Intracytoplasmic Sperm Injection (ICSI) is an assisted reproductive technique in which a single sperm is selected and injected directly into the cytoplasm of a mature egg using a fine glass needle. It is the treatment of choice for male factor infertility, including low sperm count, poor motility, or previous IVF fertilisation failure.
