Are reproductive life events in women associated with an increased risk of sexual dysfunction? Female sexual dysfunction effects up to 40% of women in the United States between 18 and 59 years of age. Sexual dysfunction may be accompanied by fluctuations in gonadal hormone secretion, making women more vulnerable to sexual symptoms, especially during times of reproductive life events. Reproductive life events, such as the use of birth control pills, various phases of the menstrual cycles, postpartum and lactation states, and perimenopause, are highly correlated with changes in sex steroids. As an understanding of the role of sex steroids on sexual functioning is elucidated, clinicians will be able to offer more specific and effective treatment options for women during various phases of reproductive life. Several case studies are presented to illustrate the unique clinical considerations that a clinician must consider when treating the biologic component of female sexual dysfunction.

Sexual dysfunction related to antidepressants, particularly serotonin reuptake inhibitors is a major cause of premature treatment discontinuation. This places patients at increased risk for recurrence, relapse, chronicity, and mortality (eg, suicide). The clinical assessment requires a comprehensive evaluation of sexual function, including libido, arousal, orgasm, and resolution prior to affective disorder, disturbances associated with the emergence of depression, and changes or dysfunctions associated with antidepressant treatment. Other factors to be included for evaluating sexual dysfunction include inquiry for concurrent medical conditions, somatic treatments, lifestyle risk factors, and response to antidepressants. Current treatment approaches to antidepressant-associated sexual dysfunction have relied on open-label reports, literature reviews, and clinical wisdom. Without double-blind, placebo-controlled studies to support them, too much non-evidence-based treatment may be offered to patients. Advances into nonadrenergic-noncholinergic novel signal transduction, specifically phosphodiesterase type-5 inhibitors, offer new opportunities for developing evidence-based treatments for this side effect and improving depression disease management outcomes.

What drives the human sexual response cycle? The human sexual response cycle is a highly complex phenomenon that encompasses many transmitters and transmitter systems centrally and peripherally. The endocrine system is also intricately involved in the brain and in the periphery organs. Integration of these systems is a function of the nervous system that ultimately produces a vast array of cognitive, emotional, physiological, and behavioral responses. Therefore, it is not surprising that a disturbance in even a single system will lead to dysfunction in one or more phases of the sexual response cycle. This article highlights the complex roles the aminergic system plays along with key hormones that are equally involved. The article also points out how rudimentary and fragmented our knowledge is in this field and how few controlled studies are available. The potential for development of specific agents that target selective sexual dysfunctions is exemplified in sildenafil, the first such agent ever to be brought to market.

Whose job is it to discover and manage patients' sexual concerns? If you believe that you have a role to play, just what is that role and how will you perform it? Sexual disorders are common, yet infrequently diagnosed. A willingness to inquire about sexual function is the most critical diagnostic step for clinicians. Once a problem is discovered, a systematic diagnostic process can uncover etiologic organic and psychogenic factors using customary diagnostic tools, including taking a psychosexual and medical history, comprehensive and focused physical examinations, psychological assessment instruments, laboratory tests, and special procedures.

What is the current knowledge concerning the pharmacologic treatment of human sexual dysfunction? A number of interventions, including oral phophodiesterase inhibitors and intracorporeal agents with vasodilatory effects, are available to treat male erectile disorder. Serotonergic drugs have been shown to be effective in the treatment of rapid ejaculation. Various lines of research suggest that high dosages of androgenic agents may eventually have a role in the treatment of decreased libido in females. There may be a role for phophodiesterase inhibitors in the treatment of a subgroup of women with arousal disorders. Normal sexual function involves successful integration of biological, psychological, and interpersonal influences. Clinical psychiatry with its biopsychosocial model should incorporate the treatment of human sexual dysfunction within its purview.
