The Citizen's Assembly is to hear from six women directly affected by abortion this afternoon.
Today's Dublin meeting is the fourth in a series of sessions looking at the future of the Eighth Amendment.
Assembly members have been warned the content is likely to be "moving and emotionally challenging".
As proceedings began, Chairperson Ms Justice Mary Laffoy said the Assembly's work on the issue was entering a new phase. She also moved to thank those who contributed personal testimony.
"I would like to sincerely thank each woman who has shared her experience. I think it is an essential aspect of our considerations," she said.
The Assembly will also meet tomorrow. The personal stories of the six women interviewed are to be made available to the public and can be accessed online here: https://www.citizensassembly.ie/en/
