A high powered microscope is used to pick out and the best sperm cells which are then used in a traditional ICSI protocol. In ICSI a magnification of x400 is used, while in IMSI an amplification of x6000 to x10,000 is used, increasing the magnification by a factor of 15. This allows the sperm to be examined in greater detail, including the nucleus which contains the sperm's genetic material. The use of this method has resulted in higher pregnancy and delivery rates and lower abortion rates.[citation needed] IMSI is a method that can be chosen by for anyone who has failed IVF cycles in the past, and for couples who have a component of male infertility.[citation needed]
