The morphology of the spermatozoon of representative species of the subfamily Nesomyinae Muroidea: Nesomyidae , a monophyletic group of rodents endemic to Madagascar, was examined by light and electron microscopy to determine the sperm head shape and tail length across the species. Marked interspecific differences were found to occur in both the form of the sperm head and length of the tail. The species that possess a sperm head with an apical hook, which largely contains acrosomal material, generally displayed longer sperm tails, and a species with a spatulate sperm head had the shortest tail.

Lookup the document at:. Ibraheem, M. Minia Univ. Sperm morphology of the dipodid rodents Jerboas common in Egypt. Sperm morphology of the jerboas Allactaga and Jaculus species common in Egypt was described by light and transmission electron microscopy. Two morphs of spermatozoa were observed among these dipodids. One type observed in the smaller jerboa, Allactaga tetradactyla, has a paddle-shaped long head, long tail, and the connecting piece of tail inserts off-centre at the base of the sperm head.

Cell and Tissue Research. Sperm morphology among the various members of the genus Pseudomys showed great interspecific variation. The top hook contained nuclear, subacrosomal and acrosomal material, whereas the two lower ventral hooks displayed largely only an extension of the subacrosomal material.
