sexual satisfaction sexual compatibility and relationship adjustment in couples the role of sexual behaviors Orgasm and men s discernment of women s intercourse Orgasm
The Journal of Sexual Medicine, 2015Co-Authors: Kateřina Klapilova, Stuart Brody, Lucie Krejcova, Barbara Husarova, Jakub BinterAbstract:Abstract Introduction Research indicated that (i) vaginal Orgasm consistency is associated with indices of psychological, intimate relationship, and physiological functioning, and (ii) masturbation is adversely associated with some such measures. Aim The aim of this study was to examine the association of various dyadic and masturbation behavior frequencies and percentage of female Orgasms during these activities with: (i) measures of dyadic adjustment; (ii) sexual satisfaction; and (iii) compatibility perceived by both partners. Methods In a sample of 85 Czech long‐term couples (aged 20–40; mean relationship length 5.4 years), both partners provided details of recent sexual behaviors and completed sexual satisfaction, Spanier dyadic adjustment, and Hurlbert sexual compatibility measures. Multiple regression analyses were used. Main Outcome Measure The association of sexual behaviors with dyadic adjustment, sexual compatibility, and satisfaction was analyzed. Results In multivariate analyses, women's dyadic adjustment is independently predicted by greater vaginal Orgasm consistency and lower frequency of women's masturbation. For both sexes, sexual compatibility was independently predicted by higher frequency of penile–vaginal intercourse and greater vaginal Orgasm consistency. Women's sexual satisfaction score was significantly predicted by greater vaginal Orgasm consistency, frequency of partner genital stimulation, and negatively with masturbation. Men's sexual satisfaction score was significantly predicted by greater intercourse frequency and any vaginal Orgasm of their female partners. Concordance of partner vaginal Orgasm consistency estimates was associated with greater dyadic adjustment. Conclusions The findings suggest that specifically penile–vaginal intercourse frequency and vaginal Orgasm consistency are associated with indices of greater intimate relationship adjustment, satisfaction, and compatibility of both partners, and that women's masturbation is independently inversely associated with measures of dyadic and personal function. Results are discussed in light of previous research and an evolutionary theory of vaginal Orgasm. Klapilova K, Brody S, Krejcova L, Husarova B, and Binter J.

Orgasm and women's waist circumference
European Journal of Obstetrics & Gynecology and Reproductive Biology, 2014Co-Authors: Rui Miguel Costa, Stuart BrodyAbstract:Abstract Objective Given that adiposity is related to poorer female sexual function, among many other health problems, the present study aimed at testing the hypothesis that larger waist circumference, an index of subcutaneous and abdominal fat mass, is associated with lack of specifically vaginal Orgasm. Study design One hundred and twenty Portuguese women of reproductive age had their waist measured and reported their past month frequency of penile–vaginal intercourse (PVI), vaginal Orgasm, Orgasm from clitoral masturbation during PVI, non-coital partnered sex (in the absence of same-day PVI), non-coital partnered sex Orgasm (regardless of same-day PVI), masturbation, and masturbation Orgasm. Results In both simple and partial correlations (controlling for age, social desirability responding, relationship status, and cohabitation status), larger waist circumference was associated with lack of any vaginal Orgasm and with having masturbated in the past month. In a multiple regression, larger waist circumference was independently predicted by lesser frequency of vaginal Orgasm, greater frequency of masturbation, and older age. Conclusion Abdominal fat mass appears to be adversely associated with lesser capacity for vaginal Orgasm, but not for Orgasms from other sexual activities. Results are discussed in the context of vaginal Orgasm being relatively more contingent on situations of increased fitness in both partners.

women who prefer longer penises are more likely to have vaginal Orgasms but not clitoral Orgasms implications for an evolutionary theory of vaginal Orgasm
The Journal of Sexual Medicine, 2012Co-Authors: Rui Miguel Costa, Geoffrey P. Miller, Stuart BrodyAbstract:Introduction. Research indicates that (i) women's Orgasm during penile-vaginal intercourse (PVI) is influenced by fitness-related male partner characteristics, (ii) penis size is important for many women, and (iii) preference for a longer penis is associated with greater vaginal Orgasm consistency (triggered by PVI without concurrent clitoral masturbation). Aims. To test the hypothesis that vaginal Orgasm frequency is associated with women's reporting that a longer than average penis is more likely to provoke their PVI Orgasm. Method. Three hundred twenty-three women reported in an online survey their past month frequency of various sexual behaviors (including PVI, vaginal Orgasm, and clitoral Orgasm), the effects of a longer than average penis on likelihood of Orgasm from PVI, and the importance they attributed to PVI and to noncoital sex. Main Outcome Measures. Univariate analyses of covariance with dependent variables being frequencies of various sexual behaviors and types of Orgasm and with independent variable being women reporting vs. not reporting that a longer than average penis is important for their Orgasm from PVI. Results. Likelihood of Orgasm with a longer penis was related to greater vaginal Orgasm frequency but unrelated to frequencies of other sexual behaviors, including clitoral Orgasm. In binary logistic regression, likelihood of Orgasm with a longer penis was related to greater importance attributed to PVI and lesser importance attributed to noncoital sex. Conclusions. Women who prefer deeper penile-vaginal stimulation are more likely to have vaginal Orgasm, consis- tent with vaginal Orgasm evolving as part of a female mate choice system favoring somewhat larger than average penises. Future research could extend the findings by overcoming limitations related to more precise measurement of penis length (to the pubis and pressed close to the pubic bone) and girth, and large representative samples. Future experimental research might assess to what extent different penis sizes influence women's satisfaction and likelihood of vaginal Orgasm. Costa RM, Miller GF, and Brody B.

anxious and avoidant attachment vibrator use anal sex and impaired vaginal Orgasm
The Journal of Sexual Medicine, 2011Co-Authors: Rui Miguel Costa, Stuart BrodyAbstract:ABSTRACT Introduction Disturbances in intimate relationships are among the risk factors for female sexual dysfunction. Insecure styles of anxious attachment (preoccupations about abandonment) and avoidant attachment (avoidance of closeness in relationships) are robustly associated with sexual problems, relationship difficulties, and several indices of poorer physical and mental health. Similar indices of poorer sexual, relationship, and health functioning are associated with impairment of Orgasm triggered by penile‐vaginal stimulation (vaginal Orgasm), but unrelated or related to greater frequency of other sexual behaviors. However, research examining the differential association of sexual activities with insecure attachment styles has been lacking. Aims The aim of this study was to test the hypotheses that insecure attachment styles are associated with lesser vaginal Orgasm consistency, and are unrelated or directly related to greater frequency of other sexual behaviors. Method Seventy coitally experienced women recruited at a Scottish university completed the Revised Experience in Close Relationships scale, and reported their frequency of various sexual behaviors (and corresponding Orgasms) in a recent representative month. Main Outcome Measures The main outcome measures for this study are multivariate correlations of various sexual activities with insecure attachment styles, age, and social desirability response bias. Results Anxious attachment was associated with lesser vaginal Orgasm consistency, but with higher frequency of vibrator and anal sex Orgasms. Avoidant attachment was associated with higher frequency of vibrator Orgasms. Neither anxious nor avoidant attachment was associated with lifetime number of penile‐vaginal intercourse partners. Conclusions The results provide evidence that inability to attain a vaginal Orgasm is associated with anxious attachment, among other indices of poorer mental health and relatedness. Vaginal Orgasm might be the relevant sexual activity for the maintenance of a secure attachment style with a sexual partner and/or more insecurely attached women might have difficulties in attaining vaginal Orgasms and be more inclined to sexual activities characterized by more emotional and physical detachment, as part of a characterological discomfort with intimacy.

simultaneous penile vaginal intercourse Orgasm is associated with satisfaction sexual life partnership and mental health
The Journal of Sexual Medicine, 2011Co-Authors: Stuart Brody, Petr WeissAbstract:ABSTRACT Introduction Previous multivariate research found that satisfaction was associated positively with frequency of specifically penile–vaginal intercourse (PVI; as opposed to other sexual activities) as well as with vaginal Orgasm. The contribution to satisfaction of simultaneous Orgasm produced by PVI merited direct examination in a large representative sample. Aims To examine the associations of aspects of satisfaction (sexual, life, own mental health, partner relationship) with consistency of simultaneous Orgasm produced by PVI (as well as with PVI frequency and vaginal Orgasm consistency) . Methods A representative sample of Czechs (N = 1,570) aged 35–65 years completed a survey on aspects of satisfaction, PVI frequency, vaginal Orgasm consistency, and consistency of simultaneous Orgasm produced by PVI (the latter being a specially timed version of vaginal Orgasm for women). Main Outcome Measures Analysis of variance of satisfaction components (LiSat scale items) from age and the sexual behaviors. Results For both sexes, all aspects of satisfaction were associated with simultaneous PVI Orgasm consistency and with PVI frequency (except female life satisfaction). All aspects of satisfaction were also associated with vaginal Orgasm consistency. Multivariate analyses indicated that PVI frequency and simultaneous Orgasm consistency make independent contributions to the aspects of satisfaction for both sexes. Conclusions For both sexes, PVI frequency and simultaneous Orgasm produced by PVI (as well as vaginal Orgasm for women) are associated with greater life, sexual, partnership, and mental health satisfaction. Greater support for these specific aspects of sexual activity is warranted. Brody S and Weiss P.

Case Report Absence of Orgasm-induced prolactin secretion in a healthy multi-Orgasmic male subject
2020Co-Authors: Philip Haake, J Haverkamp, Norbert Leygraf, Uwe Hartmann, Manfred Schedlowski, Exton, Thc KruegerAbstract:In several studies we have recently demonstrated that Orgasm induces prolactin secretion in healthy males and females. This suggests that prolactin may form a feedback regulator of the refractory period following Orgasm. To examine this position we investigated the prolactin response of a healthy multi-Orgasmic male subject. Blood was drawn continuously during masturbation-induced Orgasm. The prolactin response of the case-subject was compared with that of nine healthy adult men with a normal refractory period. The case-subject showed no prolactin response to three Orgasms. Data from this multi-Orgasmic subject support the hypothesized role of plasma prolactin in contributing to sexual-satiation mechanisms. International Journal of Impotence Research (2002) 14, 133–135.

specificity of the neuroendocrine response to Orgasm during sexual arousal in men
Journal of Endocrinology, 2003Co-Authors: Tillmann H C Kruger, Philip Haake, Michael S. Exton, Manfred Schedlowski, Wolfram H Knapp, D Chereath, O E Janssen, Uwe HartmannAbstract:We have demonstrated that sexual activity produces transient sympathoadrenal activation and a pronounced, longlasting increase in prolactin in men and women. However, by analyzing endocrine alterations at 10-min intervals, a precise assignment of these changes to the pre-, peri- and postOrgasmic periods was not possible. Thus, the current study aimed to accurately differentiate the endocrine response to sexual arousal and Orgasm in men using an automatic blood collection technique with 2-min sampling intervals. Blood was drawn continuously before, during and after Orgasm over a total period of 40 min in 10 healthy subjects and were compared with samples obtained under a control condition. Sexual activity induced transient increases of plasma epinephrine and norepinephrine levels during Orgasm with a rapid decline thereafter. In contrast, prolactin levels increased immediately after Orgasm and remained elevated throughout the experiment. Although oxytocin was acutely increased after Orgasm, these changes were not consistent and did not reach statistical significance. Vasopressin, LH, FSH and testosterone plasma concentrations remained unaltered during sexual arousal and Orgasm. These data confirm that prolactin is secreted after Orgasm and, compared with oxytocin, seems to represent a more reliable and sustained marker for Orgasm in man. The results further 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.

coitus induced Orgasm stimulates prolactin secretion in healthy subjects
Psychoneuroendocrinology, 2001Co-Authors: Michael S. Exton, Uwe Hartmann, Tillmann H C Kruger, Markus Koch, Erika Paulson, Wolfram H Knapp, Manfred SchedlowskiAbstract:Abstract 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-induced Orgasm produced a marked elevation of plasma prolactin in both males and females. Plasma prolactin concentrations remained elevated 1 h following Orgasm. These data, together with previous evidence that masturbation-induced Orgasm produces pronounced, long-lasting increases in plasma prolactin concentrations in both males and females, suggest a role for acute prolactin alterations in modifying human sexual desire following Orgasm.

neuroendocrine and cardiovascular response to sexual arousal and Orgasm in men
Psychoneuroendocrinology, 1998Co-Authors: Tillmann H C Kruger, Michael S. Exton, Uwe Hartmann, Cornelius R Pawlak, Alexander Von Zur Muhlen, Manfred SchedlowskiAbstract:Abstract Data regarding the neuroendocrine response pattern to sexual arousal and Orgasm in man are inconsistent. In this study, ten healthy male volunteers were continuously monitored for their cardiovascular and neuroendocrine response to sexual arousal and Orgasm. Blood was continuously drawn before, during and after masturbation-induced Orgasm and analyzed for plasma concentrations of adrenaline, noradrenaline, cortisol, luteinizing hormone (LH), follicle stimulating hormone (FSH), prolactin, growth hormone (GH), β -endorphin and testosterone. Orgasm induced transient increases in heart rate, blood pressure and noradrenaline plasma levels. Prolactin plasma levels increased during Orgasm and remained elevated 30 min after Orgasm. In contrast, none of the other endocrine variables were significantly affected by sexual arousal and Orgasm. © 1998 Elsevier Science Ltd. All rights reserved.

immature defense mechanisms are associated with lesser vaginal Orgasm consistency and greater alcohol consumption before sex
The Journal of Sexual Medicine, 2010Co-Authors: Rui Miguel Costa, Stuart BrodyAbstract:INTRODUCTION: Disturbances of emotional and physical awareness can impair female sexual function. Previous research revealed that immature psychological defense mechanisms (impairing emotional awareness) are associated specifically with impaired vaginal Orgasm (Orgasm triggered solely by penile-vaginal stimulation). Alcohol consumed before sex (ACBS) might impair vaginal Orgasm or lead to avoiding the opportunity for it, but research examining immature defenses, ACBS, and specific sexual behaviors has been lacking. AIM: To test the hypothesis that greater use of immature defenses and greater ACBS are inversely associated with vaginal Orgasm consistency, but unrelated or positively correlated with greater frequency of other sexual behaviors. METHODS: Three hundred twenty-three coitally experienced women (predominantly Scottish) responded to an online survey reporting their frequency of various sexual activities (and corresponding Orgasms) and their ACBS, and completed the Defense Style Questionnaire DSQ-40. MAIN OUTCOME MEASURES: Univariate and multivariate correlations of immature defenses, ACBS, and various sexual behaviors. RESULTS: Both immature defenses and ACBS were associated with less vaginal Orgasm consistency, but unrelated or positively correlated with frequency of other sexual behaviors (including clitoral masturbation during penile-vaginal intercourse). Immature defenses were associated with more ACBS. Immature defenses explained the association between ACBS and both lack of vaginal Orgasm and greater frequency of other sexual behaviors. CONCLUSIONS: The results provide further evidence that difficulty in having a vaginal Orgasm is associated with immature defenses (and associated disturbances of sensibility), among other indicators of poorer health and relatedness. ACBS might impair vaginal Orgasm or increase the likelihood of choosing other sexual activities, but this effect might be somewhat contingent on immature defenses. Based on various empirical studies, we call for examination of the possibility that lack of vaginal Orgasm (given an adequate man) should qualify as a female sexual dysfunction.

vaginal Orgasm is associated with less use of immature psychological defense mechanisms
The Journal of Sexual Medicine, 2005Co-Authors: Stuart Brody, Rui Miguel CostaAbstract:ABSTRACT Introduction Freud implied a link between inability to have a vaginal Orgasm and psychosexual immaturity. Since Kinsey, many sexologists have asserted that no such link exists. However, empirical testing of the issue has been lacking. Aim The objective was to determine the relationship between different sexual behavior triggers of female Orgasm and use of immature psychological defense mechanisms. Methods Women reported their past month frequency of different sexual behaviors and corresponding Orgasm rates and completed the Defense Style Questionnaire (DSQ-40). Main Outcome Measure The association between ability to have vaginal intercourse Orgasm (versus clitoral Orgasm) and the use of DSQ-40 immature psychological defense mechanisms (associated with various psychopathologies) was examined. Results In a sample of 94 healthy Portuguese women, vaginal Orgasm (triggered solely by penile–vaginal intercourse) was associated with less use of DSQ-40 immature defenses. Vaginal Orgasm was associated with less somatization, dissociation, displacement, autistic fantasy, devaluation, and isolation of affect. Orgasm from clitoral stimulation or combined clitoral-intercourse stimulation was not associated with less use of immature defenses, and was associated with more use of some immature defenses. In one regression analysis, more masturbation and less vaginal Orgasm consistency made independent contributions to the statistical prediction of immature defenses. In another regression analysis, any use of extrinsic clitoral stimulation for intercourse Orgasm, and lack of any vaginal Orgasm, made independent contributions to the statistical prediction of immature defenses. Vaginally anOrgasmic women had immature defenses scores comparable to those of established (depression, social anxiety disorder, panic disorder, and obsessive–compulsive disorder) outpatient psychiatric groups. Results were not confounded by social desirability responding or relationship quality. Conclusions The results linking penile–vaginal Orgasm with less use of immature psychological defense mechanisms are consistent with both early psychoanalytic personality theory and recent advances in sexual physiology. Implications for diagnosis and sex therapy are noted. Brody S, and Costa RM. Vaginal Orgasm is associated with less use of immature psychological defense mechanisms.

International Journal of Impotence Research, 2002Co-Authors: Philip Haake, Michael S. Exton, J Haverkamp, M. Krämer, Norbert Leygraf, Uwe Hartmann, Manfred Schedlowski, Tillmann H.c. KruegerAbstract:In several studies we have recently demonstrated that Orgasm induces prolactin secretion in healthy males and females. This suggests that prolactin may form a feedback regulator of the refractory period following Orgasm. To examine this position we investigated the prolactin response of a healthy multi-Orgasmic male subject. Blood was drawn continuously during masturbation-induced Orgasm. The prolactin response of the case-subject was compared with that of nine healthy adult men with a normal refractory period. The case-subject showed no prolactin response to three Orgasms. Data from this multi-Orgasmic subject support the hypothesized role of plasma prolactin in contributing to sexual-satiation mechanisms.

coitus induced Orgasm stimulates prolactin secretion in healthy subjects
Psychoneuroendocrinology, 2001Co-Authors: Michael S. Exton, Uwe Hartmann, Tillmann H C Kruger, Markus Koch, Erika Paulson, Wolfram H Knapp, Manfred SchedlowskiAbstract:Abstract 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-induced Orgasm produced a marked elevation of plasma prolactin in both males and females. Plasma prolactin concentrations remained elevated 1 h following Orgasm. These data, together with previous evidence that masturbation-induced Orgasm produces pronounced, long-lasting increases in plasma prolactin concentrations in both males and females, suggest a role for acute prolactin alterations in modifying human sexual desire following Orgasm.

neuroendocrine and cardiovascular response to sexual arousal and Orgasm in men
Psychoneuroendocrinology, 1998Co-Authors: Tillmann H C Kruger, Michael S. Exton, Uwe Hartmann, Cornelius R Pawlak, Alexander Von Zur Muhlen, Manfred SchedlowskiAbstract:Abstract Data regarding the neuroendocrine response pattern to sexual arousal and Orgasm in man are inconsistent. In this study, ten healthy male volunteers were continuously monitored for their cardiovascular and neuroendocrine response to sexual arousal and Orgasm. Blood was continuously drawn before, during and after masturbation-induced Orgasm and analyzed for plasma concentrations of adrenaline, noradrenaline, cortisol, luteinizing hormone (LH), follicle stimulating hormone (FSH), prolactin, growth hormone (GH), β -endorphin and testosterone. Orgasm induced transient increases in heart rate, blood pressure and noradrenaline plasma levels. Prolactin plasma levels increased during Orgasm and remained elevated 30 min after Orgasm. In contrast, none of the other endocrine variables were significantly affected by sexual arousal and Orgasm. © 1998 Elsevier Science Ltd. All rights reserved.
