More than 100 medical abortions have been carried out in Northern Ireland since new laws came into force earlier this year.
A total of 129 terminations took place here between March 31 and May 22.
The figure was revealed by Health Minister Robin Swann after an Assembly question from DUP MLA Paul Givan.
It comes as the Assembly prepares to debate abortion regulations today in a motion tabled by Mr Givan, which he says will "send a message" to politicians at Westminster that we did not endorse the new abortion rules.
New legislation was passed at Westminster last October and regulations giving the new laws effect were introduced on March 31.
They provide for terminations on request for the first 12 weeks of pregnancy, and up to 24 weeks where there is a risk of injury to the physical or mental health of the pregnant woman.
Abortion is also available in cases of severe and fatal foetal abnormalities with no gestational limit, as well as for conditions such as Down's syndrome.
Under the new regulations a notification of termination must be sent to Chief Medical Officer Dr Michael McBride within 14 days of an abortion.
According to the Department of Health, 129 notifications had been received up to May 22.
Previously only a handful of abortions took place every year here.
Eight abortions were carried out in local hospitals during 2018/19, four less than the previous year.
Mr Givan said: "Abortion regulations were imposed on Northern Ireland without consultation and they are some of the most liberal laws in Europe, allowing for abortion until birth for babies diagnosed with a disability.
"These figures show a significant increase in the number of abortions taking place in Northern Ireland."
Disability campaigner Heidi Crowter (24), who was born with Down's syndrome, has written to all MLAs outlining how offensive the regulations imposed by Westminster are to people with disabilities.
The DUP motion "welcomes the important intervention of disability campaigner Heidi Crowter and rejects the imposition of abortion legislation which extends to all non-fatal disabilities, including Down's syndrome".
Mr Givan added: "The DUP is a pro-life party and we want to see the most vulnerable in our society protected.
"MLAs have an opportunity today to send a clear message to Westminster that we do not accept these ill-conceived, discriminatory and extreme abortion regulations."
Deputy First Minister Michelle O'Neill said Sinn Fein had submitted an amended motion as her party "does not support the specific provision in the Westminster legislation which goes beyond fatal foetal abnormalities to include non-fatal disabilities including Down's syndrome".
Grainne Teggart, Amnesty International's Northern Ireland campaigns manager, urged MLAs to reject the DUP motion, which she says seeks to restrict abortion rights here.
"This motion will change nothing legally but is a clear signal that the DUP wants to roll back the hard-won rights of women and girls," she said.
"Sinn Fein and other parties must not prop up a dangerous anti-choice agenda. Instead, they should support human rights and show they're on the side of women. Women and girls are being failed and forgotten, left without vital abortion services despite regulations coming into force two months ago."
Ms Teggart added: "The priority right now should be women's safety and wellbeing.
"The Department of Health must urgently commission services and ensure they are accessible to all who need them.
"This is where MLAs should be focusing their attention."
Catholic bishops urged MLAs to oppose the new Westminster regulations, describing them as "an unjust law, which was imposed without the consent of the people of Northern Ireland".
In a letter, the bishops called on politicians "to take steps to formulate new regulations that will reflect more fully the will of a significant majority of the people in this jurisdiction to protect the lives of mothers and their unborn children".
