Two women who starred on Married at First Sight UK claim they were sexually assaulted on the show by their husbands, a BBC Panorama investigation claims.
Another MAFS bride has alleged that she was also a victim of sexual misconduct by an on-screen spouse while filming the Channel 4 hit.
The three women, who have not been named, have raised serious concerns about the welfare and safety of female participants on the TV experiment, which has also become a huge hit in the US and Australia.
The men accused of sex attacks deny all the allegations against them set to be broadcast in the documentary: The Dark Side of Married at First Sight, which will be shown tonight at 8pm on BBC One.
The Panorama investigation will claim that the makers of the show, where couples marry after meeting for the first time on their wedding day, have left vulnerable participants at risk of harm.
In a statement, Channel 4 said: ‘We have not seen the programme and will comment when we know more.’
In nine seasons of MAFS UK, only five married couples remain together out of 70-plus who have taken part over the past 11 years.

The show began in Denmark in 2013 and has since been sold to broadcasters in 28 nations, including the US in 2014 and the UK in 2015.
MAFS UK’s experts are Paul Carrick Brunson, Charlene Douglas and Mel Schilling, who died tragically in March aged just 53.
BBC Panorama presenter Noor Nanji claims to have spoken to three female contestants on the British version of the hit show who who have accused their on-screen husbands of sexual misconduct.
None of those couples are said to be together.
Two women have made the bombshell claim that they were victims of crimes, in the form of sexual assaults.
Married at First Sight pushes hopeful single participants to their limits, forcing them to marry and move in with a complete stranger on the basis of science.
They do not meet until their wedding days – and get to know one another after saying ‘I do’.
Those brave enough to take a shot at true love are asked to give up their apartments, personal space and the single status to forge a new life with their match.
Makers of the show insist a lot of careful research goes into the matchmaking process.
Psychologists are involved before men and women take part and prenuptial agreements are built into the show’s fabric to avoid financial loss of any kind.
Married at First Sight also pays some costs associated with divorces within a certain time period.
Hardly any couples who take part remain together. In the UK version of MAFS, the marriage success rate is around five to seven per cent.
