ICSI (Intracytoplasmic Sperm Injection) and IMSI (Intracytoplasmic Morphologically Selected Sperm Injection) are two techniques used in in vitro fertilization (IVF) to address infertility, particularly male factor infertility.ICSI is a standard procedure where a single sperm is directly injected into the egg to facilitate fertilization.IMSI is a more advanced technique that uses a high-magnification microscope (up to 6000x) to select sperm with the best morphology before injection into the egg, potentially improving the chances of successful fertilization and embryo development.
