All post-primary schools in Northern Ireland will be required to teach students about how to get an abortion and how to avoid getting pregnant early.
It happens after Northern Ireland Secretary Chris Heaton-Harris introduced new rules for RSE (relationships and sex education) in Parliament.
He claimed in a written statement that it was his legal responsibility to implement the suggestions made in the UN report.
Until now individuals schools have decided how to teach sex education.
However, the Committee on the Elimination of Discrimination Against Women's (CEDAW) Report recommended that RSE in Northern Ireland be mandatory and thorough.
In practice, this means that students will need to learn about topics like how to avoid getting pregnant, the Northern Ireland legal right to an abortion, and how to access pertinent services.
The Department of Education has been contacted by BBC News NI for a response to the new regulations.
Tuesday, Mr. Heaton-Harris stated, "I have today laid regulations in Parliament to carry out the CEDAW recommendation to'make age-appropriate, comprehensive and scientifically accurate education on sexual and reproductive health and rights, a mandatory component of curriculum for adolescents, covering prevention of early pregnancy and access to abortion in Northern Ireland, and monitor its implementation. '".
"The regulations will mirror the approach taken in England with regard to education about the prevention of early pregnancy and access to abortion.
"I have always preferred that the Department of Education in Northern Ireland update the curriculum as a devolved matter.
"However, despite the fact that the Northern Ireland (Executive Formation) Act 2019 was passed nearly four years ago, adolescents in Northern Ireland are still not receiving an extensive and accurate scientific education about their rights and responsibilities regarding sexual and reproductive health. ".
Currently, the department mandates that every school in Northern Ireland create its own RSE policy and implement RSE curriculum.
However what is actually taught to pupils about RSE has been a matter for each school to decide, based on their school ethos.
That approach has previously been criticised by some experts, who have said it leads to "different and inconsistent learning experiences" for pupils.
In the past, new abortion laws in Northern Ireland were introduced as a result of the Executive Formation Act.
But according to Mr Heaton-Harris, that act also required him to implement recommendations on RSE contained in the CEDAW report.
The CEDAW report said that young people were "denied the education necessary to enjoy their sexual and reproductive health and rights".
In his written statement on Tuesday, Mr Heaton-Harris said he was amending previous education acts in Northern Ireland to make aspects of RSE compulsory.
Although the changes to the RSE curriculum will come into effect from 1 July, the Department of Education must issue guidance to schools by 1 January 2024 on what they are required to teach.
Mr Heaton-Harris said that would give six months for "meaningful engagement with teachers, parents and young people" about the changes.
Furthermore, he stated that parents could still choose to "withdraw their children from education on sexual and reproductive health and rights, or elements of that education.".
"This is in line with the strategy used in England and Scotland," he said.
"Consultation with parents on relationship and sexuality education is already common practice in Northern Ireland and we expect the Department of Education to ensure schools afford parents the opportunity to review relevant materials.
"Educating adolescents on issues such as contraception, and access to abortion in Northern Ireland, should be done in a factual way that does not advocate, or oppose, a particular view on the moral and ethical considerations of abortion or contraception. ".
The changes to RSE have been welcomed by the NSPCC in Northern Ireland.
The new rules were deemed a "positive step" by Natalie Whelehan from the children's charity.
"Making excellent quality RSE teaching available to all secondary school-aged children will ensure they receive information on what constitutes healthy and unhealthy relationships both online and offline and about their right to be safe, heard and protected," she said.
"This positive step also means that young people in Northern Ireland will now have consistent access to similar information available to young people in the rest of the UK. ".
