"egg life"

What is "egg-based dieting"?

Activities aimed at improving the quality of eggs.​

What makes a good quality egg?

For pregnancy to occur, it's important that steps 1-3 proceed smoothly, and in all cases, the key is that the eggs are actively and healthily functioning.

1. Awakens from dormancy and matures (follicle) 2. Receives sperm and fertilization occurs (egg) 3. Divides rapidly (fertilized egg)1. Awakens from dormancy and matures (follicle) 2. Receives sperm and fertilization occurs (egg) 3. Divides rapidly (fertilized egg)

Things you should know! How pregnancy works

Egg-related column As we age
"egg quality" will decrease

A study comparing the pregnancy and live birth rates of embryo transfer using a woman's own eggs versus embryo transfer using eggs donated by younger women has confirmed that aging is a factor that lowers both pregnancy and live birth rates.
It has been found that the main cause of declining fertility is the "decrease in egg quality" due to aging.

Treatment outcomes of assisted reproductive technology using donor eggs and the patient's own eggs.

It degrades the quality of the eggs.
Beware of oxidative stress!

In addition to aging, oxidative stress caused by factors such as smoking, stress, and poor diet has been shown to weaken the function of mitochondria, which are the energy source for eggs, and thus reduce egg quality.

  • Oxidative stress can impair the ability of mitochondria to produce energy effectively.
  • Mitochondria are energy-producing organelles found in most cells of the human body. They are also present in eggs (follicles), eggs, and sperm.

"Antioxidant"

To avoid oxidative stress, in addition to improving your lifestyle, it's also important to incorporate foods and supplements containing antioxidants into your diet.

Antioxidants (such as PQQ) help mitochondria produce energy.

Among various antioxidants, PQQ (pyrroloquinoline quinone) in particular has strong antioxidant properties and has been reported to have beneficial effects on the bodies of men and women trying to conceive.

*PQQ (pyrroloquinoline quinone) is a vitamin-like substance found in breast milk, as well as in natto, tofu, matcha, bell peppers, and other foods.

What are mitochondria?

Mitochondria are present in most cells, including egg cells, sperm cells, and granulosa cells within follicles, and they produce energy.
