Haptic and Somesthetic Communication in Sexual Medicine

Is it time for doctors to Rx vibrators? A systematic review of pelvic floor outcomes

Introduction

Vibrators and similar devices are an underutilized treatment modality in pelvic and sexual medicine, likely because of the limited knowledge on the health benefits of their use.

Objectives

The aim of this study was to review available data regarding the effect of vibrator use on sexual function, pelvic floor function, and chronic unexplained vulvar pain.

Methods

We performed a systematic literature review of PubMed, Embase, and MEDLINE from inception to March 2021 per the PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-analyses). The search was based on the following keywords: sex toy woman, pelvic vibrator, sexual stimulation vibrator, vaginal vibrator, vibrator pelvic floor, vibrator incontinence, and vulvar pain vibrator. An overall 586 articles were identified. Studies that met inclusion criteria were reviewed: original research, sample of women, vibrator use, and application to the pelvic/genital area. Exclusion criteria included case reports, unrelated content, vibrator not applied to the pelvic/genital area, male participants, or conditions of interest not addressed. A total of 17 original studies met the criteria and were reviewed in depth.

Results

After review of the literature and identification of articles appropriate for the study, there were 8 studies surrounding sexual function, 8 on pelvic floor function (muscle strength/urinary incontinence), and 1 on vulvar pain. Among the identified studies, vibrators were considered an accepted modality to enhance a woman’s sexual experience, improve pelvic floor muscle function, and facilitate treatment of vulvar pain.

Conclusions

Vibrators are not well studied, and given the promising benefits demonstrated in the articles identified, future research efforts should be directed toward investigating their utility. Considering the potential pelvic health benefits of vibrators, their recommendation to women could be included in our pelvic floor disorder treatment armamentarium.

The Lost Penis Syndrome: A New Clinical Entity in Sexual Medicine

INTRODUCTION

The "lost penis syndrome" (LPS) is a term often used in non-clinical settings to describe the subjective perception of the loss of cutaneous and proprioceptive feelings of the male organ during vaginal penetration. Although deserving clinical attention, this syndrome did not receive any consideration in the medical literature. Notwithstanding, it represents a relatively unexceptional condition among patients in sexual medicine clinics, and it is often reported together with other sexual dysfunctions, especially delayed ejaculation, anejaculation, male anorgasmia and inability to maintain a full erection.

OBJECTIVES

To draft a new conceptual characterization of the LPS, defined as a lack of penile somesthetic sensations during sexual penetration due to various causes and leading to several sexual consequences in both partners.

METHODS

Based on an extensive literature review and physiological assumptions, the mechanisms contributing to friction during penovaginal intercourse, and their correlation to LPS, have been explored, as well as other nonanatomical factors possibly contributing to the loss of penile sensations.

RESULTS

Efficient penile erection and sensitivity, optimal vaginal lubrication and trophism contribute to penovaginal friction. Whenever one of these processes does not occur, loss of penile sensation defined as LPS can occur. Sociocultural, psychopathological and age-related (ie, couplepause) factors are also implicated in the etiology. Four types of LPS emerged from the literature review: anatomical and/or functional, behavioral, psychopathological and iatrogenic. According to the subtype, a wide variety of treatments can be employed, including PDE5i, testosterone replacement therapy and vaginal cosmetic surgery, as well as targeted therapy for concomitant sexual comorbidity.

CONCLUSION

We held up the mirror on LPS as a clinically existing multifactorial entity and provided medical features and hypotheses contributing to or causing the occurrence of LPS. In the light of a sociocultural and scientific perspective, we proposed a description and categorization of this syndrome hypothesizing its usefulness in daily clinical practice.

Do We Still Believe There Is a G-spot?

Abstract

In the field of female sexuality, the existence of the so-called “G-spot” represents a topic still anchored to anecdotes and opinions and explained using non-scientific points, as well as being overused for commercial and mediatic purposes.

Purpose of Review

The scope of this review is to give an update on the current state of information regarding the G-spot and suggesting potential future directions in the research field of this interesting, albeit controversial, aspect of human sexual physiology.

Recent Findings

From evolutionary, anatomical, and functional points of view, new evidence has rebutted the original conceptualization of the G-spot, abandoning the idea of a specific anatomical point able to produce exceptional orgasmic experiences through the stimulation of the anterior vaginal wall, the site where the G-spot is assumed to be. From a psychological perspective, only few findings to date are able to describe the psychological, behavioral, and social correlates of the pleasure experience by G-spot-induced or, better, vaginally induced orgasm (VAO).

Summary

Recent literature suggests the existence of a G-spot but specifies that, since it is not a spot, neither anatomically nor functionally, it cannot be called G, nor spot, anymore. It is indeed a functional, dynamic, and hormone-dependent area (called clitorourethrovaginal, CUV, complex), extremely individual in its development and action due to the combined influence of biological and psychological aspects, which may trigger VAO and in some particular cases also female ejaculation (FE).
