How sperm from competing males are used to fertilize eggs is poorly understood yet has important implications for postcopulatory sexual selection. Sperm may be used in direct proportion to their numerical representation within the fertilization set or with a bias toward one male over another. Previous theoretical treatments have assumed a single sperm-storage organ, but many taxa possess multiple organs or store sperm within multiple regions of the reproductive tract. In Drosophila, females… 

Female mediation of competitive fertilization success in Drosophila melanogaster

The results demonstrate that females do not simply provide a static arena for sperm competition but rather play an active and pivotal role in postcopulatory processes, and resolve the adaptive significance of genetic variation in female-mediated mechanisms of sperm handling.

RAPID DIVERSIFICATION OF SPERM PRECEDENCE TRAITS AND PROCESSES AMONG THREE SIBLING DROSOPHILA SPECIES

These species differences are evaluated in light of concurrent investigations of within‐population variation in competitive fertilization success and postmating/prezygotic reproductive isolation in hybrid matings between species to forge an understanding of the relationship between microevolutionary processes and macroevolutionARY patterns as pertains to postcopulatory sexual selection in this group.

A review of sperm storage methods and post-copulatory sexual selection in the Cephalopoda

This review summarizes the sperm storage methods and the mechanisms of post-copulatory sexual selection in cephalopods and it is proposed that these diverse methods evolved as adaptive mechanisms through post-CopulatorySexual selection.

The life history of Drosophila sperm involves molecular continuity between male and female reproductive tracts

The data reveal a molecular “hand-off” from males to females, which is postulate to be an important component of sperm–female interactions.

Multiple mechanisms of cryptic female choice act on intraspecific male variation in Drosophila simulans

If and how female D. simulans employ these two mechanisms of CFC in response to intraspecific male size variation is explored, suggesting that females use different CFC mechanisms to select for different male traits.

Sperm metabolic rate predicts female mating frequency across Drosophila species

The results demonstrate the importance of sperm metabolism in sexual selection by measuring sperm metabolism across 13 Drosophila species and comparing these measures to published data on female mating rate and on sperm length.

Do Candidate Genes Mediating Conspecific Sperm Precedence Affect Sperm Competitive Ability Within Species? A Test Case in Drosophila

The results suggest that CG14891 and CG6864 might have been co-opted from an intraspecies gene function into an interspecies avoidance phenotype (i.e., CSP) and the dual role of these genes could be a consequence of their pleiotropic roles.

Structural variation in Drosophila melanogaster spermathecal ducts and its association with sperm competition dynamics

It is reported that some Drosophila melanogaster females exhibit previously uncharacterised structures within the distal portion of the muscular duct that links a spermatheca to the uterus, which raises the possibility that SDPs provide a mechanism for variation in sperm competition outcome among females.

Resolving Mechanisms of Competitive Fertilization Success in Drosophila melanogaster

Sperm showed more mobility within the female storage organs than expected, with those from the most recent copulation displacing sperm from previous males; however, sperm viability remained consistent over long-term storage and each male's sperm was equally competitive in fertilizing the female's eggs.

Evidence for biased use of sperm sources in wild female giant cuttlefish (Sepia apama)

The structure of the sperm stores in the female's buccal area is described, microsatellite DNA analyses are used to determine the genetic diversity of stored sperm and the number of male genotypes represented in the sperm receptacles was significantly lower than that found among the spermatangia.

Resolving variation in the reproductive tradeoff between sperm size and number

Comparing passerine birds and Drosophila fruit flies with different sperm competition mechanisms provides convincing evidence for the existence of a sperm size–number tradeoff and shows that by considering both sperm competition mechanism and dilution, can the authors account for variation in sperm size between different taxa.

MECHANISMS UNDERLYING THE SPERM QUALITY ADVANTAGE IN DROSOPHILA MELANOGASTER

It is empirically demonstrate for Drosophila melanogaster that both sperm quality and sperm quantity independently contribute to competitive male fertilization success, and exemplify that primary sex cells can bear secondary sexual straits.

Evolution of intra‐ejaculate sperm interactions: do sperm cooperate?

Current evidence insufficient to support the concept of sperm control over their form or function is found, and sperm heteromorphism and conjugation should be interpreted not as cooperation but rather as traits selected at the level of the male, much like other ejaculatory traits such as accessory gland proteins and ejaculate size.

Why do Females Make it so Difficult for Males to Fertilize their Eggs

If females have evolved more and more effective barriers to sperm in their reproductive tract as means of mate choice, coevolution between female anti-sperm responses and male abilities to overcome these will result in increasingly elaborate forms of female hostility towards sperm.

In this sperm–heteromorphic species, the observations show definitively that in nature, as well as in the laboratory, only the long sperm morph participates in fertilization.

Oh, the places they’ll go

Male and female factors, as well as their interactions, involved in female sperm storage and differential male fertilization success are described.
