A critical enzyme for sperm formation could be a target for treating male infertility

The activity of the Skp1 protein is crucial for sperm formation, Penn Vet scientists found. In a dividing sperm precursor cell, chromosomes (in purple) normally align in the middle, as shown on the left. But in cells lacking Skp1, as shown on the right, chromosomes fail to align and are instead distributed chaotically around the cell. (Image: Courtesy of the Wang laboratory)
