WPI and Stanford researchers develop sperm-sorting device that could improve IVF success

(Worcester Polytechnic Institute) Women undergoing in vitro fertilization (IVF) may become pregnant with fewer treatment cycles, thanks to a new device developed by a team of researchers from Worcester Polytechnic Institute (WPI) and Stanford University that uses an 'obstacle course' to sort and select faster and healthier sperm cells for use in IVF treatment. The work, funded by two separate but collaborative grants from the National Science Foundation, was published in the most recent issue of Advanced Science.
