Sperm: seminal fluid interactions and the adjustment of sperm quality in relation to female attractiveness
An important predictor of male fitness is the fertilizing efficiency of their ejaculates. Ejaculates are costly to produce and males are predicted to devote greater resources to copulations with reproductively superior females. It is well established that males allocate different numbers of sperm to ejaculates. However, less is known about how males adjust their sperm quality, which has importa...
متن کاملSeminal Fluid Affects Sperm Viability in a Cricket
Recent studies have suggested that males may vary the quality of their ejaculates in response to sperm competition, although the mechanisms by which they do so remain unclear. The viability of sperm is an important aspect of ejaculate quality that determines competitive fertilization success in the field cricket Teleogryllus oceanicus. Using in vitro mixtures of sperm and seminal fluid from pai...
متن کاملTactic-specific differences in seminal fluid influence sperm performance.
Seminal fluid often makes up a large part of an ejaculate, yet most empirical and theoretical studies on sperm competition have focused on how sperm characteristics (number and quality) affect fertilization success. However, seminal fluid influences own sperm performance and may potentially influence the outcome of sperm competition, by also affecting that of rivals. As a consequence males may ...
متن کاملOntogenetic changes in seminal fluid gene expression and the protein composition of cricket seminal fluid.
The ejaculates of most internally fertilizing species consists of both sperm and seminal fluid proteins. Seminal fluid proteins have been studied largely in relation to their post-mating effects on female reproductive physiology, and predominantly in genomically well-characterized species. Seminal fluids can also play important roles in sperm maturation and performance. In the field cricket Tel...
متن کاملMeiotic drive alters sperm competitive ability in stalk-eyed flies.
Meiotic drive results when sperm carrying a driving chromosome preferentially survive development. Meiotic drive should therefore influence sperm competition because drive males produce fewer sperm than non-drive males. Whether meiotic drive also influences the competitive ability of sperm after ejaculation is unknown. Here we report the results from reciprocal crosses that are designed for est...
