The Truth About Testosterone


“Most of us are familiar with the edict ‘grow some balls’. Women can be its target as much as men, but the phrase itself demonstrates that we associate owning a pair of testicles with being courageous, competitive and aggressive. At the heart of this expression is the belief that simply being male, and particularly having high levels of the hormone testosterone, is responsible for these qualities.”


Dear Claire,
Congratulations on this article! It expresses my opinion on the topic in many ways better than I was ever able to formulate during presentations at conferences. Looking forward to seeing this in print.
Best wishes,
