What Countries Recognize a Third Gender?
The topic of this week’s TestTube Plus is sex and gender. Trace began this series by explaining the terms involved in gender and sexuality. In this episode, Trace explains the science of gender identity. Future episodes will be discussing how sexuality and gender express themselves in non-human animals, and what a post-gender society might look like.

But things don’t alway develop properly: sometimes both a fetus can get both male and female characteristics — these are known as hermaphrodites or intersex.
Some animals are gynandromorphs: they have both male and female cells.
TestTube Plus is built for enthusiastic science fans seeking out comprehensive conversations on the geeky topics they love. Each week host Trace Dominguez probes deep to unearth the details, latest developments, and opinions on topics like aliens, genetics, and artificial intelligence.
