Testosterone
Testosterone affects energy, muscle, bone density, mood and libido in both men and women. Levels vary a lot by sex, age and time of day, so a single number only means something next to the right reference range.
Your reading
Daygo shows the range printed on your own report, because it differs by sex and lab. In men, levels are highest in the morning and can be lowered by poor sleep, excess weight, heavy drinking and very hard training. A low result is usually re-tested on a second morning before any conclusion.
What may help
- —Sleeping 7–9 hours: even one week of short sleep measurably lowers testosterone
- —Strength training and losing excess body fat
- —Testing between 7 and 10 am, when levels peak
When to talk to a doctor
If two morning tests are low and you have symptoms like low energy, low libido or loss of muscle, or if a woman's level is high with irregular cycles or acne.
