Normal features VITTORIO PILONI Iniziativa Medica, Diagnostic Imaging Centre, Monselice (Padova), Italy Abstract: Aim: To define the MR appearance of the intact vaginal and paravaginal anatomy. Method: the pelvic MR examinations achieved with external coil of 25 nulliparous women (group A), mean age 31.3 range 28-35 years without pelvic floor dysfunctions, were compared with those of 8 women who had cesarean delivery (group B), mean age 34.1 range 31-40 years, for evidence of (a) vaginal morphology, length and axis inclination; (b) perineal body’s position with respect to the hymen plane; and (c) visibility of paravaginal attachments and lig- aments. Results: in both groups, axial MR images showed that the upper vagina had an horizontal, linear shape in over 91%; the middle vagi- na an H-shape or W-shape in 74% and 26%, respectively; and the lower vagina a U-shape in 82% of cases. Vaginal length, axis inclination and distance of perineal body to the hymen were not significantly different between the two groups (mean ± SD 77.3 ± 3.2 mm vs 74.3 ± 5.2 mm; 70.1 ± 4.8 degrees vs 74.04 ± 1.6 degrees; and +3.2 ± 2.4 mm vs + 2.4 ± 1.8 mm, in group A and B, respectively, P > 0.05). Overall, the lower third vaginal morphology was the less easily identifiable structure (visibility score, 2); the uterosacral ligaments and the parau- rethral ligaments were the most frequently depicted attachments (visibility score, 3 and 4, respectively); the distance of the perineal body to the hymen was the most consistent reference landmark (mean +3 mm, range -2 to + 5 mm, visibility score 4).

  • The Mythical G-Spot: Past, Present and Future by Dr
    Global Journal of Medical research: E Gynecology and Obstetrics Volume 14 Issue 2 Version 1.0 Year 2014 Type: Double Blind Peer Reviewed International Research Journal Publisher: Global Journals Inc. (USA) Online ISSN: 2249-4618 & Print ISSN: 0975-5888 The Mythical G-Spot: Past, Present and Future By Dr. Franklin J. Espitia De La Hoz & Dra. Lilian Orozco Santiago Universidad Militar Nueva Granada, Colombia Summary- The so-called point Gräfenberg popularly known as "G-spot" corresponds to a vaginal area 1-2 cm wide, behind the pubis in intimate relationship with the anterior vaginal wall and around the urethra (complex clitoral) that when the woman is aroused becomes more sensitive than the rest of the vagina. Some women report that it is an erogenous area which, once stimulated, can lead to strong sexual arousal, intense orgasms and female ejaculation. Although the G-spot has been studied since the 40s, disagreement persists regarding the translation, localization and its existence as a distinct structure. Objective: Understand the operation and establish the anatomical points where the point G from embryology to adulthood. Methodology: A literature search in the electronic databases PubMed, Ovid, Elsevier, Interscience, EBSCO, Scopus, SciELO was performed. Results: descriptive articles and observational studies were reviewed which showed a significant number of patients. Conclusion: Sexual pleasure is a right we all have, and women must find a way to feel or experience orgasm as a possible experience of their sexuality, which necessitates effective stimulation.

  • Sexual Anatomy and Function in Women with and Without Genital Mutilation: a Cross-Sectional Study
    FEMALE SEXUAL FUNCTION Sexual Anatomy and Function in Women With and Without Genital Mutilation: A Cross-Sectional Study Jasmine Abdulcadir, MD,1,2 Diomidis Botsikas, MD,1,3 Mylène Bolmont, PhD Candidate,4 Aline Bilancioni, RN,1 Dahila Amal Djema, MD,3 Francesco Bianchi Demicheli, MD,1 Michal Yaron, MD,1 and Patrick Petignat, MD1 ABSTRACT Introduction: Female genital mutilation (FGM), the partial or total removal of the external genitalia for non-medical reasons, can affect female sexuality. However, only few studies are available, and these have significant methodologic limitations. Aim: To understand the impact of FGM on the anatomy of the clitoris and bulbs using magnetic resonance imaging and on sexuality using psychometric instruments and to study whether differences in anatomy after FGM correlate with differences in sexual function, desire, and body image. Methods: A cross-sectional study on sexual function and sexual anatomy was performed in women with and without FGM. Fifteen women with FGM involving cutting of the clitoris and 15 uncut women as a control group matched by age and parity were prospectively recruited. Participants underwent pelvic magnetic resonance imaging with vaginal opacification by ultrasound gel and completed validated questionnaires on desire (Sexual Desire Inventory), body image (Questionnaire d’Image Corporelle [Body Image Satisfaction Scale]), and sexual function (Female Sexual Function Index). Main Outcome Measures: Primary outcomes were clitoral and bulbar measurements on magnetic resonance images. Secondary outcomes were sexual function, desire, and body image scores. Results: Women with FGM did not have significantly decreased clitoral glans width and body length but did have significantly smaller volume of the clitoris plus bulbs.

  • Skin Damage from Chronic Irritation Or Scratching
    Skin Damage from Chronic Irritation or Scratching Chronic irritation and scratching can cause skin damage to the vulva. Confusingly, this may be called many different things like Eczema, Lichen Simplex Chronicus (LSC), Chronic Dermatitis or Squamous Cell Hyperplasia. Some of these diagnoses require that a biopsy of the vulva has been performed; others are based just on clinical opinion after history and physical examination. Many things can trigger irritation of the vulva. For instance, scratching alone can lead to changes on the vulva that can be seen on physical exam or self-inspection. Often the original event that precipitated irritation and itching is unknown. Sometimes it is a vaginal infection, sometimes it is a contact irritant and sometimes it is a nervous itch. Regardless, the skin becomes irritated and inflamed, therefore beginning the “Scratch-Itch” cycle. Once this cycle is perpetuated, it is difficult for the vulvar skin to heal and the changes persist. When a biopsy is performed, it can greatly assist your practitioner in finding a diagnosis that can lead to successful treatment. Lichen simplex chronicus (LSC) and Squmous Cell Hyperplasia are 2 diagnoses that can be rendered after a skin biopsy. These are essentially similar entities and are defined as abnormal thickening of the skin of the vulva. Two thirds of patients who develop this condition are premenopausal. Moisture, chronic scratching, scrubbing, allergens, and medications may cause variations in the appearance of the lesions. The size of the lesions ranges from small to large, red to white, excoriated to eroded, and most frequently involve certain areas of the vulva like the hood of the clitoris, the labia majora, the interlabial sulcus (space between major and minor lips) outer aspect of the labia minora, and the perineal body (space between anus and vaginal opening).

  • Genital Variation
    Genital Variation People’s genitals are as unique as snowflakes! No two are alike... Our bodies, including our genitals, come in a variety of shapes, colors, and sizes. No two are exactly alike. Same bits & pieces, composed differently Did you know all human fetuses start out “female” unless hormones direct them differently? That’s why a fully-formed penis shares many characteristics with a clitoris, including a darker “underskin” and a thin “ridge” or seam” which runs from scrotum to anus. Basically, everyone’s sexual anatomy is arranged to accomplish the same few tasks: to produce steroid hormones for growth and development, to support reproduction, and to create pleasure during sex. Variations in anatomy simply reflect our unique abilities to accomplish these same tasks. Media paints an inaccurate picture The images of genitals shown in ads and in porn are commonly altered—subjected to airbrushing, makeup, fancy camera angles, photo editing and size-distorting techniques. The end result is a socially-constructed aesthetic, one which creates a false perception of conformity and reinforces a sex/gender binary. Real bodies are more interesting, varied, and nuanced.

  • Labial Hypertrophy and Asymmetry
    Labial Hypertrophy and Asymmetry What are labial hypertrophy and labial asymmetry? Labial hypertrophy is an increase in the size of one or both of the “lips” of the vagina, called the labia. Labial hypertrophy can affect the inner labia, known as the labia minora, or the outer labia, called the labia majora. When only one side of the labia is enlarged, the condition is referred to as labial asymmetry. There is no definition of “normal” labia size, but sometimes the labia minora or majora are larger than another persons How is labial hypertrophy or asymmetry or larger on one side. treated?

  • Vulvas and Vaginas
    Vulvas and Vaginas 2 An Introduction to: Vulvas and Vaginas What is a Vulva? The Vulva is the entire external female genitalia – inner and outer labia, clitoris, clitoral hood, mons, vestibule and urethral and vagina openings. This part of the anatomy gets called lots of funny names: vajayjay, muff, coochie, crotch, “down there,” and often it gets confused with the vagina – the stretchable passage that leads to the cervix and uterus and is involved in menstruation, intercourse, pregnancy and delivery. Because the vulva and vagina are hidden, they can seem mysterious, confusing and even shameful. Let’s eliminate the mystery. Your vulva and vagina can be the source of much pleasure and it is a good idea to get to know them and all their wonders. Don’t be shy! Get to know your body! Look at your Vulva! Stand or sit over a mirror and take a good look. Examining the Vulva is healthy; it gets you familiar and comfortable with your unique body and all its parts. Labia: The word labia means lips in Latin. The outer labia are two folds of skin and fatty tissue which are the colour of your skin or a bit darker. They are covered in pubic hair after puberty and surround the rest of the vulva. They can be large or small, short or long and, like breasts, can be two different sizes. They swell during arousal and are often very sensitive. The inner labia are also sensitive and swell during arousal. These are the folds of skin that go from the clitoral hood to below the vaginal opening.
