Excess weight reduces men’s fertility

Excess weight reduces men’s fertility. Obese men are more likely to be infertile than their slimmer peers, according to the first study to look at whether a man’s weight influences a couple’s fertility. Every excess 10 kilograms, may cut a man’s fertility by a certain percentage.

The researchers looked at couples who had attempted pregnancy over the past four years. The analysis was limited to couples for whom the wife was younger than 40. The researchers compared the men’s body mass index (BMI), a measure of weight in relation to height, to pregnancy success. A BMI of over 25 is considered overweight. Infertility was defined as failure to become pregnant after 12 months of unprotected intercourse. Fertility was lower among men with BMIs of 26 or greater, and decreased as BMI rose, Sallmen and colleagues found. For every three points increase in BMI, the risk of infertility rose by 12 per cent.

Increased dietary fish oil may prevent heart diseases

FISH OIL could potentially save more lives than cardiac defibrillators, devices used to revive individuals whose hearts have stopped beating and prevent and treat life-threatening heart arrhythmias, a new study says. Past research has linked the omega – 3 fatty acids found in oily fish to a lower risk of fatal heart rhythm disturbances. The latest study tried to estimate the potential public impact of raising adult’s omega – 3 levels with fish oil supplements.

Using a computer-simulated community of 100,000 American and data from past medical studies, the researchers calculated that raising omega – 3 levels would save 58 lives each year.
