INTRA CYTOPLASMIC SPERM INJECTION
Olympus ICSI Microscope
Intra-cytoplasmic sperm injection (ICSI) is a procedure consisting of injection of a single sperm directly into an egg in order to fertilize it. This fertilized egg (embryo) is then transferred to the uterus of the expecting mother. The procedure for ICSI is similar to that for IVF. Intra-cytoplasmic sperm injection (ICSI) differs from conventional in vitro fertilisation (IVF) in that the embryologist selects a single sperm to be injected directly into an egg, instead of fertilisation taking place in a dish where many sperm are placed near an egg.
Process of ICSI
- The male partner is asked to produce a sperm sample or one is surgically extracted from him.
- The eggs are surgically extracted from the female partner also.
- The sperm is injected into the egg with the help of a small hollow needle.
- The fertilized egg is now kept under observation and its development is tracked systematically.
- Once it is assured that the embryo is showing all signs of normal growth , the embryo is implanted into the uterus and allowed to mature and grow
Both fresh sperms and frozen sperms may be used for the process. The process happens using a method called micromanipulation. This uses a special tool along with specialized equipment to pick up a single sperm and directly inject it into the egg. A cycle of ICSI treatment takes from four to six weeks. In the first case the couple has to spend a day at the clinic for egg and sperm retrieval procedures.
