BACKGROUND The effect of orgasm on the development and shaping of partner preferences may involve a catalysis of the neurochemical mechanisms of bonding. Therefore, understanding such process is relevant for neuroscience and psychology. METHODS A systematic review was carried out using the terms Orgasm, Sexual Reward, Partner Preference, Pair Bonding, Brain, Learning, Sex, Copulation. RESUL...

Please cite this article in press as: Zietsch, B. product theory of female orgasm, Animal Be The evolutionary basis of human female orgasm has been subject to furious scientific debate, which has recently intensified. Many adaptive explanations have been proposed, invoking functions from pair bonding and mate selection to sucking up sperm, but these have been attacked as being based on flawed l...

BACKGROUND An increasing awareness of the need to address sexual and orgasm experiences as part of life quality and an understanding of the great individual differences between women play roles in women's health and medical care across the specialities. Information is lacking as to how negative attitude toward self (NATS) and performance impairment (PI) are associated with sexual activity of mi...

background & aim: female sexual function (fsd) is a multifactorial phenomenon. sexual function is influenced by different personal and environmental factors. this study aimed to evaluate fsd and its contributing factors using female sexual function index (fsfi). methods:this descriptive cross-sectional study was conducted on 264 women referring to 11 health centers of sabzevar, iran during octo...

An orgasm in the human female is a variable, transient peak sensation of intense pleasure, creating an altered state of consciousness, usually with an initiation accompanied by involuntary, rhythmic contractions of the pelvic striated circumvaginal musculature, often with concomitant uterine and anal contractions, and myotonia that resolves the sexually induced vasocongestion and myotonia, gene...

INTRODUCTION Female genital mutilation/cutting (FGM/C) violates human rights. FGM/C women's sexuality is not well known and often it is neglected by gynecologists, urologists, and sexologists. In mutilated/cut women, some fundamental structures for orgasm have not been excised. AIM The aim of this report is to describe and analyze the results of four investigations on sexual functioning in di...

INTRODUCTION The physiology and anatomy of female sexual function are poorly understood. The differences in sexual function among women may be partly attributed to anatomical factors. AIM The purpose of this study was to use ultrasonography to evaluate the anatomical variability of the urethrovaginal space in women with and without vaginal orgasm. METHODS Twenty healthy, neurologically inta...

The evolutionary significance of the female orgasm is unclear. Adaptationist accounts seek to ascribe a positive fitness benefit to females that achieve orgasm during vaginal intercourse, spawning theories that propose the female orgasm is an adaptation to bipedalism, communal life, pair-bond formation, insemination efficiency, and mate quality assessment, among others (reviewed in Lloyd 2005)....
