In recent days, a complex and highly sensitive issue has once again occupied the center of the political and social debate in Spain: the participation of trans people in women’s sports categories. The Alliance Against the Erasure of Women, a feminist organization, has submitted a formal request to the central government and the regional executives. Their objective is clear: to achieve a modification in regional trans laws to, as they argue, “protect women’s sports.”
The reader who closely follows global events will know that this is not a new conversation. Organizations of the stature of the International Olympic Committee (IOC) have been analyzing this issue for years without reaching, to date, a position that unifies criteria. Media cases such as those of the weightlifter Laurel Hubbard or the swimmer Lia Thomas have highlighted the difficulty of finding a fair balance that respects the rights of the LGTBIQ+ community and, at the same time, guarantees equity in competition.
The controversy arises from a specific point: the current regional regulations, being based on gender self-determination, allow participation in female categories without an additional biological filter.
Letters to the Government and the Ball in the International Court
The Alliance has moved quickly, sending letters to the Ministry of Education, Vocational Training and Sports, the Higher Sports Council (CSD) and the sports departments of all the autonomies. They have placed particular emphasis on the governments chaired by the Popular Party (PP), urging them to an immediate review, given the harmony they say they perceive with the concerns previously expressed by leaders of this party.
What has been the institutional response? When asked about the possibility of promoting these modifications, the CSD has opted for a position of caution, disassociating itself from direct responsibility. Sources from the Council refer to international organizations and federations, such as the IOC, pointing out that it is “these organizations that establish the rules of participation, in accordance with the characteristics and specificity of each sport.”
Given this response, we ask ourselves: Is it enough to delegate the decision at the international level, or is there political responsibility in the internal regulatory framework?
Biology and Performance: What Does the ‘Scientific Evidence Say?
At the heart of the Alliance’s petition is the warning that trans laws, as drafted, endanger three pillars of sport: the principle of equality, fair play and the safety of athletes. Their central argument is based on the fact that these regulations would be “ignoring scientific evidence” that highlights the significant biological differences between men and women that have a direct impact on sports performance.
The organization’s spokesperson, Lola Venegas, has expressed her concern, indicating that regional laws are “the most explicit when it comes to allowing the presence of self-determined men and women in the female categories.” For the Alliance, action in the autonomous communities must be “immediate”, without undermining its historic request for a broader repeal of gender self-determination.
Institutional Coherence: The Contradiction in Official Documents
Curiously, the debate intersects with a recent official document from the Government itself (PSOE and Sumar): the “Health Guide for Athlete Women“, published by the CSD together with the Ministry of Sports.
The Alliance requires “coherence” between the current legal framework and the findings of this guide, which explicitly recognizes:
- Female biology influences performance, health and injury risk.
- There are physiological and biomechanical differences between men and women that impact sports competition.
For the organization, this official recognition should be translated into public policies that act accordingly. Lola Venegas insists: “Recognizing sexual differences is not discrimination, but a necessary condition to guarantee real equality.” Their fear is that the participation of men in women’s categories will introduce inequalities and, in disciplines where strength or speed are decisive, will “affect the physical integrity of the athletes.”
While the Alliance is pressing for these changes, CSD sources, in their reply to the press, wanted to highlight other actions framed in the same guide that do promote equality in sport: an increase in maternity scholarships, the professionalization of women’s football and a greater presence of women in governing bodies.
The path to sports equity is undoubtedly complex. It requires an objective look at science, active listening to the concerns of all parties, and legislation that is based on justice for all. Will the authorities be able to find the middle point where advances in the rights of the LGTBIQ+ community coexist with the guarantee of fair competition for female athletes?
