There is a fair chance a man you know is on testosterone. Around twelve million prescriptions were written last year in the United States, a twenty five fold rise since 2000, and the biggest group is not men in their sixties. It is men between 35 and 44, as John La Puma set out recently in Psychology Today. The clinics have moved online and the screening is minimal. The route in is a feeling: flat. The drive is off, the edge is dull, the recovery is slow. And then the thought that now arrives ready made. It must be my levels.
The public argument about this splits into two camps, and both deserve a fair hearing. One says this is men finally taking their health seriously, decades of avoided doctors giving way to bloodwork and treatment, and it is true that real deficiency exists and genuinely needs treating. The other says an industry has learned to sell ordinary ageing back to men as a disorder, and points to the American Urological Association's estimate that about a third of the men prescribed testosterone are not actually deficient. Notice what the two camps share. Both are arguing about whether the number is really low. Both accept that the number is the question.
The number is not the question. The interesting thing about low testosterone as an explanation is not whether it is accurate in any given case. It is why it is so attractive. A capable man who feels flat at forty has a list of candidate explanations, and almost all of them put a question to his position: the load he has agreed to carry, the sleep that funds it, the pace he calls temporary, the work that pays more than it means. Those explanations are expensive. Not in money, in implication. The number is the one explanation on the list that asks nothing of the position at all. It hands the whole question to chemistry and lets everything else stand exactly as it is. So the flatness, so often a late invoice from the position, gets billed to the nearest cause with a decimal point, and the real cause runs on, unexamined, now behind a better mood. And here the biology does something almost too neat: supply the hormone from outside and the body's own production shuts down. Import the thing you used to make and the factory that made it goes quiet. Explanations work the same way. An answer you import switches off the enquiry you would otherwise have had to run.
I watched the same purchase attempted for years on the trainee floor, in a different currency. It was the capable trainees who went hunting for the one clean, repeatable process, the answer they could take off the shelf and run. The orientation was a real strength, right up until it demanded a certainty the work cannot give. And the search for the perfect process was not preparation. It was a way of avoiding the live, uncertain judgement the job actually required. An imported answer meant the harder question never had to be opened: could a man stand inside uncertainty and read it.
The durable truth underneath the boom is that explanations are priced like everything else, and the cheapest one is rarely the truest. An explanation that asks nothing of your position should be treated the way you would treat any suspiciously cheap quote: as a sign the real cost is somewhere else in the contract. A cost that arrives without a cause attached is information. Buy it a cause too quickly and you do not remove the cost. You remove the information.
None of this says the bloodwork is wrong, or that treatment is never the move. It says the order matters. So the question this puts to you, before the reading gets treated: if the flatness could not be explained by a number, what would it be telling you about the load? And which would cost you more, the prescription, or the answer that is not for sale?
