Coenzyme Q-10 is a naturally occurring chemical found in the parts of the cells (mainly the mitochondria) that produce energy, and is thought by some to be helpful for certain diseases such as cancer, heart disease and some neurologic diseases. A recent study suggests that using Coenzyme Q-10 as part of IVF (In vitro fertilization) may increase the percentage of embryos that are genetically normal. We know that genetically abnormal embryos (which is actually most embryos transferred) explain most IVF failures and miscarriages, so anything that might increase the number of generically normal embryos may improve a couple’s odds for success. A word of caution: this study is too small to draw any conclusions. Further research is needed to determine if Coenzyme Q10 is effective or not.
