    Pregnancy has a positive effect on MS patients, especially during the 3rd trimester.  Rebound of MS increases in the postpartum period.  Estriol is the dominant pregnancy estrogen.  Progesterone is also produced at high levels.  The withdrawal of these hormones in the postpartum period are likely to lead to this rebound in MS.

thyroid deiodinase T3 T4 hormone hormones

shared by Nathan Goodyear on 24 Nov 14 - No Cached
  • From a broad perspective, this paradigm can be seen as an example of how hormones are activated or inactivated in a controlled fashion in specific extraglandular tissues, in an analogous role to 5α-reductase and P450 aromatase in sex steroid metabolism and to 11β-hydroxysteroid dehydrogenase in glucocorticoid metabolism.

    It is always important to work out the biochemical mechanism of action.  Study finds Siberian Rhubarbs mechanism of action is through activation ER-beta receptors.  No activity/affinity for ER-alpha found in this study.  This is important as the ER-beta provides an anti-inflammatory, antigrowth signal.

    Licorice root extract, also known as glycyrrhizic acid, found to quickly reduce endogenous Testosterone production in women.  The proposed mechanism is via inhibition of 17-hydroxysteroid dehydrogenase and 17-20 Lyase.  This is a good adjuvant in the treatment of PCOS.

    Statin and combined Ezetimibe-statin therapy reduce Testosterone levels in men--though combination therapy reduced LH and Testosterone levels less than high dose statin therapy, but it still did reduce Testosterone.  This is so counterproductive and reveals much of the thought behind cholesterol.  Low T in men is associated with all CVD.
