Dozens of women came to a clinic at Yale for fertility treatment. All of them experienced unexpected and severe pain during a procedure called the egg retrieval. They said that their pain was not taken seriously by their health care providers, or that they were not believed. As a consequence, they came up with their own explanations for their pain. Often they blamed themselves.

In the months that followed, it was discovered that a nurse at the clinic had been stealing fentanyl used in patient procedures and replacing it with saline. Now the patients who were in pain had an explanation for it — and lots of questions for the institution that let this happen.
