Gregory Pincus, Min-Chueh Chang, and John Rock were hired by Margaret Sanger and Katharine McCormick to develop the birth control pill.

Welcome to the fifth installment of our series chronicling the history of the birth control pill. In the previous installment, Margaret Sanger and Katharine McCormick envisioned and bankrolled the development of the birth control pill. Now it had to be tested in large-scale trials.

John Rock, Gregory Pincus, and Min-Chueh Chang had collaborated in the Pill’s development; now it was time to conduct clinical trials. The first study observed 60 women, some of whom were infertility patients while others were nurses. These small trials involved daily temperature readings, vaginal smears, and urine samples, as well as monthly endometrial biopsies. Although the initial results seemed promising, the sample size was small and few of the subjects complied with the protocol.

The approval of the Pill in 1960 marked a turning point in our history.

More test subjects were needed. At this point, historians’ accounts differ. Elaine Tyler May claims that, unable to locate an acceptable pool of volunteers, the researchers tested the Pill on subjects who could not give their consent, such as psychiatric patients. According to Bernard Asbell, however, Rock was scrupulous when it came to informed consent, despite it not being a legal requirement — or even much of a concept at all at this time in history.

Willing participants notwithstanding, conducting such trials in the United States posed a challenge, due to laws against contraception. So the first large-scale clinical trials were conducted in Puerto Rico in 1956. Puerto Rico was densely populated and there was a high demand for alternatives to permanent sterilization, which was widespread on the island due to funding from a wealthy eugenicist named Clarence Gamble, who advocated sterilization for the world’s poor. The clinical trials in Puerto Rico were conducted by Drs. Edris Rice-Wray and Adaline Sattherthwaite; the brand of birth control pill tested was named Enovid. Volunteers were so easy to come by that some clinics had waiting lists. Continue reading →

Welcome to the fourth installment of our series chronicling the history of the birth control pill. In the previous installment, progesterone, the birth control pill’s active ingredient, could only be administered intravenously. Scientists working in Mexico figured out how to alter its chemical structure so that progesterone would be active when taken orally.

Katharine McCormick was born into a moneyed family and was, in 1904, the second female graduated by the Massachusetts Institute of Technology. After receiving her degree in biology, she married a wealthy man, but shortly into the marriage she gained control of her husband’s estate due to his illness. She put a lot of this money to good use: In the 1920s, she aided Margaret Sanger’s efforts to smuggle diaphragms into the country.

Katharine McCormick, a philanthropist and one of the first scientifically trained women, provided early funding for the Pill.

Her involvement with Sanger didn’t end there; indeed, both Sanger and McCormick had a lot in common, despite Sanger’s working-class childhood and McCormick’s privileged upbringing. According to historian Elaine Tyler May, McCormick and Sanger both had “a tremendous faith in the possibility of science,” and Sanger “believed that science held the key to contraception and to women’s emancipation.” Back in the ’20s, Sanger wrote:

Science must make woman the owner, the mistress of herself. Science, the only possible savior of mankind, must put it in the power of woman to decide for herself whether she will or will not become a mother.

In 1950, McCormick again joined forces with Sanger. In the mid-’40s, after a countrywide tour of family-planning clinics, Sanger had come to the conclusion that the diaphragm was not an adequate form of birth control, revitalizing her hope for a “magic pill.” Neither pharmaceutical companies nor the government wanted to invest in contraceptive research, considering it a “disreputable” area of study, so Sanger hatched a scheme to bankroll the independent development of an oral contraceptive. At Sanger’s behest, McCormick provided the lion’s share of funding for the project — more than $2 million (compared to the value of a dollar in the year 2000, that would be about the equivalent of $12 million). Sanger and McCormick tapped Gregory Pincus to conduct the research. McCormick, thanks to her education in biology, oversaw the research in addition to funding it. Continue reading →
