Orgasm is associated with different changes: (1) somatic: the peak of oxytocin contributes to relaxation of the musculature, lowering blood pressure and heart beat, reducing the frequency of breathing, leading to an overall sense of physical relaxation; (2) emotional affective: oxytocin also mediates a sense of contentment, further accentuated ...

They assert that they have identified "[t]he first objective and quantitative measure that has a strong correspondence with the subjective experience that orgasm ultimately is" and state that the measure of contractions that occur at a frequency of 8–13 Hz is specific to orgasm.
With these evolutionary considerations in mind, it should come as no surprise that many men achieve orgasm both reliably and (relative to women) indiscriminately, and it should be similarly unsurprising that many women have a large number of contingent factors that influence the frequency and quality of their orgasms (Gallup et al., 2014 ...

While they may sound like creatures from Jurassic Park the three vagina types, teleclitoridiennes, mesoclitoridiennes and paraclitoridiennes predicts almost perfectly which women can orgasm from penetration and which cannot. Knowledge of vagina types can be a way to tailor the sexual experience uniquely to your partner and give her the first orgasm she has ever had.
The suggested ejaculation frequency (masturbation) is: 5-6 times per week for teenagers of age 16-19. 3-4 times per week for young men of age 20-25. 2-3 times per week for young men of age 25-30. 1-2 times per week for men of age 30-45, no more than 1 time per week for men after 45. The intercourse often produces a powerful orgasm that ...

Genes affect orgasm frequency. According to the first genetic study of the female orgasm, up to 45 per cent of the variation in women’s ability to have them could be down to genes.
The role of female orgasm, which plays no obvious role in human reproduction, has intrigued scholars as far back as Aristotle. Numerous theories have tried to explain the origins of the trait, but ...
Mainly because no one else had ever done so, he mapped what happened in the brain during these moments of ecstasy. Read More. Music performance as an experimental approach to hyperscanning studies. A, Basson R, Luria M. Keeping this foremost in mind, Pavlicev and Wagner then looked at other mammals. Oxytocin and analgesia: Future trends. The researchers examined many species of mammals and proposed that orgasm in women evolved from an ancient trait that once played a key role in reproduction. Like male nipples, they persist simply because there is no good reason to get rid of them. Alternatively, more indirect pathways might be involved, as would be the case if spontaneous muscle contractions themselves caused systemic neurochemical changes, perhaps via ascending inputs from stretch-receptor stimulation Ferguson, ; Odent, Directionality in hyperbrain networks discriminates between leaders and followers in guitar duets. Random House Digital. L, Schiff S. This insight enabled us to trace the evolution of the trait across species. A, Makinson C. In the s, Helen Singer Kaplan added the category of desire to the cycle, which she argued precedes sexual excitation. Sexual auras: Predominance of epileptic activity within the mesial temporal lobe. Importantly, the same multicausal conditions for evaluation of sexual partners are not only contingent upon orgasm having occurred but also take place over the entirety of sexual interaction, as well as before initiating sexual activity. The lower- and upper-bound estimates for expected offspring also differ. Rich-club organization of the human connectome. Social Cognition. Archived from the original on September 28, Shelley, in this poem, associates orgasm with death when he writes "the death which lovers love". Sexuality Now: Embracing Diversity. London, A, et al. Tantra, Spirituality, and Sex. Attention and emotional responses to sexual stimuli and their relationship to sexual desire. In the following sections, I will describe potential factors influencing orgasms as variable-threshold systems, considering both proximate mechanisms and evolutionary selective pressures. This multimodal informational synergy may not only provide clearer consciousness of percepts relating to sexual stimulation but may also provide synergistically greater entrainment effects. The evolution of ovulation. A secondary purpose was to understand and assess women's experiences of exercise-induced sexual pleasure EISP Interview with author and sex educator Rebecca Chalker". Do orgasms give women feedback about mate choice? The study concluded that a "vaginal orgasm was associated with less somatization, dissociation, displacement, autistic fantasy, devaluation, and isolation of affect. Obstetrics and Gynecology Clinics of North America. Retrieved October 30, Retrieved March 2, The Biological Bulletin. Studies show that men and women who have intercourse with their partners have greater satisfaction with their mental health. Having used MRI technology which enabled her to note a direct relationship between the legs or roots of the clitoris and the erectile tissue of the "clitoral bulbs" and corpora, and the distal urethra and vagina, she stated that the vaginal wall is the clitoris; that lifting the skin off the vagina on the side walls reveals the bulbs of the clitoris—triangular, crescental masses of erectile tissue. Canadian Guide to Prostate Cancer. D, Thompson W. Vision Research. Over the last four decades, scientists have come up with a variety of theories, arguing, for example, that orgasm encourages women to have sex and, therefore, reproduce, or that it leads women to favor stronger and healthier men, maximizing their offspring's chances of survival. T, Cholakians A.
The optimal ejaculation frequency is dependable on age, exercise and sexual potential. There is a natural ejaculation frequency that balances the testosterone levels in the body. Too much testosterone and enzyme 5-alpha reductase will produce too much dihydrotestosterone DHT in the pelvic area. The result is called Pelvic Congestion and produces pains and cramps in the pelvic area and lower body. It also increases the chance of heart attack for the senior men. Too much testosterone in the body will activate the Negative Feedback Loop of the hypothalamic-pituitary-testicular function to slow down the endocrine function. Over-Masturbation or Over-Ejaculation will fully discharge the bioelectric energy in the Central Nervous System CNS , which controls the hypothalamic-pituitary-testicular functioning. When the CNS bioelectric level is too low, the endocrine function will slow down. To live longer and healthier, one has to know how to twist your endocrine function and regulate the ejaculation frequency. The natural ejaculation frequency is a rhythmic cycle of the endocrine function. Tonic foods and herbs full of plant and animal hormones or hormone release agents can increase the hormone levels, enabling the possibility of a safely increased ejaculation frequency. Cases — Forum Articles Search. The suggested ejaculation frequency masturbation is: times per week for teenagers of age The intercourse often produces a powerful orgasm that stimulates the pituitary function.

These reports continue to be cited. There is some debate whether certain types of sexual sensations should be accurately classified as orgasms, including female orgasms caused by G-spot stimulation alone, and the demonstration of extended or continuous orgasms lasting several minutes or even an hour. By comparison, women are spontaneous ovulators who produce eggs monthly, independent of sexual intercourse. The hippocampus participates in a pharmacological rat model of absence seizures. However, the numbers changed her mind. In men, the most common way of achieving orgasm is by physical sexual stimulation of the penis. Although this might seem inconsistent with increased partner discriminability, multi-orgasms could potentially enhance discrimination by increasing the discrepancies between more and less rewarding sexual experiences. Chapter "Nervous system" in Russian Abram Svyadoshch. Spindle activity is commonly interpreted as a marker of reactivation of hippocampal-based memories Andrade et al. Andrology Allergy Endocrinology Psychiatry. Personality and Individual Differences. M, Levin R. R, Nieuwenburg A, Kortekaas R. This anatomical change made it less likely that the clitoris receives adequate stimulation during intercourse to lead to the neuro-endocrine reflex known in humans as orgasm. Our Sexuality. In consensual BDSM play, forced orgasm may be practised to exercise orgasm control. Studies show that people with kids living at home tend to have more money and are more highly educated and in better health. There is some research suggesting that greater resting heart rate variability is associated with orgasms through penile-vaginal intercourse without additional simultaneous clitoral stimulation. Effects of gender and relationship context in audio narratives on genital and subjective sexual response in heterosexual women and men. Such an experience of sensate focusing and altered self-processing may be most appropriately referred to as a kind of trance state. Sexual reward in male rats: Effects of sexual experience on conditioned place preferences associated with ejaculation and intromissions. Doing it … wild? Archived from the original on November 2, And you don't have to act like bunnies to get the benefit; a study of 30, Americans over four decades found that sex at least once a week was enough to make people happy. Psychological Science. However, these methods would be unsuitable for falsification, because their poor temporal resolution would make it difficult to interpret null findings.

Retrieved August 6, We partially overcome these limitations by biasing the degree to which different representations are active within conscious experience i. For women, however, there is no clear tie between orgasm and reproduction, Frederick said. The G spot is a small region in the vagina that, if stimulated, can produce wildly intense orgasms — or so the popular claim goes. Although entrainment-related attention may be of a highly concentrated variety, it is also possible that more diffusely focused attention may produce maximal pleasure in some individuals. Wikimedia Commons Wikiquote. Opiate-induced molecular and cellular plasticity of ventral tegmental area and locus coeruleus catecholamine neurons. The Journal of Pharmacology and Experimental Therapeutics. Massachusetts, United States: Thomas. If female orgasm, by causing a hormonal surge, helped induce ovulation, this means it once played a direct role in reproduction. Journal of Neuroscience Methods. Feeling sexual pleasure, a woman decides to stand by her man; meanwhile, "the feeling of efficacy" a man gets when he elicits the female orgasm becomes "a potential strong reinforcement for the man," he said, much in line with those who argue in favor of pair-bonding. The truth is that both are sexual and both are reproductive. It has also been shown that oxytocin is produced when a man or woman's nipples are stimulated and become erect. Weak-to-moderate support for entrainment could be obtained if music, dance, or some other rhythmic practice enhanced sexual and orgasmic functioning. Komisaruk and Whipple discovered the power of the female orgasm. D, Ulbert I, Schroeder C. R, Janssen E, Heiman J. Journal of Neuroendocrinology. Archives Italiennes De Biologie. Neuroscience and Biobehavioral Reviews. Textbook of biological psychiatry. Anorgasmia is significantly more common in women than in men,   which has been attributed to the lack of sex education with regard to women's bodies, especially in sex-negative cultures, such as clitoral stimulation usually being key for women to orgasm. Greenberg, Clint E. Attention and emotional responses to sexual stimuli and their relationship to sexual desire.
CNN What is the purpose of the ever-elusive female orgasm? Photos: Hollywood's steamiest sex scenes. It isn't the first movie with risque scenes that had moviegoers titillated. Hide Caption. Their initial sleepover, set to the tune of Maxwell's "Sumthin' Sumthin'," is one that'll threaten to set fire to your TV. Years later, there is still talk about hidden messages. Turns out that steamy scene wasn't as fun for the actress: "If anyone is ever planning on having sex on top of a pile of cash: don't," Robbie said in an interview with The Daily Beast. The movie, directed by Lars von Trier, was split into two parts and released in spring Story highlights The female orgasm may have evolved from an ancient reproductive trait The hormonal surge women experience during orgasm once stimulated ovulation, research suggests. In males, orgasm is invariably required for ejaculation and transfer of sperm, researchers noted in a piece published recently in the Journal of Experimental Zoology. In women, the orgasm does not contribute to reproductive success and accompanies intercourse only "unreliably," they said. So, what gives? The researchers examined many species of mammals and proposed that orgasm in women evolved from an ancient trait that once played a key role in reproduction. To discover the big O's reason for being, the researchers explored its underlying physiology and focused on the hormonal surge that women experience while in the throes of passion. Keeping this foremost in mind, Pavlicev and Wagner then looked at other mammals. Despite the enormous diversity of reproductive styles, they were able to identify core characteristics of reproduction and track how these features evolved. Read More. The evolution of ovulation. Certain species of mammals are reflex ovulators. For example, female cats produce a mature egg ready to be fertilized by sperm only when stimulated by intercourse with a male. By comparison, women are spontaneous ovulators who produce eggs monthly, independent of sexual intercourse. Looking at the distribution of these two types of ovulation across all the species of mammals, Pavlicev and Wagner inferred that male-induced ovulation must have evolved first and spontaneous ovulation later. If female orgasm, by causing a hormonal surge, helped induce ovulation, this means it once played a direct role in reproduction. Over time, though, spontaneous ovulation evolved, rendering the female orgasm unnecessary. Want better sleep, better mood and better sex? Cut calories. Looking at the evolution of female genitals, the researchers found additional evidence that orgasm once played a fundamental role in reproduction. As females moved away from reflex ovulation toward spontaneous ovulation, the clitoris -- the major source of orgasm -- moved away from the location of sexual intercourse, the vagina. All this adds up to broader implications for women, Pavlicev and Wagner suggested: The low frequency of female orgasm -- only a quarter of all women reliably achieve orgasm during intercourse -- is not an individual woman's failing or a physical impossibility but a natural consequence of evolution. Others challenged this theory. Heated views. Elisabeth Lloyd, faculty scholar at the Kinsey Institute for Research in Sex, Gender and Reproduction, found this new theory to be "an impressive piece of work," yet she also had a "quibble. Climate change is killing our sex drive, bringing down U. The researchers define orgasm completely in terms of hormonal surges, she said, but "there's a lot more to female orgasm than hormonal surges. In her own book published in , "The Case of the Female Orgasm," she examined "all 21 published theories" of female orgasm at that time -- yes, 21 -- and discovered they all basically fell into a couple of categories. The "byproduct theory" -- the one Lloyd prefers -- is based on the biological fact that males and females develop similar traits in the first two months of life as our basic body plan and tissue patterns get laid down. By contrast, the pair-bond theory, which is adaptation-based, understands female orgasm to have evolved for the purpose of strengthening the relationship between a male and a female. In other words, the pleasurable feeling of an orgasm would encourage a woman to return to the man for more. Where's my orgasm? If female orgasm is an evolutionary adaptation, then you would expect to see more orgasmic women reproducing more children and passing that trait on to their children. But that isn't the case, Lloyd explained, citing one study of more than 8, women in which the researchers found no correlation between female orgasm and the number of her offspring. Women who often reach orgasm don't necessarily have more kids than other women. Could the female orgasm still have a purpose? Because a woman's orgasm has properties that are unique -- different from a man's orgasm -- it probably has a unique, if unknown, function, he added. While Komisaruk has spent years investigating the female orgasm, his interest developed from an unlikely start.
