Auckland neuroscientist Dr Angelo Tedoldi travelled around to find out about the role of genes in sexuality to answer why people are gay, straight or bisexual. "Why am I gay?" is a question he's asked himself, and in a new documentary he talks to academics, and takes a scientific test himself. The answer is complicated and fluid. Dr Tedoldi's Why Am I Gay? screens on TVNZ1 this Tuesday night (November 8).
