IVF Success Rate After 35: Factors Affecting IVF Success

Quick overview

This blog includes all the necessary information about IVF success rate after 35, including other factors that influence success such as age, egg quality, sperm health, etc. Also, it includes several ways to improve success chances and the right time to consider fertility treatment.

Introduction

Age is the most important factor while considering fertility. With age, the quality and quantity of eggs start to decline. Success rates are usually reported using measures such as pregnancy rates, live birth rates, clinical pregnancy rates, etc. 

Understanding all these factors can help the patient have realistic expectations and make informed decisions before taking fertility treatments. 

Why IVF Success Declines With Age

The main reason for the decline in the success of IVF is age, as the quality and quantity of eggs reduces after one reaches 30. As women get older, the ovaries generally contain fewer eggs. The proportion of eggs with chromosomal abnormality may increase. It can reduce the chances of producing a normal embryo and increase the risk of miscarriage.

IVF can help in fertilization, embryo development and embryo transfer but it cannot reverse age related changes if IVF fertility. 

IVF Success Rates By Age

The below table provides understanding on how egg influences the success rates with age:

 

Age	General IVF result
Under 35	Highest success rates with own eggs
35-37	Good chances, but success begins to decline
38-40	Generally, success decreases noticeably
41-42	Less chances of success with own eggs
43 and above	Very less success chances with own eggs

 

Actual results vary by clinic, treatment, diagnosis, embryo quality, ovarian reserve. The CDC also states that the published success rates by clinic does not indicate success for every patient as the success rates depend on various factors such as age, egg quality, sperm quality, etc.

IVF success rate at 35

IVF can have favourable results at the age of 35, when the ovarian reserve and reproductive health are good.

The CDC supported national analysis found a model cumulative live birth rate of 48% after the first egg retrieval of a patient aged 35, with a BMI of 25, no previous pregnancy and unexplained infertility. This increased with additional retrievals as the model considered embryo transfers occurring within 12 months. 

However, a person’s individual chances may be higher or lower due to medical conditions.

IVF Success Rate at 37-39

Between these age, declining egg quality and quantity could be more crucial. Some women could produce good quality embryos while others can’t. If fewer eggs are retrieved, there may be fewer embryos ready for selection and transfer.

Doctors could evaluate ovarian reserve using va

rious tests such as AMH, antral follicle count and other tests. This can help in stating how the ovarian reserve would respond, but it cannot justify that the IVF results in live birth.

IVF Success Rate after 40

IVF can still result in pregnancy after 40, but pregnancy after 40 with own eggs generally declines. But success may not result in a single IVF cycle, some may need more than one cycle to achieve success.

Factors That Affect IVF Success Rate After 35

There are several factors that affect IVF success rate after 35. Those are:

• Egg quality: Egg quality is one of the major factors in IVF success rate. With increasing age, the proportion of eggs with chromosomal abnormality sometimes increases, which may affect the embryo development and implantation.

• Ovarian reserve: Ovarian reserve means remaining supply of eggs. A lower ovarian reserve may result in a lower number of eggs being retrieved during IVF. A woman can have reasonable ovarian reserve, but can still experience a decline in egg quality.

• Sperm health: Women’s age is not the only factor for the success rate. Sometimes, the sperm quality also plays a major role in it. Sperm count, movement and morphology can also affect fertilization and embryo development.

• Lifestyle and overall health: Our day to day activities play a vital role in this. Maintaining a healthy diet, healthy weight, limiting alcohol, and avoiding smoking can affect overall reproductive health.

Can IVF Help In The Chances Of Pregnancy After 35

IVF can help with some fertility problems by helping doctors in egg collection, embryo selection and placing the resulting embryo in the uterus.

For some patients, embryos can be frozen and can be used later, so immediate egg collection may not be needed. 

However, IVF is different for every person. Factors such as age, sperm quality, egg quality, cause of infertility can affect the chances of success. Every clinic’s success rate does not guarantee the same result for every patient.

Does IVF With Donor Eggs Have The Highest Success Rate After 35?

Some patients are suggested IVF with donor eggs if their own egg quality and quantity have decreased. The age of the egg donor is more relevant in these cases for the success than the recipient’s age. 

The CDC reports donor’s egg and donated embryo success separately because the intended parent’s age does not affect success in the same way when donor eggs or donated embryos are used.

How To Improve IVF Chances After 35?

Several steps can help improve IVF success rate after 35. Those are:

• Consult a doctor rather than delaying the test
• Follow IVF medication regularly as prescribed
• Maintain a balanced diet and healthy lifestyle
• Avoid smoking and drugs
