Some people might use online sperm donation because the cost of accessing donor sperm at fertility clinics is too high in Australia.
However, online sperm donors may provide people with unscreened sperm that might be carrying sexually transmitted infections or inheritable genetic conditions.
People looking for a sperm donor can go to a fertility clinic, ask a friend to donate or look for a donor online, including on an app or via social media.
This is despite donors initially agreeing to provide sperm for home insemination (using a syringe to inject the donor sperm into the vagina).
People might be placed at risk when they agree to meet a potential online sperm donor in person.
