This transformative guide completely breaks down our current understanding of biological sex and gender diversity.

Introducing readers to seven variations of human sex, commonly considered intersex, the book challenges the myth that sex and gender are binary and explores the inherent

diversity of biological sex and its relationship to gender identity and expression, and the impact this has on society. Examining historical, linguistic and socio-cultural

understandings of sex and gender, as well as genetic and scientific definitions, the book is an important resource for dismantling gender and sexuality-based discrimination and

promoting understanding and inclusivity.


Co-written by one of the world's leading intersex activists and a highly respected scholar in biological sciences, and accompanied with detailed anatomical illustrations throughout,

this pioneering text is the essential introduction to gender and sex diversity for gender studies, women's studies, biology and genetics courses, as well as professionals working

with intersex and trans communities.

Which Came First, the Chicken or the Egg: Sex and Gender; 8. Sex and Gender Terms: Linguistic Collateral Damage; References

Spectrum of Sex uniquely presents an intersex perspective on sex/gender diversity. The book clearly reviews the biology underlying intersex expression and features brief essays from intersex persons themselves, offering a forum for the intersex community to speak forth with their own voice.

Hida Viloria is a renowned intersex human rights activist, the founding director of the Intersex Campaign for Equality, and author of the Lambda Literary Award nominated, Born Both: An Intersex Life (Hachette US).

Maria Nieto is a Professor in the Department of Biological Sciences at California State University, East Bay. Maria's research interests focus on sex and gender diversity and she has given keynotes and presentations to a range of audiences.
