This interdisciplinary essay combines science, social sciences, and the humanities to argue in favor of a less rigid understanding of the traditional gender binary of male and female. Relying on recent scientific studies on the sex/gender of the body (internal organs like the brain and chromosomal constitution, for example), this essay mentions results of scientific studies that challenge the binary understanding of gender. These studies point to a much more fluid biological spectrum of the binary male/female—to a trans fluid nature of gender. A less rigid understanding of the nature of gender of all human beings–not just those identified as trans sexual–might help in eradicating prejudices that lead to discrimination and harassment towards the trans community. As the public policy literature reviewed in this article documents, even with laws and policies to protect them from discrimination and harassment, the trans community is still subjected to both. One reason is that laws and policies are still subjected to the interpretation of policy makers and administrators whose decisions, consciously or not, are not immune to biases and prejudices. To further illustrate the scientifically proven trans fluid nature of gender, I will analyze two recent cultural products: One is from Latin America, the Chilean film “Una mujer fatástica,” and the second is an autobiographical essay by a transgender Chicano Professor of Women and Gender Studies—Francisco J. Galarte’s “Transitions: The Dolorous Return of a Chicana/o Transfronterizo.” By analyzing these two cultural products, my aim is to illustrate how these works illustrate gender fluidity in everyday life.

这篇跨学科论文结合了科学、社会科学和人文科学，以支持对传统的男性和女性性别二元论的理解不那么僵化。依靠最近对身体的性别/性别（例如大脑和染色体构成等内部器官）的科学研究，这篇文章提到了挑战性别二元理解的科学研究结果。这些研究指出，男性/女性二元的生物谱更具流动性——性别的跨性流动性质。对所有人的性别本质——而不仅仅是那些被认定为跨性别者——的不那么严格的理解可能有助于消除导致对跨性别社区的歧视和骚扰的偏见。正如本文所回顾的公共政策文献，即使有保护他们免受歧视和骚扰的法律和政策，跨性别社区仍然受到这两种情况的影响。原因之一是，法律和政策仍然受制于决策者和行政人员的解释，他们的决定无论有意与否，都不能免受偏见和偏见的影响。为了进一步说明性别的科学证明的跨性别流动性，我将分析两个最近的文化产品：一个来自拉丁美洲，智利电影“Una mujer fatástica”，第二个是跨性别女性奇卡诺教授的自传性文章和性别研究——弗朗西斯科·J·加拉特 (Francisco J. Galarte) 的“过渡：奇卡纳 (Chicana)/o Transfronterizo 的悲惨回归”。通过分析这两种文化产品，我的目的是说明这些作品如何说明日常生活中的性别流动。
