Creating Eggs and Sperm from Stem Cells: The Next Big Thing in Assisted Reproduction?

June 5, 2019

(STAT News) – Until recently, the only way to make eggs or sperm was the old-fashioned way: in the ovaries and testes. In the not-too-distant future, it may be possible to use cells from almost any part of the body to create these germ cells, also known as gametes. This process, called in vitro gametogenesis (IVG), raises the possibility that babies could be made using muscle or liver or blood cells. While not yet ready for prospective human parents — so far it has only been accomplished successfully in mice — it raises major ethical and legal questions that we should start thinking and talking about now.
