Headline: Breakthrough in Fertility Research: Scientists Create Early Human Embryos from Skin Cells
Oregon, USA – December 15, 2025 – In a groundbreaking study published in Nature Communications, researchers at Oregon Health & Science University (OHSU) have achieved a significant milestone in fertility research: creating early human embryos from skin cells. The team has developed a novel technique dubbed “mitomeiosis,” combining elements of mitosis and meiosis to produce eggs with a reduced chromosome count, paving the way for potential treatments for infertility.
The current treatments for infertility often come to a grinding halt, especially when the patient has no functional gametes. The only treatment for this instance is donor eggs or sperm. The OHSU team wanted to find a way to create eggs or sperm directly from the patient’s own cells, to make it possible for them to have genetically related children.
The process involves replacing the DNA in donor eggs with DNA from regular skin cells and then using special lab techniques to mimic natural egg formation. While the resulting eggs exhibited chromosomal errors and only a small percentage (9%) reached the crucial blastocyst stage of embryo development, the research demonstrates a “proof of concept” that such an approach is feasible.
“We achieved something that was thought to be impossible,” said Dr. Shoukhrat Mitalipov, director of the OHSU Centre for Embryonic Cell and Gene Therapy, and senior author of the study.
The research offers a potential alternative to donor eggs or sperm, especially for those with no functional gametes. The scientists caution that the technique is far from ready for clinical trials, estimating a timeframe of at least ten years due to remaining challenges in ensuring accurate chromosome separation and addressing potential safety concerns. Multi-generational animal studies would also need to be conducted before clinical use.
If successful, the method could enable older women, cancer survivors, individuals born without functional ovaries, and same-sex couples to have genetically related children. However, ethical and legal considerations surrounding embryo research and the potential for multigenerational effects will need to be addressed.
Despite the hurdles, the OHSU team’s breakthrough represents a major step forward in the field of in-vitro gametogenesis (IVG) and offers a glimmer of hope for millions struggling with infertility worldwide.
