Non-randomised trial, 1984
Does progesterone treatment change hormone binding in severe PMS?
Yes, progesterone increased SHBG binding capacity in a dose-dependent way. Higher doses produced larger increases. The abstract does not say if this helped symptoms.
What they did
Gave 31 women with severe PMS different doses of progesterone (400 mg, 800 mg, or 1200 mg daily) and measured changes in SHBG binding capacity.
What they found
Baseline SHBG binding capacity was 30.2 nmol DHT bound/l. After 400 mg progesterone it rose to 45.11. After 800 mg it rose to 64.75. After 1200 mg it rose to 78.5.
What it means for you
Progesterone increases SHBG in women with severe PMS in a dose-dependent way. The abstract does not explain whether this leads to symptom relief or whether these doses are practical.
