  The results suggest that in rodents sperm cooperation is more widespread than assumed so far and highlight the importance of diploid versus haploid selection in the evolution of sperm design and function.
  Sperm motility in the fat-tailed dunnart was retained for up to six days when cooled to 4 degrees C, suggesting that sperm from this species have some degree of tolerance to cold shock, although after this time, however, the percentage of motile spermatozoa and their motility rating declined.
  Egg maturation and fertilization in marsupials.
  Whether there are fundamental differences between the two major extant infraclasses of mammals, marsupials and eutherians, in some of the processes associated with fertilization is conjectural at the present time.
  It is concluded that, as the hook‐shaped sperm head and long sperm tail occur across the muroid subfamilies, as well as in the heteromyid rodents, it is likely to be the ancestral condition within each of the subfam families with the various forms of nonhooked sperm heads, that are sometimes associated with short tails, being highly derived states.

  The secretory activity of cells in the isthmus of the oviduct may relate more to the production of the shell membrane that comes to surround the zygote than to the cells performing a nutritive or protective function for the spermatozoa during their period of storage within the female reproductive tract.
  Regulated storage and subsequent transformation of spermatozoa in the fallopian tubes of an Australian marsupial, Sminthopsis crassicaudata.

  It is concluded that transport to and storage of spermatozoa in the isthmus of the Fallopian tube, and their later migration up to the fertilization site and coincident transformation to a T shape, all are closely regulated by the ovarian follicular cycle in Sminthopsis.

  The data provide an opportunity to test the hypothesis that differences in relative testes mass, and perhaps sperm size, relate to interspecific differences in the amount of intermale sperm competition and in breeding systems.
