DOI: 10.1002/bies.202000109
Abstract: Drosophila males sing a courtship song to achieve copulations with females. Females were recently found to sing a distinct song during copulation, which depends on male seminal fluid transfer and delays female remating. Here, it… read more here.

DOI: 10.1007/s00265-019-2733-5
Abstract: Sexual conflict has been shown to shape many behaviors in the reproductive context, such as the duration of copulation, across a broad taxonomic range. In spiders, copulation duration is one of the most variable reproductive… read more here.

Genetic variation in sexual aggression and the factors that determine forced copulation success

DOI: 10.1016/j.anbehav.2019.09.015
Abstract: Sexual conflict is common in nature and sometimes results in sexual aggression. An extreme case is forced copulation, where one individual forcibly mates with another individual who resists the mating. To understand what makes some… read more here.

Mating induces production of MMP2 in the llama oviduct: Analysis of MMP2 effect on semen.

DOI: 10.1016/j.anireprosci.2018.03.016
Abstract: Ovulation of South American Camelids is induced by mating. After copulation, sperm are stored into the oviduct to be released near ovulation time. To study whether copulation induces matrix metalloproteinase-2 (MMP2) secretion in the oviduct,… read more here.

DOI: 10.1016/j.cub.2021.02.003
Abstract: Darwin argued that females' "taste for the beautiful" drives the evolution of male extravagance,1 but sexual selection theory also predicts that extravagant ornaments can arise from sexual conflict and deception.2,3 The sensory trap hypothesis posits… read more here.

DOI: 10.1016/j.psyneuen.2019.05.025
Abstract: The medial preoptic nucleus (MPN) plays an essential role in the control of male sexual behavior. In rats, the central part of the MPN (MPNc) contains a sexually dimorphic nucleus exhibiting male-biased morphological sex differences.… read more here.

DOI: 10.1093/aesa/saab019
Abstract: Abstract Finding a partner to mate with may be only part of ensuring successful siring of offspring. Females often exhibit cryptic female choice (CFC) during or after copulation, which can influence whose sperm from her… read more here.

Male–female interactions drive the (un)repeatability of copula duration in an insect
Sign Up to like & getrecommendations! Published in 2017 at "Royal Society Open Science"
DOI: 10.1098/rsos.160962
Abstract: Across the animal kingdom the duration of copulation varies enormously from a few seconds to several days. Functional explanations for this variation are largely embedded within sperm competition theory in which males modulate the duration… read more here.

DOI: 10.1098/rspb.2017.1265
Abstract: Genitalia are morphologically variable across many taxa and in physical contact during intromission, but little is known about how variation in form correlates with function during copulation. Marine mammals offer important insights into the evolutionary… read more here.

Abstract: Background Asymmetric genitalia have repeatedly evolved in animals, yet the underlying causes for their evolution are mostly unknown. The fruitfly Drosophila pachea has asymmetric external genitalia and an asymmetric phallus with a right-sided gonopore. The… read more here.

DOI: 10.1101/pdb.prot108108
Abstract: Upon copulation, females undergo a switch-like change in their behavior and physiology, known as "postmating responses." These strong behavioral and physiological changes are triggered by the transfer of male seminal proteins during copulation. Postmating response… read more here.
