant gonadotropins for superovulation
Why Is This Useful?
Patient: And what does this information tell me?
Dr. Malpani: It gives us insight into your prognosis. For example, younger women usually have higher ovarian efficiency—they produce more eggs with less medication. Older women, or women with reduced ovarian reserve, often require more injections for fewer eggs. Tracking this helps us counsel you better for future cycles, and it also ensures you’re not being overtreated with unnecessarily high drug doses.
A Guide for the Future
Patient: So, if my ovarian efficiency is low, does that mean IVF won’t work for me?
Dr. Malpani: Not at all. It simply means we need to be realistic about expectations and costs. It may also help us adjust the protocol next time to maximize your chances. Think of ovarian efficiency as a report card for how your ovaries behaved in this cycle. It’s not just about numbers—it’s about learning how to optimize your treatment going forward.
Patient Empowerment Through Data
Patient: I like this idea—it gives me a measurable way to understand my treatment. But most doctors don’t share these calculations with patients.
Dr. Malpani: Sadly, that’s true. Many IVF clinics don’t take the time to explain these details. But you have every right to ask. The more you understand, the better equipped you’ll be to make decisions about your next steps. IVF is too important and too expensive to leave to blind trust—empowered patients do better.
