Columbia University researchers have deployed their STAR AI system, originally derived from astrophysics algorithms, to detect 44 viable sperm cells in samples previously deemed sterile by human embryologists. The AI processed 8 million images in under an hour, spotting cells missed by technicians after two days of manual examination. Notably, three sperm identified by STAR successfully fertilized an egg, resulting in a pregnancy due this December, marking a significant advancement in male infertility treatment technologies.
