Antioxidants Boost Sperm Quality

You'd better eat your blueberries: Men who don't get enough antioxidants can have problems with infertility.

A study published online recently in the journal Fertility and Sterility discovered that men who ate antioxidant-rich fruits and vegetables have better rates of sperm movement, ejaculate volume, and sperm concentration than those who ate diets heavy in meat and full-fat dairy foods.

Antioxidants have been the darlings of the nutritional world as of late — pomegranate juice, anyone? — and possibly for good reason. They are thought to slow the aging process, boost the immune system, and help protect against free radicals, which damage cells and make us more susceptible to degenerative diseases such as cancer, arthritis, Parkinson's disease, and Alzheimer's disease.

And now stronger sperm can be added to the list of benefits.

The research, conducted by several universities in Spain, asked 61 men — 30 with poor semen quality, and 31 with normal semen — to rate the frequency with which they ate 93 different foods. None of the participants took dietary or vitamin supplements during the duration of the study.

The men with normal semen ate significantly more carbs, fiber, and antioxidants, specifically folates, vitamin C, and lycopene, than did the men with the lesser semen.

Does that mean that men who want to improve their sperm should start loading up on antioxidants? Yes, says Jaime Mendiola, the study's head and a researcher at the University of Murcia, adding that the participants were ready to do just that.

"Some of the men were willing to change their eating habits," Mendiola tells LiveScience. "In fact, the next 'ideal' study would be to compare if this change in diet pattern may improve semen quality in case subjects."

So what is the best source of antioxidants? Carrie Bloxson, a New York City-based nutritional health counselor who is unaffiliated with the study, says that eating whole foods is the way to go.

"You should use nutritional supplements just like they are labeled — as a supplement, not a substitute," she says. "I also recommend taking a food-based supplement over a synthetic, as your body will absorb the supplement better because you’re not processing a bunch of chemicals."

Bloxson recommends the following antioxidant-packed foods:

* Folates: spinach, asparagus, and lentils.
* Vitamin C: broccoli, oranges, and strawberries.
* Lycopene: tomatoes, watermelon, and grapefruit.

Happily, research has found that red wine contains antioxidants, too — just another reason to open a bottle on a romantic evening.
