Reading this carefully raises as many questions as it answers -- again, because there's a lot about this that we just don't know yet. Still, it's a good discussion, especially in combination with the page above this one.

Great brief, easy-to-read overview of the scientific evidence. I like that the author addresses the claims made by Dr. Lee by going through any available evidence in the literature. There is still a lot to learn about the role of natural progesterones in the treatment and prevention of certain health conditions (eg. osteoporosis,etc).
