What is sperm washing?

Sperm washing is a process in which sperm is separated from semen to remove any potential contaminants, such as bacteria and viruses. This technique is commonly used in assisted reproductive technologies, including intrauterine insemination (IUI) and in vitro fertilization (IVF), to increase the chances of a successful pregnancy.

During sperm washing, the sperm sample is placed in a special medium and centrifuged to isolate the sperm from the other components of the semen. The washed sperm is then used for insemination procedures, either directly into the uterus (IUI) or in combination with eggs in a laboratory setting (IVF).

Sperm washing is particularly important for couples where the male partner has a sexually transmitted infection (STI) or HIV, as it helps to reduce the risk of transmitting the infection to the female partner or potential offspring. It is also used in cases where the male partner has low sperm count, poor sperm motility, or abnormal sperm morphology, as it can help to select the healthiest and most viable sperm for fertilization.

Overall, sperm washing is a safe and effective technique that can improve the chances of conception in couples undergoing fertility treatments. It is typically performed by trained professionals in specialized fertility clinics.
