Scientists have created human eggs in the lab using a similar process to the one used to clone the famous Dolly the sheep, then used in vitro fertilization (IVF) to turn them into embryos. Although ...

Mature egg cells, or oocytes, are essential for fertilization in assisted reproductive technologies. However, some 'denuded' oocytes, or those lacking the protective granulosa cell layer, fail to ...

Scientists have created egg-like cells capable of fertilization using DNA from ordinary skin cells in what could be a major breakthrough for infertility research. Using a newly developed technique to ...

Scientists have created baby mice with two fathers for the first time by turning male mouse stem cells into female cells in a ...

Creating human eggs from adult cells just got one step closer to reality. A technique used in cloning combined with fertilization and a bit of chemical coaxing caused human skin cells to produce eggs ...

A human female is born with all the egg cells she will ever have. The possibility for the development of new oocytes is zero. Given this constraint, it is crucial that these gametes remain healthy and ...
