Is male infertility partly a simple fluid mechanics problem?
Physicist Erkan Tuzel works in a field that seems just about as far removed as possible from delicate questions about human reproduction; his lab at Worcester Polytechnic Institute develops algorithms to describe the behavior of complex fluids. But after he heard a talk by Harvard Medical School bioengineer Utkan Demirci, who carves microscopically small channels and then allows fluids to flow through them, the two began to talk about collaborating. Their common ground? Designing technology that could cull the healthiest, fastest-moving sperm from the slowpokes.
