What is intracytoplasmic sperm injection (ICSI)?

Intracytoplasmic sperm injection (ICSI) is an infertility treatment. It includes injecting live or motile sperm directly into collected eggs in a laboratory. This manner can create an embryo (fertilized egg). ICSI is a form of in vitro fertilization (IVF). Healthcare providers most typically use ICSI while male infertility affects a person’s ability to conceive a child.
