Intracystoplasmic Sperm Injection (ICSI)
Intracytoplasmic sperm injection, known as ICSI, is a relatively new technique where a specially designed glass needle (micropipette) is used to inject a single sperm into a single egg. Originally, ICSI was used in cases of severe male factor infertility, where fertilization could not occur on its own. Over the past few years, however, its indication has expanded to include cases where there are a limited number of eggs, a history of failed fertilization and following sperm or oocyte cryopereservation. At CFG, our embryologists are experts in the micromanipulation required to successfully perform ICSI. This is evident in our outstanding fertilization rates. Below is a microphotographic (magnified 300X) depiction of the ICSI procedure.
ICSI is one of many tools your reproductive endocrinologist can utilize to help you become pregnant. Like any procedure however, the indications need to be considered and risks/ benefits weighed. At CFG we are confident in the safety and utility of this procedure, but we also believe that it should only be used in appropriate circumstances rather than the convenience of the laboratory or doctors. Please speak with your doctor to see if ICSI is indicated for you.
