Ok - this is what I was just reading about Co-enzyme Q10 in a fertility related source.

"Helps with fainting, dizziness and obesity. An important nutrient within the body's energy production process. Has proven useful in controlling blood sugar - best known as a healthy-heart supplement. Usual dose in 60mg capsules twice a day. Ideally should be taken under the guidance of a nutritional therapist."

It is certainly not the first thing I think of taking when trying to improve fertility.

I think if you are looking an improving DH's dodgy army - you may need to look at other things like zinc and Vit C. For yourself there are probably other nutrients recommended for supporting egg production. Most common recommendations I have read about are B complex, zinc, vitamin E.

Have you consulted a nutritional therapist or naturopath? Usually best to do these things under supervision and with proper advice.

Good luck with it all.
