Wrong embryo implanted at Milan hospital, patient underwent unplanned procedure

A woman underwent an unplanned endometrial aspiration after receiving another couple's cryopreserved embryo by mistake at Milan's San Raffaele hospital, according to Italian newspaper la Repubblica. The incident occurred in late July at the hospital's Medically Assisted Reproduction center. Milan's Health Protection Agency (ATS) moved to suspend the facility's Embryology Laboratory for fifteen days after inspections, one jointly conducted with Italy's Ministry of Health, identified non-conformities. 🔹 What happened: Two patients were waiting to be called. The sequencing was reversed — the first patient was called second — and the embryo transfer was carried out on the wrong woman. Staff identified the error within eight minutes. The affected patient was informed twenty-four hours later and consented to endometrial aspiration to avoid a pregnancy with a biologically unrelated embryo. The couple whose embryo had been used was not notified immediately; the facility cited concern for their emotional wellbeing. By the end of the same day, that couple received a transfer of a second, correct embryo, which succeeded. The hospital described the cause as 'human error.' 🔹 Why it matters: For the woman who received the wrong embryo, the error translated into a physical intervention on her body that she had not planned for. Her consent came twenty-four hours after the mistake, once the alternative already carried emotional and physical weight. The second couple spent hours without knowing what had happened to their embryo. Assisted reproduction is an emotionally intensive process, and the institutional response — deferring notification to manage stress — shifted the institution's comfort above those patients' right to information. The fifteen-day suspension also affects other couples currently in treatment at the laboratory. 📌 EPM Take: The label 'human error' functions here as a closing statement, not an explanation. It names no process, assigns no responsibility, and proposes no remedy visible in public statements. The patient who consented to endometrial aspiration did so under conditions where declining carried a different emotional cost than it would have before the error occurred — that distinction matters for any serious discussion of informed consent in assisted reproduction settings. The couple whose embryo was transferred to a stranger was not told immediately: someone in that institution made a judgment call about their right to know. That decision deserves scrutiny beyond the fifteen-day suspension. EPM has covered Italy's exclusion of 31,000 medical students from training this year. Workforce gaps create pressure points across the health system — and waiting room sequencing errors are precisely where that pressure surfaces first.
