Thousands of people marched in Paris today to call for the repeal of the Taubira law which legalised same-sex marriage.
Marchers also protested against the use of assisted reproduction techniques and surrogate mothers to enable same-sex couples to have children.
Police estimated the crowd at 24,000, while organisers gave a figure of 200,000.
The demonstration was organised by ManifporTous, an organisation made up of private citizens who oppose marriage equality.
The group have been quiet for the last two years, but organised the protest to put pressure on president hopefuls just 6 months before the elections.
Protestors gathered at the western edge of Paris at the Porte de Dauphine and walked to Place du Trocadero in the centre of the capital.
Organisers claimed that people from all over the country flocked to take part in the march.
Protestors reportedly carried signs which read “in 2017, I will vote for the family” and “women’s wombs are not for sale.”
It is unlikely the law will be revisited by any of the candidates running in the election, however Jean-Frédéric Poisson of the Christian Democratic Party may consider repealing the law if the movement gains more traction.
None of the candidates attended the march but François Fillon, who is in favour of amending the law to prevent same sex couples from adopting children, sent a message of support to the demonstrators.
