ICSI is a specialized form of IVF where a single sperm is injected directly into a mature egg using a fine glass needle. It is used when sperm quality or quantity is insufficient for conventional IVF, or after previous IVF fertilization failure.
ICSI is now used in roughly 60-70% of all IVF cycles globally, even when male factor is not present — though many clinics reserve it for specific indications.
