Pronunciation: ICK-see
Also written as: ICSI — Intracytoplasmic Sperm Injection
Intracytoplasmic Sperm Injection - a specialized IVF technique where a single sperm is directly injected into an egg.
Full Definition
Intracytoplasmic Sperm Injection is an advanced assisted reproductive technique used when male factor infertility is present or when conventional IVF has failed. A single healthy sperm is selected and injected directly into the cytoplasm of a mature egg using a microscopic needle. This bypasses natural barriers that might prevent fertilization. ICSI is particularly useful for men with very low sperm counts, poor sperm motility, or abnormal sperm morphology. The technique has revolutionized treatment for severe male factor infertility.
