This study examines the question of whether multipartner matings by female primates, with resulting sperm competition among males, may have favored the evolution of biochemical mechanisms to enhance seminal coagulationand copulatory plug formation. Comparative ratings of seminal coagulation (using a four-point scale where 1 = no coagulation and 4 = copulatory plug formation) were obtained for 40 species representing 26 primate genera. Coagulation ratings were highest (mean = 3.64) in those… Expand
Copulatory plugs inhibit the reproductive success of rival males
TLDR
It is demonstrated that first males lost almost all paternity if they never formed a plug, and the copulatory plug of first males effectively blocked fertilization by second males, even if first males were vasectomized. Expand
Genetic and phenotypic influences on copulatory plug survival in mice
TLDR
Against intuition, plug survival time was negatively correlated with plug size: long-lasting plugs were small and relatively more susceptible to proteolysis, suggesting that changes in gene expression may play an important role in plug dynamics. Expand
DNA from copulatory plugs can give insights into sexual selection
TLDR
The authors' results confirm that D. spectabilis females mate with multiple males and suggest that they avoid mating with close relatives, and are consistent with the possibility that pressure generated during plug coagulation promotes movement of sperm beyond cervical barriers. Expand
Sperm Competition and Optimal Timing of Matings in Microcebus murinus
TLDR
Comparison with field data indicate that the timing of male monopolization efforts correspond with the optimal insemination period, which is during early receptivity, which indicates that early but not first mating males are more likely to sire offspring. Expand
Male-derived copulatory plugs enhance implantation success in female Mus musculus†
TLDR
It is demonstrated that copulatory plugs also influence the likelihood of implantation, which occurs roughly 4 days after copulation in mice, and it is shown that implantation rates significantly drop among females mated to genetically engineered males incapable of forming plugs. Expand
Evolution of sexual size monomorphism: the influence of passive mate guarding
TLDR
It is shown that, as predicted, copulatory plugs are negatively associated with degree of sexual dimorphism and females’ sexual receptivity length and penile spines are also significantly associated with plug use and short receptivity periods suggesting a possible offensive role in sperm competition. Expand
The molecular basis and reproductive function(s) of copulatory plugs
In many animals, male ejaculates coagulate to form what has been termed a copulatory plug, a structure that varies in size and shape but often fills and seals the female's reproductive tract. TheExpand
The seminal coagulum favours passage of fast-moving sperm into the uterus in the black-handed spider monkey.
TLDR
Whether the seminal coagulum of the black-handed spider monkey enhances sperm fertilisation chances by improving thefemale reproductive tract conditions, and if the female reproductive tract is 'blind' to semen or behaves selectively towards ejaculates of different males is investigated. Expand
Female control of mate plugging in a female-cannibalistic spider (Micaria sociabilis)
TLDR
This study demonstrates that the mating plug in M. sociabilis constitutes an effective male strategy to avoid sperm competition that seems to be under female control. Expand
Sperm competition and the evolution of male reproductive anatomy in rodents
TLDR
It is suggested that selection for larger plugs under sperm competition may explain variation in accessory gland size, and the need to consider both sperm and non-sperm components of the male ejaculate in the context of post-copulatory sexual selection is highlighted. Expand

1 – Sperm Competition and the Evolution of Ejaculates: Towards a Theory Base
TLDR
The chapter focuses on how a male allocates sperm among different ejaculates and summarizes a model framework for the analysis of this problem and illustrates, whether the female has a strong influence on the evolution of ejaculate characteristics, depending on how much control she can exercise on an ejaculate within her reproductive tract.

TLDR
It is indicated that these solitary lemurs are clearly subject to intrasexual selection and that male-male competition is primarily, but not exclusively, of the scramble type, and that social systems of solitary primates are more diverse than previously thought. Expand
