What did the Testosterone Trials find in men 65 and older?
The Testosterone Trials are the clearest answer we have. They enrolled 790 men aged 65 or older whose testosterone averaged under 275 ng/dL and who had symptoms, then gave them testosterone gel or a placebo gel for one year. The main results in the New England Journal of Medicine and the companion studies break down like this:
| Outcome | What testosterone did over one year |
|---|---|
| Sexual function | Significantly more sexual activity, desire and erectile function |
| Bone | Spine trabecular bone density rose 7.5% versus 0.8% on placebo |
| Anemia | Hemoglobin rose by 1 g/dL or more in 54% of men with unexplained anemia, versus 15% |
| Mood | Slightly better mood and fewer depressive symptoms |
| Walking distance | No significant gain in the trial built to test it |
| Vitality | No significant benefit on the fatigue scale |
| Memory | No improvement in memory or other thinking skills |
Which benefits held up, and which did not?
Sexual function, bone density and anemia held up most clearly. The bone study of 211 men found gains in density and estimated strength, largest in the spine. In the anemia study, 58% of men with unexplained anemia were no longer anemic at 12 months, compared with 22% on placebo.
Memory did not. A review of all seven trials confirms that testosterone did not improve cognitive function, and only slightly improved walking distance and vitality. If your main hope is sharper recall or more stamina, the evidence in this age group is thin.
Stronger bones on a scan also did not translate into fewer broken bones. In a later TRAVERSE fracture analysis of men aged 45 to 80, clinical fractures occurred in 3.50% of men on testosterone and 2.46% on placebo over about three years. Our summary of the Testosterone Trials in men over 65 goes deeper into each result.
What extra checks do older men get?
Older men get the same diagnosis rules as everyone else plus a closer look at risks that rise with age. The Endocrine Society guideline suggests against routinely treating every man over 65 with low testosterone. Instead, it suggests offering treatment individually to men with symptoms and consistently low morning levels, after an open talk about benefits and risks.
| Check | Why it matters after 65 |
|---|---|
| PSA and prostate history | The trials saw PSA rise and more urology referrals on testosterone |
| Hematocrit | Some men developed too many red blood cells; six reached hemoglobin above 17.5 g/dL |
| Heart and blood pressure | Testosterone slightly increased non-calcified coronary plaque in one trial |
| Fracture and fall risk | Bone density gains did not lower fractures in TRAVERSE |
| Sleep and medicines | Untreated sleep apnea and some medicines change the plan |
Our pages on the PSA blood test and hematocrit explain each marker.
Is age alone a reason to say no?
No. Age is a reason to be more careful, not a reason to refuse. A healthy 68-year-old with low libido, unexplained anemia and two clearly low morning tests is a different case from a 68-year-old with heart failure and a rising PSA. The question is always the specific man.
It also helps to separate low testosterone from normal aging. Our page on whether TRT is FDA-approved for age-related low T covers how regulators view that distinction, and the guide for men over 60 collects related topics.
How Ultimate Male evaluates men over 65
For older men, the first visit leans heavily on history: heart disease, urinary symptoms, falls, bone density results and every medicine you take. The TRT pre-screening panel checks total testosterone, estradiol, PSA and a complete blood count, drawn on site at San Gabriel or Downey, and a repeat morning test confirms the number.
If the case for treatment is solid, the plan starts conservatively, with closer early follow-up on PSA and hematocrit and coordination with your primary care physician. If it is not, you leave with a clear explanation instead of a treatment unlikely to help.
