"A breakthrough was announced last week in the world of fertility science. Scientists took skin cells from a human and used them to make egg cells. Yes, you read that right: skin made an egg. They then fertilised the egg with sperm by IVF and took it to the stage where it could be implanted into a womb."
"And although they didn't take the experiment that far they are optimistic the resulting fertilised egg could develop into a baby in a surrogate mother."
Skin cells from a human were reprogrammed into functional egg cells. Those eggs were fertilised with sperm through in vitro fertilisation and cultured to a developmental stage suitable for uterine implantation. The experiment did not proceed to transferring embryos into a surrogate, but the team expressed optimism that a fertilised egg could develop into a baby in a surrogate mother. The method could potentially create eggs for same-sex couples and people with infertility, offering a pathway to genetic parenthood without donor gametes or traditional egg retrieval.
