ABSTRACT

Intracytoplasmic sperm injection (ICSI) has emerged as a pivotal technique in the management of male factor infertility. One of the critical steps of ICSI is the immobilization of sperm prior to injection into the oocyte, which is essential for ensuring precision and optimizing fertilization. This review provides a detailed examination of current sperm immobilization methods, including traditional manual techniques, and LASER technology. The implications of these techniques on fertilization rates, embryo quality, and overall clinical outcomes are discussed. Furthermore, potential risks associated with each method are evaluated, highlighting the necessity for additional data, continued research, and addressing the current gaps in evidence.
