Louise Brown was the first baby born through in vitro fertilization (IVF) in 1978. While her birth led to optimism that IVF could help infertile couples, it also raised ethical debates around IVF and stem cell research that involve the creation and destruction of human embryos. Today, over 400,000 frozen embryos exist in limbo and there are ongoing discussions around their moral status and use in research. Regulations have been lacking due to the political controversy around issues connected to abortion. Overall, IVF remains both ethically complex but also seen as "pro-life" by many since it enables parenthood, ensuring the debates continue.
