Testosterone Collapse: One more Seneca Cliff

Chemical Pollution and Human Survival

A guest post by Lukas Fierz, who discusses the decline in human testosterone and correlates it to other problems caused on the human reproductive capability by chemical pollution. He concludes that we face a “reproductive Seneca Cliff.” Humans may not be able to reproduce themselves anymore before the end of the 21st century. He says, “This is a progressive chemical castration. Being a severe bodily harm, it should be prosecuted ex officio. But, surprisingly, there is not even a public outcry, probably because the media steadfastly refuse to publish anything about it.”

A Guest Post by Lukas Fierz, M.D.

Decreasing sperm counts will interfere with human reproduction starting from the middle of our century. The decrease is worldwide and has accelerated to over two percent per year, as shown in 200+ studies on 50’000+ men. The total loss since 1950 exceeds 50 percent.

Male testosterone also declines by one percent per year according to seven out of eight long-term studies from Europe, Israel, Brazil, and the US. Several non-systematic studies confirm a downward trend: e.g., 40 percent loss during 30 years in the American Midwest.

Testosterone decline must be similarly widespread as sperm decline and probably also accelerating because both share common causes: Pesticides and phthalates (the plasticizers we get from food packages and cosmetics) affect not only sperm but also testosterone by disturbing testicular development in the male embryo. Moreover, any decline in testosterone diminishes sperm production. E.g., one kilogram of extra weight costs a man one percent of his testosterone (and one year of remaining potency) and thereby also decreases his sperm count.

After removal of one testicle (hemicastration), the other one takes over and sperm and testosterone return to normal within months. Therefore, the observed 50 percent reduction amounts to much more than a hemicastration. It brings some men already into female territory.

This is a progressive chemical castration. Being a severe bodily harm, it should be prosecuted ex officio. But, surprisingly, there is not even a public outcry, probably because the media steadfastly refuse to publish anything about it.

A decline in testosterone must have many behavioral and societal effects, since testosterone during development determines male body type, sexual identity, and orientation, and later not only sustains male sexual interest and behavior, but in all vertebrates (starting with fish) also activates maintenance and defense of a territory.

And indeed, we already find not only an increase of male genital malformations but many behavioral consequences of testosterone decline: Impotence in young men is on the rise, while measured sexual activity decreased in Germany, France, US, and Australia. The longest observation time comes from the UK, with a decrease of the median of sexual activity by 40 percent in 30 years. Also clearly on the rise are asexuality, single life, bisexuality, and other blurrings of sexual identity and orientation. Last but not least reduced sexual interest and activity must contribute to falling birth rates.

While one can sympathize with tendencies to abolish military service and armies, it is quite possible that these are also caused by testosterone decline.

When Germany in 2015 accepted one million refugees without even trying to check their origin, identity, or cause for being a refugee, I wondered if this obvious failure of territorial control could be because Chancellor Merkel, being a woman, lacked territorial reflexes. In retrospect, it is difficult to resist the view that this could have been another consequence of testosterone decline.

While a reduction of human fertility and aggression has positive aspects, the same plasticizers and pesticides that interfere with testicular development also interfere with the developing brain, causing disturbances of attention, learning, and behavior. This might have a relation to the observed school problems and declining PISA results.

All this adds three more Seneca cliffs.

1. Reproductive drive and reproduction are already being reduced by testosterone decline, probably accelerating in a Seneca style.

2. Reproductive capacity may face a collapse caused by the ongoing and accelerating sperm decline.

3. Our developing brains are already being dumbed down by chemicals and later they will also be subjected to narcosis by increasing CO2 levels.

Since the process of chemical castration seems to go on unnoticed and unchecked, we steer towards a society governed by eunuchs. While history does not repeat itself, it may rhyme, and one remembers the downfall of other empires governed by eunuchs, e.g., Byzantium, the Ottomans, or ancient China.
