Intracytoplasmic Sperm Injection (ICSI)

Intracytoplasmic sperm injection (ICSI) is an in vitro fertilization procedure in which a single sperm is injected directly into an egg.

ICSI is used to treat sperm-related infertility problems. The procedure is used to enhance the fertilization phase of in vitro fertilization (IVF) by injecting a single sperm into a mature egg. The fertilized egg is then placed in a woman's uterus or fallopian tube.
