摘　　要：Three kinds of microinsemination techniques are prevailing all over the world in recent years, i.e. (ⅰ) partial zona dissection (PZD); (ⅱ) subzonal insemination (SUZI), and (ⅲ) intracytoplasmic sperm injection (ICSI). The common aim of the above techniques is to compensate for the failure or low success of in vitro fertilization and they are effectively used in the human clinics. The success rate of SUZI and ICSI is higher than that of PZD at present. As to the underlying mechanism, most studies were conducted to analyze the physiological effects and success rate or the importance of sperm acrosome reaction,
