  • motility
  • It has several documented biological functions including: Supporting the sperm by: a.) enabling sperm to undergo biochemical transitions, called capacitation and motility hyperactivation, in which they become physiologically capable of fertilizing an oocyte (e.g. mammals) and b.) maintaining sperm viability until an oocyte is ovulated (e.g. insects and mammals). (wikipedia.org)
  • oocyte
  • Female sperm storage is a biological process and often a type of sexual selection in which sperm cells transferred to a female during mating are temporarily retained within a specific part of the reproductive tract before the oocyte, or egg, is fertilized. (wikipedia.org)
  • storage tubules
  • The site of storage is variable among different animal taxa and ranges from structures that appear to function solely for sperm retention, such as insect spermatheca and bird sperm storage tubules (bird anatomy), to more general regions of the reproductive tract enriched with receptors to which sperm associate before fertilization, such as the caudal portion of the cow oviduct containing sperm-associating annexins. (wikipedia.org)
  • genes
  • Since many environments require different traits for success, females are somehow able to match sperm (acquired from multiple mates) that have the best genes for whichever environment in which they will develop. (wikipedia.org)
  • genetic
  • One important advantage female insects that store sperm gain is increased genetic diversity in their offspring. (wikipedia.org)
  • species
  • Though it has been shown that a majority of female insect species can store sperm, specific examples that have been studied could include field crickets, dung flies and Mediterranean fruit flies. (wikipedia.org)
  • males
  • Serving as an arena in which sperm from different mating males compete for access to oocytes, a process called sperm competition, and in which females may preferentially utilize sperm from some males over those of others, called female sperm preference or cryptic female choice (e.g. many invertebrate animals, birds and reptiles). (wikipedia.org)
  • Another way sperm-storing females can alter the diversity of their offspring is controlling the relatedness to the males that provide them with sperm. (wikipedia.org)
  • Being able to choose between sperm after coupling might be advantageous to females because choosing between mates precopulation may be more costly, or it may just be too difficult to tell males apart before mating. (wikipedia.org)
