Couples who are trying to conceive could find help in blueberries and tomatoes. A new review of over 30 studies says that the antioxidants found in those foods, may improve male fertility:

The researchers focused on men who were subfertile — less fertile than average but still capable of making a baby — and found that those who took antioxidants were more than four times as likely to get their partners pregnant than subfertile men who did not take the supplements.

The New Zealand team stops short of saying that antioxidants actually improve fertility, however. More research is needed to be sure.

Research published in the journal Occupational Medicine shows men are more likely to succumb to a cold than their female colleagues when under stress at work. Scientific proof guys are wimps when they're sick:

One explanation could be that "males were significantly more likely to overrate common cold symptoms than females," the research team from Ajou University School of Medicine, South Korea, said.

"Therefore any association between work-related stress and the common cold may be accentuated in males by their reaction to experiencing a cold — and attenuated in females by their more stoical response."

Researchers say that skipping a night of sleep takes the same amount of energy as it does to walk about two miles. Still, experts warn sleep deprivation should not be used as a form of weight loss:

Alternatively, looked at in terms of food, a night of sleep deprivation can be translated into losing about 135 calories — about the amount found in two slices of bread or a nearly eight ounces of semi-skimmed milk.

"While the amount of energy saved during sleep may seem small, it was actually more than we expected," study author Professor Kenneth Wright, director of Colorado University’s Sleep and Chronobiology Laboratory, said in a news release.
