Speaker: Professor Brett Nixon, Priority Research Centre for Reproductive Science, School of Environmental and Life Sciences, Faculty of Science, University of Newcastle, Australia.

It is well recognised that the spermatozoa of all mammalian species only acquire functional maturity as they are conveyed through the male (epididymal maturation) and female (capacitation) reproductive tracts.

However, despite decades of research we still do not fully understand the evolutionary origin or the adaptive advantage that is afforded by such elaborate forms of post-testicular sperm maturation.

These remain as among the most perplexing questions in gamete biology, particularly as the balance of evidence suggests that post-testicular maturation may not be essential to achieve fertilisation in other vertebrate species.

In this seminar, Professor Brett Nixon will discuss how he has exploited recent advances in proteomics and functional profiling tools to reassess the nature and extent of post-testicular sperm maturation that occurs in comparative models of birds, reptiles and mammals.
