On September 25, 2025, Slovakia’s National Council passed a historic constitutional amendment defining gender strictly as male or female. The measure, approved with 90 votes in favor, 7 against, and 2 abstentions, is being hailed by supporters as a defense of traditional values and a reaffirmation of biological reality in law.
The amendment declares that “the mother is a woman and the father is a man,” explicitly enshrining a biological definition of gender into Slovakia’s constitution. It also bans surrogacy, affirms a child’s right to know his or her biological parents, and guarantees that men and women must receive equal pay for the same work. In addition, the law strengthens parental rights over their children’s education, limiting outside interference in moral and cultural upbringing.
Lawmakers backing the amendment argued that these changes were necessary to preserve Slovakia’s cultural identity and resist external pressures to adopt more radical gender and family policies. By setting clear definitions and protecting parental authority, the country is shielding future generations from ideological experiments imposed by international institutions.
The move was strongly supported by the Christian Democratic Movement (KDH) and the Christian Union, which first advanced the proposal earlier this year. Their coalition emphasized that the amendment aligns with Slovakia’s Christian heritage and reflects the will of the majority of citizens who value family, faith, and tradition.
With this decision, Slovakia becomes one of the few European nations to constitutionally define gender in biological terms and ban surrogacy outright. The amendment is both a strong stand for national sovereignty and for the truth of biological gender.
