That angry, raging warrior, Pete Hegseth is concerned about the testosterone levels of his armed forces.
The implication is that he does not want any low testosterone soldiers around, and, further, that we would be better served by high testosterone level soldiers, sailors and airmen.
The questions here are:
1/ Do higher testosterone levels result in better performance?
2/ What should the goal levels be?
3/ What would you do if you found a soldier who has testosterone levels lower than you think ideal?
Part of the problem here goes beyond science, endocrinology and performance to an issue of language. "He's a low testosterone sort of guy," has become a trope of sorts for a man who lacks aggression, assertiveness, focus, sexual drive--a pale man, who is quiet, docile, who may respond but not initiate.
Those features may, in fact, accrue to men with low testosterone and, in fact, may ameliorate with testosterone therapy, but leaping to the conclusion that those characteristics are simply hallmarks of low levels is wrong. Plenty of men with normal testosterone levels are all of that and giving them more testosterone does not change them.
I would be the last to deny testosterone cannot improve athletic (and by extension, military) performance. The studies which exist, and there are precious few, suggest high levels of testosterone achieved with injections, which raise levels from a normal of a total testosterone of 250-900 ng/dl (depending on the lab and the assay) to over 1200, will reliably increase muscle mass, strength and recovery. Free testosterone levels by mass spec/liquid chromatography are better assays, and they will increase from 50-200 to 200-800 with injections.
Looking at Sammy Sosa, Mark McGuire and Ben Johnson, I thought, "Uh-oh" seeing Sosa's facial acne, Johnson's huge biceps and McGuire's big trapezius muscles.
One of the most common referrals I got in practice was a man who looked like the Incredible Hulk sitting in my exam room who told me he was seeing me for his "low T."
What he had done, of course, was to stop his injections for month and then he got his blood drawn, and his T levels were vanishingly low, because his testicles had shut down while he took injected testosterone. Then he gets his blood test and it's low. Why would he do this? Because he wanted me to prescribe a legal source of testosterone rather than his having to depend on a gym rat compounded version which was expensive and made in somebody's dusty basement.
What Hegseth Sees in the Mirror
The other side of the coin are elite female athletes. For the most part, in the few surveys which are available, elite female athletes have normal total and free testosterone levels for females--15-50 ng/dl. I don't know Caitlin Clark's levels, but whatever they are, she has enough to perform.
The fact is, there are at least 1,500 male track stars across the US who run faster 800 meter races than the world's record for any female runner who has ever run, and there are thousands more male runners across Europe, Africa and Asia who beat the world record for women. Elite male athletes simply are stronger, quicker and faster than elite female athletes. Chris Evert, a sensational woman female tennis player, laughed when she was asked how she would fare playing against Jimmy Connors or any of the great men of her time. "I would not win a game, much less a set." When pressed, she said the power of the serves and volleys among the men was simply overwhelming.
So, I'll take it from her testimony and what little data we have, that testosterone makes a big difference in athletic performance. But there are other factors: male puberty, with it's effects on muscle, bone, brain, tendon is a potent factor.

But here we are talking about huge differences in testosterone levels when we talk about male v female. How much difference differences of 100 ng/dl among a male cohort would make is totally unknown.
Male wrestlers lose weight, train relentlessly and often sleep poorly all of which likely lower their testosterone levels, and yet they are beasts on the mat. Once you get above a certain threshold of testosterone, it's not clear smaller differences matter much: Does a seven foot basketball player really have much advantage over a player who is two inches shorter?
The issue of whether female soldiers are in the same position as Chris Evert is lurking behind Mr. Hegseth's focus on testosterone levels. I would bet on a male warrior in a knife fight, all else being equal (training, size, nutrition), but as we have seen in Ukraine, most war is not fought with knives in the 21st century. Most women soldiers have guns and famously the best snipers of World War II were women.
There has been an online gossip about "steroid rage" among men who have raised their testosterone levels into the stratosphere and then beaten up their wives, friends, policemen, whoever. Maybe that's a real thing. Likely not, but maybe. If it is real, however, the question comes back to General Patton's famous remark to his soldiers: "I do not want you dying for your country. I want you to make that other poor bastard die for his country and we can kill them and win."
Mr. Hegseth seems to have forgotten that rage and a rebel yell do not win wars.
