Hormones and sexual behaviour.
Despite new technological advances and improved assay methods, the relationship between hormones and human sexual behavior is still poorly understood. Sex drive and responsiveness, gender identification, and sexual preference are all influenced by hormones. Endocrine studies of impotent men have produced conflicting results. Exogenous androgens seem to produce some results with impotent men....
متن کاملLayered sexual selection: a comparative analysis of sexual behaviour within an assemblage of piophilid flies
Although many theoretical and empirical studies have addressed the dynamics of sexual selection, little is known about the evolution of multiple sexual-selection mechanisms within the same system. I performed a qualitative comparative study of sexual behaviours in seven sympatric species of piophilid flies to identify and compare the apparent mechanisms of sexual selection operating in each sys...
متن کاملSexual behaviour: Secrets and flies
Recent studies of Drosophila courtship mutants provide a molecular foundation for sexual orientation and behaviour.
متن کاملSexual selection and speciation.
The power of sexual selection to drive changes in mate recognition traits gives it the potential to be a potent force in speciation. Much of the evidence to support this possibility comes from comparative studies that examine differences in the number of species between clades that apparently differ in the intensity of sexual selection. We argue that more detailed studies are needed, examining ...
متن کاملSexual behaviour: Courting dissatisfaction
A nuclear receptor, the product of the dissatisfaction gene, has been found to regulate Drosophila sexual behaviour, probably via its action in a small subset of neurons. The results shed new light on the genetic determination of sexual behaviour.
