Andropause is the catchier name for late-onset hypogonadism, which is the clinical term for low testosterone in older men. It’s a real condition, it does affect a meaningful percentage of men over 50, and the diagnosis and treatment have been completely overrun by a wellness industry that’s selling TRT (testosterone replacement therapy) to anyone with a credit card and a vague complaint of fatigue. Telling the legitimate cases apart from the marketing-driven cases is most of the work, and it’s the part of the workup that the cash-clinic version is structurally designed to skip, because doing it properly slows down the conversion funnel and the conversion funnel is what the business model runs on.

What it actually is, biologically

Testosterone declines with age in men. The decline starts in the late 20s, runs about 1% a year on average, and accelerates a bit after 50. That’s normal aging and is not, by itself, a disease. Most men in their 60s have testosterone levels that are lower than they were at 25 and are completely fine, getting through their days, enjoying their lives, having sex, lifting things, none of which requires the testosterone level of a 25-year-old to accomplish.

Late-onset hypogonadism is when the levels drop enough that you start having actual symptoms, and the symptoms are bad enough to be worth treating. The classic symptom cluster is low libido, erectile dysfunction, low energy, low mood, loss of muscle mass, increased body fat, sometimes hot flashes, sometimes gynecomastia (breast tissue growth, the awkward kind), sometimes osteoporosis. The catch is that almost all of those symptoms can be caused by ten other things, so just having the symptoms isn’t enough to make the diagnosis. The symptoms are the prompt for the workup, they aren’t the diagnosis on their own.

Clinical eligibility for TRT, and the part that gets skipped

Legitimate TRT candidates have: two morning T levels under 300 (some clinicians use 250 as the cutoff, the guidelines aren’t fully aligned on this), symptoms that match, and other causes ruled out. The other causes that need actually ruling out are real ones… sleep apnea, obesity, opioid use, chronic illness, depression itself (which suppresses T), pituitary issues (the gland in your brain that tells the testicles to produce testosterone, and which sometimes has its own problems). The workup before starting TRT should include LH and FSH (the two pituitary hormones that signal the testicles to produce testosterone, and which tell you whether the problem is at the testicle level or upstream at the pituitary level) to figure out whether the problem is primary (testicular) or secondary (pituitary/hypothalamic). Secondary hypogonadism in particular sometimes needs a different workup, like an MRI of the pituitary, before treatment.

Once you start TRT, you’re committing to long-term treatment, and that’s a real commitment. The body stops making its own T once exogenous T is supplied, the feedback loop turns off, and coming off the medication usually means going back to baseline-or-worse for months while the system re-engages itself. Some patients never fully recover endogenous production. So this isn’t a casual experiment, it’s the kind of decision you want to make after the full workup, not after a one-page lab and a 10-minute video visit.

You also need to be screened for things TRT can worsen: prostate cancer (TRT doesn’t cause it, but it can accelerate existing undetected cancer), severe sleep apnea (TRT can worsen the apnea), erythrocytosis (TRT can drive your hematocrit, the percentage of your blood that’s red blood cells, up to levels that thicken the blood enough to be a stroke risk). Regular lab monitoring is part of being on TRT, not optional. Every three to six months in the early phase, then yearly once stable. If your TRT clinic isn’t running those labs, that’s a flag.

The TRT clinic grift, called by its name

The wellness-clinic version of TRT skips most of the workup. You fill out a form, you get one lab drawn, you get prescribed testosterone, sometimes alongside HCG (human chorionic gonadotropin, used to keep your testicles producing some of their own hormones and to preserve fertility) and anastrozole (an aromatase inhibitor that blocks the conversion of testosterone to estrogen, used to manage some of the side effects of TRT) and a bunch of other stuff to manage the downstream effects of the testosterone they just put you on. The clinic makes money on the prescription and on the monthly injections and on the labs they run quarterly. Whether you actually needed TRT is somewhat beside the point of the business, and the model is structured to make sure that question doesn’t slow down your enrollment.

This is not categorical opposition to TRT. TRT is a real treatment for a real condition, and the right move when the workup confirms genuine hypogonadism. The framing matters. TRT is a serious long-term medical intervention, not a wellness supplement, and the difference between the legitimate version of treatment and the cash-clinic version is most of the safety margin. The cash-clinic version isn’t necessarily killing anybody this week, the cash-clinic version is structured so that nobody’s watching for the thing it might cause five years from now.

What TRT actually does and doesn’t do

For patients with genuine hypogonadism, TRT usually improves libido within a few weeks (this is the fastest effect and the most reliable), energy within a couple of months, muscle mass and body composition over six to twelve months. Mood often improves. Erectile function may or may not improve depending on what else is going on with the vascular system underneath it.

What it doesn’t do: it doesn’t make you younger, it doesn’t replace exercise and a decent diet, it doesn’t reliably build muscle on guys who don’t lift, and it doesn’t fix ED that’s primarily vascular. The patients who report life-changing TRT effects usually report them in combination with the lifestyle changes they made when they finally decided to take their health seriously, and untangling how much of the change was the testosterone versus how much was finally going to the gym is genuinely hard to do honestly. The story patients tell themselves is “TRT changed my life.” The actual sequence was usually “I started taking care of myself and TRT was part of the package.” Worth being honest about that, because it changes what other guys can reasonably expect.

What’s nice to hear about TRT done correctly

For patients who actually meet criteria and get the full workup and end up on a properly monitored TRT regimen, the outcomes can be substantial. Libido comes back, the morning energy comes back, the muscle responds to lifting in a way it had quietly stopped doing, mood lifts. The patients who do this right and stay on the labs and don’t try to combine it with the rest of the wellness-clinic supplement stack usually report it as one of the better medical decisions they ever made. The fix is real for the patients it’s the right fix for. The screen-out work is mostly to keep the patients who’d do better without it from ending up on a long-term injection regimen they didn’t actually need.

Order of operations matters, and the cheapest fix usually comes first

The pattern that comes up most, and picture a case like this: a patient walks in for low energy and “feeling like an old man.” Lifelong active, recent decline in libido, slowly putting on weight around the middle, sleeping more but waking up tired. He’s already been to a wellness clinic that wanted to start him on T at his second visit. He wants a second opinion before signing up for years of injections.

The full workup goes in. Two morning labs come back with total T around 240 and 265, free T low. LH on the lower end of normal, suggesting the issue is more secondary than primary. The sleep study shows moderate sleep apnea, AHI of 24. Thyroid is fine. Cortisol is fine. No opioids. No signs of pituitary tumor on the screening history.

Treat the sleep apnea first. CPAP for three months. Recheck labs: T comes up to 380. He’s reporting about 50% better just from sleeping properly. He still has some residual hypogonadism, so we do start TRT, weekly injections, conservative dose, regular labs. Six months later he’s lifting again, his energy is back, his libido is where he wants it. Labs every six months. The order of operations mattered. If we’d just thrown TRT at him without fixing the apnea first, we’d have made his apnea worse (TRT can do that) and missed the cheaper fix that did most of the work.

TRT is a serious long-term medical intervention, not a wellness supplement. The cash-clinic version is structured so nobody’s watching for the thing it might cause five years from now.

What you should know if you think you might have low T

If you think you might have low T, the workup is the part that matters more than the prescription. Morning labs twice, full evaluation for other contributors, ruling out sleep apnea and obesity and depression and medications that suppress T. If after all that you still have legitimate hypogonadism with matching symptoms, TRT is a reasonable option done correctly with monitoring. If you skip the workup and start TRT through a clinic that treats it like a wellness supplement, you may feel better for a while and you’re also taking on real risks without anyone watching for them, which is a deal that looks fine in year one and not as fine in year five.

Where this lands

Andropause is real, the diagnosis requires actual labs and a proper workup, and the legitimate treatment is different from what the cash-clinic version is selling. Most patients who think they have low T have either subclinical numbers that don’t actually meet criteria or have a fixable underlying problem like sleep apnea or obesity that would resolve the symptoms without needing replacement at all. Get the workup. Then if you actually need TRT, do it carefully, with monitoring, with somebody who isn’t running the protocol off a script written by a marketing department.
