How to improve the quality of egg after the age of 40

Egg quality is one of the most important factors for a successful pregnancy and is a concern for women over the age of 40 who are trying to conceive naturally or with the help of IVF.

Females give birth to about 1 to 20 lakh eggs, of which only 300-500 mature and are available for lifelong use.

With age, the quality of the egg deteriorates and so does the ability to conceive. Poor egg quality can cause serious health problems in children.

A woman’s chances of conceiving after 40 drops significantly and in the case of pregnancy the chances of miscarriage are much higher.

Egg quality is a major factor in the decline in pregnancy and the growth rate of pregnancy.

Egg Quality and Age

The best way to measure egg quality is usually the proportion of female eggs that are genetically normal.

As a woman gets older, the amount of genetically normal eggs she can produce decreases.

The ovaries are also less able to meet the demands of the eggs that are growing with age, so a 40+-year-old woman’s eggs are more likely to contain errors in their genetic makeup.

Methods to Improve Egg Quality After 40

Although nothing can be done to prevent regular egg loss as one gets older.

There are many fertile supplements that one can take and diet and lifestyle changes can be made to improve egg quality after 40 and to improve the chances of getting pregnant at the end.

Diet for Fertility 

A diet that is high in fat and low in carbohydrates plays a significant role to improve overall fertility and egg quality. 

Fat is important for the growth of each and every cell in the body, giving energy to the body, supporting the growth of cells, absorbing nutrients and producing hormones.

Eggs are made of fat just like anything else in the body, so fat provides energy and nutrition to the egg which is required for proper development.

Good sleep is directly related to egg quality and fertility. Our bodies repair cells, rebuild energy and release hormones necessary for reproduction and other processes while we sleep, allowing the body to support the development of high-quality and healthy eggs.

Avoid Smoking

Nicotine impairs the quality and quantity of eggs. In addition, smoking increases the loss of eggs in the ovaries and increases the number of abnormal eggs produced.

Avoid Consumption of Caffeine and Alcohol

While you are trying to conceive, limiting consumption of caffeine or completely quitting alcohol can help improve egg quality.

Management of Stress

Stress can become the cause of several imbalances and problems related to fertility and egg quality throughout the body. When we are under stress our body produces increased levels of cortisol and prolactin and they can lower the ovaries, thereby inhibiting egg production.

Yoga and Exercise

Exercises such as walking, stretching and yoga are helpful to reduce stress and increase the flow of blood to your genitals which balances the immune system.

In addition, obesity also becomes the cause of increased oxidative stress on cells.


Fertility supplements may be helpful in improving the quality of eggs in women over 40 years of age. 

Some supplements that have been shown to increase antioxidant levels, and support a healthy ovarian environment to improve egg quality include:

Fish Oil (Omega 3)

This is a practical way to hold on to the aging of ovaries and can also be helpful to protect fertility and promote high-quality egg production, especially for women over 40 years of age.

Co-Enzyme Q10 (Coq10)

The level of coenzyme q10 inside the body decreases with age. It is important for women over the age of 40 to take the Co q10 supplement when they are trying to conceive.

It is an antioxidant that protects and supports mitochondria. The number of healthy mitochondria and CoQ10 levels decreases with age in women. CoQ10 supplements may improve energy in egg cells. 

Vitamin A

Vitamin A plays an important role in ensuring egg quality and blastogenesis which is an essential part of fetal development.

Other vitamins and nutrients that help with egg quality after 40 are:

  • Vitamin E is a source of strong antioxidant effects and is helpful to reduce oxidative stress which is essential for high-quality egg development.
  • Zinc and some vitamins B play a vital role in the synthesis of DNA, which is ALSO important for the development of high-quality oocytes.
  • Proper folate levels help in promoting the quality of oocyte, maturation, fertilization and implantation.
  • DHEA supplements can alter the low levels of androgens in the ovaries, resulting in a decrease in ovarian storage and poor-quality eggs.


Generally, females above 40-41 years of age are immediately referred for donor eggs as their eggs are of poor quality. 

Studies have shown that in women with poor ovarian reserve or premature ovarian failure, it may be possible to extend the egg-laying period, produce better quality eggs, and improve IVF success rates. Otherwise, donor eggs are a good choice for women over 40 who want to get pregnant.
