Mechanisms involved

James V. Kohl   (31 July 2007)  Stone Independent Research email

Several citations from my database attest to the likelihood of a mechanism involving DHEA metabolism that may explain the association between smoking and menopause. Either the reduction in estrogen, or the increased production of androgens (and their metabolites) is indicated below. It would be interesting to learn more about any mechanism the authors are proposing.
