This is a book of readings from the scientific and medical literature on "the contraceptive revolution." It contains the full text of 17 of Egon Diczfalusy's previously published papers with a brief introduction for each. These are presented in chronological sequence, beginning with Reproductive Endocrinology and the Merry Post-War Period (1978) to From Mankind to Humankind: Reproductive Health and Gender Equity (1995). Collectively, these articles provide a unique review of contraceptive science and practice by an eminent reproductive endocrinologist.
