Gregory had to find someone willing to take on a controversial project and is eligible to provide the study of volunteers for the trial. Pincus found a doctor that worked 40 miles from Shrawsbury, Massachusetts, lab. Pincus had been given a synthetic version of the hormone to rabbits and rabbits to inhibit ovulation. Rock, Pincus's partner was giving women the same hormone to enable them to become pregnant. Rock placed these patients on a daily regimen for several months. After stopping the treatment he hoped that the reproductive organs would rebound and enable his patients to conceive. After administrating 80 patients, 13 of them were conceived.
