Regular Sperm Wash
Sperm processing, or washing, is usually performed to prepare a fresh semen sample for IUI (Intrauterine Insemination) or other ART (Assisted Reproductive Technology) procedures.  Sperm washing achieves two very important goals. First, it removes most of the seminal plasma from the semen that would otherwise not react well if directly inseminated into the uterus. Second, it concentrates the sperm density into a small volume that is suitable for intrauterine insemination. In some cases, sperm washing may also enhance the forward progression of the sperm or the percent motility.  The Regular Wash is the standard wash that is usually sufficient for most patients samples. A Complete Semen Analysis is performed on the specimen before the wash process begins. The sample is then carefully mixed with a washing media, centrifuged and remixed with washing media, and concentrated down to a volume suitable for IUI. A post-wash semen analysis is then performed to determine the final outcome of the procedure and to calculate the total number of motile sperm in the IUI prep, which is now ready for insemination.  Specimens prepared for IUI may be easily transported if kept between room and body temperature and delivered within one hour of final preparation. This conveniently allows patients to have the semen washed at one facility then taken to another physician for the IUI procedure. A wash may also be ordered a trial or test run as a check to see how the sample will be enhanced and its suitability as an IUI prep.
