Abstract

Sexual dysfunction is defined as "disturbances in sexual desire and in the psychophysiological changes that characterize the sexual response cycle and cause marked distress and interpersonal difficulty". The female sexual response cycle consists of three phases: desire, arousal, and orgasm. Various organs of the external and internal genitalia, e.g. vagina, clitoris, labia minora, vestibular bulbs, pelvic floor muscles and uterus, contribute to female sexual function. During sexual arousal, genital blood flow and sensation are increased. The vaginal canal is moistened (lubrication). During orgasm, there is rhythmical contraction of the uterus and pelvic floor muscles. Within the central nervous system, hypothalamic, limbic-hippocampal structures play a central role for sexual arousal. Sexual arousal largely depends on the sympathetic nervous system. Moreover, nonadrenergic/noncholinergic neurotransmitters (NANC), e.g. vasoactive intestinal polypeptide (VIP) and nitric oxide (NO), are involved in smooth muscle relaxation and enhancement of genital blood flow. Furthermore, various hormones may influence female sexual function. Estrogen has a significant role in maintaining vaginal mucosal epithelium as well as sensory thresholds and genital blood flow. Androgens primarily affect sexual desire, arousal, orgasm and the overall sense of well-being. The internationally accepted classification of female sexual dysfunction consists of hypoactive sexual desire disorders, sexual aversion disorders, sexual arousal disorders, orgasmic disorders and sexual pain disorders. Vascular insufficiency, e.g. due to atherosclerosis, and neurologic diseases, e.g. diabetic neuropathy, are major causes of sexual dysfunction. Additionally, sexual dysfunction may be due to changes in hormonal levels, medications with sexual side effects or of psychological origin. For the diagnosis of female sexual dysfunction, a detailed history should be taken initially, followed by a physical examination and laboratory studies. Physiologic monitoring of parameters of arousal potentially allows to diagnose organic diseases. Recordings at baseline and following sexual stimulation are recommended to determine pathologic changes that occur with arousal. Duplex Doppler sonography, photoplethysmography or the measurement of vaginal and minor labial oxygen tension may help to evaluate genital blood flow. Moreover, measurements of vaginal pH and compliance should be performed. Neurophysiological examination, e.g. measurement of the bulbocavernosus reflex and pudendal evoked potentials, genital sympathetic skin response (SSR), warm, cold and vibratory perception thresholds as well as testing of the pressure and touch sensitivity of the external genitalia, should be performed to evaluate neurogenic etiologies. Medical management of female sexual dysfunction so far is primarily based on hormone replacement therapy. Application of estrogen results in decreased pain and burning during intercourse. The efficacy of various other medications, e.g. sildenafil, L-arginine, yohimbine, phentolamine, apomorphine and prostaglandin E1, in the treatment of female sexual dysfunction is still under investigation.
