Judith Butler's work in "Gender Trouble" explores the complexities of sex and gender, suggesting that the traditional understanding of sex as a fixed biological category is in fact culturally constructed. She argues that if the idea of immutable sex is challenged, it raises the question of whether 'sex' is not inherently tied to gender dynamics, blurring the line between the two concepts.

This perspective implies that what we consider sex may actually be a product of gender constructions. By proposing that sex and gender are intricately linked or possibly indistinguishable, Butler invites a re-examination of identity and the societal norms that shape our understanding of both sex and gender.
