A Utah startup, aided by Mayo Clinic, says it has grown mature sperm from spermatogonial stem cells in the lab and used them to generate preliminary human embryos for safety testing, signaling a potential fertility breakthrough, but the findings haven’t been peer‑reviewed yet and costs could be a barrier.
Utah-based Paterna Biosciences says it has found a way to coax sperm-forming stem cells from testicular tissue to become mature, functional sperm in a lab and used this sperm to create embryos; the work has not yet been peer-reviewed or independently verified, and the company plans larger studies to compare lab-made and natural sperm in men with infertility before attempting pregnancies; if validated, the approach could offer a biological option for some infertile men, but questions of cost and safety remain.
