Phytoestrogens

Male Health

Phytoestrogens can affect male animals health and fertility, what about

people?

 

" For the males, decreased sperm count and enlarged prostates. The

treatment altered virtually every aspect of the reproductive system. The place

next to the testes, the duct system called the epididymis where the sperm are

stored prior to being ejaculated -- it was abnormally small, which could account

also for lowered sperm count in the ejaculate. But we know also the testis is

making fewer sperm. We see changes in growth rate as well. One of the

interesting things is that these very low doses of estrogen increase rates of

growth. The animals were actually growing larger than they would have normally.

It was really quite a dramatic effect. The females went into puberty early. And

we saw changes in behavior, changes in reactivity to the presence of other

animals in the environment. Essentially the animals looked to be somewhat

hyper-reactive to stimuli. We have, in other words, effects on brain and

behavior. We're also seeing changes in liver enzyme activity which determines

the way we respond to external chemicals, how fast we clear drugs, how we

metabolize drugs.

 

In other words, in every aspect of physiology that we look for, we see

effects. And they're permanent. And the important thing about what I'm talking

about is we are only exposing babies to these chemicals for very, very short

periods of time in development and the consequences are for the rest of the life

of that individual. Once you change the development of an organ there is no way

to undo that effect. It's a life sentence -- that's a lifetime consequence.

Medical science can't undo the development of organs. " Fredrick Vom Saal,

Professor of Biological Sciences, University of Missouri in an interview on

estrogenic chemicals in the environment conducted in February 1998 by Doug

Hamilton, producer of FRONTLINE's " Fooling With Nature. " Full interview can be

From simple laboratory mice to the unusual case of the phytoestrogen

sensitive captive cheetahs, there is ample evidence that dietary phytoestrogens

cause infertility in a variety of animals. Why would this be? Like the other

toxins in soybeans, the phytoestrogens are present in the soybean to ensure its

survival. What better way to discourage predators than to make sure they

aren't able to reproduce?

 

But what about humans? Some, such as Richard Sharpe and Theo Colborn,

have suggested that the trend toward lower male fertility is due to

environmental estrogens, including the soy phytoestrogens. But is there any

evidence that phytoestrogens may place males at risk of reduced fertility? Also

see quotes from Food Safety - a 21st Century Issue, by Professor Shaw in the New

Zealand Science Review. The human sperm count decrease over the past five

decades might relate to the introduction of soya to the western diet and the

increasing popularity of vegetarianism - a sting in the tail for apparently

healthy eating. More information is available from an article published in The

Dominion, Wellington September 3 2001.

 

Nagata and colleagues have reported an inverse association between soy

product intake and serum hormone concentrations in Japanese men. Research has

demonstrated that chemical compounds can have a number of other effects on male

health including decreasing prostate gland weight, lower testosterone levels,

along with inducing significant testicular cell death and necrosis.

This and other articles you have posted (that I've seen) have been

excellent. Please keep up the good work.
