TLDR
It is demonstrated here that seminal fluid products from the main cells of the male accessory gland are responsible for the cost of mating in females, and that increasing exposure to these products increases female death rate.Abstract:
Female Drosophila melanogaster with environmentally or genetically elevated rates of mating die younger than controls. This cost of mating is not attributable to receipt of sperm. We demonstrate here that seminal fluid products from the main cells of the male accessory gland are responsible for the cost of mating in females, and that increasing exposure to these products increases female death rate. Main-cell products are also involved in elevating the rate of female egg-laying, in reducing female receptivity to further matings and in removing or destroying sperm of previous mates. The cost of mating to females may therefore represent a side-effect of evolutionary conflict between males.read more

Why do females mate multiply? A review of the genetic benefits.
TL;DR: It is concluded that post‐copulatory mechanisms provide a more reliable way of selecting a genetically compatible mate than pre-copulatory mate choice and that some of the best evidence for cryptic female choice by sperm selection is due to selection of more compatible sperm.

The evolution of polyandry : multiple mating and female fitness in insects
Göran Arnqvist,Tina Nilsson +1 more
TL;DR: A meta-analysis of 122 experimental studies addressing the direct effects of multiple mating on female fitness in insects shows that females gain directly from multiple matings in terms of increased lifetime offspring production, and supports the existence of an intermediate optimal female mating rate.

The rapid evolution of reproductive proteins.
TL;DR: Sequence comparisons and functional studies are beginning to show the extent to which the rapid divergence of reproductive proteins is involved in the speciation process.

Sexually antagonistic male adaptation triggered by experimental arrest of female evolution
TL;DR: It is shown that when female D. melanogaster are experimentally prevented from coevolving with males, males rapidly adapt to the static female phenotype, which leads to a reduction in female survivorship, which is mediated by an increased rate of remating and increased toxicity of seminal fluid.
Journal ArticleDOI
The evolution of mate choice and mating biases
TL;DR: It is argued that progress in understanding the evolution of mate choice is currently hampered by spurious distinctions among models and a misguided tendency to test the processes underlying each model as mutually exclusive alternatives.

Sexual selection and the descent of man, 1871-1971
TL;DR: In the first full discussion of sexual selection since 1871, leading biologists brought modern genetic theory and behavior observation to bear on the subject as mentioned in this paper, and the result is a remarkably original and well-rounded view of the whole concept that will be invaluable especially to students of evolution and human sexual behavior.

A male accessory gland peptide that regulates reproductive behavior of female D. melanogaster
TL;DR: Amino acid sequencing of the purified peptide and oligonucleotide-directed cDNA cloning established that the peptide consists of 36 amino acids, and appears to be synthesized as a precursor with a hydrophobic signal sequence of 19 residues at its N-terminal end.

A cost of mating in female fruitflies
Kevin Fowler,Linda Partridge +1 more
TL;DR: It is shown here that mating with males greatly reduces lifespan in female fruitflies whose rates of egg-production and egg-fertility do not differ, suggesting both that simple nutrient allocation to reproduction is not its only physiological cost, and that males can cause females to remate at a frequency that results in reduced female lifetime reproductive success.
