Sexual problems in both sexes appear to be widespread in society, influenced by both health-related and psychosocial factors, and are associated with impaired quality of life. Epidemiological studies suggest that modifiable health behaviors, including physical activity and leanness, are associated with a reduced risk for erectile dysfunction (ED) among men. Data from other surveys also indicate a higher prevalence of impotence in obese men. Obesity may be a risk factor for sexual dysfunction in both sexes; the data for the metabolic syndrome are very preliminary and need to be confirmed in larger epidemiologic studies. The high prevalence of ED in patients with cardiovascular risk factors suggests that abnormalities of the vasodilator system of penile arteries play an important role in the pathophysiology of ED. We have shown that one-third of obese men with ED can regain their sexual activity after 2 y of adopting health behaviors, mainly regular exercise and reducing weight. Western societies actually spend a huge part of their health care costs on chronic disease treatment and interventions for risk factors. The adoption of healthy lifestyles can reduce the prevalence of obesity and the metabolic syndrome, and hopefully the burden of sexual dysfunction.

This article boldly challenges the dynamic psychiatrist to engage directly and vigorously into a matter that many would prefer to regard somewhat passively. That passivity is no longer acceptable. The metabolic syndrome has become a central medical concern because of the epidemic of obesity. It causes cardiovascular disease, diabetes, some cancers, sleep apnea, sexual dysfunction, and infertility. Obesity leads to depression, anxiety, and osteoarthritis. Some atypical antipsychotic medicines contribute to the metabolic syndrome, but the epidemic is widespread independent of atypicals. Practical steps by psychiatrists to monitor metabolic parameters are not as simple as they appear to be. Yet this is an area of clinical practice that cannot be ignored. Psychodynamic therapists need to awaken to the health of patients because the metabolic syndrome is more life-threatening than self-mutilation and many other self-destructive behaviors. The article discusses countertransference and transference issues stirred up when physicians begin to take responsibility for the total health of their patients. Freud oriented us to focus on both sides of the mind body relationship. Recent research on obesity, hypertension, diabetes, sleep, anxiety,depression, exercise and dyslipidemia is reviewed from the viewpoint of how it impinges on the office practice of a dynamic psychiatrist.

There is ample evidence from many epidemiological studies that lower urinary tract symptoms (LUTS) and sexual dysfunction are strongly linked, independently of age and comorbidities such as hypertension, diabetes, dyslipidaemia and coronary heart disease. However, a causal link between both conditions is not yet established. Four pathophysiological mechanisms currently support the relationship between LUTS and erectile dysfunction (ED): (i) The nitric oxide synthase (NOS)/NO theory; there is a reduction in NOS-containing nerves in the prostate and bladder/urethra in patients with bladder outlet obstruction (BOO), and that lack of NO or loss of protein kinase G causes ED; (ii) The autonomic hyperactivity and metabolic syndrome hypothesis: benign prostatic hyperplasia (BPH) may be part of the metabolic syndrome, which includes cardiovascular diseases (e.g. hypertension, ischaemic heart disease) and diabetes mellitus, known risk factors for ED. Hypertension, obesity, and hyperinsulinaemia have all been claimed to be associated with an increased sympathetic activity. Increased sympathetic activity is involved in LUTS/BPH and may have a role in ED/sexual dysfunction, with noradrenaline and alpha1-adrenoceptors representing a common link; (iii) the Rho-kinase activation/endothelin pathway; there can be increased Rho-kinase activity, and consequently calcium sensitivity of the contractile machinery, in prostate smooth muscle in BPH, the detrusor in BOO, corpora cavernosa in ED, and in the resistance vessels in hypertension. The actions of several factors beside noradrenaline (e.g. endothelin-1, angiotensin II), possibly involved in the increased smooth muscle activity found in both LUTS/BPH and sexual dysfunction, are dependent on Rho-kinase activity. Thus increased Rho-kinase activity might represent a common link between LUTS and sexual dysfunction; (iv) Pelvic atherosclerosis; animal models mimicking pelvic ischaemia and hypercholesterolaemia show similar smooth muscle alterations of the detrusor and corpora. Pelvic ischaemia may induce the biological modifications described above and may thus represent as well a common link between LUTS and sexual dysfunction. Studies treating one condition (e.g. ED) and measuring the impact on the other (e.g. LUTS) should further contribute to support this common link.

Female sexual dysfunction (FSD) is a multifactorial set of conditions associated with multiple anatomical, physiological, biological, medical and psychological factors that can have major impact on self-esteem, quality of life, mood and relationships. Studies indicate that FSD is commonly seen in women who report a low level of satisfaction with partner relationship and in women with male partners who have erectile dysfunction. This complexity of FSD is augmented by the presence of chronic disease. Negative sexual effects are widely reported in studies of women with chronic diseases (such as metabolic syndrome, diabetes mellitus, chronic kidney disease, cancer, spinal cord injury, lupus, rheumatic diseases, Parkinson's disease, fibromyalgia and chronic pain) as compared to a general healthy female population. Physical problems, emotional problems and partnership difficulties arising from disease-related stress contribute to less active and less enjoyable sex life. Chronic pain, fatigue, low self-esteem as well as use of medications might reduce sexual function. These effects of chronic diseases on female sexual function still remain largely unstudied. The study by Manor and Zohar published in this issue of Harefuah draws our attention to the sexual dysfunction of women with breast cancer and examines their needs for information regarding their sexual function. In the absence of definite treatment evidence, psychological counseling, improved vaginal lubrication, low dose of hormonal therapy can be used to relieve FSD. Physicians must consider integrating diagnosis of their female patients' sexual needs and dysfunction, especially women with chronic diseases. Patients' education and counseling may contribute to a better quality of life in spite of their chronic disease.

Metabolic syndrome, a growing issue in women's health, is a cluster of health findings that increase the risk of cardiovascular events. The prevalence of metabolic syndrome is higher in women and is linked to several conditions unique to women's health, including polycystic ovary syndrome, gestational diabetes, pregnancy-induced hypertension, and female sexual dysfunction. Risk factors, screening strategies, and therapeutic management of metabolic syndrome in women are discussed.

Six second-generation antipsychotics (SGAs), aripiprazole, clozapine, olanzapine, quetiapine, risperidone and ziprasidone, are currently US FDA approved. The aim of this review is to investigate whether sex differences exist for efficacy and adverse effects of these drugs.Sex-related differences have been shown in the pharmacokinetics of cytochrome P450 (CYP), with a higher activity in females for CYP3A4 and CYP2D6. However, even if there are pharmacokinetic differences between females and males, significantly higher plasma concentrations in women have been demonstrated only for olanzapine and clozapine. To date, sex differences in adverse effects have not been well studied, but some adverse effects such as weight gain, hyperprolactinaemia and cardiac effects are reported to be particularly problematic for women. Most of the studies reviewed indicate that clozapine and olanzapine are associated with greater bodyweight gain than the other atypical antipsychotics, and that serious adverse effects such as metabolic syndrome, which includes increased visceral adiposity, hyperglycaemia, hypertension and dyslipidaemia induced by SGAs, are more frequent in females. According to most studies, the risk for cardiac adverse effects induced by SGAs is the same in male and female patients. Although women are at a lower risk of sudden cardiac death, they have a higher risk of induced long QT syndrome from antiarrhythmic and, probably, antipsychotic drugs. The propensity of sexual dysfunctions is higher with conventional antipsychotics than with SGAs. Additionally, there is some evidence that female sexual dysfunction is associated with high prolactin levels; however, whether the degree of prolactin level elevation is different between female and male patients remains controversial. There is no evidence for sex differences for any of the SGAs to cause a higher rate of extrapyramidal symptoms, acute dystonia or any other movement disturbance. Knowledge of the risks and benefits associated with the use of SGAs during pregnancy and lactation is limited, although the direction of dose adjustments during pregnancy depends on the drug and the enzyme that is responsible for its metabolism. In general, data on sex differences were mostly obtained by posthoc analysis and, therefore, the conclusions that can be drawn are limited. For a better understanding of the basic mechanisms of sex differences, future studies with a primary focus on this topic are required. Data that are more specific will help determine the extent to which these differences will have implications for clinical management.

Prostate cancer is one of the most common cancers in men. Androgen-deprivation therapy (ADT) is often employed in the treatment of recurrent and metastatic prostate cancer. Although its use as an adjuvant therapy has resulted in improved survival in a subset of patients, ADT also results in a multitude of endocrine complications. These complications affect quality of life and sense of well-being in these men. Some of the endocrine complications of ADT such as osteoporosis, sexual dysfunction, hot flashes, gynecomastia, and adverse body composition are well-known. Recently, insulin resistance, hyperglycemia, and metabolic syndrome have emerged as metabolic complications of castration and may be responsible for increased cardiovascular mortality in this population. In this article, we provide a detailed review of the endocrine complications of ADT, touching upon management strategies where applicable.

Endocrine disease frequently interrupts sexual function, and sexual dysfunction may signal serious endocrine disease. Diabetic autonomic neuropathy and endothelial dysfunction impair erectile function, and phosphodiesterase inhibition produces only moderate benefit. The effect of diabetes on women's sexual function is complex: the most consistent finding is a correlation between sexual dysfunction and depression. Reductions in testosterone level in men are associated with low sexual desire and reduced nocturnal erections and ejaculate volume, all of which improve with testosterone supplementation. The age-dependent decline in testosterone production in men is not associated with precise sexual symptoms, and supplementation has not been shown to produce sexual benefit. In women, sexual dysfunction has not been associated with serum testosterone, but this may be confounded by limitations of assays at low concentrations and by the greater importance of intracellular production of testosterone in women than in men. Testosterone supplementation after menopause does improve some aspects of sexual function in women, but long-term outcome data are needed. More research on the sexual effects of abnormal adrenal and thyroid function, hyperprolactinaemia, and metabolic syndrome should also be prioritised. We have good data on local management of the genital consequences of oestrogen lack, but need to better understand the potential role of systemic oestrogen supplementation from menopause onwards in sexually symptomatic women.

Erectile dysfunction is an important cause of decreased quality of life in men. It is estimated that approximately 30 million men in the US and 100 million worldwide may have erectile dysfunction. Data from epidemiological studies indicate a higher prevalence of impotence in obese men. Obesity may be a risk factor for sexual dysfunction in both sexes; data for the metabolic syndrome are very preliminary and need to be confirmed in larger epidemiological studies. The high prevalence of erectile dysfunction in patients with cardiovascular risk factors suggests that abnormalities of the vasodilator system of penile arteries play an important role in the pathophysiology of erectile dysfunction. Nitric oxide released during non-adrenergic, non-cholinergic neurotransmission and from the endothelium is probably the principal neurotransmitter mediating penile erection. It has been shown that chloroquine administration was associated with an increase in nitric oxide synthesis. Chloroquine was also postulated to enhance insulin sensitivity, which suggests potential benefit in treating the metabolic syndrome-related erectile dysfunction.

In the present study, we tested the effect of a Mediterranean-style diet on sexual function in women with the metabolic syndrome. Women were identified in our database of subjects participating in controlled trials evaluating the effect of lifestyle changes and were included if they had a diagnosis of female sexual dysfunction (FSD) associated with a diagnosis of metabolic syndrome, a complete follow-up in the study trial and an intervention focused mainly on dietary changes. Fifty-nine women met the inclusion/exclusion criteria; 31 out of them were assigned to the Mediterranean-style diet and 28 to the control diet. After 2 years, women on the Mediterranean diet consumed more fruits, vegetables, nuts, whole grain and olive oil as compared with the women on the control diet. Female sexual function index (FSFI) improved in the intervention group, from a mean basal value of 19.7+/-3.1 to a mean post-treatment value of 26.1+/-4.1 (P=0.01), and remained stable in the control group. C-reactive protein (CRP) levels were significantly reduced in the intervention group (P<0.02). No single sexual domain (desire, arousal, lubrication, orgasm, satisfaction, pain) was significantly ameliorated by the dietary treatment, suggesting that the whole female sexuality may find benefit from lifestyle changes. A Mediterranean-style diet might be effective in ameliorating sexual function in women with metabolic syndrome.
