Ep 3. Are There More Than Two Sexes?

In the seventh season of the science documentary series "Through the Wormhole," the third episode is titled "Are There More Than Two Sexes?" The episode delves into the concept of biological sex and gender by examining emerging scientific evidence and cultural beliefs.

The episode opens with a question about the traditional binary system of gender identification, which has long categorized individuals as either male or female based on their biological sex organs. With more understanding of sex and gender as separate constructs, researchers begin to investigate whether biological differences exist among humans beyond these two categories. They explore the emergence of a spectrum of gender identities that challenge traditional social constructs and leading scientific institutions to rethink traditional gender norms.

The episode examines the biological aspects of sex, such as chromosomes and gonads, to discover their potential influence on gender identity. It features pioneering researchers who are studying the variety of biological indicators that subtlely signify sex. The researchers also reveal how these findings can expand our understanding since these indicators, when taken together, create a range of phenotypic traits that can confound traditional binary coding of sexuality.

The cultural implications of gender identity are explored in the episode as well. The show highlights how societal norms policing masculinity and femininity impact those who don't fit within these zones, which has led to negative outcomes, such as discrimination, bias, and violence.

The episode examines communities that are embracing and promoting gender diversity. With one in every two thousand children being born with intersex genitalia, some advocates for more inclusive terms have been making progress worldwide. Intersex individuals present a unique opportunity to verify the multiple natural forms of human sex that go beyond typical male-female binary norms. The program discusses how intersex and nonbinary individuals have navigated cultural and medical interventions. It also provides insights from physicians in the field who support personalized medical interventions to allow intersex individuals the chance to control decisions about their bodies.

Through scientific investigation and cultural research, "Through the Wormhole: Are There More Than Two Sexes?" is a thought-provoking episode that pushes the envelope of our understanding of sex, gender and biological identity. By exploring various human experiences and scientific discoveries, it highlights our potential biases and provides a new viewpoint into an issue that has long remained a source of political, cultural, and personal debate. The show equips viewers with the knowledge and tools they need to critically evaluate our historical assumptions about gender roles, sexes and potentially complex identities.
