Intracytoplasmic sperm injection (ICSI) is a specialized form of assisted reproductive technology used to treat infertility. In this procedure, a single sperm is directly injected into an egg, which increases the chances of fertilization. ICSI is often used when there are issues with sperm quality or quantity, making traditional fertilization methods less effective. The process begins with the retrieval of eggs from the female partner, followed by the collection of sperm from the male partner. After the injection, the fertilized egg is monitored for development before being transferred to the uterus, aiming to achieve a successful pregnancy.
