Secretions of male accessory glands contain a variety of bioactive molecules. When transferred during mating, these molecules exert wide-ranging effects on female reproductive activity and they improve the male's chances of siring a significant proportion of the female's offspring. The accessory gland secretions may affect virtually all aspects of the female's reproductive activity. The secretions may render her unwilling or unable to remate for some time, facilitating sperm storage and ensuring that any eggs laid will be fertilized by that male's sperm. They may stimulate an increase in the number and rate of development of eggs and modulate ovulation and/or oviposition. Antimicrobial agents in the secretions ensure that the female reproductive tract is a hospitable environment during sperm transfer. In a few species the secretions include noxious chemicals. These are sequestered by developing eggs that are thereby protected from predators and pathogens when laid.read more

TL;DR: Recent identification of insect SFPs is reviewed and the multiple roles these proteins play in the postmating processes of female insects are discussed.

The cost of reproduction: the devil in the details
TL;DR: Recent studies in five areas examining the proximate mechanisms underlying the cost of reproduction provide new information about mechanisms that comprise 'the cost', but also hint at an underlying evolutionarily conserved causal mechanism.

TL;DR: It is argued that ejaculate economic theory represents a powerful heuristic to explain the diversity in ejaculate traits at multiple levels: across species, across males and within individual males.

TL;DR: RNA interference was used to suppress SP expression, to determine whether SP is required to elicit full post-mating responses, the magnitude of responses due to other seminal fluid components, and whether SP accounts for the “sperm effect.”

Cuticular Hydrocarbons: Their Evolution and Roles in Drosophila Pheromonal Communication
TL;DR: Using a model involving the stimulating or the inhibiting role of CHs, it is possible to speculate on the mechanisms of CH perception and on the role(s) that these substances could play on sexual isolation and onThe evolution of pheromonal communication.

Female control : sexual selection by cryptic female choice
TL;DR: A growing body of evidence has begun to reveal flaws in the traditional assumption of female passivity and lack of discrimination after copulation has begun as discussed by the authors, and evidence from various fields indicates that such selectivity by females may be the norm rather than the exception.

Cost of mating in Drosophila melanogaster females is mediated by male accessory gland products
TL;DR: 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.

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.
