Around 70% of IVF treatments fail. Now, groundbreaking images of the earliest stages of pregnancy could help improve the odds. We also look at advances in stem cell research and regenerative therapies.

Around 70% of IVF treatments are unsuccessful. For the first time, researchers have implanted human embryos into an artificial uterine lining, capturing images that provide unprecedented insights into the earliest stages of pregnancy. Their findings could help improve fertility treatments and boost IVF success rates. Once a baby is born, early screening becomes crucial. Just a few drops of blood can help detect serious developmental disorders and prevent long-term complications. We also explore the potential of stem cells, promising new therapeutic approaches, and innovative drug delivery methods that allow medications to be targeted precisely where they are needed most.
