Crocodile Sperm Proteome


ABSTRACT: In a reproductive strategy that is considered unique to the mammalian lineage, spermatozoa must undergo a series of physiological changes, termed capacitation, in the female reproductive tract prior to developing their capacity to fertilize an ovum. Here, we have employed a comparative proteomic strategy to explore the biological significance of this form of post-testicular maturation in the ancient reptilian species of the Australian saltwater crocodile (Crocodylus porosus).

Competition to achieve paternity has contributed to the development of a multitude of elaborate male reproductive strategies. In one of the most well-studied examples, the spermatozoa of all mammalian species must undergo a series of physiological changes, termed capacitation, in the female reproductive tract before realizing their potential to fertilize an ovum. However, the evolutionary origin and adaptive advantage afforded by capacitation remains obscure. Here, we report the use of comparati  ...[more]
