Selected AbstractsEndocrine Aspects of Female Sexual DysfunctionTHE JOURNAL OF SEXUAL MEDICINE, Issue 1 2004Susan R. Davis MD ABSTRACT Introduction., Various endogenous hormones, including estrogen, testosterone, progesterone and prolactin, may influence female sexual function. Aim., To provide recommendations for the diagnosis and treatment of women with endocrinologic sexual difficulties. Methods., The Endocrine Aspects of Female Sexual Dysfunction Committee was part of a multidisciplinary International Consultation. It included four experts from two countries and several peer reviewers. Main Outcome Measure., Expert opinion was based on committee discussion, a comprehensive literature review and evidence-based grading of available publications. Results., The impact of hormones on female sexual function and their etiological roles in dysfunction is complex. Research data are limited as studies have been hampered by lack of precise hormonal assays and validated measures of sexual function in women. Sex steroid insufficiency is associated with urogenital atrophy and may also adversely affect central sexual thought processes. Systemic estrogen/estrogen progestin therapy alleviates climacteric symptoms but there is no evidence that this therapy specifically improves hypoactive sexual desire disorder (HSDD) in premenopausal or postmenopausal women. Exogenous testosterone has been shown in small randomized controlled trials (RCT) to improve sexual desire, arousal and sexual satisfaction in both premenopausal and postmenopausal women. However, as there is no biochemical measure that clearly identifies who to treat, use of exogenous testosterone should be considered only after other causes of HSDD have been excluded, such as depression, relationship problems and ill health. The clinical assessment of HSDD should include detailed medical, gynecologic, sexual and psychosocial history and physical examination including the external/internal genitalia. Hormonal therapy should be individualized and risks/benefits fully discussed, and all treated women should be carefully followed up and monitored for therapeutic side effects. Conclusions., There is a need for prospective, multi-institutional clinical trials to define safe and effective endocrine treatments for female sexual dysfunction.

(Theridiidae), is described from Korea. It is easily distinguished from other congeners by the structure of conductor, radix, median apophysis, and the female epigynum and internal genitalia.

Sommers PhD Abstract Little is known about the role of skin color in the forensic sexual assault examination. The purpose of this study was to determine whether anogenital injury prevalence and frequency vary by skin color in women after consensual sexual intercourse. The sample consisted of 120 healthy (63 Black, 57 White) women who underwent a forensic sexual assault examination following consensual sexual intercourse. Experienced sexual assault forensic examiners using visual inspection, colposcopy technique with digital imaging, and toluidine blue application documented the number, type, and location of anogenital injuries. Although 55% of the total sample was observed to have at least one anogenital injury of any type following consensual intercourse, the percentages significantly differed for White (68%) and Black (43%) participants (p= 0.02). When the presence of anogenital injury was analyzed by specific anatomical region, a significant difference between White and Black participants was only evident for the external genitalia (White = 56%, Black = 24%, p= .003), but not for the internal genitalia (White = 28%, Black = 19%, p= .20) or anus (White = 9%, Black = 10%, p= 0.99). A one standard deviation-unit increase in L* values (lightness) was related to a 150% to 250% increase in the odds of external genitalia injury prevalence (p < 0.001). While Black and White participants had a significantly different genital injury prevalence, dark skin color rather than race was a strong predictor for decreased injury prevalence. Sexual assault forensic examiners, therefore, may not be able to detect injury in women with dark skin as readily as women with light skin, leading to health disparities for women with dark skin. [source] External genital morphology of the ring-tailed lemur (Lemur catta): Females are naturally "masculinized"JOURNAL OF MORPHOLOGY, Issue 4 2008Christine M. Drea Abstract The extravagance and diversity of external genitalia have been well characterized in male primates; however, much less is known about sex differences or variation in female form. Our study represents a departure from traditional investigations of primate reproductive anatomy because we 1) focus on external rather than internal genitalia, 2) measure both male and female structures, and 3) examine a strepsirrhine rather than an anthropoid primate. The subjects for morphological study were 21 reproductively intact, adult ring-tailed lemurs (Lemur catta), including 10 females and 11 males, two of which (one per sex) subsequently died of natural causes and also served as specimens for gross anatomical dissection. Male external genitalia presented a typical masculine configuration, with a complex distal penile morphology. In contrast, females were unusual among mammals, presenting an enlarged, pendulous external clitoris, tunneled by the urethra. Females had a shorter anogenital distance and a larger urethral meatus than did males, but organ diameter and circumference showed no sex differences. Dissection confirmed these characterizations. Noteworthy in the male were the presence of a "levator penis" muscle and discontinuity in the corpus spongiosum along the penile shaft; noteworthy in the female were an elongated clitoral shaft and glans clitoridis. The female urethra, while incorporated within the clitoral body, was not surrounded by erectile tissue, as we detected no corpus spongiosum. The os clitoridis was 43% the length and 24% the height of the os penis. On the basis of these first detailed descriptions of strepsirrhine external genitalia (for either sex), we characterize those of the female ring-tailed lemur as moderately "masculinized." Our results highlight certain morphological similarities and differences between ring-tailed lemurs and the most male-like of female mammals, the spotted hyena (Crocuta crocuta), and call attention to a potential hormonal mechanism of "masculinization" in female lemur development.

Irkilata Summary Ovotesticular disorder of sex development (OTDSD) is a rare condition and defined as the presence of ovarian and testicular tissue in the same individual. Most of patients with OTDSD have female internal genital organs. In this report, we present a case in which, we demonstrated prostate tissue using endoscopic and radiologic methods in a 46-XX, sex determining region of the Y chromosome negative male phenotypic patient, with no female internal genitalia. Existence of prostate in an XX male without SRY is rarely seen and reveals a complete male phenotype. This finding is critical to figure out what happens in embryonal period. [source] | |||||||||||||
