IVF After 40: What Your Success Odds Really Look Like
Considering in vitro fertilization after age 40? Learn about how age affects fertility, IVF success rates by age groups, factors that influence outcomes, and other fertility options that may help you build your family.

Age is one of the most important factors affecting female fertility. As women get older, both the number and quality of their eggs decline, making it more difficult to conceive naturally. 

That doesn’t mean pregnancy is out of reach. Many women over 40 successfully grow their families through in vitro fertilization (IVF). However, IVF success rates also decline with age. Understanding your chances of success and the factors that influence outcomes can help you make informed decisions about your fertility journey.

At CARE Fertility in Bedford and Fort Worth, Texas, our reproductive specialists help patients understand their options and work with you to develop a personalized treatment plan. Here’s what you should know about IVF after 40.

Why fertility drops after 40

You enter the world with your lifetime’s supply of eggs. Over time, both the quantity and quality of those eggs naturally decrease. As a result, it becomes more difficult to conceive and maintain a healthy pregnancy in your later reproductive years. 

In addition to changes in egg quality, age-related reproductive conditions can affect fertility. Conditions such as fibroids, endometriosis, and other gynecological issues may interfere with implantation or make pregnancy more challenging. 

IVF success rates by age

Advances in fertility treatment have improved IVF outcomes. However, age remains one of the strongest predictors of success.

Average IVF live birth success rates using a women’s own eggs are approximately:

  • Age 40-41: 13%
  • Age 42-43: 6%
  • Age 44 and older: 2%

These figures represent average live birth rates and may not reflect your individual situation. 

Factors that may improve chances of success

Although age plays a significant role, it isn’t the only factor that influences IVF success. Several other factors can affect your likelihood of becoming pregnant through in vitro fertilization. 

Ovarian reserve and fertility testing

A comprehensive fertility evaluation that includes diagnostic testing can provide valuable insight into your reproductive potential. An ovarian reserve test estimates the number of eggs you have and can help predict how you might respond to fertility treatment.

Lifestyle habits

A healthy lifestyle can’t increase your egg supply, but it may support reproductive health and egg quality. Eating a balanced diet, exercising regularly, and managing stress contribute to your overall wellness and fertility.

Overall health

Your overall health can also influence fertility and pregnancy outcomes. Chronic conditions such as diabetes, thyroid disorders, and high blood pressure are more common with age and may affect reproductive health. Proper management of these conditions can help support a healthy pregnancy.

Having an experienced fertility team that can guide you through your options and help you make informed decisions every step of the way is also an important factor. 

When to consider other fertility options

Many women experience greater success after multiple cycles of IVF. However, depending on your age, ovarian reserve, and treatment response, alternative family building options may offer a higher chance of success. 

We may suggest donor eggs if you have low ovarian reserve or poor egg quality. Because donor eggs usually come from younger women, success rates are higher than IVF using older eggs.

Gestational surrogacy is also an option when medical conditions affecting the uterus or pregnancy make carrying a pregnancy difficult or unsafe.

Every fertility journey is unique. Whether you’re considering IVF, exploring donor egg treatment, or simply looking for answers, our team is here to help.
