“…Levin, 2003) and remains controversial specifically because of numerous failures to determine its existence as a ‘female prostate’, much less the ability of all women to find it, stimulate it, and have it induce orgasm (e.g. Kilchevsky, Vardi, Lowenstein, and Gruenwald, 2012; Pan, Leung, Shah, & Kilchevsky, 2015). A twin study by Burri, Cherkas, and Spector (2010) was one of the most glaring.…”

BackgroundThe nature of a woman’s orgasm has been a source of scientific, political, and cultural debate for over a century. Since the Victorian era, the pendulum has swung from the vagina to the clitoris, and to some extent back again, with the current debate stuck over whether internal sensory structures exist in the vagina that could account for orgasms based largely on their stimulation, or whether stimulation of the external glans clitoris is always necessary for orgasm.MethodWe review the history of the clitoral versus vaginal orgasm debate as it has evolved with conflicting ideas and data from psychiatry and psychoanalysis, epidemiology, evolutionary theory, feminist political theory, physiology, and finally neuroscience.ResultsA new synthesis is presented that acknowledges the enormous potential women have to experience orgasms from one or more sources of sensory input, including the external clitoral glans, internal region around the “G-spot” that corresponds to the internal clitoral bulbs, the cervix, as well as sensory stimulation of non-genital areas such as the nipples.ConclusionsWith experience, stimulation of one or all of these triggering zones are integrated into a “whole” set of sensory inputs, movements, body positions, autonomic arousal, and partner- and contextual-related cues, that reliably induces pleasure and orgasm during masturbation and copulation. The process of integration is iterative and can change across the lifespan with new experiences of orgasm.

“…The third consideration for female orgasm is the proposed Grafenberg or G‐spot. Although the erogenous area in the anterior wall of the vagina has been referenced since the 1st century, the contemporary understanding of its existence is largely based on anecdotal evidence from the 1950s (Pan et al, ). Cadaveric dissections do not consistently support the existence of the G‐spot (Pan et al, ).…”

“…However, histological studies using anterior vaginal wall biopsies in 32 female patients found richer small‐nerve‐fiber innervation and microvessel density in the distal third of the anterior vaginal wall (Li et al, ). During sexual stimulation, the clitoris tucks down closer to the anterior vaginal wall, which could explain why the anterior vaginal wall, in close proximity to the nerve‐rich areas of the clitoris, becomes highly sensitive during sex (Pan et al, ). It is clear that this “one size fits all” explanation of female pelvic anatomy is disputed (Hines and Kilchevsky, ).…”

Anatomic variation and orgasm: Could variations in anatomy explain differences in orgasmic success?

Though the public consciousness is typically focused on factors such as psychology, penis size, and the presence of the "G-spot," there are other anatomical and neuro-anatomic differences that could play an equal, or more important, role in the frequency and intensity of orgasms. Discovering these variations could direct further medical or procedural management to improve sexual satisfaction. The aim of this study is to review the available literature of anatomical sexual variation and to explain why this variation may predispose some patients toward a particular sexual experience. In this review, we explored the available literature on sexual anatomy and neuro-anatomy. We used PubMed and OVID Medline for search terms, including orgasm, penile size variation, clitoral variation, Grafenberg spot, and benefits of orgasm. First we review the basic anatomy and innervation of the reproductive organs. Then we describe several anatomical variations that likely play a superior role to popular known variation (penis size, presence of g-spot, etc). For males, the delicate play between the parasympathetic and sympathetic nervous systems is vital to achieve orgasm. For females, the autonomic component is more complex. The clitoris is the primary anatomical feature for female orgasm, including its migration toward the anterior vaginal wall. In conclusions, orgasms are complex phenomena involving psychological, physiological, and anatomic variation. While these variations predispose people to certain sexual function, future research should explore how to surgically or medically alter these. Clin.

Human semen contains spermatozoa secreted by the testes and a mixture of components produced by the bulbo-urethral and Littre (paraurethral) glands, prostate, seminal vesicles, ampulla, and epididymis. Ejaculation is used as a synonym for the external ejection of semen, but it comprises two phases: emission and expulsion. As semen collects in the prostatic urethra, the rapid preorgasmic distension of the urethral bulb is pathognomonic of impeding orgasm, and the man experiences a sensation that ejaculation is inevitable (in women, emission is the only phase of orgasm). The semen is propelled along the penile urethra mainly by the bulbocavernosus muscle. With Kegel exercises, it is possible to train the perineal muscles. Immediately after the expulsion phase the male enters a refractory period, a recovery time during which further orgasm or ejaculation is physiologically impossible. Age affects the recovery time: as a man grows older, the refractory period increases. Sexual medicine experts consider premature ejaculation only in the case of vaginal intercourse, but vaginal orgasm has no scientific basis, so the duration of intercourse is not important for a woman's orgasm. The key to female orgasm are the female erectile organs; vaginal orgasm, G-spot, G-spot amplification, clitoral bulbs, clitoris-urethra-vaginal complex, internal clitoris and female ejaculation are terms without scientific basis. Female sexual dysfunctions are popular because they are based on something that does not exist, i.e. the vaginal orgasm. The physiology of ejaculation and orgasm is not impaired in premature ejaculation: it is not a disease, and non-coital sexual acts after male ejaculation can be used to produce orgasm in women. Teenagers and men can understand their sexual responses by masturbation and learn ejaculatory control with the stop-start method and the squeeze technique. Premature ejaculation must not be classified as a male sexual dysfunction. It has become the center of a multimillion dollar business: is premature ejaculation-and female sexual dysfunction-an illness constructed by sexual medicine experts under the influence of drug companies?
