Scientists from the United States and the United Kingdom have revealed, in a first-of-its-kind study, that they were able to grow human eggs in a lab. Their achievement could someday lead to new fertility treatments.
The eggs were developed from an early stage in ovarian tissue to a mature stage in which they could have been ready for fertilization. However, the eggs appeared to have many abnormalities. More research needs to be done before the technique behind these lab-grown eggs could be used to help women facing certain fertility concerns. "When we really examine these eggs, we could tell that there were a lot of things wrong with them, but by knowing what's wrong with them, then that allows us to go back and refine the technology. Hopefully, as this work continues, we will see some of these abnormalities disappear in terms of the quality of the eggs that we get," David Albertini, co-author of the study and director of the Division of Laboratories at the Center for Human Reproduction in New York. cnn
