Breakthrough: Human Eggs From Skin Cells Transform IVF Potential

10/2/2025

Summary

Story summary

Oregon Health and Science University researchers created fertilizable human eggs from skin cells, potentially transforming in vitro fertilization (IVF) for infertile couples.
The study yielded 82 immature eggs, with fewer than 10% reaching the blastocyst stage.
All embryos were chromosomally abnormal, raising viability concerns.
The technique, somatic cell nuclear transfer, mimics natural egg formation but needs further safety, efficacy research and governance.
