A monkey has given birth to a healthy baby created from an egg taken from transplanted ovarian tissue, in a breakthrough scientists say could lead to new fertility treatment for women with cancer. The baby, named Brenda, is the first primate born using an egg taken not from a working ovary but from parts of the ovary implanted elsewhere in the mother’s body. This tissue contains cells that can develop into eggs, without needing a full ovary. The egg was then removed, fertilized and the embryo was transplanted into a surrogate mother. “This breakthrough may be a major step in preserving fertility for young cancer survivors,” said David Lee, a fertility expert at Oregon Health & Science University (OHSU) in Portland, who worked on the primate project.
