Intracytoplasmic Sperm Injection (ICSI)
This 3D medical animation shows intracytoplasmic sperm injection, a part of the in vitro fertilization procedure used to treat infertility. During this procedure, a needle picks up a single sperm. An egg is held in place with a pipette while the sperm is injected directly into the egg, passing through the zona pellucida, perivitelline space, egg membrane, and into the egg's cytoplasm.
