Sperm washing

Sperm washing is a procedure used to prepare sperm for use in Intrauterine insemination (IUI) or In vitro fertilisation (IVF) which removes chemicals from the semen, which may cause adverse reactions in the uterus. The process also concentrates the sperm into a small volume, increasing the chance of conception during IUI and IVF.

Procedure

The sperm washing procedure involves a number of steps. First, the semen is collected from the male partner or a donor. This is usually done through masturbation, but can also be collected during sexual intercourse using a special condom. The semen is then placed in a test tube and centrifuged. This separates the sperm from the seminal fluid, which can cause reactions in the uterus that make pregnancy more difficult. The sperm is then washed in a solution to remove any remaining seminal fluid and other unwanted substances. The washed sperm is then used in IUI or IVF procedures.

Uses

Sperm washing is used in a variety of fertility treatments, including IUI and IVF. It is also used in cases where the male partner is HIV positive, to reduce the risk of transmitting the virus to the woman and the baby. In these cases, the sperm washing procedure is combined with other methods to further reduce the risk of HIV transmission.

Risks and complications

While sperm washing is generally safe, there are some risks and complications associated with the procedure. These include damage to the sperm, which can reduce fertility, and the potential for contamination of the sperm sample. However, these risks are generally low and the procedure is considered safe for most men.
