Sex Hormones
Prolactin on TRT
What the number means, why it moves on a protocol, and how it sits with related markers.
What it is
Prolactin is a pituitary hormone. In men it normally stays low; when it climbs it can blunt libido, erections and mood.
The range
How to read the lab range
Labs quote roughly 4 to 15 ng/mL (85 to 320 mIU/L). Mildly above that is common after stress, poor sleep or sex before the draw. A clearly high result is one to raise with your doctor.
Why it moves on a protocol
- Stress, poor sleep, and an orgasm in the hours before the draw.
- Some medications.
- Rarely, a pituitary adenoma.

Questions people ask
Why can one prolactin result read high?
It reacts to stress, poor sleep and sex in the hours before the draw, so a single mild rise often has a simple cause. Your doctor will know whether it needs a repeat.
Does TRT raise prolactin?
Testosterone alone does not, or barely. A rise on plain TRT usually has another cause.
