In women, low sexual desire and/or sexual arousal can lead to sexual dissatisfaction and emotional distress, collectively defined as female sexual interest/arousal disorder (FSIAD). Few pharmaceutical treatment options are currently available.

Marijuana use is increasingly prevalent in the United States. Effects of marijuana use on sexual function are unclear, with contradictory reports of enhancement and detriment existing.

Previously, variable-centered analytic approaches showed positive, weak-to-moderate associations between frequency of pornography use (FPU) and problematic pornography use (PPU). However, person-centered studies are sparse in the literature, and these could provide insight into whether there are individuals who use pornography frequently and do not experience problems or whether there are individuals with comparable high-frequency use who differ on reported experiencing of negative consequences.

During sexual stimulation, some women report the discharge of a noticeable amount of fluid from the urethra, a phenomenon also called “squirting.” To date, both the nature and the origin of squirting remain controversial. In this investigation, we not only analyzed the biochemical nature of the emitted fluid, but also explored the presence of any pelvic liquid collection that could result from sexual arousal and explain a massive fluid emission.

Although several theories and treatment plans use unusual sexual fantasies (SF) as a way to identify deviancy, they seldom describe how the fantasies referred to were determined to be unusual.

On 23rd March 2020 the UK government released self-isolation guidance to reduce the risk of transmission of SARS-Cov-2. The influence such guidance has on sexual activity is not known.

Penile size continues to receive popular and empirical attention. Little is known about the process of self-measurement and whether the behaviors a man engages in to become erect for self-measurement are associated with his erect penile dimensions.

The etiological role of sleep disturbance in sexual difficulties has been largely overlooked. Research suggests that short sleep duration and poor sleep quality lead to poor female sexual response. However, prior research consists of cross-sectional studies, and the influence of sleep on sexual functioning and behavior has not been prospectively examined.

INTRODUCTION: Erectile dysfunction (ED) is a common complaint in men over 40 years of age, and prevalence rates increase throughout the aging period. Prevalence and risk factors of ED among young men have been scantly analyzed. AIM: Assessing sociodemographic and clinical characteristics of young men (defined as ≤40 years) seeking first medical help for new onset ED as their primary sexual disorder. METHODS: Complete sociodemographic and clinical data from 439 consecutive patients were analyzed. Health-significant comorbidities were scored with the Charlson Comorbidity Index (CCI). Patients completed the International Index of Erectile Function (IIEF). MAIN OUTCOME MEASURE: Descriptive statistics tested sociodemographic and clinical differences between ED patients ≤40 years and >40 years. RESULTS: New onset ED as the primary disorder was found in 114 (26%) men ≤40 years (mean [standard deviation [SD]] age: 32.4 [6.0]; range: 17-40 years). Patients ≤40 years had a lower rate of comorbid conditions (CCI = 0 in 90.4% vs. 58.3%; χ(2) , 39.12; P < 0.001), a lower mean body mass index value (P = 0.005), and a higher mean circulating total testosterone level (P = 0.005) as compared with those >40 years. Younger ED patients more frequently showed habit of cigarette smoking and use of illicit drug, as compared with older men (all P ≤ 0.02). Premature ejaculation was more comorbid in younger men, whereas Peyronie’s disease was prevalent in the older group (all P = 0.03). At IIEF, severe ED rates were found in 48.8% younger men and 40% older men, respectively (P > 0.05). Similarly, rates of mild, mild-to-moderate, and moderate ED were not significantly different between the two groups. CONCLUSIONS: This exploratory analysis showed that one in four patients seeking first medical help for new onset ED was younger than 40 years. Almost half of the young men suffered from severe ED, with comparable rates in older patients. Overall, younger men differed from older individuals in terms of both clinical and sociodemographic parameters.

INTRODUCTION: Spontaneous orgasm triggered from inside the foot has so far not been reported in medical literature. AIMS: The study aims to report orgasmic feelings in the left foot of a woman. METHODS: A woman presented with complaints of undesired orgasmic sensations originating in her left foot. In-depth interview, physical examination, sensory testing, magnetic resonance imaging (MRI-scan), electromyography (EMG), transcutaneous electrical nerve stimulation (TENS), and blockade of the left S1 dorsal root ganglion were performed. MAIN OUTCOME MEASURES: The main outcomes are description of this clinical syndrome, results of TENS application, and S1 dorsal root ganglion blockade. RESULTS: Subtle attenuation of sensory amplitudes of the left suralis, and the left medial and lateral plantar nerve tracts was found at EMG. MRI-scan disclosed no foot abnormalities. TENS at the left metatarso-phalangeal joint-III of the left foot elicited an instant orgasmic sensation that radiated from plantar toward the vagina. TENS applied to the left side of the vagina elicited an orgasm that radiated to the left foot. Diagnostic blockade of the left S1 dorsal root ganglion with 0.8 mL bupivacaine 0.25 mg attenuated the frequency and intensity of orgasmic sensation in the left foot with 50% and 80%, respectively. Additional therapeutic blockade of the same ganglion with 0.8 mL bupivacaine 0.50 mg combined with pulsed radiofrequency treatment resulted in a complete disappearance of the foot-induced orgasmic sensations. CONCLUSION: Foot orgasm syndrome (FOS) is descibed in a woman. Blockade of the left S1 dorsal root ganglion alleviated FOS. It is hypothesized that FOS, occurring 1.5 years after an intensive care emergency, was caused by partial nerve regeneration (axonotmesis), after which afferent (C-fiber) information from a small reinnervated skin area of the left foot and afferent somatic and autonomous (visceral) information from the vagina on at least S1 spinal level is misinterpreted by the brain as being solely information originating from the vagina.
