A technique where the mother's DNA is removed from her egg and then placed inside a donor egg from another woman is called maternal spindle transfer. The egg is then fertilized and evolves into an embryo and is then transferred for pregnancy. A woman who had many failed cycles of IVF was able to give birth to a healthy baby boy, with this technique. According to Dr. Jonathon Tilly, mitochondria plays a key role with the development of embryos and fertilization. An abundance of data gathered suggests that people who have an infertility/ poor egg and embryo condition have mitochondrial dysfunction or deficiency.
I think this is a very interesting topic, many times infertility is blamed on other things such as birth control (which have no proven side affects of this), but a mitochondrial dysfunction/ deficiency makes sense. I also think it is great that there have been successful cases with the spindle transfer technique. I hope this can help many women in the future who have trouble with infertility and seek to have children.
