The last 30 years has seen an explosion of research into the biological basis of male homosexuality.
Historically, much research focused on the effects of upbringing and childrearing on the development of an individual's sexual orientation. More recent research, however, has focused on areas such as molecular genetics, neuroanatomy and endocrinology in a bid to fine out what makes someone gay.
This talk will review research findings on this area, and discuss the ethical implications of such findings. Dr Mark Sergeant is a lecturer in Psychology at Nottingham Trent University.
His PhD studies focused on the evolution of male homosexuality. He has lectured extensively on the topic and is an active research in the field of sexual science
