- 摘要：
- Theory assumes that postcopulatory sexual selection favours increased investment in testes size because greater numbers of sperm within the ejaculate
Data from: Evolution of reduced postcopulatory molecular interactions in Drosophila populations lacking sperm competition

- 摘要：
- In many species with internal fertilization, molecules transferred in the male ejaculate trigger and interact with physiological changes in females
Data from: Sperm production characteristics vary with level of sperm competition in Cataglyphis desert ants

- DOI：
- doi:10.5061/dryad.v7000
- 摘要：
- level of sperm competition selects for larger numbers of sperm in ejaculates. Sperm competition is also thought to promote the evolution of longer sperm
Data from: Female social preference for males that have evolved via monogamy: evidence of a trade-off between pre- and post-copula

- 摘要：
- e confirmed that sperm competition selects for both increased ejaculate quality and elevated offspring viability. Fewer investigations have explored whether
