Antidepressant nonadherence and sexual dysfunction among young adult males: the cross-sectional YAMAN study.

PURPOSE: Selective serotonin reuptake inhibitors are associated with high rates of nonadherence and sexual dysfunction, yet the correlation between these findings in young adult men is poorly characterized. We aimed to evaluate if young adult men are less willing to adhere to antidepressant treatment due to intolerable side effects, such as sexual dysfunction. METHODS: Deidentified, compensated survey that assessed baseline demographics, PHQ-8 and GAD-7 scores, attitudes towards antidepressant medication side effects, and perceptions of antidepressant medications including selective serotonin reuptake inhibitors, bupropion, and mirtazapine. RESULTS: From 665 delivered surveys, 505 respondents completed their survey (response rate: 76%), of which 486 were included for final analysis. After seeing common side effect profiles, our sample's willingness to take sexual function-sparing agents, such as bupropion or mirtazapine, was significantly greater than selective serotonin reuptake inhibitors (p < 0.001), with no significant difference between bupropion and mirtazapine (p = 0.263). The negative influence of erectile dysfunction and anorgasmia scored significantly higher than other common antidepressant side effects like weight gain, nausea, and dry mouth (range: p < 0.001, p = 0.043). With the exception of insomnia, participants indicated that experiencing sexual dysfunction while taking an antidepressant medication would lead to nonadherence at a significantly higher frequency than any other side effect assessed (range: p < 0.001, p = 0.005). CONCLUSION: The risk of experiencing sexual side effects when taking antidepressants could lead young adult men to become nonadherent to these medications. Strategies to augment the effectiveness of antidepressants, such as shared decision-making and the use of sexual function-sparing agents, are critical.

Characteristics of systemic testosterone therapy for female hypoactive sexual desire disorder-a claims database analysis.

BACKGROUND: Testosterone therapy (TTh) is recommended for postmenopausal women with hypoactive sexual desire disorder (HSDD); however, there remain insufficient data to support use of TTh in premenopausal women with sexual dysfunction. AIM: In this study, we used a large national database to evaluate prescribing trends of TTh for women with HSDD. METHODS: We conducted a cohort analysis of information from electronic health records acquired from the data network TriNetX Diamond. The study cohort consisted of women 18-70 years of age with a diagnosis of HSDD. We analyzed trends of testosterone prescriptions, routes of testosterone administration, and coadministration of testosterone with estrogen. OUTCOMES: Despite an increase in rates of testosterone prescriptions for HSDD, there remains a high degree of variability in the duration of treatment, route of administration, and coadministration of estrogen with significant underprescription of testosterone. RESULTS: Our query of the TriNetX database led to the identification of 33 418 women diagnosed with HSDD at a mean age of 44.2 ± 10.8 years, among whom 850 (2.54%) women received a testosterone prescription. The testosterone prescriptions were highly variable with regard to duration and route of administration and coadministration with estrogen. For all patients until 2015, the prevalence of testosterone prescriptions for HSDD showed a positive quadratic relation was observed. Since 2015 a linear increase in prevalence was observed, with the highest rate of increase for patients aged 41-55 years. CLINICAL IMPLICATIONS: The findings of this study reveal a significant need for further research investigating the optimal use of TTh to enhance the sexual health of women with HSDD, and further studies on the long-term effects of testosterone use must be undertaken to ensure that patients have access to safe and effective treatment. STRENGTHS AND LIMITATIONS: Limitations to this study include patient de-identification and lack of availability of testosterone dosage data. However, this study also has many strengths, including being the first, to our knowledge, to characterize the prescribing trends of testosterone for women with HSDD. CONCLUSION: Testosterone therapy should be considered as a potential therapy for premenopausal female patients with HSDD. Further studies on the long-term effects of testosterone use must be undertaken to address disparities in the management of HSDD and to ensure patients can access treatment.

Post-Finasteride Syndrome And Post-Ssri Sexual Dysfunction: Two Clinical Conditions Apparently Distant, But Very Close.

Post-finasteride syndrome and post-SSRI sexual dysfunction, are two poorly explored clinical conditions in which men treated for androgenetic alopecia with finasteride or for depression with SSRI antidepressants show persistent side effects despite drug suspension (e.g., sexual dysfunction, psychological complaints, sleep disorders). Because of some similarities in the symptoms, common pathological mechanisms are proposed here. Indeed, as discussed, clinical studies and preclinical data obtained so far suggest an important role for brain modulators (i.e., neuroactive steroids), neurotransmitters (i.e., serotonin, and cathecolamines), and gut microbiota in the context of the gut-brain axis. In particular, the observed interconnections of these signals in these two clinical conditions may suggest similar etiopathogenetic mechanisms, such as the involvement of the enzyme converting norepinephrine into epinephrine (i.e., phenylethanolamine N-methyltransferase). However, despite the current efforts, more work is still needed to advance the understanding of these clinical conditions in terms of diagnostic markers and therapeutic strategies.

[Sexual dysfunction on the background of antidepressant therapy]. / Seksual'nye disfunktsii na fone antidepressivnoi terapii.

The review is devoted to the problem of sexual dysfunction caused by taking antidepressants. Sexual dysfunction is widespread, but it is not reported, and its impact on the quality of life and compliance of patients is underestimated. Partly because of its bidirectional association with depression, sexual dysfunction is difficult to diagnose. Possible mechanisms and risk factors associated with sexual dysfunction in patients with depression are considered. The data on the frequency of sexual dysfunction with the use of various antidepressants are given. Therapeutic strategies for sexual dysfunction associated with taking antidepressants are described. The advantages of agomelatin as an antidepressant associated with a low risk of sexual side effects are emphasized.

Managing antipsychotic-related sexual dysfunction in patients with schizophrenia.

INTRODUCTION: Schizophrenia is a psychotic disorder and one of the most severe and impactful mental illnesses. Sexual dysfunction is highly prevalent in patients with schizophrenia but remains underdiagnosed and undertreated. Sexual dysfunction is frequently attributed to antipsychotics which may reduce medication adherence, but negative symptoms can also reduce sexual drive. AREAS COVERED: This review provides an overview of the current knowledge about sexual dysfunction in patients with schizophrenia. The authors first review the literature concerning the mechanisms of sexual dysfunction and explore the impact of antipsychotics on sexual function. Finally, they present the available non-pharmacological and pharmacological treatment strategies for sexual dysfunction in patients with schizophrenia. EXPERT OPINION: Sexual dysfunction in patients with schizophrenia is still underrated by clinicians despite having a negative impact on the quality of life and therapeutic adherence. Antipsychotic treatment is still perceived as a major cause of sexual impairment. Psychiatrists must be aware of this condition and actively question the patients. A comprehensive approach, addressing pharmacological and non-pharmacological aspects, is fundamental for managing sexual dysfunction in schizophrenia. Pharmacological strategies include (1) Serum-level adjustment of the antipsychotic dose, if possible (2) switching to a well-tolerable antipsychotic (aripiprazole, brexpiprazole) and (3) adding a coadjuvant drug (phosphodiesterase-5 inhibitors).

Does MDMA have treatment potential in sexual dysfunction? A systematic review of outcomes across the female and male sexual response cycles.

INTRODUCTION: Sexual health, an integral component of overall well-being, is frequently compromised by common yet underdiagnosed sexual dysfunctions. Traditional interventions encompass pharmaceutical and psychological treatments. Unconventional therapies, like MDMA, offer hope for sexual dysfunction. This review delves into MDMA's effects on sexual responsiveness and its potential role in treating sexual dysfunction. OBJECTIVES: The purpose of this review is to elucidate effects of MDMA on different domains of the female and male sexual response cycles. METHODS: We conducted a systematic review on the effects of MDMA on each domain of the female and male sexual response cycles. PubMed, MEDLINE, and EMBASE were queried, and results were screened using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Search terms utilized were "MDMA" or "ecstasy" in combination with "desire," "arousal," "lubrication," "orgasm," "pleasure," "libido," "erection," and "ejaculation." Inclusion criteria for this review were MDMA use by study subjects and sexual outcomes in at least 1 domain of the female and/or male sexual response cycles were described and measured. Randomized controlled trials, cohort studies (both prospective and retrospective), surveys, and literature reviews published between January 2000 and June 2022 were included. Case reports and studies that did not address conditions of interest were excluded from analysis. Duplicated search results were screened out. The remaining studies were then read in full text to ensure they met inclusion and exclusion criteria for analysis. RESULTS: We identified 181 studies, of which 6 met criteria for assessment of the female sexual response cycle and 8 met criteria for assessment of the male sexual response cycle. Four of 6 studies reported increased sexual desire with MDMA use among women. Arousal and lubrication were improved with MDMA use in 3 of 4 studies, but they were not affected in 1 randomized control study. In men, 7 studies evaluated the effects of MDMA on desire and/or arousal, 5 studies measured impact on erection, 3 on orgasm, and 2 on ejaculation. Sixty percent of interview-based studies reported increased sexual desire in men, while 40% reported mixed or no effect. Two studies reported impairment of erection, 2 reported mixed effects, and 1 reported fear of erection impairment. In both men and women, all studies evaluating orgasm reported delay in achieving orgasm but increased intensity and pleasure if achieved. Primary outcome measures were variable and largely qualitative. CONCLUSION: Our findings suggest that MDMA generally increases sexual desire and intensifies orgasm when achieved. While producing conflicting evidence on sexual arousal in both sexes, MDMA may impair erectile and ejaculatory function in men.

Repercusión de vortioxetina sobre la función sexual frente a otros antidepresivos / Impact of vortioxetine on sexual function compared to other antidepressants

Objetivo Analizar la repercusión del antidepresivo vortioxetina sobre la función sexual, frente a inhibidores selectivos de la recaptación de serotonina (ISRS) e inhibidores selectivos mixtos de la recaptación de serotonina y noradrenalina (IRSN o Duales) en pacientes con depresión. Material y métodos Estudio analítico, observacional, longitudinal y prospectivo en el que se incluyeron hombres y mujeres mayores de 18años con trastorno depresivo y actividad sexual en pareja, separándolos en dos grupos: 1)de estudio: inician tratamiento con vortioxetina; 2)control: mantienen tratamiento con ISRS o Duales. Se realizaron tres visitas: inclusión, seguimiento a las 4semanas y final 3meses desde la inclusión. El periodo total de seguimiento fue de 3meses. Resultados Se incluyeron 87 pacientes (edad media, 46,85años). Al final del estudio se hallaron diferencias significativas (DS) en el valor medio de la suma de las puntuaciones de los dominios evaluadores de la respuesta sexual del cuestionario de Función Sexual de la Mujer (FSM-2) entre el grupo de estudio y el de control (22,42±4,39 y 16,13±7,76, respectivamente), con menor riesgo de disfunción sexual en las mujeres tratadas con vortioxetina. También menor riesgo de disfunción sexual en estas mismas mujeres en los dominios de deseo, lubricación, orgasmo, frecuencia sexual y satisfacción sexual. Estas diferencias no se hallaron al evaluar la función sexual masculina. Conclusiones Las mujeres tratadas con vortioxetina presentaron mejor función sexual que las tratadas con ISRS o Duales y menor riesgo de disfunción sexual (AU)

Objective To analyze the impact of the antidepressant vortioxetine on sexual function, compared to selective serotonin reuptake inhibitors (SSRIs) and mixed selective serotonin and norepinephrine reuptake inhibitors (IRSN or Dual) in patients with depression. Material and methods Analytical, observational, longitudinal and prospective study, which included men and women over 18years of age, with depressive disorder and sexual activity with a partner, separating them into two groups: (i)study, starting treatment with vortioxetine; (2)control, maintaining treatment with SSRIs or Duals. Three visits were made: inclusion, follow-up at 4weeks and final 3months from inclusion. The total follow-up period was 3months. Results A total of 87 patients were included (mean age 46.85years). At the end of the study, significant differences (SD) were found in the mean value of the sum of the scores of the evaluative domains of the sexual response of the Women's Sexual Function Questionnaire (FSM-2) between the study group and the control (22.42±4.39 and 16.13±7.76, respectively), with a lower risk of sexual dysfunction in women treated with vortioxetine. Also, lower risk of sexual dysfunction in these same women in the domains of desire, lubrication, orgasm, sexual frequency and sexual satisfaction. These differences were not found when assessing male sexual function. Conclusions Women treated with vortioxetine presented better sexual function than those treated with SSRIs or Duals and a lower risk of sexual dysfunction (AU)

Effects of Aphrodite (an Herbal Compound) on SSRI-Induced Sexual Dysfunctions and Depression in Females with Major Depressive Disorder: Findings from a Randomized Clinical Trial.

Background and Objectives: Almost by default, people with major depression disorder (MDD) also report sexual health issues. This holds even more true when sexual dysfunctions are SSRI-induced. Herbal compounds may have the power to counterbalance such sexual dysfunctions, though research is still scarce. Therefore, we assessed females with diagnosed MDD treated with a standard SSRI (sertraline) and reporting SSRI-induced sexual dysfunctions, and we asked whether compared to placebo, Aphrodite (a blend of ginger, saffron, cinnamon, thistle, and Tribulus terrestris) may favorably impact on sexual dysfunctions, and on symptoms of depression, anxiety, and sleep disturbances. Materials and Methods: A total of 41 females (mean age: 35.05 years) with diagnosed MDD, treated with sertraline (a standard SSRI) at therapeutic dosages, and reporting SSRI-induced sexual dysfunction, were randomly assigned either to Aphrodite or to the placebo condition. At baseline and four and eight weeks later (study end), participants completed a series of self-rating questionnaires covering symptoms of sexual dysfunction, depression, anxiety, and sleep complaints. Results: Symptoms of sexual dysfunction, depression, and anxiety decreased over time, but more so in the Aphrodite condition, compared to the placebo condition (significant p-values and large effect sizes). Over time, sleep disturbances decreased irrespective of the study condition. Conclusions: The pattern of results suggests that compared to placebo, Aphrodite appeared to improve symptoms of sexual dysfunction, depression, and anxiety among females with diagnosed MDD and SSRI-induced sexual dysfunction. Further and similar studies should investigate the underlying psychophysiological mechanisms.

Sexual Dysfunction in Schizophrenia: A Systematic Review and Meta-Analysis.

Importance: In individuals with schizophrenia, antipsychotic-induced dysfunctions are frequent but often underexplored in clinical practice. Objective: To synthetize the data of observational studies exploring the prevalence of sexual dysfunction in individuals with schizophrenia-spectrum disorders as well as associated factors. Data Sources: A systematic literature search without language or time restrictions was conducted in Google, Google Scholar, PubMed/MEDLINE, Science Direct, and Université Sorbonne Paris Cité for studies published up to June 8, 2022. Study Selection: All observational studies reporting a prevalence of sexual dysfunction in schizophrenia-spectrum disorder were included. Data Extraction and Synthesis: The MOOSE guidelines with independent extraction by 2 observers and random-effects models were used. Main Outcomes and Measures: The prevalence of sexual dysfunction and each specific dysfunction. Results: A total of 72 of 1119 studies from 33 countries on 6 continents published from inception to June 2022 were included with a total of 21 076 participants with schizophrenia. The pooled global prevalence of sexual dysfunctions was 56.4% (95% CI, 50.5-62.2), with a prevalence of 55.7% (95% CI, 48.1-63.1) for men and 60.0% (95% CI, 48.0-70.8) for women. The most frequent sexual dysfunction was erectile dysfunction in men (44%; 95% CI, 33.5-55.2), followed by loss of libido in men (41%; 95% CI, 30.7-51.4), ejaculation dysfunction in men (39%; 95% CI, 26.8-51.8), orgasm dysfunction in women (28%; 95% CI, 18.4-40.2), and amenorrhea in women (25%; 95% CI, 17.3-35.0). Factors associated with heterogeneity were study design, time and location, sociodemographic data, alcohol use disorder, psychiatric diagnosis, illness severity, and the use of antidepressants and anxiolytics. Sexual dysfunctions were more frequent in schizophrenia vs schizoaffective disorders, and erectile disorders were less frequent in individuals with longer illness duration. Antidepressant and mood stabilizer prescriptions were associated with lower rates of erection disorders (ß, -6.30; 95% CI, -10.82 to -1.78); P = .006 and -13.21; 95% CI, -17.59 to -8.83; P < .001, respectively) and ejaculation disorders (ß, -6.10; 95% CI, -10.68 to -1.53; P = .009 and ß, -11.57; 95% CI, -16.34 to -6.80; P < .001, respectively). No obvious improvements in the rates of sexual dysfunction at other times were found, and there were conflicting results regarding antipsychotic classes. Conclusions and Relevance: This systematic review and meta-analysis found a high prevalence of sexual dysfunction among individuals with schizophrenia, with considerable heterogeneity in associated factors. The findings also suggest that some dysfunctions may be explained by schizophrenia. The association between lower rates of dysfunction and antidepressant use suggests that treating comorbid depression could be an effective strategy to improve sexual health. A lack of data on metabolic parameters and physical health in general was also noted, while these issues are frequent in the care of schizophrenia.

Initial observations on sexual dysfunction as a symptom of chemotherapy-induced peripheral neuropathy.

Introduction: Peripheral neuropathy (PNP) in feet and/or hands and sexual dysfunction are common side effects of cancer therapies. In patients with other diseases, there is evidence of an association between peripheral nervous system disorders and sexual dysfunction due to the impact of impaired neuronal control on genital organ sensitivity. In cancer patient interviews, it has now been observed that PNP and sexual dysfunction may be related. The aim of the study was to investigate the potential association between PNP, sexual dysfunction, and physical activity behavior. Methods: Ninety-three patients with PNP of the feet and/or hands were interviewed in August/September 2020 in a cross-sectional study regarding medical history, sexual dysfunction and functionality of the genital organs. Results: Thirty-one persons who participated in the survey provided seventeen evaluable questionnaires (four men, thirteen women). Nine women (69%) and three men (75%) reported sensory disorders of the genital organs. Three men (75%) had erectile dysfunction. All men who had sensory symptoms of the genital organs received chemotherapy, and one man also received immunotherapy. Eight women were sexually active. Five (63%) of them reported genital organ symptoms and mainly lubrication disorders. Four (80%) of the five sexually inactive women reported genital organ symptoms. Eight of the nine women with sensory symptoms of the genital organs received chemotherapy, and one woman received immunotherapy. Discussion: Our limited data suggest genital organ sensory symptoms in chemotherapy and immunotherapy patients. Genital organ symptoms do not appear to be directly related to sexual dysfunction, and the association between PNP and genital organ symptoms appears to be more pronounced in sexually inactive women. Chemotherapy could cause sensory symptoms of the genital organs and sexual dysfunction by damaging genital organ nerve fibers. Chemotherapy and anti-hormone therapy (AHT) could trigger a disturbance of the hormone balance, which in turn could be causative for sexual dysfunction. It remains open whether the cause of these disorders is the symptomatology of the genital organs or the altered hormone balance. The significance of the results is limited due to the small number of cases. To our knowledge, this study is the first of its kind in cancer patients and allows a better understanding of the association between PNP, sensory symptoms of the genital organs, and sexual dysfunction. Conclusion: In order to be able to narrow down the cause of these initial observations in cancer patients more precisely, larger studies are needed that can relate the influence of cancer therapy-induced PNP, physical activity level and hormone balance to sensory symptoms of the genital organs and sexual dysfunction. The methodology of further studies should take into account the frequent problem of low response rates in surveys on sexuality.

A clinical review of antidepressants, their sexual side-effects, post-SSRI sexual dysfunction, and serotonin syndrome.

Depression and anxiety are common, with one in six people experiencing symptoms in any given week. Of these people, 8.32 million are prescribed antidepressants. People living with HIV are likely to experience psychiatric disorder, with one in three experiencing depression and anxiety, and being at greater risk of developing post-traumatic stress disorder. Sexual side-effects of psychotropic medication are very common, cause distress, and can persist even after the medication has been withdrawn. Antidepressants are powerful drugs and can have severe interactions with many other substances. This article seeks to raise awareness of sexual side-effects of psychotropic medications and draw attention to ethical issues related to post selective serotonin reuptake inhibitor sexual dysfunction (PSSD). Additional risk factors and interactions between psychotropic medications and recreational drugs are identified. Recommendations are made to improve care and clinical outcomes through the development of therapeutic alliances.

[Impact of vortioxetine on sexual function compared to other antidepressants]. / Repercusión de vortioxetina sobre la función sexual frente a otros antidepresivos.

OBJECTIVE: To analyze the impact of the antidepressant vortioxetine on sexual function, compared to selective serotonin reuptake inhibitors (SSRIs) and mixed selective serotonin and norepinephrine reuptake inhibitors (IRSN or Dual) in patients with depression. MATERIAL AND METHODS: Analytical, observational, longitudinal and prospective study, which included men and women over 18years of age, with depressive disorder and sexual activity with a partner, separating them into two groups: (i)study, starting treatment with vortioxetine; (2)control, maintaining treatment with SSRIs or Duals. Three visits were made: inclusion, follow-up at 4weeks and final 3months from inclusion. The total follow-up period was 3months. RESULTS: A total of 87 patients were included (mean age 46.85years). At the end of the study, significant differences (SD) were found in the mean value of the sum of the scores of the evaluative domains of the sexual response of the Women's Sexual Function Questionnaire (FSM-2) between the study group and the control (22.42±4.39 and 16.13±7.76, respectively), with a lower risk of sexual dysfunction in women treated with vortioxetine. Also, lower risk of sexual dysfunction in these same women in the domains of desire, lubrication, orgasm, sexual frequency and sexual satisfaction. These differences were not found when assessing male sexual function. CONCLUSIONS: Women treated with vortioxetine presented better sexual function than those treated with SSRIs or Duals and a lower risk of sexual dysfunction.

Selective serotonin reuptake inhibitors, post-treatment sexual dysfunction and persistent genital arousal disorder: A systematic review.

PURPOSE: Adverse effects of selective serotonin reuptake inhibitors (SSRIs) on sexual function have been an important area of research for many years. However, the duration of SSRI-associated sexual adverse effects, and their possible persistence after treatment discontinuation, is still uncertain. The aims of the current systematic review were first to identify existing evidence of sexual dysfunction following SSRI discontinuation, and to provide an account of reported symptoms and proposed treatment options; and second, to establish whether current literature allows accurate estimates of the prevalence of such sexual dysfunction. METHODS: A systematic review was conducted on PubMed, Embase, and Google Scholar; papers with clinical data regarding patients with persistent sexual dysfunction after SSRI treatment suspension were included. RESULTS: Overall, two retrospective interventional studies, six observational studies and 11 case reports were judged eligible for inclusion. It was not possible to determine reliable estimates of prevalence. Similarly, a cause-effect relationship between SSRI exposure and persistent sexual impairment could not be ascertained. Nonetheless, the potential for continued sexual disturbances despite discontinuation could not be entirely ruled out. CONCLUSIONS: There is a need to investigate a possible dose-response relationship between SSRI exposure and persistent sexual adverse effects. Treatment options for persistent dysfunctions remain limited, but novel therapeutic approaches may be required in order to address an otherwise neglected need for sexual well-being.

The pathophysiology of Post SSRI Sexual Dysfunction - Lessons from a case study.

BACKGROUND: Although Post-SSRI Sexual Dysfunction (PSSD) has finally been recognized by the European Medicines Agency as a medical condition that can outlast discontinuation of SSRI and SNRI antidepressants, this condition is still largely unknown by patients, doctors, and researchers, and hence, poorly understood, underdiagnosed, and undertreated. OBJECTIVE: Becoming familiar with the symptomatology of PSSD and understanding the underlying mechanisms and treatment options. METHOD: We applied a design thinking approach to innovation to 1) provide insights into the medical condition as well as the personal needs and pains of a targeted patient; and 2) generate ideas for new solutions from the perspective of this particular patient. These insights and ideas informed a literature search on the potential pathophysiological mechanisms that could underlie the patient's symptoms. RESULTS: The 55-year-old male patient developed symptoms of low libido, delayed ejaculation, erectile dysfunction, 'brain zaps', overactive bladder and urinary inconsistency after discontinuation of the SNRI venlafaxine. In many of these symptoms a dysregulation in serotonergic activity has been implicated, with an important role of 5-HT1A receptor downregulation and possible downstream effects on neurosteroid and oxytocin systems. CONCLUSIONS: The clinical presentation and development of symptoms are suggestive of PSSD but need further clinical elaboration. Further knowledge of post-treatment changes in serotonergic - and possibly noradrenergic - mechanisms is required to improve our understanding of the clinical complaints and to inform appropriate treatment regimes.

Sexual function improves as depressive symptoms decrease during treatment with escitalopram: results of a naturalistic study of patients with major depressive disorder.

BACKGROUND: Major depressive disorder (MDD) is closely associated with sexual dysfunction, which may worsen during treatment with selective serotonin reuptake inhibitors (SSRIs) due to the side effects of pharmacologic treatment. AIM: To examine the association between sexual function and severity of MDD in drug-naïve patients as compared with healthy controls and how treatment with SSRIs affects sexual function over time in individuals with MDD. Interaction with gender and treatment response was examined. METHODS: In 92 patients with MDD, we measured MDD severity with 6- and 17-item versions of the Hamilton Depression Rating Scale (HDRS6 and HDRS17) and the level of sexual function with the Changes in Sexual Functioning Questionnaire at baseline and 4, 8, and 12 weeks after initiating treatment with escitalopram. Baseline sexual function was compared with the sexual function of 73 healthy controls. Linear regression models were used to assess differences in sexual function between healthy controls and patients and change in sexual function from baseline to week 12. Linear mixed models were used to assess differences in change in sexual function between treatment response groups. OUTCOMES: Outcomes included total scores on the HDRS6, HDRS17, and Changes in Sexual Functioning Questionnaire and changes in total scores from baseline to week 12. RESULTS: Unmedicated patients with MDD reported impaired sexual function as compared with healthy controls. Level of sexual function was not associated with severity of MDD at baseline. Patients' sexual function improved significantly during treatment, which was coupled with amelioration of depressive symptoms. Treatment response groups (remitters, intermediate responders, nonresponders) did not predict change in sexual function. Gender had no effect on sexual dysfunction symptoms during treatment. CLINICAL IMPLICATIONS: Major depression is a risk factor for sexual problems, and improvement in sexual function was coupled with amelioration of depressive symptoms. STRENGTHS AND LIMITATIONS: Among its strengths, this was a naturalistic study reflecting real-world settings in clinical practice. It additionally included a baseline measurement of sexual function and MDD severity on drug-naïve patients prior to the initiation of treatment. Finally, the follow-up of 12 weeks extends beyond the acute phase of treatment in which previous research has observed a peak in sexual side effects. In terms of limitations, there was no placebo arm; thus, the study cannot attribute the effects on sexual function to treatment with antidepressants per se. Also, the patients were young, which may have served as a protective factor against sexual side effects. CONCLUSION: Sexual dysfunction was strongly associated with MDD and improved in parallel with overall symptoms of depression across a standard 12-week treatment with SSRI antidepressants. CLINICAL TRIAL REGISTRATION: NCT02869035 (https://clinicaltrials.gov/ct2/show/NCT02869035).

Association Between Sexual Dysfunction and Dose of Atypical Antipsychotics: Essential to Learn the Basics.

There is paucity of data on sexual dysfunction associated with atypical antipsychotics in Indian population. We estimated the prevalence of sexual dysfunction and assessed dose dependency, if any, in patients on monotherapy of atypical antipsychotics. This cross-sectional study analyzed the data from patients with F20 to F29 (International Classification of Diseases 10th Revision, ICD-10) receiving monotherapy of risperidone (group 1), olanzapine (group 2), or quetiapine (group 3) for at least 4 weeks. The sexual function of participants was assessed using Arizona sexual experiences (ASEX) scale. Chlorpromazine (CPZ) equivalent dose and doses in terms of dose years were calculated. Kruskal-Wallis test, Mann-Whitney U-test, and Pearson correlation were used for analysis. Of the 154 subjects, 65.58% were males, with 44%, 48%, and 8% receiving risperidone, olanzapine, and quetiapine, respectively. The mean duration of treatment was 20.9 weeks. Lower ASEX scores were reported with quetiapine. The differences in mean ASEX scores between groups 1 and 2 were statistically significant for sex drive (P = .016), sexual arousal (P = .025), and overall score (P = .037). Sexual dysfunction was more frequent with risperidone (48.5%) than with olanzapine (28.4%) and quetiapine (0%). In group 1, the duration of therapy positively correlated with the mean scores of sexual desire (P = .003) and arousal (P = .033), but this was not the case for group 2 (receiving olanzapine). The mean CPZ equivalent doses were comparable between the groups (P = .064); those receiving <200 mg CPZ dose equivalents showed greater sexual impairment. We conclude that the occurrence of atypical antipsychotic-induced sexual dysfunction is not dose dependent. Olanzapine has a better safety profile in terms of sexual dysfunction, whereas the data reflecting the experience with quetiapine are insufficient.
