Complexity of seminal fluid: a review
TLDR
The diversity of microorganismal, cellular and molecular components of seminal fluids can be interpreted in the light of emergence of co-adapted complexes, host–parasite coevolution, male–female arms races, sperm competition, pleiotropy and redundancy of function.Abstract:
The seminal fluid is a complex medium containing a great variety of molecules, mainly produced by sex accessory glands, and also cells other than spermatozoa (e.g. leucocytes). In this paper, I review current knowledge on composition of seminal fluid in both vertebrates (mainly mammals) and invertebrates (mainly insects) with internal fertilisation, in the light of possible benefits of seminal fluid components to males (e.g. sperm capacitation, sperm competition and fertilisation), possible costs to males (e.g. autoimmunity, antigenic effects), potential benefits to females being inseminated (e.g. food, immunostimulation and antibiotic effects) and potential costs to females (e.g. transmission of venereal diseases). The diversity of microorganismal, cellular and molecular components of seminal fluids can be interpreted in the light of emergence of co-adapted complexes, host–parasite coevolution, male–female arms races, sperm competition, pleiotropy and redundancy of function.read more

Insect seminal fluid proteins: identification and function.
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.

Sperm competition and ejaculate economics.
Geoff A. Parker,Tommaso Pizzari +1 more
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.

Exosomes in human semen carry a distinctive repertoire of small non-coding RNAs with potential regulatory functions
Lucia Vojtech,Sangsoon Woo,Sean M. Hughes,Claire N. Levy,Lamar Ballweber,Renan Sauteraud,Johanna Strobl,Katharine Westerberg,Raphael Gottardo,Muneesh Tewari,Florian Hladik +10 more
TL;DR: It is found that seminal exosome (SE) preparations contain a substantial amount of RNA from 20 to 100 nucleotides (nts) in length, which could potentially deliver regulatory signals to the recipient mucosa via transfer of small RNA molecules.

Seminal influences: Drosophila Acps and the molecular interplay between males and females during reproduction
K. Ravi Ram,Mariana F. Wolfner +1 more
TL;DR: Understanding how Acps elicit particular female responses will provide insights into reproductive biology and chemical communication, tools for analyzing models of sexual cooperation and/or sexual conflict, and information potentially useful for strategies for managing insect pests.

Proteomics Reveals Novel Drosophila Seminal Fluid Proteins Transferred at Mating
TL;DR: A novel proteomic method that uses whole-organism isotopic labeling to detect transferred Sfps in mated female D. melanogaster and identifies 63 proteins, which were previously unknown to function in reproduction, and confirmed the transfer of dozens of predicted Sfps.

Physiological Functions of Glucocorticoids in Stress and Their Relation to Pharmacological Actions
TL;DR: It is proposed that stress-induced increases in glucocorticoid levels protect not against the source of stress itself but rather against the body's normal reactions to stress, preventing those reactions from overshooting and themselves threatening homeostasis.

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.
