An episode of the ITV2 show which aired on June 30 is being looked at following a grand total of... eight complaints by viewers, around 0.0006% of the show's 1.3 million viewers.
The show is the one in which Terry Walsh and Emma-Jane Woodham had sex on top of a bed in the villa, prompting shock from the other Islanders and viewers alike.
A spokesperson for Ofcom told DS: "This programme included sexual material shortly after the watershed.
"We're investigating whether the transition to more adult content was unduly abrupt."
Following the episode airing, ITV defended the scenes earlier this month.
While some viewers compared the shots to 'soft porn', an ITV insider told The Sun newspaper at the time: "The focus on what was shown was the reaction of the islanders rather than what Emma and Terry were doing."
A spokesperson for the channel insisted that the shots were "inexplicit".
In all, Love Island accumulated a total of 39 official complaints to Ofcom during its series this year, which proved a ratings hit for ITV2.
The channel has already confirmed a third run of the show for next summer.
