The typical sperm is comprised of a head, midpiece and flagellum. Around this theme there is an enormous diversity of form ‐ giant sperm, multi‐flagellate sperm and also sperm that lack flagella entirely. Explaining this diversity in sperm morphology is a challenging question that evolutionary biologists have only recently engaged in. Nonetheless, one of the selective forces identified as being an important factor in the evolution of sperm form is sperm competition, which occurs when the sperm… 

Morphological diversity of sperm: A mini review

The accumulated knowledge indicates evolution of sperm morphology across species has some associations with female reproductive tract, sperm competition and sperm size and number, however interpreting these results for phylogentic correlations should be approached with caution.

Mating behavior and the evolution of sperm design

The results suggest that the interactions between sperm donor, sperm, and sperm recipient can change drastically when hypodermic insemination evolves, involving convergent evolution of a needle-like copulatory organ, a simpler sperm design, and a simpler female genital morphology.

Insect Sperm Motility

This review updates the present knowledge of the proximate and ultimate aspects of insect sperm motility and throws light on the selective mechanisms that shape insect sperm structure and function.

Methodological considerations for examining the relationship between sperm morphology and motility

Results from studies linking morphology to motility enhance the authors' understanding of the evolution of adaptive sperm traits and the mechanisms that regulate fertility, thus offering new insights into methods used in assisted reproductive technologies in animal science, conservation and public health.

The physiological acquisition of amoeboid motility in nematode sperm: Is the tail the only thing the sperm lost?

Compelling evidence shows that pseudopod extension is under the regulation of physiological events also observed in other eukaryotic cells (including flagellated sperm) that involve membrane rearrangements in response to extracellular cues that initiate various signal transduction pathways.

Evolution of female sperm-storage organs in the carrefour of stylommatophoran gastropods

The results indicate that postcopulatory sexual selection as well as life history and habitat specificity may have influenced the evolution of female sperm-storage organs in hermaphroditic gastropods.

Collective dynamics of sperm cells

Experimental observations of collective dynamics of sperm group dynamics, as well as recent mechanistic models that link the motion of individual sperm cells and their flagella to observed collective dynamics, are discussed.

The origin of nematode sperm: Progenesis at the cellular level

The origin of the aberrant sperm of nematodes and many other metazoans with internal insemination may be interpreted as progenesis at the cellular level.



Evolution of sperm size in nematodes: sperm competition favours larger sperm

It was found that sperm size differed significantly with reproductive mode: males of gonochoristic species had significantly larger sperm than did males of the hermaphroditic species.

The evolution of sperm length in moths

a comparative study examining how sperm lengths are associated with male and female reproductive characters across moths found a positive relationship between the residual testis volume and spermathecal volume, suggesting coevolution between male investment in sperMatogenesis and the extent of the female sperm storage capacity.

Sexual selection and insect sperm.

These hypotheses have 2 difficulties explaining the full range of insect sperm-to-egg ratios: i) Even in insects whose females mate only once, males transfer excess sperm, and ii) Neither specifies an advantage to females who accept excessive numbers of sperm.

Mating system evolution in sperm-heteromorphic Drosophila.


It is suggested that future models of sperm‐size evolution consider not only the role of sperm competition, but also how female control and manipulation of ejaculates after insemination selects for different sperm morphologies.

Sperm Competition in Fishes: The Evolution of Testis Size and Ejaculate Characteristics

It is found that both the gonadosomatic index and sperm numbers increase with intensity of sperm competition across species but that sperm length decreases, which does not fit predictions of current sperm competition theory.

Only long sperm are fertilization-competent in six sperm-heteromorphic Drosophila species


The possible advantages to a species of internal rather than external fertilization have frequently been stressed, though one important point appears persistently to have escaped comment. In terms of
