Only 13% of rapes reported to the gardai result in prosecution.
According to the CSO, 786 rapes were reported to the gardai in 2018.
The following year, 811 were recorded on the Garda Pulse system.
New figures, released 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 "I feel that the DPP has let a lot of survivors down by not bringing cases that for the publci would seem like 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 this has on a survivor, so they just hand down very small sentences."
CEO of the Dublin Rape Crisis Centre Noeline Blackwell says “We get a lot more people disclosing rape and sexual assault to us because we run the national 24-hour helpline so we know there is a lot more than that".
“The reasons people drop off are varied. Some people drop off the system because they get tired and worn out by the process. Some people are afraid of the process and there is no doubt that it is one of the most vicious trial processes going.
