Human asexuality is generally defined as a lack of sexual attraction. We used online questionnaires to investigate reasons for masturbation, and explored and compared the contents of sexual fantasies of asexual individuals (identified using the Asexual Identification Scale) with those of sexual individuals. A total of 351 asexual participants (292 women, 59 men) and 388 sexual participants (221 women, 167 men) participated. Asexual women were significantly less likely to masturbate than sexual women, sexual men, and asexual men...

INTRODUCTION: Prostate cancer (PCa) is one of the leading causes of cancer death in men and remains one of the most diagnosed malignancies worldwide. Ongoing public health efforts continue to promote protective factors, such as diet, physical activity, and other lifestyle modifications, against PCa development. Masturbation is a nearly universal safe sexual activity that transcends societal boundaries and geography yet continues to be met with stigma and controversy in contemporary society...

OBJECTIVE: To describe patients with sexsomnia and to contrast their clinical and sleep measures with those of healthy controls and sleepwalkers. METHODS: Subjects referred for sexsomnia and for sleepwalking/night terror were interviewed, completed the Paris Arousal Disorder Severity Scale (PADSS) and were monitored one to two nights with video-polysomnography. RESULTS: Seventeen patients (70.6% male, aged 17 to 76 years) had sexsomnia, with amnestic fondling of the bed partner (n=11), complete sexual intercourse (n=8), masturbation (n=8) and spontaneous orgasm (n=1)...

BACKGROUND: The pursuit of sexual pleasure is a key motivating factor in sexual activity. Many things can stand in the way of sexual orgasms and enjoyment, particularly among women. These are essential issues of sexual well-being and gender equality. OBJECTIVE: This study presents long-term trends and determinants of female orgasms in Finland. The aim is to analyze the roles of factors such as the personal importance of orgasms, sexual desire, masturbation, clitoral and vaginal stimulation, sexual self-esteem, communication with partner, and partner's sexual techniques...

BACKGROUND: The 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. METHOD: We 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...

BACKGROUND: Previous studies have shown that personality characteristics affect sexual functioning. The aim of this exploratory study was to assess and describe the relationship between global personality traits and the stereotypical femininity and masculinity levels with the broad aspects of sexual behaviours and attitudes in the group of 97 heterosexual young adult men aged 19-39 and living in Poland. METHODS: The 'Big Five' personality traits were measured with the NEO-FFI questionnaire; stereotypical femininity and masculinity with the Bem sex role inventory (BSRI); sexual disorders with the International index of erectile function (IIEF); socio-epidemiological data, sexual behaviours and attitudes towards sexuality with a self-constructed questionnaire...

This study investigates how men who have sex with men (MSM) use chat and dating sites based on theories of stigma-related offline behavior and online self-disclosure. We hypothesize that hidden MSM (those who self-label as heterosexual or who hide their same-sex sexual attraction from family, friends, acquaintances, or a female romantic partner) differ to open MSM in how they behave on gay chat and dating sites and in offline gay venues. Drawing on a survey of 12,002 MSM, we show that hidden MSM tend to mask their identity on gay chat and dating sites while avoiding offline gay venues...

Dogs have been under strong artificial selection as a consequence of their relationship with man. Differences between breeds are evident that could be reflected in seminal characteristics. The present study was to evaluate differences in sperm head morphometry between seven well-defined breeds of dog: the British Bulldog, Chihuahua, German Shepherd, Labrador Retriever, Spanish Mastiff, Staffordshire Terrier, and Valencian Rat Hunting dog. Semen samples were obtained by masturbation and smears stained with Diff-Quik...

This work provides information on the blue fox ejaculated sperm quality needed for seminal dose calculations. Twenty semen samples, obtained by masturbation, were analyzed for kinematic and morphometric parameters by using CASA-Mot and CASA-Morph system and principal component (PC) analysis. For motility, eight kinematic parameters were evaluated, which were reduced to PC1, related to linear variables, and PC2, related to oscillatory movement. The whole population was divided into three independent subpopulations: SP1, fast cells with linear movement; SP2, slow cells and nonoscillatory motility; and SP3, medium speed cells and oscillatory movement...

Self-insertion of foreign bodies in the urethra is most commonly associated with sexual or erotic arousal of adolescents with mental health disorders. Rarely it may practiced by healthy adults for masturbation. Migration of foreign bodies used for the abovementioned purpose from the urethra to adjacent organs is a relatively uncommon urologic problem that may cause serious complications which arose tardive. Presentation includes a variety of acute or chronic symptoms that depend of the underlying complications...

REVIEW
Marcel D Waldinger
Men with post orgasmic illness syndrome (POIS) become ill rather immediately after ejaculation, whether spontaneously at night, during sexual intercourse or masturbation. Two subtypes are distinguished: primary and secondary POIS. It also occurs before or after a man has been sterilized. POIS is an invalidating most probably auto-immune disease leading to much distress in males and their partners. It is characterized by five criteria. Its symptoms are described by seven clusters. However, the manifestation of these symptoms varies from one male to the other but is relatively constant in the person himself...

Michael A Perelman
The Sexual Tipping Point(®) (STP) model is an integrated approach to the etiology, diagnosis and treatment of men with delayed ejaculation (DE), including all subtypes manifesting ejaculatory delay or absence [registered trademark owned by the MAP Educational Fund, a 501(c)(3) public charity]. A single pathogenetic pathway does not exist for sexual disorders generally and that is also true for DE specifically. Men with DE have various bio-psychosocial-behavioral & cultural predisposing, precipitating, maintaining, and contextual factors which trigger, reinforce, or worsen the probability of DE occurring...

This study was designed to analyze the sperm kinematic and morphometric subpopulations in the different fractions of the ejaculate in normozoospermic men. Ejaculates from eight normozoospermic men were collected by masturbation in three fractions after 3-5 days of sexual abstinence. Analyses of sperm motility by computer-assisted sperm analysis (CASA-Mot), and of sperm morphometry by computer-assisted sperm morphometry analysis (CASA-Morph) using fluorescence were performed. Clustering and discriminant procedures were performed to identify sperm subpopulations in the kinematic and morphometric data obtained...

PURPOSE OF REVIEW: The purpose of this review is to help further the understanding of the clinical profile of patients with sexsomnia and to better understand the spectrum of the clinical manifestations of sexsomnia. We will review the literature from the past decade on the subject and then compare it with our own clinical experience from patients who were retrospectively identified with sexsomnia at a tertiary sleep clinic over a 6-year period. RECENT FINDINGS: The prevalence of sexual behaviours in sleep remains unknown, but it seems to involve predominantly younger male adults who also frequently exhibit other non-rapid eye movement-related parasomnias...

Fetal masturbation has been described previously once in utero but only as a description of an action. Masturbation is well described in infancy and early childhood when they discover that this practice can give them pleasure. Our letter proves that it could begin in utero as a 'gratification behaviour'. We have shown this pattern clearly by using a volumetric rendering mode study. © 2016 John Wiley & Sons, Ltd.

This study used population-representative longitudinal data from the 2005-2006 and 2010-2011 waves of the National Social Life, Health and Aging Project-a probability sample of US adults aged 57-85 at baseline (N = 650 women and 620 men)-to examine the causal direction in linkages of endogenous testosterone (T) with sexual activity and relationship quality. For both genders, our autoregressive effects indicated a large amount of temporal stability, not just in individual-level attributes (T, masturbation) but also dyadic ones (partnered sex, relationship quality)-indicating that a need for more nuanced theories of relational processes...

Sexual activity before competition has been considered as a possible cause for reduced performance since ancient Greece and Rome. Recently, the hypothesis that optimal sport performance could be influenced by a variety of factors including sexual activity before competition has been investigated. However, few scientific data are available, with the exception of anecdotal reports of individual experiences. The present systematic review focused on the current scientific evidence on the effects of sexual activity on sport performance regardless of sport type...

It has been generally assumed that partner's erectile dysfunction, premature, and delayed ejaculation play a significant role in determining female sexual dysfunction (FSD). This study aimed to evaluate the role of the male partner's sexual function, as perceived by women, in determining FSD. A consecutive series of 156 heterosexual women consulting our clinic for FSD was retrospectively studied. All patients underwent a structured interview and completed the Female Sexual Function Index (FSFI). FSFI total score decreased as a function of partner's age, conflicts within the couple, relationship without cohabitation and the habit of engaging in intercourse to please the partner; FSFI total score increased as a function of frequency of intercourse, attempts to conceive and fertility-focused intercourse...
