MORN2 regulates the morphology and energy metabolism of mitochondria and is required for male fertility in mice

Summary

Researchers identified a protein called MORN2 that plays a critical role in shaping mitochondria and supporting their energy production in sperm cells. When this protein was absent in mice, the animals became infertile due to defective mitochondrial structures in their sperm. The study adds to our understanding of the molecular requirements for male reproductive health.
