Intracytoplasmic Sperm Injection (ICSI)
ICSI is used to assist fertilization.
In Vitro Fertilization (IVF) involves placing several thousand sperm and eggs together in a culture dish and allowing the sperm to fertilize the eggs. The dishes are kept in an incubator overnight and examined under a microscope the next following morning for signs of fertilization. Normal sperm parameters on a semen analysis predict a fertilization rate of 65-70% for most patients. For patients with abnormalities on semen analysis, intracytoplasmic sperm injection (ICSI) is used to assist fertilization.
