What Is Intracytoplasmic Sperm Injection?
By Chioma Umeha Intracytoplasmic sperm injection is commonly referred as – ICSI. It is a simple way of saying “inject sperm into egg.” ICSI is a very effective method to fertilize eggs in the invitro-fertilisation (IVF) lab after they have been aspirated from the female. Its main use is for significant male infertility cases. IVF with ICSI involves the use of specialized micromanipulation tools and equipment and inverted microscopes that enable embryologists to select and pick up individual sperm in a specially designed ICSI needle. The needle is carefully advanced through the outer shell of the egg and the egg membrane – and the sperm is injected into the inner part (cytoplasm) of the egg. This usually results in normal fertilization in about 75 to 85 per cent of eggs injected with sperm. However, first the woman must be stimulated with medications and have an egg retrieval procedure so we can obtain several eggs for in vitro fertilization and ICSI.
