Full Definition
ICSI (Intracytoplasmic Sperm Injection) is an advanced assisted reproductive technique used primarily for male factor infertility. The procedure involves the direct injection of a single sperm into the cytoplasm of a mature egg using a microscopic needle. ICSI bypasses the natural fertilization process and is indicated when sperm counts are very low, sperm motility is poor, or previous IVF attempts have resulted in failed fertilization. The technique has revolutionized treatment for severe male infertility and is now routinely used in many IVF programs.
Usage
