Section

Testosterone

The third area, and the one that connects the first two: a prostate that breaks the night costs you sleep, and sleep is where a good deal of this hormone is produced. Eleven articles — the section is complete. The guide below is the place to start.

Start with the guide

Whether the symptoms point at it

Half the diagnosis is the number. The other half is what you actually came in with, and not every complaint on the usual list carries the same weight.

Getting the measurement right, and reading it

Before the number can mean anything, it has to have been taken properly — and then read against something better than the band printed beside it.

  • The Testosterone Test That Actually Tells You Something

    Afternoon readings in men aged 30 to 40 ran 20 to 25 per cent below the 8 a.m. figure, and repeat measures in the same man can swing by 65 to 153 per cent. Two early mornings is the rule, and fasting is not required.

  • Normal Testosterone Levels by Age: What the Chart Hides

    The harmonised range is 264 to 916 ng/dL, with a median of 531 — in men aged 19 to 39. For the decades in between, the guideline says definitive age-specific ranges do not exist, and a result of 250 can still print as normal.

  • Free Testosterone vs Total: Which Number Describes You

    Everyone tells you to insist on the free number. The guideline says it does not recommend it as the primary diagnostic method, and that the two are not interchangeable. Where it genuinely helps is a band roughly 87 points wide.

What treatment involves

We earn nothing from any of this, which is why we can describe the standard rather than sell a version of it.

  • Testosterone Replacement Therapy: What Each Form Does

    Gels that transfer to other people by touch, injections short and long-acting, implanted pellets. What has to be measured before the first dose, what the largest safety trial found, and the one question that tells you whether a clinic is following the guideline.

  • Testosterone Side Effects: What Shows Up, and When

    Organised by the calendar rather than by category, because that is the question a man on treatment actually has. Sexual interest plateaus at six weeks; red cells peak at nine to twelve months; the one dated risk signal sits in the first six.

  • TRT Clinics: The Evaluation, and the Cost

    A 2022 study found six of seven online platforms prescribed testosterone to a shopper with a normal level and stated fertility plans. What a real evaluation actually includes, and why a year of treatment can cost three to ten times more online than at a clinic using insurance.

Trying it without a prescription

Two things men are told will raise the number, weight loss and sleep, have real evidence behind them. Two others, lifting weights and CPAP, have not moved it in the best studies available.

  • How to Increase Testosterone Naturally: What Works

    Weight loss needs 5 to 10 per cent of body weight and takes months; a week of short sleep alone can drop the number 10 to 15 per cent. Why resistance training and CPAP, the two everyone assumes help, have not moved it in the best studies measured.

  • Testosterone Booster Supplements: What Each One Does

    Zinc and vitamin D work — if you were actually deficient. Ashwagandha has the strongest trial record of the herbs. Fenugreek, D-aspartic acid and tongkat ali have genuinely mixed evidence, ingredient by ingredient, with no blend on any label tested as sold.

The section is finished

Eleven articles, published one at a time. We complete a section before starting the next area, because a half-built section helps nobody.

Where testosterone meets the other two sections

This is one man with one problem showing up in three places, not three subjects.
