Many people are reporting that taking sesamin is killing their sex drive? Does anyone have any information on this phenomenon??? Sesamin is a lignan. Lignans have similar action to phytoestrogens in that it acts as a week estrogen and may occupy the estrogen receptor site if enough is present to vastly outnumber hormonal estrogen? But these studies, mainly on breast cancer prevention, have found that this action is present in estrogen receptor sites on breast tissue. May this action lower estrogen in men (such as soy isoflavone)? And may it lower estrogen to a point where it casues this disruption in libido? I would appreciate any feedback.
