High DNA integrity sperm selection using surface acoustic waves

Author affiliations

Abstract

Male infertility is a global reproductive issue, several clinical approaches have been developed to tackle it, but their effectiveness is limited by the labour-intensive and time-consuming sperm selection procedures used. Here, we present an automated, acoustic based continuous-flow method capable of selecting high quality sperm with considerably improved motility and DNA integrity compared to the initial raw bull semen. The acoustic field translates larger sperm and guides highly motile sperm across the channel width. The result is the selection of sperm with over 50% and 60% improvement in vitality and progressive motility and more than 38% improvement in DNA integrity, respectively, while providing a clinically relevant volume and selected sperm number for the performance of in vitro fertilisation (IVF) and intracytoplasmic sperm injection (ICSI) by selecting over 60 000 sperm in under an hour.
