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.
