Motile sperm are difficult to collect with a conventional cell sorter because they are vulnerable to physical damage. A research collaboration between Kumamoto and Kyoto Universities in Japan has developed a technique that uses a cell sorter with microfluidic chip technology to reduce cell damage and improve in vitro fertilization (IVF) rates.
This research may increase IVF rates to improve production of experimental animals and livestock, and could be used as a fertility treatment in human reproductive medicine.
It is important to select fertile sperm with good motility to obtain high IVF rates.
“We expect that our research can be used to increase the success rate of IVF in animals, and for fertility treatments in human reproductive medicine,” the researchers said.
