South Korean posts falsely claim infertility test can 'reveal woman's sexual history' - Yahoo News

An article circulating on Facebook in South Korea claims a type of infertility test can reveal how many sexual partners a woman has had. But medical experts told AFP there is currently no test that can show how many sexual partners a person has had. They said the infertility test cited in the posts -- which detects the presence of anti-sperm antibodies inside a person -- can only be used to investigate the causes of infertility.

"The test that shows you have many men your girlfriend slept with," reads a Korean-language Facebook post shared on September 4.

The post links to an article on tabloid news site Adsensima about a man whose wife allegedly took an anti-sperm antibody test after struggling to get pregnant.

Anti-sperm antibodies (ASAs) are proteins that mistakenly identify sperm as harmful invaders and attempt to eliminate them.

They are more common in men -- usually caused by testicular injury -- but can also occur in women, although it is not clear why.

The article quotes the unidentified man as saying: "The doctor said there were 14 types of anti-sperm antibodies in her body. When I asked what that meant, they said each type of antibody corresponded to a different sperm."

The article says the man searched for the infertility test online and found it shows "how many men a woman has had sex with and for how long".

"In short, it's a test that can destroy a family," the article adds.
