Skin‑cell eggs enable IVG embryos

OHSU scientists removed a skin cell’s nucleus, placed it in a donor egg, induced a 'mitomeiosis' step to discard half the chromosomes, and then fertilized it with sperm. They produced 82 functional eggs and early embryos up to six days, though success was ~9% and chromosome selection was error‑prone with no crossing‑over. The method hints at future infertility treatments and same‑sex reproduction but is far from clinical use. — This pushes urgent debates on parentage law, embryo research limits, and regulation of in‑vitro gametogenesis as a route to human reproduction.
