Researchers from the University of Pittsburgh School of Medicine (right in our neighborhood!) published some findings this week that may mean great things for those who suffer from male infertility. The researchers used human induced pluripotent stem cells (hiPSCs)from skin samples (unbelievable to think that a skin graft in the future could make a man fertile again!) to create precursor sperm cells.

Looking forward to hearing more about this in the future.
