ICSI stands for Intracytoplasmic Sperm Injection. It is a technique used in assisted reproductive technology (ART) to help couples concieve.

During ICSI, a single sperm is injected directly into an egg using a microscopic
needle. This is done in a laboratory setting by a trained specialist called
embryologist. The fertilized egg (embryo)is grown in the lab for 3-5 days and is then implanted into the uterus of the female partner, where it has a chance to develop into a pregnancy. Both fresh and frozen embryo transfer are done based on the patient and embryo parameters.

ICSI is often used when there are problems with the male partner's sperm, such as low sperm count, poor sperm motility, or abnormal sperm shape. It is also done in cases of unexplained infertility,endometriosis,low ovarian reserve,failed IUI’s.By injecting a single healthy sperm directly into the egg, ICSI can increase the chances of fertilization and a successful pregnancy.
