STARTUP CLAIMS IT SUCCESSFULLY GREW HUMAN SPERM IN A DISH FOR THE FIRST TIME TO HELP INFERTILE MEN

Summary from the TLDR newsletter

Utah-based startup Paterna Biosciences claims it has successfully grown functional human sperm in a dish. The startup says it has even used these engineered cells to create visibly healthy-looking embryos. Paterna's team extracted sperm-making stem cells, placed them in a lab dish, and used computer models to calculate the exact chemical signals the cells needed to thrive. The procedure aims to recreate a healthy environment in the lab, then use the cultured mature sperm for fertilization.
