Loss of Virility Associated with Soy and Veganism

In my book on chronic fatigue, a key point is the deleterious effects of inadequate protein in the diet. This is the main reason veganism is a bad health strategy. Some people have to learn this the hard way, by becoming sick. (For the record, a vegetarian diet that includes sufficient quantities of animal protein, such as from eggs and dairy, can probably avoid the problems of a vegan diet.)

Some vegans, like the one below, compound their problems by using soy as a source of protein. Soy contains estrogen-mimicking chemicals, and probably shouldn’t be consumed at all.

Note that this man was young, 19 years old, so he should have had the virility normal to a man of his age. One thing here that’s a little surprising is that it took a year after cessation of the vegan diet to regain complete virility. I would have thought that it wouldn’t have taken that long, but who knows what he was eating. Like many people, he probably had a fear of fat and of meat and other animal products, and didn’t eat enough.

Hypogonadism and erectile dysfunction associated with soy product consumption.

Abstract
Previous research has focused on the beneficial effects of soy and its active ingredients, isoflavones. For instance, soy consumption has been associated with lower cardiovascular and breast cancer risks. However, the number of reports demonstrating adverse effects of isoflavones due to their estrogenlike properties has increased. We present the case of a 19-y-old type 1 diabetic but otherwise healthy man with sudden onset of loss of libido and erectile dysfunction after the ingestion of large quantities of soy-based products in a vegan-style diet. Blood levels of free and total testosterone and dehydroepiandrosterone (DHEA) were taken at the initial presentation for examination and continuously monitored up to 2 y after discontinuation of the vegan diet. Blood concentrations of free and total testosterone were initially decreased, whereas DHEA was increased. These parameters normalized within 1 y after cessation of the vegan diet. Normalization of testosterone and DHEA levels was paralleled by a constant improvement of symptoms; full sexual function was regained 1 y after cessation of the vegan diet. This case indicates that soy product consumption is related to hypogonadism and erectile dysfunction. To the best of our knowledge, this is the first report of a combination of decreased free testosterone and increased DHEA blood concentrations after consuming a soy-rich diet. Hence, this case emphasizes the impact of isoflavones in the regulation of sex hormones and associated physical alterations.

DHEA levels increased?

This might just be a case of confirmation bias, but the “N=1” nature of this study doesn’t phase me.

We can’t be sure in this case (Diabetic) what was originally the cause of the anomaly. It makes sense to track the effect of isoflavones in healthy subjects. ED is a side effect in Diabetes, with or without isoflavones.
