'The new podcast The Retrievals hears from a dozen women who had the same procedure at the Yale Fertility Center and who all reported extreme pain throughout. At the time they were told by staff they had been given the maximum amount of pain relief, meaning they couldn’t have more. However, it later transpired that a nurse at the clinic had been stealing fentanyl and replacing it with saline solution. It is thought that 200 patients had been denied pain relief during egg retrievals over a period of five months.'
