There are about 2 million eggs when you are born. However, by puberty, the number of eggs is reduced to 200,000 to 300,000. The number drops at a rate of 500 to 800 each time you ovulate – 100,000 by age 25, 50,000 by around age 35, and then thousands by your 40s. By the time of menopause, it is almost zero. The number of eggs is not infinite; it is finite. 

Supplements and exercise won’t prevent the aging of eggs

Not only are eggs limited in number, but they also age with age. Aging eggs become harder to fertilize and harder to get pregnant.

Some people take supplements and exercise as part of their infertility treatment. It’s true that smoking, unbalanced eating habits, and lack of sleep can make your eggs more prone to aging. Therefore, it is important to take supplements and exercise, quit smoking, and eat a well-balanced diet to help you get pregnant.

However, the fact is that eggs are controlled by the mitochondria, and supplements and exercise cannot prevent the aging of the eggs. Also, if you want to determine the aging status of your own eggs when you get pregnant, you will need to go to the hospital for an examination.

So, it’s good to take supplements, etc., however, it doesn’t mean that you can prevent the aging of the eggs.

With the passage of time, women’s lifestyles have changed, and more and more women are becoming active in society. While they play a role in society, they are getting married later, and as they do, they are getting older and thinking about getting pregnant. When they want to get pregnant, they may be in a situation where the number of eggs is significantly reduced and aging.

87% of people find it difficult to balance pregnancy and work!

According to a 2017 survey by the Ministry of Health, Labour and Welfare in Japan, as many as 87% of women who work while trying infertility treatment find it difficult to balance pregnancy and work.

As the number of eggs decreases and the aging process progresses, it becomes more difficult to get pregnant, and the time, cost, and physical burden of trying infertility treatment becomes greater. When that happens, you’re stuck in a vicious circle where it becomes increasingly difficult to balance work and life.

Therefore, it can be said that it is best to start infertility treatment as soon as possible while the number of eggs is high and the aging process is not progressing.


If you want to get pregnant, it’s better to try infertility treatment as soon as possible because there is a limit on eggs. It doesn’t mean that you can’t get pregnant as you get old. However, the possibility will be less. So, consider your lifestyle and having a life plan.
