Taking antioxidants may go a long way to help couples trying to conceive, especially if the male partner's sperm count or quality is the problem, according to a new study from New Zealand.

Sometimes Nutritional Supplementation Is Enough to Enable Men to Become Fathers

Researchers took a look at over 30 studies involving the use of safe, common, and inexpensive antioxidants and the results in men's fertility. The New Zealand research team used a statistical technique called meta-analysis to eliminate sampling error, the inaccurate results in medical studies that can occur when the men participating in a study aren't representative of men in the world at large.

What the data showed is that:
  1. Men in fertility treatment programs who take antioxidants are four times more likely to get their partners pregnant.
  2. Men in fertility treatment programs who take antioxidants are five times more likely to become fathers of a live, healthy baby.
Antioxidants not only help couples conceive, they help couples conceive healthy babies. And for just pennies a day, why wouldn't any man trying to become a father take a daily dose of vitamin E (400 IU a day) or zinc (30 mg a day) with copper (1 mg a day)? The meta-analysis done by the fertility researchers in New Zealand does not tell us for sure, but the answer may be that antioxidants help men who are nutritionally deficient in the supplements they take, but not men who already have enough of the antioxidants in their systems. However, there are some men who are chronically deficient in antioxidants.

Male Fertility Cases Especially Helped by Antioxidant Supplements

Certain men are almost guaranteed to have low antioxidant levels. These include:

  • Smokers,
  • Men who use street drugs on a regular basis,
  • Men who have had chemotherapy,
  • Men who have physical damage to their testicles or scrotum,
  • Men who are regularly exposed to chemicals, such as gasoline, industrial cleaning agents, dyes, etching chemicals, fertilizers, pesticides, herbicides, and
  • Men who have been exposed to or treated with radiation.

However, restoring antioxidant levels by taking moderate doses of vitamin C, vitamin E, beta-carotene, or resveratrol and by eating five or more servings of vegetables every day will not help men who do not make any sperm at all. (And taking megadoses of these supplements makes them pro-oxidants, canceling out their antioxidant effects.) Antioxidants help men who have "subfertility," not infertility.

Instead, the men who are most helped by antioxidants are those who have problems with sperm motility, or "swimming ability." The one- to three-day journey from the cervix to the egg requires the sperm cell to expend a great deal of energy. Burning sugar in the cell builds up toxic levels of free radicals left over from the energy-making process. Men who take antioxidants make sperm that have the antioxidants they need to survive the trip to the egg.

Men who have had damage to the seminal duct, or who have a condition called varicocele (enlargement of the vein across the scrotum), are especially helped by selenium. Other men who have issues with sperm motility are helped by taking vitamin C, copper and zinc together, vitamin E, and by eating at least five servings of plant foods each and every day.
