Previous data have indicated that orgasm produces marked alterations in plasma prolactin concentrations in men and women. Thus, the current study aimed to extend these data by examining prolactin response to coitus in healthy males and females. Ten pairs of healthy heterosexual couples participated in the study. Blood was drawn continuously for 20 min before, during, and until 60 min following sexual intercourse and orgasm. Plasma was subsequently analysed for prolactin concentrations. Coitus… Expand
Absence of orgasm-induced prolactin secretion in a healthy multi-orgasmic male subject
TLDR
Data from this multi-orgasmic subject support the hypothesized role of plasma prolactin in contributing to sexual-satiation mechanisms and suggest that prolactIn may form a feedback regulator of the refractory period following orgasm. Expand
Specificity of the neuroendocrine response to orgasm during sexual arousal in men.
TLDR
The results reinforce a role for prolactin either as a neuroendocrine reproductive reflex or as a feedback mechanism modulating dopaminergic systems in the central nervous system that are responsible for appetitive behavior. Expand
Orgasm-induced prolactin secretion: feedback control of sexual drive?
TLDR
A theoretical model of the role of PRL as a neuroendocrine reproductive reflex is proposed, suggesting that PRL may represent a peripheral regulatory factor for reproductive function, and/or a feedback mechanism that signals CNS centres controlling sexual arousal and behaviour. Expand
The post-orgasmic prolactin increase following intercourse is greater than following masturbation and suggests greater satiety
TLDR
Using data from three studies of men and women engaging in masturbation or penile-vaginal intercourse to orgasm in the laboratory, it is reported that for both sexes (adjusted for prolactin changes in a non-sexual control condition), the magnitude of Prolactin increase following intercourse is 400% greater than that following masturbation. Expand
Effects of acute prolactin manipulation on sexual drive and function in males.
TLDR
The data demonstrate that acute changes in prolactin plasma levels may be one factor modulating sexual drive and function, and may offer a new pharmacological approach for the treatment of sexual disorders. Expand
Prolactin secretory rhythm in women: immediate and long-term alterations after sexual contact.
TLDR
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. Expand
Prolactinergic and dopaminergic mechanisms underlying sexual arousal and orgasm in humans
TLDR
A brief overview of the physiology of dopamine and prolactin in regulating sexual behavior is provided and recent experimental and clinical evidence for a postulated feedback mechanism for Prolactin and its implications for orgasmic disorders are discussed. Expand
Effects of Sexual Arousal on Lymphocyte Subset Circulation and Cytokine Production in Man
TLDR
Findings demonstrate that components of the innate immune system are activated by sexual arousal and orgasm, and this study investigated the effects of masturbation-induced orgasm on lymphocyte circulation and cytokine production in healthy young males. Expand
No evidence for prolactin’s involvement in the post-ejaculatory refractory period
In many species, ejaculation is followed by a state of decreased sexual activity, the post-ejaculatory refractory period. Several lines of evidence have suggested prolactin, a pituitary hormoneExpand
No evidence for prolactin’s involvement in the post-ejaculatory refractory period
In many species, ejaculation is followed by a state of decreased sexual motivation, the post-ejaculatory refractory period. Several lines of evidence have suggested prolactin, a pituitary hormoneExpand

NEUROENDOCRINE AND CARDIOVASCULAR RESPONSE TO SEXUAL AROUSAL AND ORGASM IN MEN
TLDR
Orgasm induced transient increases in heart rate, blood pressure and noradrenaline plasma levels and none of the other endocrine variables were significantly affected by sexual arousal and orgasm. Expand
Neuroendocrine response to film-induced sexual arousal in men and women
TLDR
Analysis of prolactin, adrenaline, noradrenaline, and cortisol concentrations, together with cardiovascular variables of systolic/diastolic blood pressure and heart rate were undertaken during film-induced sexual arousal, demonstrating that increases in plasma Prolactin during sexual stimulation are orgasm-dependent and suggesting that prolact in may regulate a negative-feedback sexual-satiation mechanism. Expand
Cardiovascular and endocrine alterations after masturbation-induced orgasm in women.
TLDR
Sexual arousal and orgasm produce a distinct pattern of neuroendocrine alterations in women, primarily inducing a long-lasting elevation in plasma prolactin concentrations, suggesting that Prolactin is an endocrine marker of sexual aroused and orgasm. Expand
Suppression by prolactin of the electrically induced erectile response through its direct effect on the corpus cavernosum penis in the dog.
TLDR
An excess of prolactin directly inhibited the smooth muscle relaxation of corpus cavernosum penis and contributed to men becoming impotent when exposed to hyperprolactinemia. Expand
Effects of chronic hyperprolactinemia on sexual arousal and erectile function in male rats.
TLDR
The pituitary-grafted animals showed a significant reduction in latency to the first erection with each successive test, suggesting a delayed recovery from increased supraspinal inhibitory input. Expand
Prolactin release after mating and genitosensory stimulation in females.
TLDR
The natural mating condition reveals the contributions of the short-term and long-term mnemonic devices, establishing the existence of a graded to all-or-nothing transition that is required for the occurrence of PSP. Expand
Hormone-neurotransmitter interactions in the control of sexual behavior
TLDR
R reciprocal changes in DA and 5-HT release in different areas of the brain may promote copulation and sexual satiety, respectively. Expand
Dual modulation of male sexual behavior in rats by central prolactin: relationship with in vivo striatal dopaminergic activity
TLDR
Sexual behavioral and in vivo neurochemical data obtained from adult male rats injected intracerebroventricularly acutely or chronically with ovine prolactin show that acute and chronic central oPRL treatments have stimulatory and inhibitory effects on male sexual behavior, respectively and suggest that behavioral effects of PRL occur simultaneously with changes in striatal dopaminergic activity.

Suppressive effects of chronic hyperprolactinemia on penile erection and yawning following administration of apomorphine to pituitary-transplanted rats.
TLDR
The results indicated that the pituitary transplantation with chronic excess of PRL and castration with T deficiency caused roughly comparable degrees of suppression of penile erectile activity through mechanisms presumably independent from one another in the rat. Expand
Prolactin regulation of tuberoinfundibular dopaminergic neurons: immunoneutralization studies
TLDR
Results confirm that prolactin mediates the stimulatory effects of haloperidol on tuberoinfundibular DA neurons, and reveal that delayed induced activation of these neurons by Prolactin is dependent upon a priming period of sustained hyperprolactinemia longer than 3 h for initiation and maintenance of this response.
