Scientists have successfully created early-stage human embryos using DNA from human skin cells, a breakthrough that could revolutionize fertility treatments and enable same-sex couples to have genetically related children, though the technique requires further refinement before clinical application.
Scientists have successfully created human eggs in the lab using skin cells and a novel technique called 'mitomeiosis,' which could eventually help infertile women and enable gay couples to have genetically related children, though significant ethical and technical challenges remain.
Japan has approved research to create human embryos from stem cells without using ovaries or testes, marking a significant step in in vitro gametogenesis, which could lead to new reproductive technologies and raise ethical questions.
