The manly hormone evolved 500 million years ago — from estrogen.
1. Testosterone is produced in men’s testicles, women’s ovaries and the adrenal glands of both sexes. In the early weeks of pregnancy, it kicks off the development of reproductive organs for males.
2. After birth, testosterone plays a role in regulating processes from fat distribution to red blood cell production.
3. Long before the hormone was discovered, people ascribed youth-restoring powers to the testicles. Roman naturalist Pliny the Elder noted the sexually stimulating effects of dining on hyena genitals (with honey, of course).
4. Honeyed hyena testes sound preferable to the handiwork of Kansas huckster John Brinkley, who inserted slices of goat scrotum into men’s testicles in the 1920s, claiming it would boost virility and cure a host of ailments.
5. Despite its association with male virility, testosterone can also enhance a woman’s libido by targeting receptors in a section of the brain responsible for sexual activity. 6. Sex hormones, including testosterone, evolved 500 million years ago — before the first vertebrate animals — from the “mother” of all steroid hormones, estrogen.
7. But testosterone is, relatively speaking, a manly hormone. Normal levels for women are 5 to 7 percent of those for men. 8. Testosterone levels decline with age. Fifty percent of men in their 80s have testosterone levels below the normal adult male range.
9. One thing that’s not declining: demand for testosterone. In 2010, 1.3 million patients in the U.S. received a prescription for the hormone. That number jumped to 2.3 million in 2013.
10. Age isn’t the only cause of low testosterone; obesity is, too. With more body fat, more testosterone gets converted to an estrogen called estradiol, which further inhibits testosterone production.

old men were/are grumpy.....Go screw yourself and stay off my lawn.
I’m old and happy....what does that mean?
Now you know where the old saying “it’s hell to get old” came from.
Probably means you divorced your wife and you now live alone?
Maybe you should change your orientation ?
Nope! But I do have a dog.....
So I should face south instead of north?
Just face it...I’m just more manly than you guys!
If I make a statement and no woman heard me, am I still wrong?
Yo, Testosterone!
You got a problem, with that, Buddy !?!?!
(Just kidding)
It does not make me grumpy. I am naturally grumpy.
And it apparently, makes your hair fall out. Until it starts growing in places it’s never grown before. And who the hell came up with that brilliant idea?
I mean - seriously! I got some hair growing out of the rim (is that the right word) of my ears, and it grows like a frick’n weed! WTH!?
Who Ordered This?
Why hyenas? Why choose a species where the males are built like Barack Obama, and the females resemble Michelle? If there is one species where you *don’t* want to emulate the males of, it would be hyena (unless you are aiming for “metrosexual”).
NO!
I take testosterone supplement in the form of a cream you rub on...before that, in pill form.
Used to use patches, injections are the worst.
If you forget and miss a few days you can get a bit tired.
It’s all good. :)
Ha,Ha, I’ve been saying for a number of years, that guys don’t go bald, the hair just shifts to growing other places,
As the article noted, obesity and low T are a vicious circle, but it also works in reverse. Increasing dietary and sleep habits can affect testosterone levels and the increasing lean body mass contributes to more efficient testosterone production.
A few years ago I did a lot of reading on the subject and made a few changes that have had an overwhelmingly positive effect.
- Peak testosterone production occurs in deep sleep. Males approaching or over 40 should target a full 8 hours of sleep each night. It’s hard and takes a lot of discipline, but it has worked very well for me. I generally work 9-10 hour days and like my reading decompression time, but have given up some of that to enforce a rigorous sleep schedule with few exceptions.
- While the FDA seems adverse to homeopathy a number of European agencies have researched saw palmetto. One of the benefits they’ve found is that there are chemicals in saw palm that will bind with and inhibit some female hormones in the body which would otherwise bind with and neutralize testosterone.
There are a few other things I do but those alone have made a big difference...
I have one hair that grows off the top of my ear. It’s not a gray hair, so I got that going for me at least.
