Developed in parallel to sperm and semen problems, sperm washing techniques aim at achieving normal sperm for intra uterine insemination. Unprocessed sperms are not used for insemination. If ejaculate is directly injected into the uterus, it can result in allergic reactions, severe pain and infection due to non-sperm content.
Washing process is based on separation of unnecessary cells for fertilization from ejaculate. Ejaculate is not a sterile sample since it might contain anaerobic and aerobic bacteria. Cellular debris from vas deferens, prostate gland, seminal vesicle, and urethra might also be contained in the ejaculate. Any of these cells are separated from ejaculate by washing process.
