The purpose of this article is to understand the possible gender biases that may guide the modus operandi of the Inter-American Human Rights System (IASR) in cases of torture and ill-treatment in prisons. Through the different search mechaminsms of the IACHR, 183 decisions were collected, obtained from a set of keywords. Their analysis allows us to observe that gender discussions in the ISHR began in the 1990s and, since then, relatively generic debates have prevailed on the subject. The IACHR develops a somewhat more in-depth debate on gender in cases of sexual violence committed against women prisoners. The other types of violations appear to be common to men and women, characterized and classified contextually. Furthermore, the perpetrators of violence are not necessarily individualized, nor are the measures imposed by the State generally of a collective nature. Although these aspects softens certain criticisms proposed by the literature on torture and international human rights systems, some actions carried out by the IAHRS seem to have more reformist effects in relation to gender discrimination.
