Whether a woman is using ICI, IUI, or doing home insemination with frozen sperm, she must order either unwashed or washed sperm from a bank.

Washed or unwashed sperm
"Washed" means the sperm is separated from semen. Most experts recommend using washed sperm. Unwashed sperm (sperm not separated from semen) placed into the uterus can cause a bad reaction, including nausea and vomiting.
Amy Erickson-Hagen, director of Cryogenic Laboratories offered this explanation:
ICI (Standard) Preparation -- A cryoprotectant is added to the raw semen prior to freezing. The specimen is considered ready for intra-cervical insemination (ICI) or can be further processed at your clinic for intrauterine insemination (IUI) or in vitro fertilization (IVF).
IUI (Pre-Washed) Preparation: The seminal plasma (liquid portion) of the semen specimens is removed by washing and centrifugation and replaced with a biological buffer. A cryoprotectant is added to the washed semen specimen prior to freezing. The specimen is considered ready for use in an intrauterine insemination (IUI) or can be further processed at your clinic for in vitro fertilization (IVF).
