Women's participation in STEM is increasing worldwide. Nevertheless, these disciplines continue to be considered predominantly masculine, and women represent less than 30% of researchers. In Uruguay, women's participation in research is nearly equal to men's. However, there's a markedly reduced presence of women in decision-making positions. Despite this, systematic studies on gender involvement in the Latin American academic community are still scarce. In-depth analysis, aimed at understanding the factors affecting the career development of women in STEM are much needed to identify actions that might correct these trends. We report the results of the implementation at the Institut Pasteur of Montevideo of a public policy tool for equality: the Model for Quality with Gender Equity, developed by the Ministry of Social Development of Uruguay. In its first stage, the model requires an in-depth institutional diagnosis to establish a baseline to help design actions to promote gender mainstreaming in the institution's human resource management. In this document in Spanish, we report the results of this diagnostic, evidencing some gender inequities. For example, even though women represent 55% of the Institute's population, the data show a higher number of them in positions with contracts for fewer than 40 hours per week and suggest stagnation at the master's training level. Importantly, we found an average wage gap of 26% regardless of age, academic rank, or training. This is one of the first studies of self-diagnosis focused on gender in a scientific institution in Latin American countries. This diagnostic report reflects a widespread institutional will to progress towards a more equitable work environment. We expect to establish a precedent for its application in other scientific institutions as an auditable tool in creating potential public policies for equality in Science. Resumen: La participación de las mujeres en STEM ha aumentado en los últimos años en todo el mundo. Sin embargo, estas disciplinas continúan considerándose principalmente masculinas, y las mujeres representan menos del 30% de los investigadores. En Uruguay, las mujeres tienen una alta participación en la investigación, aunque con representación minoritaria en los ámbitos de toma de decisiones. Los estudios sistemáticos sobre la participación de género en la comunidad académica aún son escasos, y los análisis exhaustivos de los factores que afectan la trayectoria de las mujeres en STEM s...
