Only 13% of rapes reported to the gardaí result in a prosecution.
According to the Central Statistics Office, 786 rapes were reported to the gardaí in 2018.
The following year, 811 were recorded on the Garda PULSE system.
New figures, released to Newstalk under the Freedom of Information Act, reveal the number of prosecutions for rape taken in those years.
The Director of Public Prosecutions says there were 108 in 2018, and 107 last year.
Rape survivor Debbie Cole says the numbers are very low.
She observed: "I feel that the DPP have let a lot of survivors down by not bringing cases that, for the public, would seem as an open and closed case.
"If it manages to get to a court situation, there are so many judges that are not getting the impact that this has on a survivor... so they just hand down very small sentences."
Separate figures from the DPP show 33 people were prosecuted for murder last year - the same as in 2018.
