Evidence-Based Hormone Therapies

Progesterone in Men

In men, progesterone has not been as thoroughly studied as in women. Possible roles are:

  1. Progesterone holds the serum level of estradiol low and may thereby minimize the risk or severity of myocardial infarction, benign prostate hyperplasia, and possibly prostate cancer favored by estradiol excess. Progesterone also keeps dihydrotestosterone (DHT) at a lower level, possibly preventing or attenuating male pattern baldness, favored by DHT excess.
  2. Progesterone is important for the production of aldosterone, cortisol and several androgens
  3. Progesterone keeps aldosterone in balance.
  4. Progesterone has a calming effect on the body.
  5. Progesterone stimulates spermatozoid motility and may be important for male fertility.
