” There are many other (besides testosterone) behaviour-eliciting hormones fundamental for human well- being, including estrogen and progesterone in females”, Carl Sagan
The question arises about why fibromyalgia is more prevalent in highly sensitive women and men. The debate about nature/nurture has not yielded specific answers and for awhile I have thought of it as a moot point. As a nurse/sociologist I have leaned toward the impact of the social environment in early childhood. But, as some science in human sexuality suggests there is a relationship between levels of testosterone in utero and the extent to which specific traits are manifested after birth. I am now even more confused. However, I continue to believe that both what happens to the development of the fetus and afterwards in the environment are both relevant, although to what degree each plays a more significant role may never be known.
