League of Legends coach Tony Chau has sparked a controversial debate by sharing statistics from 147 ranked games to suggest that tracking his duo partner yuulu’s menstrual cycle could enhance their win rate. According to a report by Esports Insider, Chau claimed that yuulu’s win rate decreased from 57.5% outside of menstruation to 52% during it, presenting this as a strategy for optimization rather than intrusion.
While the numbers provide some insight, the crux of the matter lies in how esports repeatedly finds itself entangled in discussions about women’s bodies in the context of competitive performance limitations. This has significant implications for player well-being, trust, and the overall inclusivity of the esports community.
Understanding the Research
On the surface, Chau’s post may appear as a small-scale performance experiment involving a sample of solo queue games, a tracked variable, and an attempt to draw a connection between physiology and outcomes. However, in reality, it represents a flimsy dataset centered around a deeply personal subject. Reportedly, yuulu only discovered later that Chau had been maintaining a CRM to track her menstrual cycle for months.
This approach stands in stark contrast to the type of welfare research that the esports industry truly requires. While existing studies on player health have focused on issues like stress, burnout, sleep, physical strain, and support systems, there is a noticeable absence of in-depth research specifically addressing female players’ needs.
This doesn’t mean that hormonal health should be off-limits as a topic. Rather, it emphasizes the importance of obtaining consent, providing context, and conducting scientifically rigorous investigations, especially in an industry that still lacks sufficient research focused on female players.
The Ongoing Concern
This incident resonates negatively within the League of Legends esports community due to its echoes of past controversies. In September 2025, FlyQuest top laner Bwipo faced suspension after suggesting on a stream that menstruation hinders women’s ability to compete at a high level. Such instances further complicate the already challenging conversations surrounding women’s participation in esports.
This pattern mirrors similar narratives of exclusion and discrimination prevalent across the esports landscape. By framing women’s performance as a problem that requires explanation rather than as players deserving support, these discussions perpetuate harmful stereotypes and hinder progress towards creating more inclusive and sustainable pathways for women in competitive gaming.
Even when presented in a light-hearted manner, such rhetoric inadvertently provides justification for those seeking to use biology as a barrier to entry. Once this door is opened, language intended for player welfare can swiftly transform into exclusionary rhetoric.
The Industry’s Response
While the esports industry has made strides in addressing issues like burnout, practice intensity, and mental health, it still grapples with handling gender-specific welfare concerns effectively. While there is a growing emphasis on diversity, equal opportunities, and structural support in recent discussions, the industry continues to rely on impulsive public statements rather than informed, player-centric policies.
This incident underscores the need for esports organizations to prioritize player welfare as integral to performance. Rather than amateurishly tracking bodily functions for engagement, the focus should shift towards implementing robust support systems, maintaining privacy standards, and conducting evidence-based research that players can trust.
For now, the immediate fallout from this controversy shines a spotlight on the problematic ways in which women’s participation in esports is discussed. The real challenge ahead lies in distinguishing genuine welfare science from outdated stereotypes masquerading as competitive insights.
