Q: What is Intracytoplasmic Sperm Injection (ICSI)?
A: Intracytoplasmic Sperm Injection ICSI is a medical procedure done to improve a woman's chances getting pregnant. ICSI is used for many etiologies (causes) of infertility — typically for "male factor infertility." It is specifically helpful when there are not enough sperm available for fertilization.
ICSI is a procedure added to IVF, in-vitro fertilization when there is not enough sperm available for the IVF procedure.
- First, an egg is obtained from the ovary by inserting a needle into a follicle.
- One sperm is then taken from the ejaculate and picked up with a fine, glass needle.
- A mature egg is then held with a specialized holding pipette.
- In a technique called 'micromanipulation,' the tip of the fine glass needle is then inserted through the outside of the egg (zona) and into the inside (cytoplasm) of the egg.
- The sperm is then injected into the inside of the egg.
- The egg is then placed into an incubation solution and checked the next day for evidence of fertilization.
