Soya harms male potency

This conclusion was made by from doctors at Harvard Institute of Health in Boston, USA.

Soya was a long time seen as salvation for diabetics and vegetarians beginners. Soya chocolate, soya meat – those who want to preserve the shape and health and do not renounce their affiliation with pleasure consume these products, thinking that thereby deceiving your body. As it turned out, fans of soybeans substitutes outsmart themselves: a regular intake of soya, even in small amounts, may significantly reduce male potency and as a result lead to infertility.

American doctors came to such conclusion compared the quality of sperm of male fans of soybean and men with average eating habits. It turned that soybean lovers had much lower quality of the sperm, and for such a result is enough to eat, for example, 100 grams of soya meat or soya chocolate bar daily. The negative effect is amplified if a man is overweight or obese.

Then the researchers suspected that the phenomenon is associated with the content in soya isoflavones – a substance which in its structure and effects are like the female hormone estrogen. After experiments on animals, doctors found that increased intake of isoflavones results in specimens of male infertility. However, the evidence that people are facing the same thing, still not there.

And the Americans had reexploration. They interviewed a group of men who regularly consumed soya products following or its contents: curd (tofu), tempeh crisps, sausages, bacon, steaks, milk, cheese, yogurt, ice cream and chocolate. As a result, it became clear that the more soya man gets, the less sperm develops his body. Also confirmed that the extra weight only enhances the effect – because obesity in men contributes to enhanced development of the same estrogen.
