CoQ10 and Fertility – Can It Help Me?

What is CoQ10?

CoQ10 is a supplement that is similar to a vitamin. It affects cells by producing energy via the cell mitochondria. It can also prevent cell damage as it acts as an antioxidant.

Production of CoQ10 decreases as we age. When the CoQ10 in the cells lowers, energy production can also be lowered and increase oxidative stress on on sperm and eggs.

CoQ10 and Egg Quality

CoQ10 studies have demonstrated improved egg quality in women with poor egg quality or advanced reproductive age

Researchers believe that the CoQ10 recharges mitochondria in eggs and reinforces the processes for successful fertilization of the egg.

CoQ10 and Its Effect on Sperm

Taking CoQ10 for a number of months can help with sperm count, morphology and motility according to studies.

Sperm count is the number of sperm in a sample, motility is the way that sperm ‘swim’ by moving their tails, and morphology is an indication of whether the sperm are shaped and sized properly.

Dosages

Women
In the studies, the recommended dosage was between 100mg and 300mg per day. The studies, researching egg quality, used dosages up to 600mg a day.

Men
Sperm studies dosage was 200mg daily.

Important to Know

CoQ10 is better taken with meals that contain fat or oils, as the supplement is fat soluble.

As with all supplements, talk to your healthcare provider before starting to take it as it can react with some prescription medications and can have some side effects.

Possible side effects include, but are not limited to:

  • nausea
  • heartburn
  • rash
  • insomnia
  • irritability
  • fatigue
  • increased sensitivity to light
  • flu-like symptoms.

Lower blood sugar and blood pressure have been reported after taking CoQ10, so talk to your doctor before taking it. If you have hypoglycemia or are diabetic, talk to your doctor first. Studies have also shown that supplementation over 300mg a day may result in higher liver enzyme levels if taking for an extended time period.
