by Betty Kamen
“Betty Kamen’s book is easy-to-read and highly informative on every aspect of the subject of female functioning and hormones. Her conversational style and the many illustrations made this scientific book read like a novel! Highly recommended – whether you’re having menstrual problems or are menopausal. progesterone is actually the hormone that needs supplementation.” – A reader from New York City, April 16, 1998.
