Found an interesting article on CoEnzyme Q10, and how it can help some women get pregnant.
The part of the article most worth noting:
"Half the mice in the experiment got a placebo, while half got coenzyme Q10; the animals that got the vitamin produced more egg follicles, and more and healthier eggs."
On the downside, the mice were treated with the supplement for the equivalent of a decade in human years.
Still, you never know...
