IVF Success Rate by Age: What You Need to Know

In-vitro fertilization (IVF) has helped millions of couples worldwide achieve their dream of parenthood. However, the success rate of IVF largely depends on various factors, with age being one of the most crucial. If you’re considering IVF, understanding how age affects your chances can help you make informed decisions. In this blog, we will explore IVF success rates by age, the factors that influence outcomes, and what you can do to improve your chances.

How Does Age Affect IVF Success?

A woman’s age significantly impacts fertility because ovarian reserve (the number and quality of eggs) declines over time. Younger women typically have healthier eggs, which increases the likelihood of fertilization, implantation, and a successful pregnancy. As women age, the number of viable eggs decreases, leading to lower IVF success rates.

IVF Success Rate by Age: A Breakdown

Let’s look at the success rates of IVF by age, based on recent data:

  • Under 35 Years: Women under 35 have the highest IVF success rate, with about 50-55% of cycles resulting in a live birth per embryo transfer.

  • 35-37 Years: The success rate drops slightly to around 40-45% per cycle.

  • 38-40 Years: Women in this age group experience a success rate of 25-30%.

  • 41-42 Years: The success rate further declines to approximately 10-15%.

  • Over 42 Years: The chances of a successful IVF cycle drop to 5% or less, often leading many women to consider donor eggs.

Why Does IVF Success Decline With Age?

Several biological factors contribute to lower IVF success rates as women age:

  • Diminished Ovarian Reserve: Fewer eggs available for retrieval.

  • Poor Egg Quality: Higher risk of chromosomal abnormalities.

  • Reduced Uterine Receptivity: The uterus may become less responsive to implantation.

  • Higher Risk of Miscarriage: Increased likelihood of early pregnancy loss.

Can You Improve IVF Success Rates?

While age plays a major role, there are ways to enhance IVF success:

  1. Lifestyle Changes: Maintain a healthy diet, exercise regularly, and avoid smoking or excessive alcohol consumption.

  2. Fertility Supplements: Certain vitamins like CoQ10 and DHEA may support egg quality.

  3. Preimplantation Genetic Testing (PGT): Helps select the healthiest embryos for transfer.

  4. Egg or Embryo Freezing: Freezing eggs at a younger age can preserve fertility for future IVF cycles.

  5. Consider Donor Eggs: Women over 40 often see higher success rates with donor eggs.

When to Seek Help

If you’ve been trying to conceive without success for over a year (or six months if over 35), consult a fertility specialist. At New World Fertility, we offer personalized IVF treatments to maximize your chances of success.

2. Can IVF work after 40?

Yes, but success rates decline significantly. Many women over 40 opt for donor eggs to increase their chances.

3. How many IVF cycles does it take to get pregnant?

On average, 1-3 cycles are needed for a successful pregnancy, depending on age and other health factors.

4. Is IVF painful?
