"When the Pill came on the market in 1960, it was enthusiastically embraced by the medical profession and the public. But by the end of the decade, after a crisis over the drug Thalidomide (which was prescribed for morning sickness and caused birth defects) and increasing reports of potential health risks from the Pill, confidence in the drug was ebbing. In 1969 concerns came to a head with the publication of The Doctor's Case Against the Pill."
