Abstract: Sperm production and allocation strategies have been a central concern of sperm competition research for the past 50 years. But during the ‘sexual cascade’ there may be strong selection for alternative routes to maximizing male fitness. Especially with the evolution of internal fertilization, a common and by now well-studied example is the accessory ejaculate investment represented by seminal fluid, the complex mixture of proteins, peptides and other components transferred to females together with sperm.

“…So far, we have focused on variation in Sfp gene sequences and the presence/absence of Sfps, but variation can also be quantitative: the amount of Sfps males make and transfer can vary between species, populations and individuals, or even within individuals across different contexts, and can have important consequences for male and female reproduction [10,83,84]. For example, males that mate repeatedly in quick succession become depleted of Sfps, which can lead to male infertility even while sperm continue to be transferred.…”

“…While research on seminal fluid continues apace [see 8,9], we know far less about the potential sexually selected roles of female reproductive fluid. For the purposes of the present review, we define female reproductive fluid (hereafter FRF) as the medium, arising from females, through which sperm must pass on © 2020 The Author(s) Published by the Royal Society.…”

“…Our data offer mixed support for the notion that seminal fluid proteins might contribute to this benefit of polyandry. Unlike genetic benefits that are expected to erode in the face of selection, variation in seminal fluid quality can vary between and within generations, for example, through variation in nutrition [32] or social environment [33], so that non-genetic paternal effects mediated via seminal fluid have the potential to contribute to the evolutionary maintenance of polyandry [34].…”
