CoQ10 for Fertility - Coenzyme Q10 for Pregnancy

Coenzyme Q10, also known as CoQ10, is an antioxidant that is naturally found in the body. It can also be taken as a dietary supplement, and it has been recommended for some time as a supplement for men with low sperm count, low motility and other sperm-related problems. Today, there are preliminary studies that suggest that the CoQ10-fertility association could be important for female infertility as well. CoQ10 for pregnancy in women is an area that is actively being researched, with a specific focus on CoQ10 and egg quality. At CHR, we have been using CoQ10 in women with egg quality issues for some time now, based on the results of preliminary human studies as well as studies using animal models.

CoQ10 for Egg Quality

CHR's Medical Director and Chief Scientist, Dr. Norbert Gleicher, explains how CoQ10 can improve egg quality by helping the mitochondria in the eggs.

What does CoQ10 do?

CoQ10 is produced and used in all cells in the human body. All cells require energy to function properly, which is produced by mitochondria (an organelle, a tiny structure inside of a cell, with its own DNA separate from the cell’s DNA). CoQ10 plays an essential role in helping the mitochondria produce energy used by the cells. Specifically, CoQ10 is part of the electron transport chain in mitochondrial cell membranes. CoQ10 is also an antioxidant. In research on CoQ10 fertility, egg quality appears to improve by CoQ10’s action in egg cells during IVF.

Fertility, Egg Quality, & CoQ10

There are two main theories about coenzyme Q10 fertility effects, both of which relate to the molecule’s potential role in egg quality. The important thing to note here first is that the amount of CoQ10 that the body produces declines with age. So, as a woman gets older, all her cells, including her egg cells, have less energy available.

How might CoQ10 improve egg quality? One theory is that because egg cells are so large, and because so much energy is required for fertilization and embryonic cell division, inefficient energy production results in lower egg quality and embryo quality. Less energy in the critical embryonic stage can cause mistakes in cell division, which can lead to failed IVF cycles or miscarriages. By supplementing CoQ10, eggs have a better chance of sufficient energy from its mitochondria to propel its healthy growth.

Another theory relates to CoQ10’s role as an antioxidant. Antioxidant protects cells’ DNA from damages from oxidative stress. When there is less antioxidant activity, free radicals can cause damages to the egg cell’s DNA, which can also lead to egg quality problems. CoQ10 supplementation for IVF can protect those eggs from oxidative damage.

In both of these scenarios, low levels of CoQ10 can lead to problems in fertilization or to an embryo with genetic mutations that interfere with the embryo’s viability. With reduced coenzyme Q10, fertility also declines. Used within well-designed protocols for IVF, CoQ10 have the potential to improve pregnancy chances.

CoQ10 Egg Quality Research

Published research studies on CoQ10 fertility in women and the use of coenzyme Q10 for egg quality are still somewhat limited. Most research is focusing on pairing supplementation with CoQ10 and IVF or IUI treatment for women with infertility, rather than using CoQ10 for pregnancy attempts naturally. The use of the supplement CoQ10 for IVF is similar to how the supplement DHEA is used in concert with IVF, a method that was first established here at CHR in 2005. While published data is limited, CHR physicians have been able to improve pregnancy chances in women with diminished ovarian reserve (whether due to attempting pregnancy after age 40 or due to premature ovarian aging) with supplementation with CoQ10 before and during IVF.
