In vitro fertilization (IVF) is a life-changing journey for many hopeful parents, but it can also feel overwhelming—especially when it comes to understanding the numbers behind the process. One of the most common questions people ask is: “How many eggs will be retrieved during IVF?” The answer isn’t one-size-fits-all. It depends on several factors, with age being one of the most important.

In this article, we’ll explore the average number of eggs retrieved during IVF based on age, what influences these numbers, and how to interpret them. We’ll also provide practical tips to help you optimize your IVF experience. Whether you’re just starting to research IVF or are already in the process, this guide will give you the clarity and confidence you need.

What Is IVF and Why Does Egg Retrieval Matter?

Before diving into the numbers, let’s quickly review what IVF is and why egg retrieval is such a critical step.

In vitro fertilization (IVF) is a fertility treatment where eggs are retrieved from a woman’s ovaries and fertilized with sperm in a lab. The resulting embryos are then transferred back into the uterus, with the goal of achieving a successful pregnancy.

Egg retrieval is the process where doctors use a thin needle to collect eggs from the ovaries after a period of hormonal stimulation. The number of eggs retrieved plays a big role in the success of IVF because:

• • More eggs mean more chances for fertilization.

• • Not all eggs will fertilize or develop into healthy embryos.

• • Having multiple embryos increases the likelihood of a successful pregnancy.

However, it’s not just about quantity—egg quality is equally important. As we’ll see, both quantity and quality are influenced by age.

Average Number of Eggs Retrieved by Age: What the Data Shows

Age is one of the strongest predictors of how many eggs will be retrieved during IVF. Here’s a breakdown of the average number of eggs retrieved based on different age groups, according to recent studies and fertility clinic data.

Age 25-29

• • Average eggs retrieved: 12-15

• • Why: Women in this age group typically have a higher ovarian reserve (the number of eggs left in the ovaries). Their bodies respond well to stimulation, leading to a higher egg yield.

Age 30-34

• • Average eggs retrieved: 10-12

• • Why: Ovarian reserve starts to decline slightly, but most women in this age group still produce a good number of eggs.

Age 35-37

• • Average eggs retrieved: 8-10

• • Why: At this stage, the decline in egg quantity becomes more noticeable. However, many women can still retrieve a sufficient number of eggs for a successful IVF cycle.

Age 38-40

• • Average eggs retrieved: 6-8

• • Why: Egg quantity continues to decrease, and the response to stimulation may be lower. However, with the right protocol, many women can still achieve good results.

Age 41-42

• • Average eggs retrieved: 4-6

• • Why: Ovarian reserve is significantly lower, and the number of eggs retrieved drops. However, some women may still respond well, especially if they have a higher baseline ovarian reserve.

Age 43 and older

• • Average eggs retrieved: 2-4

• • Why: At this age, egg quantity is at its lowest, and the chances of retrieving multiple eggs decrease. However, IVF can still be successful, especially with personalized treatment plans.

Important Note: These are averages, not guarantees. Some women may retrieve more or fewer eggs depending on their individual health and fertility factors.

Factors That Influence the Number of Eggs Retrieved

While age is a key factor, it’s not the only one that affects how many eggs are retrieved during IVF. Here are other important factors to consider:

1. Ovarian Reserve

• • What it is: Ovarian reserve refers to the number of eggs left in your ovaries. It naturally declines with age but can vary widely between women of the same age.

• • How it’s measured: Doctors use tests like antral follicle count (AFC) and anti-Müllerian hormone (AMH) levels to estimate ovarian reserve.

• • Impact: Women with a higher ovarian reserve tend to produce more eggs during IVF, regardless of age.

2. Stimulation Protocol

• • What it is: The combination of medications used to stimulate the ovaries to produce multiple eggs.

• • How it affects egg retrieval: Different protocols can lead to different responses. Your doctor will choose a protocol based on your age, ovarian reserve, and previous IVF history (if any).

• • Tip: Personalized protocols are key. What works for one person may not work for another.

3. Lifestyle and Health

• • Weight: Being underweight or overweight can affect how your body responds to stimulation.

• • Smoking: Smoking can reduce egg quantity and quality.

• • Stress: High stress levels may impact your body’s response to treatment.

• • Tip: Maintaining a healthy lifestyle can help optimize your egg retrieval results.

4. Underlying Health Conditions

• • Polycystic Ovary Syndrome (PCOS): Women with PCOS often have a higher number of eggs but may face challenges with egg quality.

• • Endometriosis: This condition can affect egg quality and quantity.

• • Tip: If you have a known health condition, discuss it with your doctor to adjust your treatment plan accordingly.

How to Interpret Your Egg Retrieval Numbers

It’s natural to feel anxious about how many eggs you’ll retrieve, but it’s important to remember that quality matters just as much as quantity. Here’s how to think about your egg retrieval numbers:

What’s a “Good” Number of Eggs?

• • General guideline: Retrieving 10-15 eggs is often considered optimal for women under 35. For women over 35, 8-10 eggs may be sufficient.

• • Why: This range gives you a good chance of having at least one healthy embryo for transfer.

• • But remember: Even if you retrieve fewer eggs, success is still possible. Some women achieve pregnancy with just a few eggs, especially if those eggs are of high quality.

Attrition: Why Not All Eggs Lead to Embryos

During IVF, not every egg will result in a viable embryo. Here’s a typical breakdown:

• • Maturity: About 80% of retrieved eggs are mature and can be fertilized.

• • Fertilization: Of those, around 70-80% will fertilize successfully.

• • Embryo development: Only 30-50% of fertilized eggs will develop into blastocysts (the stage ready for transfer).

Example: If you retrieve 10 eggs:

• • 8 might be mature.

• • 6 might fertilize.

• • 2-3 might develop into blastocysts.

This is why retrieving more eggs increases your chances—but it’s not the only factor.

Egg Quality vs. Quantity

• • Egg quality refers to the genetic health of the egg. High-quality eggs are more likely to fertilize, develop into healthy embryos, and result in a successful pregnancy.

• • Why it matters: As women age, egg quality declines, even if the quantity is still relatively high.

• • Tip: Focus on both quantity and quality. Your doctor can help assess egg quality through tests like preimplantation genetic testing (PGT).

Tips for Optimizing Your Egg Retrieval

While you can’t control your age or ovarian reserve, there are steps you can take to maximize your chances of retrieving a good number of eggs.

1. Work with a Fertility Specialist

• • Why: A specialist can create a personalized treatment plan based on your unique situation.

• • Tip: Choose a clinic with a strong track record in IVF success rates. Research clinics in your area and ask about their approach to stimulation protocols.

2. Consider Lifestyle Changes

• • Diet: Eat a balanced diet rich in antioxidants, which may support egg health.

• • Exercise: Moderate exercise can help, but avoid overexercising, which may negatively impact fertility.

• • Supplements: Some supplements, like CoQ10, may improve egg quality, but always consult your doctor first.

3. Manage Stress

• • Why: High stress levels can affect your body’s response to treatment.

• • Tip: Try relaxation techniques like yoga, meditation, or acupuncture. Many fertility clinics offer support groups or counseling.

4. Ask About Protocol Adjustments

• • Mini-IVF: For women with low ovarian reserve, mini-IVF uses lower doses of medication to retrieve fewer but potentially higher-quality eggs.

• • Natural cycle IVF: This involves retrieving the one egg your body naturally produces each month, which may be an option for some women.

Common Questions and Concerns About Egg Retrieval

Here are some of the most frequently asked questions about egg retrieval in IVF:

1. Is there a “magic number” of eggs for IVF success?

• • Answer: While studies suggest that retrieving 10-15 eggs is optimal for women under 35, success is still possible with fewer eggs. Quality matters just as much as quantity.

2. What if I retrieve fewer eggs than expected?

• • Answer: Don’t lose hope. Even with fewer eggs, you can still achieve a successful pregnancy, especially if those eggs are healthy. Your doctor can adjust your protocol for future cycles if needed.

3. Can I retrieve too many eggs?

• • Answer: Yes, retrieving too many eggs (over 20) can lead to ovarian hyperstimulation syndrome (OHSS), a condition where the ovaries become swollen and painful. However, with careful monitoring, this risk can be minimized.

4. Does the number of eggs retrieved affect my chances of pregnancy?

• • Answer: Yes, but it’s not the only factor. The quality of the eggs and the resulting embryos is equally important. Some women achieve pregnancy with just a few eggs, while others may need more.

5. How can I improve my egg quality?

• • Answer: While you can’t change your age, you can support egg health through a balanced diet, moderate exercise, and stress management. Some supplements may help, but always consult your doctor.
