Reproductive System Reference Sheet 3: GLOSSARY Anus – The opening in the buttocks from which bowel movements come when a person goes to the bathroom. It is part of the digestive system; it gets rid of body wastes. Buttocks – The medical word for a person’s “bottom” or “rear end.” Cervix – The opening of the uterus into the vagina. Circumcision – An operation to remove the foreskin from the penis. Cowper’s Glands – Glands on either side of the urethra that make a discharge which lines the urethra when a man gets an erection, making it less acid-like to protect the sperm. Clitoris – The part of the female genitals that’s full of nerves and becomes erect. It has a glans and a shaft like the penis, but only its glans is on the out side of the body, and it’s much smaller. Discharge – Liquid. Urine and semen are kinds of discharge, but the word is usually used to describe either the normal wetness of the vagina or the abnormal wetness that may come from an infection in the penis or vagina. Duct – Tube, the fallopian tubes may be called oviducts, because they are the path for an ovum. -
ALPHA ADRENOCEPTORS and HUMAN SEXUAL FUNCTION Alan
8 1995 Elsevier Science B. V. All rights reserved. The Pharmacology of Sexual Function and Dysfunction J. Bancroft, editor 307 ALPHA ADRENOCEPTORS AND HUMAN SEXUAL FUNCTION Alan J Riley Field Place, Dunsmore, Buckinghamshire, HP22 6QH, UK Introduction Sexual functioning involves complex physiological processes which rely on the interplay of many central and peripheral neurotransmitter systems. Disturbances in any one of these systems might be associated with disturbed sexual function which, when recognised, may be alleviated by appropriate pharmacological manipulation, although at the present time this is more hypothesis than reality, The sympathetic nervous system is involved actively at various levels in the normal control of sexual responses. The effects of sympathetic activation are mediated by the release of noradrenaline from nerve terminals and the increased secretion of adrenaline from the adrenal medulla. These catecholamines selectively activate specific cellular sites in target tissues known as adrenoceptors (previously termed adrenergic receptors) to mediate responses. Almost fifty years ago, Alquist realised that tissue responses to catecholamines were mediated through two distinct types of receptors which he designated a and/? [1]. This review focuses on the involvement of a-adrenoceptors in human sexual functioning and dysfunction. Alpha adrenoceptors are located both pre- and post- synaptically and they were classified as either ar or af adrenoceptors according to location; or, being postsynaptic and az presynaptic. This classification continues to be used in some texts. However, as highly specific and selective pharmacological tools became available, this locational subclassification is found not always to be appropriate. Nowadays, classification of a-adrenoceptors is more appropriately based on pharmacological activity and additional subtypes of a-adrenoceptors have been identified by radioligand binding and molecular biological techniques [2]. -

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.

Copyright © The McGraw-Hill Companies, Inc. Permission required for reproduction or display. Introduction • The female reproductive system is more complex than the male system because it serves more purposes – Produces and delivers gametes – Provides nutrition and safe harbor for fetal development – Gives birth – Nourishes infant • Female system is more cyclic, and the hormones are secreted in a more complex sequence than the relatively steady secretion in the male 28-2 Sexual Differentiation • The two sexes indistinguishable for first 8 to 10 weeks of development • Female reproductive tract develops from the paramesonephric ducts – Not because of the positive action of any hormone – Because of the absence of testosterone and müllerian-inhibiting factor (MIF) 28-3 Reproductive Anatomy • Expected Learning Outcomes – Describe the structure of the ovary – Trace the female reproductive tract and describe the gross anatomy and histology of each organ – Identify the ligaments that support the female reproductive organs – Describe the blood supply to the female reproductive tract – Identify the external genitalia of the female – Describe the structure of the nonlactating breast 28-4 Sexual Differentiation • Without testosterone: – Causes mesonephric ducts to degenerate – Genital tubercle becomes the glans clitoris – Urogenital folds become the labia minora – Labioscrotal folds -

After a “breaking‐in” period, the pain‐to‐numbness ratio becomes favourable. As long as you protect against infection, wear padded shorts with a generous layer of chamois cream, no underwear and make regular offerings to the ingrown hair goddess, things are manageable.

Laser Doppler flowmetry was used to measure blood flow changes following topical application of DS1 (0.3 or 1.5 mg in 0.15 ml saline) into the vagina of anesthetized Wistar rats. In vivo hemodynamic parameters were measured with Millar-tip-catheter placed in the left ventricle. DS1 (1.5 mg) increased vaginal blood flow by 191 7 24, 226 7 22 and 166 7 23% of the baseline value (at 5, 15 and 30 min, respectively, after application) without affecting systemic blood pressure, heart rate and cardiac function. The increased vaginal blood flow following DS1 application returned to baseline between 45 and 60 min. Thus, topical application of nitric oxide donors such as DS1 may be useful for the treatment of female sexual dysfunction that develops due to an impairment of local blood flow supply to the vaginal tissue.

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. -
Comparative Morphology of the Penis and Clitoris in Four Species of Moles
RESEARCH ARTICLE Comparative Morphology of the Penis and Clitoris in Four Species of Moles (Talpidae) ADRIANE WATKINS SINCLAIR1∗, STEPHEN GLICKMAN2, KENNETH CATANIA3, AKIO SHINOHARA4, LAWRENCE BASKIN1, 1 AND GERALD R. CUNHA 1Department of Urology, University of California San Francisco, San Francisco, California 2Departments of Psychology and Integrative Biology, University of California, Berkeley, California 3Department of Biological Sciences, Vanderbilt University, Nashville, Tennessee 4Frontier Science Research Center, University of Miyazaki, Kihara, Japan ABSTRACT The penile and clitoral anatomy of four species of Talpid moles (broad-footed, star-nosed, hairy- tailed, and Japanese shrew moles) were investigated to define penile and clitoral anatomy and to examine the relationship of the clitoral anatomy with the presence or absence of ovotestes. The ovotestis contains ovarian tissue and glandular tissue resembling fetal testicular tissue and can produce androgens. The ovotestis is present in star-nosed and hairy-tailed moles, but not in broad-footed and Japanese shrew moles. Using histology, three-dimensional reconstruction, and morphometric analysis, sexual dimorphism was examined with regard to a nine feature mascu- line trait score that included perineal appendage length (prepuce), anogenital distance, and pres- ence/absence of bone. The presence/absence of ovotestes was discordant in all four mole species for sex differentiation features. For many sex differentiation features, discordance with ovotestes was observed in at least one mole species. The degree of concordance with ovotestes was highest for hairy-tailed moles and lowest for broad-footed moles. In relationship to phylogenetic clade, sex differentiation features also did not correlate with the similarity/divergence of the features and presence/absence of ovotestes. -
MR Imaging of Vaginal Morphology, Paravaginal Attachments and Ligaments
MR imaging of vaginal morph:ingynious 05/06/15 10:09 Pagina 53 Original article MR imaging of vaginal morphology, paravaginal attachments and ligaments. 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). -
Birth Cont R Ol Fact Sheet
VAGINAL RING FACT SHEET What is the Vaginal Ring (Nuvaring®)? The Vaginal Ring is a clear, flexible, thin, plastic ring that you place in the vagina where it stays for one cycle providing a continuous low dose of 2 hormones (estrogen and progestin). It prevents pregnancy by stopping the release of an egg (ovulation), thickening the cervical fluid, and changing the lining of the uterus. How effective is the Vaginal Ring? The ring is a very effective method of birth control. The ring is about 93% effective at preventing pregnancy in typical use, which means that around 7 out of 100 people who use it as their only form of birth control will get pregnant in one year. With consistent and correct use as described in this fact sheet, it can be over 99% effective. How can I get the Vaginal Ring? You can visit a clinic to get the ring or a prescription for it and talk with a healthcare provider about whether the ring is right for you. Advantages of the Vaginal Ring Disadvantages of the Vaginal Ring Periods may be more predictable/regular and lighter Must remember to remove and replace the ring once a Less period cramping month Decreased symptoms of Premenstrual Syndrome Some users may experience mild side effects such as: (PMS) and perimenopause spotting, nausea, breast tenderness, headaches, or Can be used to skip or shorten your periods dizziness (usually these improve in the first few months Less anemia/iron deficiency caused by heavy periods of use) Does not affect your ability to get pregnant in the Possibility of high blood pressure
