Re: Mobile phone round up

Sorry to disagree, but.

Soya's likely link to male infertility in Europeans, strangely not it seems Asians, has been widely reported in both the German and International press this week.

Here's something from the BBC in English:

Soy foods 'reduce sperm numbers'

A regular diet of even modest amounts of food containing soy may halve sperm concentrations, suggest scientists.

The study, published in the journal Human Reproduction, found 41 million fewer sperm per millilitre of semen after just one portion every two days.

The authors said plant oestrogens in foods such as tofu, soy mince or milk may interfere with hormonal signals.

Animal studies have suggested that large quantities of soy chemicals in food could affect fertility, but other studies looking at consumption in humans have had contradictory findings.

The Harvard School of Public Health study looked at the diets of 99 men who had attended a fertility clinic with their partners and provided a semen sample.

The men were divided into four groups depending on how much soy they ate, and when the sperm concentration of men eating the most soy was compared with those eating the least, there was a significant difference.

The "normal" sperm concentration for a man is between 80 and 120 million per millilitre, and the average of men who ate on average a portion of soy-based food every other day was 41 million fewer.

Dr Jorge Chavarro, who led the study, said that chemicals called isoflavones in the soy might be affecting sperm production.

These chemicals can have similar effects to the human hormone oestrogen.

Genistein present in Soya has long been linked to sperm damage.

There is almost nothing in life that someone somewhere hasn't claimed is bad or potentially harmful to your health.

"There is almost nothing in life that someone somewhere hasn't claimed is bad or potentially harmful to your health."

Yes but having a cavalier approach to proven health hazards is not the answer. Smoking for example is a proven health hazard yet people still smoke with the "I know someone who smoked like a chimney and lived to 95" argument. The fact that they end up with emphysema themselves is of no consequence at that point in their life. I'd rather be healthy.

Re: Mobile phone round up

Hans, you are quite right with the sperm levels thing, but the twist in this is the link (among other things) between testosterone and cancer cell proliferation.
This really is a very complicated topic indeed, and there are pluses and minuses, whereas with mobiles it is a different matter.
