Assessing sperm motility using acoustic plate mode devices

In this work we report a simple time of flight technique for assessing the number and motility of pig sperm in a semen sample. Acoustic plate mode (APM) devices have been employed as the sensor element at the end of a channel down which sperm swim. Combining the APM data with conventional microscopy, an estimate of 18.9 plusmn4.8 pg for the pig sperm effective mass at 52 MHz APM devices is derived.
