. Normal live birth after testicular sperm extraction and intracytoplasmic sperm injection in variant primary ciliary dyskinesia with completely immotile sperm and structurally abnormal sperm tails. Fertil Steril. 2012;97:313-8 pubmed publisher
..Despite testicular sperm also being immotile and showing profound structural defects that would seem to preclude fertilization, more morphologically normal sperm are capable of establishing a normal pregnancy. ..
Breed W. The spermatozoon of Eurasian murine rodents: Its morphological diversity and evolution. J Morphol. 2004;261:52-69 pubmed
..The ultrastructural organization of the sperm head of Bandicota, but not those of Micromys or Tokudaia, suggest divergence in some of the morphological events associated with sperm-egg interaction at the time of fertilization...
Breed W. Evolution of the spermatozoon in muroid rodents. J Morphol. 2005;265:271-90 pubmed

Matson P, Kappelle W, Malecki I. The use of a hypo-osmotic swelling (HOS) test on sperm of the pig (Sus scrofa domesticus), emu (Dromaius novaehollandiae), Asian elephant (Elephas maximus), hamadryas baboon (Papio hamadryas hamadryas), and central rock rat (Zyzomys pedunculatus). Reprod Biol. 2009;9:181-7 pubmed
..A solution of TALP-HEPES medium at 100 mOsm/kg would be suitable to obtain the maximal response in this range of mammals tested, though it would need to be diluted to at least 50 mOsm/kg when testing the viability of the emu sperm...
Fitzpatrick J, Garcia Gonzalez F, Evans J. Linking sperm length and velocity: the importance of intramale variation. Biol Lett. 2010;6:797-9 pubmed publisher
..Our findings also suggest that selection for faster swimming sperm may promote the evolution of longer sperm, thereby supporting recent findings from macroevolutionary studies...
