Sperm washing is the process in which individual sperms are separated from the seminal fluid. The sperms are then used in intrauterine insemination (IUI) or in vitro fertilization (IVF).
Sperm washing is a standard procedure used in infertility treatment.
Sperm may be "washed" by density gradient centrifugation or by a "direct swim-up" technique that doesn't involve centrifugation. In normal semen samples, centrifugation causes no more DNA damage to spermatozoa than a direct swim-up technique.

Famous quotes containing the word washing:
“...you don’t have to be as good as white people, you have to be better or the best. When Negroes are average, they fail, unless they are very, very lucky. Now, if you’re average and white, honey, you can go far. Just look at Dan Quayle. If that boy was colored he’d be washing dishes somewhere.”
—Annie Elizabeth Delany (b. 1891)
