Sperm washing is performed on semen samples that will be used for Intrauterine Insemination (IUI), In Vitro Fertilization (IVF) or IVF with Intracytoplasmic Sperm Injection (ICSI). The sperm washing process facilitates the segregation of motile sperm from immotile sperm, dead sperm and seminal fluid.
Sperm washing can remove dead sperm and those sperm with poor motility. This leaves behind sperm that can swim faster and that are more likely to fertilize your egg. Sperm washing can also get rid of the white blood cells, mucous and seminal fluid surrounding the sperm, which can also interfere with fertility.
Sperm washing is the process of separating individual sperm from semen. This process of sperm preparation is intended to mimic the natural process that occurs when healthy sperm separate from other elements in the ejaculate as they actively move through the cervical mucus and towards the fallopian tubes during spontaneous conception.
