Physiology of Female Sexual Function and Dysfunction
International Journal of Impotence Research (2005) 17, S44–S51 & 2005 Nature Publishing Group All rights reserved 0955-9930/05 $30.00 www.nature.com/ijir Physiology of female sexual function and dysfunction JR Berman1* 1Director Female Urology and Female Sexual Medicine, Rodeo Drive Women’s Health Center, Beverly Hills, California, USA Female sexual dysfunction is age-related, progressive, and highly prevalent, affecting 30–50% of American women. While there are emotional and relational elements to female sexual function and response, female sexual dysfunction can occur secondary to medical problems and have an organic basis. This paper addresses anatomy and physiology of normal female sexual function as well as the pathophysiology of female sexual dysfunction. Although the female sexual response is inherently difficult to evaluate in the clinical setting, a variety of instruments have been developed for assessing subjective measures of sexual arousal and function. Objective measurements used in conjunction with the subjective assessment help diagnose potential physiologic/organic abnormal- ities. Therapeutic options for the treatment of female sexual dysfunction, including hormonal, and pharmacological, are also addressed. International Journal of Impotence Research (2005) 17, S44–S51. doi:10.1038/sj.ijir.3901428 Keywords: female sexual dysfunction; anatomy; physiology; pathophysiology; evaluation; treatment Incidence of female sexual dysfunction updated the definitions and classifications based upon current research and clinical practice. -

Masturbation Among Women: Associated Factors and Sexual Response in a Portuguese Community Sample

The goal of this study was to explore the (1) age at initiation and frequency of masturbation, (2) associations of masturbation with diverse variables, (3) reported reasons for masturbating and associated emotions, and (4) the relationship between frequency of masturbation and different sexual behavioral factors. A total of 3,687 women completed a web-based survey of previously pilot-tested items. The results reveal a high reported incidence of masturbation practices amongst this convenience sample of women. Ninety one percent of women, in this sample, indicated that they had masturbated at some point in their lives with 29.3% reporting having masturbated within the previous month. Masturbation behavior appears to be related to a greater sexual repertoire, more sexual fantasies, and greater reported ease in reaching sexual arousal and orgasm. Women reported a diversity of reasons for masturbation, as well as a variety of direct and indirect techniques. A minority of women reported feeling shame and guilt associated with masturbation. Early masturbation experience might be beneficial to sexual arousal and orgasm in adulthood. Further, this study demonstrates that masturbation is a positive component in the structuring of female sexuality. -
Arousing Imaginations

Kauth, (Ed.), Handbook of the Evolution of Human Sexuality, Haworth Press, Binghamton, NY, 2006, 395 pp., $50.00 (softbound), $130.00 (hardbound) Reviewed by David Puts, Ph.D. Department of Anthropology, 424 Carpenter Building, Pennsylvania State University, University Park, PA 16802. Email: [email protected] In the quarter century since Donald Symons (1979) wrote The Evolution of Human Sexuality, research in this area has flourished. Michael Kauth’s edited volume Handbook of the Evolution of Human Sexuality (co-published as Volume 18, Numbers 2/3 and 4 2006 of the Journal of Psychology & Human Sexuality) is therefore a welcome addition. Kauth assembles researchers in diverse areas of human sexuality, including heterosexual mate choice, sexual arousal and olfactory preferences, but the focus is heavily upon the evolution and development of homosexuality, with five of the book’s ten chapters centering on this topic. Given that only 2-3% of men and 1-2% of women report predominantly homosexual preferences, this focus may seem disproportionate. However, the volume is intended not to cover all aspects of human sexuality but to serve as a springboard for future research, a mission that it will undoubtedly accomplish. The scholarship in the Handbook is variable but generally good. The content is often heavy on speculation and light on evidence, which would be less concerning if authors acknowledged this more openly. Instead, the chapters of the Handbook often reify “facts” that are still quite theoretical—for example, Kauth’s statement that “physical symmetry and extravagant sexual ornamentation are ‘honest’ signals of health and genetic quality” (p. -
Thalamus and Penile Erection
International Journal of Impotence Research (2004) 16, 505–511 & 2004 Nature Publishing Group All rights reserved 0955-9930/04 $30.00 www.nature.com/ijir Thalamus and penile erection Y Temel1*, V Visser-Vandewalle1, L Ackermans1 and EAM Beuls1 1Department of Neurosurgery, University Hospital Maastricht, Maastricht, The Netherlands Penile erection is a complex neurovascular event. The neuronal system involved is often divided into a spinal (generator) and supraspinal (controller) network. Little is known about the supraspinal control. The recent finding of changes in penile erection following deep brain stimulation of the thalamus in two patients has raised the question as to what extent the thalamus is involved in erectile function. The thalamus has generally been regarded as a group of relay nuclei that served as a ‘gate’ for sexual information from the spinal cord towards higher centres. Recent evidence, however, suggests a more integrated regulatory function. Our review of the literature from 1960 until 2003 revealed 13 reports describing original data (preclinical and clinical). Various thalamic regions, varying from the midline thalamus to the posterior thalamus, have been reported to be activated during erection. The majority of the reports, however, showed that mainly the mediodorsal (MD) nucleus and the centromedian–parafascicular nucleus (Cm–Pf complex) are involved in penile erection. MD is the second largest nuclear aggregation located within the medial part of the thalamus. Anatomically, the MD is closely related to the Cm–Pf complex. The Cm–Pf complex is one of the most important relay stations in which the anterolateral spinothalamic pathway is further processed. This pathway is thought to transmit peripheral sexual sensations. -

Vasey Department: Psychology E-mail: [email protected] Office Hours: ½ hour after each class and by appointment Webpage: http://people.uleth.ca/~paul.vasey Twitter: @Vaseylab Teaching Assistant: Scott Semenyna E-mails: [email protected] Office Hours: ½ hour after each class and by appointment. Additional availability after exams will be announced. Class Time: MW 13:00-14:15 Classroom: B660 Course Description: In this class, we will examine the phenomenon of sexual orientation in an evidence-based manner. In doing so, we will employ broad inter-disciplinary and comparative perspectives. The readings reflect this approach and, as such, are highly eclectic. Some of the questions we will address in this class include: What is sexual orientation? What factors influence the development of sexual orientation identity? How is same-sex sexuality expressed in different cultures? How do different cultures react to same-sex sexuality? How prevalent are different sexual orientation? Do same-sex attracted individuals occur in all cultures? Is sexual - 1 - orientation an isolated trait or does it reliably co-occur with other characteristics? How are male and female patterns of sexual attraction and arousal expressed? Is homosexuality a recent invention? Can sexual orientation be learned and unlearned? Do biological factors influence homosexuality? Required Readings: For many of the classes, I assign sections from the following peer review article: Bailey, M.J., Vasey, P.L., Diamond, L., Breedlove, M., Vilain, E. & Epprecht, M. (2016).

Sexuality, Intimacy & Chronic Illness
FACT SHEET SEXUALITY, INTIMACY & CHRONIC ILLNESS Relationships and sexual satisfaction are important to quality of life. This is especially true for people coping with chronic illness. Sex is an act that can bring satisfaction and release. Even though ALS does not directly affect sexual function, for a person with ALS, sex may also bring pain, frustration and embarrassment. There are methods and techniques available to help people with ALS and their partners cope with their changing sex life and maintain intimacy.

For a long time, the clitoris seems to have been regarded as the principal and most obvious female sex organ, but at some point in the 19th century this focus on the clitoris disappeared in favour of the vagina. Female sexuality was increasingly associated with child-bea- ring, and the clitoris was largely obliterated from the sexual map. In 1905, however, the clitoris was offi- cially ‘‘rediscovered’’ by Sigmund Freud. Freud also put the female orgasm back under the spotlight, be- lieving there were two kinds of orgasm: clitoral and vaginal. The vaginal orgasm, in Freud’s view, was the ‘‘mature’’ and desirable kind. Since the mid 20th cen- tury researchers and activists, mainly from the Uni- ted States and Australia, have been working to gain • • rfsu • a guide to clitoral sex renewed recognition of the importance of the clitoris to female sexuality. For most girls and women, the clitoris is the most important body part in terms of sexual pleasure. Parts of the clitoris The clitoris forms part of the vulva, the external ge- nitalia of a woman. The clitoris is a piece of erectile tissue, rich in nerve endings and blood vessels, and consists of various parts. Where the inner labia meet at the top, there is a foreskin, the prepuce or clitoral hood, covering the clitoral glans or head.
