Intracytoplasmic Sperm Injection (ICSI) is a specialized form of assisted reproductive technology (ART) used to treat male infertility. During ICSI, a single sperm is directly injected into an egg to facilitate fertilization. This technique is often employed when traditional in vitro fertilization (IVF) methods are unsuccessful or when male infertility factors, such as low sperm count or poor sperm motility, are present.
