This lecture will consider different patterns of male and female sexual behaviours, how hormones act to control them, and how and why the rigid link between sex and reproduction has been relaxed during evolution to include maintenance of social relationships. We will also consider whether other animals have problems with impotence and if diversity in sexual orientation is unique to humans.
