Intra Cytoplasmic Sperm Injection (ICSI) is used to treat male infertility and is a procedure added to IVF when there is not enough sperm available for the IVF procedure.
In normal IVF many sperm are put together with an egg in the hopes that one of these will enter and fertilize the egg. With ICSI, a single sperm is injected directly into an egg.
Why is ICSI done?
ICSI is used in cases of male infertility. This includes a very low sperm count, abnormally shaped sperm, and poor sperm movement where they cannot penetrate the egg, surgical removal from a testicle through a small incision and if regular IVF treatment cycles have not achieved fertilization.
What is the procedure for ICSI?
ICSI is done as part of IVF and is done in the IVF lab. As with regular IVF, you will take medications to stimulate egg growth, while your doctor will monitor your progress with blood tests.
Mature eggs will be collected using a specialized ultrasound guided needle. Your partner will provide his sperm sample the same day. The embryologist will chose the best available single sperm cell and inject it directly into the egg using a highly advanced micromanipulation microscope.
If successful fertilization takes place, an embryo or two will be transferred to your uterus, three to five days after retrieval. This is done using a thin flexible catheter that is inserted into the cervix.
What can I expect after treatment?
In vitro fertilization (IVF) related injections, monitoring and the procedures are physically and emotionally demanding on woman. Your doctor will probably advise you to avoid strenuous exercise for the rest
Used with eggs of good quality and once fertilization takes place, the success rate for a couple using ICSI with IVF is the same as a couple doing regular IVF treatment.
