Protests have prevented the showing of Adult Human Female for a second time.
The decision to cancel the screening of the film, which has been branded transphobic by critics, led to fresh concerns being raised about freedom of speech.
We have taken a closer look at what the furore is all about.
What is Adult Human Female? It is a controversial film which claims to be the first documentary to look at "the clash between women's rights and trans ideology".The 92-minute feature was directed by independent film-makers Deirdre O'Neill and Mike Wayne.It contains criticism of the "trans movement", which is accused of "capturing" major institutions such as universities and political parties, while manufacturing confusion around sex and gender.Opponents say it is a “one-sided and inflammatory depiction of trans people”.
Why is Edinburgh University embroiled in the row? Screenings of the film have become flashpoints in the bitter culture war between different sides in the debate about gender identity.In December, a planned showing of Adult Human Female in Edinburgh had to be cancelled due to safety concerns after protesters formed a blockade.
The showing was rearranged for Wednesday this week, but had to be cancelled again after a similar protest.
