Piezo-assisted intra-cytoplasmic sperm injection: A comparative study of two penetration techniques

Abstract:

This paper discusses the application of piezoactuator in intra-cytoplasmic sperm injection (ICSI). Specifically, it presents a comparative study of two techniques in the penetration of oocyte (egg cell) : linear-reciprocating and partially-rotating techniques. The other conditions during penetration, including media preparation, installation, and controller, are maintained the same during the operation. The experiment shows that piezo-assisted ICSI achieves better results compared to manual ICSI even when mercury is not used (as is usually the case). Furthermore, partially-rotating technique causes less vibration to the oocyte compared to linear-reciprocating technique. © 2007 IEEE.
