In the early 1950s the Puerto Rican women were used for experimentation in the making of the first birth control pill. The Pill was invented by Dr. Gregory Goodwin Pincus but strict laws in the U.S. didn’t permit full scale experimentation. In 1955 Dr. Pincus and his colleague, Harvard obstetrician and gynecologist Dr. John Rock visited Puerto Rico and then decided it was a perfect place to test out their pill due to the lack of anti-birth control laws.
The trials began in Rio Piedras but quickly moved throughout the poor sectors in the island. The experiments was based on poor and working class women; these women were not told the pill was experimental and were not told the negative effects the pill could have on them. Three young women died during these experiments and no investigations were conducted to determine cause of death.
