Over 200 people, many belonging to the transgender community in Ireland, marched towards Leinster House this afternoon calling for better healthcare services for people who are seeking gender reassignment treatment.
Organisers, who are not aligned with any organisation or political party, said that current services are "unacceptable" and are falling behind other countries in the developed world.
They are calling on the HSE to engage with a model of "informed consent".
At present, anyone seeking gender reassignment treatment must receive a medical diagnosis. However, many transgender people want to see an end to this practice.
They are also calling for treatment to be handled by general practitioners.
It is estimated that 45,000 people in Ireland identify as transgender, although not all will seek gender reassignment treatment.
Organisers of the protest also handed in a list of demands to The Department of the Taoiseach.
