ICSI (Intracytoplasmic Sperm Injection)
ICSI is a method of treating infertility that is close to IVF. It is different just as the method of fertilization between eggs and sperm that process from the scientists only. ICSI comes from the full word, Intracytoplasmic Sperm Injection, which means that the sperm is selected for mixing one by one (1 sperm per 1 egg). The scientist will inject sperm directly into the egg. The embryo will be cultured for about 2-6 days and be transferred into the uterus later on.
From a patient perspective, undergoing an ICSI treatment cycle is exactly the same as a conventional IVF cycle, and the same steps are involved, except for the part of the fertilization process after the ovum and sperm come into the laboratory procedure
IVF: The embryologist will allow the strongest sperm to fertilize the egg itself like natural
ICSI: The embryologist will inject sperm directly into the egg for fertilization.
