Students are being urged to get themselves tested for S.T.I's.
The call comes from the Union of Students in Ireland, as part of its "Shag Week" campaign.
The yearly initiative aims to raise awareness about sexual health and safety.
Deputy USI president Annie Hoey says getting tested is vital for people who are sexually active.
Ms. Hoey says: "We're really encouraging people to go out and to get tested".
She added that HIV Ireland is offering free testing in their offices on Eccles Street on Wednesday from 1.30pm-3.30pm.
