Silent or Vocalizing Rats Copulate in a Similar Manner
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-12-03)
Both male and female rats produce 50 kHz ultrasonic vocalizations (USVs) in the presence of a sexual partner and during copulation. Previous studies showed that USVs have no incentive value for rats. In this study, we evaluated the role of USVs in behavior during copulation. Three groups of rats were used: sham males paired with sham females, devocalized females paired with sham males, and sham ...
A cooperative function for multisensory stimuli in the induction of approach behavior of a potential mate
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-03-17)
Intrasexual competition is an important element of natural selection in which the most attractive conspecific has a considerable reproductive advantage over the others. The conspecifics that are approached first often become the preferred mate partners, and could thus from a biological perspective have a reproductive advantage. This underlines the importance of the initial approach and raises the ...
Perinatal fluoxetine exposure changes social and stress-coping behavior in adult rats housed in a seminatural environment
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-06)
The use of selective serotonin reuptake inhibitors (SSRI) during pregnancy has increased tremendously, but the consequences for the offspring remain largely unclear. Several studies have described potential effects of perinatal SSRI-exposure on neurobehavioral outcomes using simplified rodent test set-ups, however these set-ups only assess a small fraction of the behavior. For translational purposes ...
Mate Choice could be Random in Female Rats (Rattus norvegicus)
(Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2017-11-01)
Female mate choice is often investigated in terms of reproductive success in order to understand how male characteristics contribute to sexual attractiveness. Previous studies have found that females rats prefer mating with their first encounter rather than males visited subsequently, suggesting that the rewarding value of this first encounter is enough to reinforce mating with the first partner. ...
The role of adrenoceptors in the central nervous system in male and female rat sexual behavior
(Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2014-09-10)
Three different phases can be distinguished in rats’ sexual cycle, the introductory (precopulatory), the copulatory and the executive (ejaculatory) phases. In this review, a new analysis of existing pharmacological data is made, both in male and female rats, in which the different aspects of sexual behavior are taken into account. An effort is made to distinguish pharmacological effects on sexual ...
Functions of Vocalization in Sociosexual Behaviors in Rats (Rattus norvegicus) in a Seminatural Environment
(Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2017-01-09)
Both male and female rats produce vocalizations in the presence of a potential sexual partner. In this study, we evaluated the role of vocalizations in sociosexual behaviors in an ecologically valid procedure. Three males and 4 females were housed in a seminatural environment. In each group, 1 or 2 males and females were devocalized, and the other subjects were sham operated. Sociosexual interactions ...
Preface for Marcel Waldinger special issue on premature ejaculation
(Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2019-09-13)
The world lost a very dear and brilliant man when Prof Dr Marcel Waldinger passed away this year. I am proud that I got to know him well, and had the chance to learn a lot from him as a scientist. He was passionate about his work related to men and womens sexual dysfunctions, with a special focus on PE, postorgasm illness syndrome, and persistent sexual arousal syndrome.

Third-party prosocial behavior in adult female rats is impaired after perinatal fluoxetine exposure
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-26)
SSRIs are commonly used to treat pregnant women with depression. However, SSRIs can cross the placenta and affect the development of the fetus. The effects of perinatal SSRI exposure, and especially the effects on social behavior, are still incompletely documented. This study first aims to investigate whether rats show prosocial behavior in the form of consolation behavior. Secondly, it aims to ...
Role of Oestrogen α Receptors in Sociosexual Behaviour in Female Rats Housed in a Seminatural Environment
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-08-28)
The present study investigated the role of oestrogen receptor (ER)α in the ventromedial nucleus of the hypothalamus (VMN), the preoptic area (POA), the medial amygdala (MePD) and the bed nucleus of stria terminalis (BNST) in sociosexual behaviour in female rats. This was conducted in two sets of experiments, with the VMN and POA investigated in the first set, and the MePD and BNST in the second set. ...
