What is ICSI - intracytoplasmic sperm injection?

Intracytoplasmic sperm injection (ICSI) is a very effective IVF technique for treating male infertility.

Intracytoplasmic means "into the cytoplasm" - the part of a cell that is inside the cell membrane.

  • In an egg there is an outer shell, called the zona pellucida, and under that the oolemma or cell membrane (see picture below).
  • Sperm are immobilized and picked up using a very small and sharp needle - and then injected into the cytoplasm of the egg.
  • In many IVF programs intracytoplasmic sperm injection results in fertilization of about 70% to 80% of the eggs injected with sperm.
