Fertility of woman and man General

How can coenzyme Q10 support your fertility?

coenzyme Q10 in science

Coenzyme Q10 – you may have encountered this term in capital letters on anti-wrinkle creams.
I can’t help but thinking of an old prof of mine who used to say: „ putting coenzyme Q10 on your skin, that’s just like putting a steak on a starving man’s stomach… you have to eat it to benefit from its effects!”

But: What the heck is this coenzyme q10 at all? Why do we find it in anti-aging creams and food supplements? Which effects did that old prof refer to? And how can I benefit from all of this with respect to my fertility?

„Q10 is one of the most important discoveries of nutritional sciences during the past decades.“
Prof. Dr. Linus Pauling, vitamin researcher and 2-fold Nobel Prize laureate

Coenzyme Q10 and cellular energy

Coenzyme Q10 is a fat-soluble component that plays a role in cellular energy-production. In 1957, a biologist first detected it in cattle hearts. Indeed, coenzyme Q10 can be found in almost every cell of our body. More precisely, it is present in the inner membrane of our mitochondria. These are the cell organells responsible for the majority of energy production and are therefore often referred to as “cellular power-plants”. Coenzyme Q10’s main job is to transport electrons from one enzyme complex to another in the respiratory chain. In 1978, British scientist Peter D. Mitchell was awarded the Nobel Prize for chemistry for his landmark discoveries with respect to cellular energy production in mitochondria. Coenzyme Q10, which is also called vitamin Q10 or ubiquinone, and its transport function are a major prerequisite for this main form of energy generation and thus form the basis for our body’s vitality and performance.

Sources of coenzyme Q10

Coenzyme Q10 is partly produced by the body itself. Another part is taken up via our diet. It is abundant in meat, fish, legumes, nuts and seeds, plant oils, crucifers, onions and potatoes. However, cooking quickly destroys it.

Coenzyme Q10-deficiency

Normally, our body has enough coenzmye Q10. However, endogenous production declines with age. This can be observed from approximately 30 years. In addition to that, an unhealthy diet, alcohol and cigarettes lead to decreased endogenous synthesis, as well.
As a consequence, cells have much less energy. Depending on the type of cell, effects vary: skin gets slack, muscles weak, and oocytes and spermatozoa suffer, too. Oocytes usually have diminished quality, spermatozoa show not only a decline in morphology and motility, but also in numbers.

Supplementing coenzyme Q10

The good news: it is simple and not expensive to supplement coenzyme Q10. Once it has reached its target, the cellular power plants, it can revive the process of energy production and contribute to improved energy levels in the body.
Thus, coenzyme Q10 acts a s a true all-rounder. It prevents skin aging from within, and strengthens our heart, nervous and immune system.

Independently, coenzyme Q10 also protects us in its role as as an antioxidant. It helps us to deal with detrimental reactive oxygen species, pro-oxidants that are formed during energy production in our cells. With the aid of antioxidants such as coenzyme Q10, our body can counteract reactive oxygen species, thus preventing oxidative damage to cells and tissues. This helps to stabilize the natural equilibrium between pro-oxidants and antioxidants and delays aging processes.

This is particularly important for healthy fertility, as it is well known that oocytes and spermatozoa are particularly sensitive to oxidative damage.

In conformance with this, studies revealed that supplementing coenzyme Q10 prior to pregnancy can improve oocyte quality in women and sperm quality in men.
In addition to that, there are hints that taking a coenzyme Q10 supplement can also have benefits for maintenance of ovarian reserve.
