Beaumont Hospital has denied that a video showing a man and woman taking part in sexual activities was filmed at their hospital.
The explicit footage appears to have been filmed in a toilet, and shows a man recording the acts on his phone.
A photo has accompanied the videos which shows a group picture of nurses and doctors in a hospital environment, Dublin Live reports.
The caption underneath these pictures circles the two people involved in the footage and states that the doctor is "married" and that both parties work at "Beaumont Hospital".
In a statement, a spokeswoman for the hospital has categorically stated that the people involved are not in any way related to Beaumont.

She said: "Beaumont Hospital understands that images and video material has been circulated online that purports to show staff from the hospital behaving in an inappropriate manner.
"This material did not originate in Beaumont. Beaumont Hospital management states categorically and emphatically that the individuals depicted are not in any way connected with the organisation, now or at any point in the past."
She concluded: "It is regrettable that this material has been linked with Beaumont Hospital, causing unnecessary concern for patients, families and staff."
