Intra-Cytoplasmic Sperm Injection (ICSI) is a technique where the egg is fertilized outside the body by injecting the sperm directly into it. Usually, very few sperm are required. The embryo(s) are then transferred back into the woman’s uterus.
This technique is extremely useful when the male partner produces low-quality, low-count sperm. In above to this, the ability of the sperm to penetrate the egg is not a concern since penetration is bypassed. Therefore, this technique is used for men with abnormal semen parameters, older couples and for those with failed IVF attempts.
