Why tired eggs don’t give babies

Every move you make, every thought which crosses your mind, virtually nothing in terms of you being alive happens without CoQ10 (abbreviated form for Coenzyme Q10).

CoQ10 is an essential part of an energy generating system that fuels each and every movement of your body. Interesting thing about CoQ10 is that its levels decline as we age, just like DHEA.


How CoQ10 determins egg quality?

First, imagine your eggs as little plastic bags full of water. In healthy eggs, there is plenty of stuff swimming around in this water and some of it resembles hundreds of rice corns scattered all over soup. Those rice corns are the mitochondria. For simplicity reasons, if you imagine your ovulating egg as your favorite handbag – mitochondria would then be your car keys, your mobile phone and all other items which are important in the bag. Mitochondria are everything you can’t afford not to care about.

In reality, mitochondria look quite funny. These tiny particles, shaped like rice corn, have a double layer of skin and the inner layer is quite wrinkled! Inside mitochondria, there is a lot of movement and a life of its own is going on in there. Many ingredients keep going back and forth through this inner skin: there is a lot of jumping, shifting, and chaotic bumping all over the place. Certain molecules prefer only one side of the membrane and become cluttered there; this, of course, creates tension. That is enormously important because this tension gets resolved by mitochondria releasing lots of energy.

This energy is delivered in the form of one smart, generic, universally present molecule, called ATP (maybe you’ve heard of it).

Mitochondria are the power plants inside every cell, and this is where CoQ10 comes into play. Inside each mitochondrion, many CoQ10 molecules sit in its inner wrinkles, helping to create the tension.

What is importnat to remember is: mitochondria need plently of CoQ10 to create energy for your eggs.

The more energy-demanding job that a cell does, the more mitochondria it needs. That’s why our hearts have many mitochondria, and ovulating eggs and fertilized embryos are kingdoms of mitochondria.

When we speak about egg quality – by now you’ve realized that it is a lot about mitochondria being able to generate tension, because without tension, there is no energy.

Without energy, there is no healthy egg.

And without a healthy egg, there is no timely ovulation, no good embryo, no good implantation, no good fetus and no healthy baby!

egg quality decreases with age

Decreased egg quality is a natural part of getting old

As we age, our bodies accumulate toxins, mutations, and all kinds of cellular damage.

This inconvenient truth goes for mitochondria, too – by the time a woman reaches 40, almost one third of the mitochondria in her eggs are no longer efficient energy producers.

Understandably, when mitochondria become less functional, this will reflect on egg quality. That’s why women over 35 need to supplement CoQ10 (with a supplement like this for example) to keep mitochondria fit and their eggs in the best shape possible.

So how much extra CoQ10 should a woman take, when, and for how long?

Current evidence suggests that 600 mg CoQ10 taken daily over several months brings significant improvements in egg quality. Most likely to profit from targeted CoQ10 supplementation are older women and women with a diminishing egg reserve.

A 2010 study conducted at TCART (Toronto Centre for Advanced Reproductive Technology) presented evidence for mitochondrial involvement in age-related changes in women’s eggs. Research teams headed by Drs. Bentov and Casper suggest that mitochondrial nutrients should be used as an adjuvant therapy in older women who have difficulties getting pregnant. I cite: “…we believe that supplementing the diets of older women with mitochondrial nutrients may result in an improvement of egg and embryo quality, and subsequently, better pregnancy outcome.

A randomized, placebo-controlled study was initiated in 2009 to test CoQ10 effects on pregnancy outcomes in older women (age 35–43 years). The trial failed to be completed, due to recruitment issues; namely, potential participants (older women) did not wish to waste time and take the risk of being in the study’s placebo group. Another issue is that CoQ10 is a substance already marketed as a food supplement, there is only a limited interest in investing resources in clinical trials with a compound that is not novel and cannot be patented.

One further study on the CoQ10 was initiated by Hadassah Medical organization in 2012, with the goal to explore energy production in eggs from women of older reproductive age. Investigators planned to supplement 600 mg of CoQ10 daily, beginning 3 months prior to fertility treatment, and check outcomes such as energy production levels, embryo quality, cumulative pregnancy, and live birth rate. Large trials like that easily take two years or more, and we can cross our fingers for more new babies due to more CoQ10 research.

In a nutshell, clinical research on the possibilities of improving egg quality is making progress. This is a big step forward, given that only a decade ago most people believed that the quality of women’s eggs was predetermined and could not possibly be changed by any means.

Luckily, targeted CoQ10 supplementation is making its way into clinical practice, giving hope that egg quality can be positively affected not only in women whose ovarian reserve is diminishing due to advancing age, but in all women who want to maximize their chances to get pregnant.
