How do we love? Romantic love style in men is related to lower testosterone levels.

The results pointed out that low testosterone concentrations are associated with higher score for Eros, Ludus, Pragma, Mania love style and no significant association was proved for other tested parameters of androgenicity and love style after correction was applied.

Prolactin secretory rhythm in women: immediate and long-term alterations after sexual contact.

A long-term change in the PRL secretory rhythm after sexual intercourse with orgasm in females is demonstrated, suggesting memory effects, and it is hypothesized that the additionally secreted PRL could be beneficial for decidualization and implantation.

Testosterone and Sexual Desire in Healthy Women and Men

Sexual desire is typically higher in men than in women, with testosterone (T) thought to account for this difference as well as within-sex variation in desire in both women and men. However, few

Emotional states of love moderate the association between catecholamines and female sexual responses in the laboratory.

It is feasible that, when women are seeking a partner (Lust), norepinephrine and dopamine may facilitate attention toward sexually relevant stimuli.

The Science of Love: State of the Art.

It is proposed that the early stage of love, generally called romantic love, is the result of the activation of the brain limbic structures regulating fear/anxiety reactions leading to changes of major neurotransmitters, such as increased monoamine levels and decreased serotonin concentrations.

Oxytocin and social motivation

Current Evidence of the Monoaminergic Regulation of Romantic Love and Relationship

Romantic love is vulnerable for secondary effect, such as drugs which modulate the dopamine and serotonin, in human, and is also impacted by the polymorphism of monoamine receptors.



Alteration of the platelet serotonin transporter in romantic love.

The main finding of the present study is that subjects who were in the early romantic phase of a love relationship were not different from OCD patients in terms of the density of the platelet 5-HT transporter, which proved to be significantly lower than in the normal controls.

Testosterone levels in healthy men and the relation to behavioural and physical characteristics: facts and constructs.

This review summarises the correlations between testosterone levels and male physical appearance and behaviour and suggests that both generalisation and individualisation of study results will lead to doubtful conclusions and prejudices.

Speculations Concerning the Physiological Significance of Central Oxytocin in Maternal Behavior

Oxytocin is an important neurohormone involved in the response to stress, and it is proposed that many of the behavioral effects exerted by this neuropeptide may be the result of the underlying influence of stress.

Relationship between plasma profiles of oxytocin and adrenocorticotropic hormone during suckling or breast stimulation in women.

Data show an inverse relationship between plasma OT and ACTH levels during suckling and breast stimulation in humans, suggesting an inhibitory influence of OT on ACTH/cortisol secretion in a physiological condition.

The neural basis of romantic love

The activity in the brains of 17 subjects who were deeply in love was scanned using fMRI, suggesting that a unique network of areas is responsible for evoking this affective state, and postulate that the principle of functional specialization in the cortex applies to affective states as well.

Modulation of pair bonding in female prairie voles (Microtus ochrogaster) by corticosterone.

The involvement of the adrenal axis in the formation of partner preferences and the subsequent development of pair bonds provides a mechanism through which environmental and social factors may influence social organization in this species.

Peptides, Steroids, and Pair Bonding a

Studies in prairie voles are used here to examine evidence for an effect on pair bonding of two general classes of hormones: neuropeptides, with emphasis on oxytocin and vasopressin, and steroids, including hormones produced by the gonads and the adrenal cortex.

Findings are consistent with neuroendocrine interactions known or hypothesized to occur during major depressive disorders in humans and raise unique possibilities for comparative research in human and nonhuman primates.
