Methadone is largely recognized as an effective treatment for opiate-dependent patients; however, it causes reduced brain dopaminergic action resulting in significant sexual dysfunction. Bupropion is a dopamine reuptake inhibitor which can potentially improve erectile function among male patients on methadone (MMT). This is a phase II, randomized, double-blind, parallel-group, placebo-controlled trial, involving 80 MMT male patients (73.4%) with mean age of 42.83 years ±9.68. These MMT male patients were randomly assigned into two groups to receive bupropion and placebo, respectively. The primary efficacy outcome measure was the difference between the two groups in end-point mean improvement scores using the measurement of Clinical Global Impression Scale adapted for Sexual Function (CGI-SF) at baseline (week 0) and at weeks 2, 4, and 6. Malay version of the sexual desire inventory-2 (SDI-2-BM) and Malay version of International Index of Erectile Function 15 (Mal-IIEF-15) domain scores were evaluated as secondary parameters. Improvement of the end-point mean from baseline were seen across the scores of SDI-2-BM (mean difference = 11.77 ± 2.90, 95% confidence interval (CI) [3.89, 19.54], p < .001) and Mal-IIEF-15 (mean difference = 8.37 ± 2.71, 95% CI [15.75, 0.99], p = .02), and the total plasma testosterone level (mean difference = 4.03, 95% CI [0.90, 7.15], p = .01). A categorical improvement of "much/very much improved" (CGI-SF score = 2) was reported by 58.3% ( n = 21/36) of bupropion SR-assigned versus 27.7% ( n = 10/36) placebo-assigned patient. Bupropion was well tolerated with no serious adverse events reported other than insomnia (17.7%). Six weeks of bupropion SR treatment reported significant improvement in key aspects of sexual function among male opiate-dependent patients on methadone maintenance treatment with emergent sexual dysfunction.

Cadmium chloride (CdCl2 ) has been reported to cause reproductive toxicity in male rats, mainly through oxidative stress. This study examined its effect on sexual behaviour, as one of the mechanisms of reproductive dysfunction, as well as the possible ameliorative effect of quercetin (QE) on same. Thirty male Wistar rats (10 weeks old), weighing 270-300 g, were used for this study. They were either orally administered 2% DMSO, CdCl2 (5 mg/kg b.w.), QE (20 mg/kg b.w.) or CdCl2 +QE, once daily for 4 weeks, before sexual behavioural studies. The 5th group received CdCl2 for 4 weeks and allowed 4-week recovery period, before sexual behavioural test. Rats were sacrificed after sexual behavioural studies. The blood, testis and penis were collected for biochemical assays. Cadmium increased mount, intromission and ejaculatory latencies, but reduced their frequencies, compared to control. Serum nitric oxide increased, while penile cyclic guanosine monophosphate reduced in the CdCl2 -exposed rats, compared to control. CdCl2 increased testicular cholesterol, but reduced 3β-hydroxysteroid dehydrogenase (3β-HSD) and 17β-HSD activities, and testosterone concentration. QE better attenuated these negative changes compared to withdrawal of CdCl2 treatment. In conclusion, CdCl2 suppressed steroidogenesis, penile erection and sexual behaviour, with poor reversal following withdrawal, while QE attenuated these effects.

Daud S, Zahid AZM, Mohamad M, Abdullah B, Mohamad NAN

Arch Gynecol Obstet, 2019 11;300(5):1279-1285.
PMID: 31435778 DOI: 10.1007/s00404-019-05273-y

PURPOSE: This study aims to determine the prevalence of sexual dysfunction during pregnancy and to determine its associated factors.
METHODS: This 6-month cross-sectional study adopted convenience sampling; inclusion criteria were healthy pregnant women, sexually active and living together with their partner for 3 months prior to recruitment into this study. Women who received advice to avoid sexual intercourse, with any medical illness and/or those conceived via assisted reproductive technology were excluded. Participants filled in a questionnaire consisting of demographic details and Malay Version Female Sexual Function Index Questionnaire. Data were analysed using SPSS 24.0; categorical data were analyzed by Chi-square and Fisher exact test.
RESULTS: One hundred pregnant women with a mean age of 31 + 4.31 years old participated. By using the cut-off FSFI score of 26.55, 81 (81%) participants were diagnosed to have sexual dysfunction. The mean FSFI score was 20.41 ± 8.45 (range 2.6-33.5; median 23.6). All the mean FSFI scores of first, second and third trimesters were low with 22.80 ± 10.67, 23.81 ± 7.18 and 18.74 ± 8.43, respectively. The mean score for desire, arousal, satisfaction and pain were significantly lower in the third trimester than earlier gestation. There was a significant difference in the incidence of difficulties in desire, arousal, lubrication, satisfaction and pain between first and second trimester combined, as compared to the third trimester of pregnancy. Trimester of pregnancy was found to have a significant association with the incidence of sexual dysfunction.
CONCLUSION: Sexual dysfunction among pregnant women is a significant burden. Despite being a common health problem, it is often neglected.

Sociocultural factors have been shown to be important influencers of sexual health and sexuality. Hence, the aim of our study was to explore the views and experiences of family medicine trainees regarding female sexual dysfunction (FSD) with a focus on the barriers and facilitators towards the initiation of conversation on this topic. A qualitative study design involving semi-structured focus group discussions (FGDs) was conducted with 19 family medicine trainees in Malaysia. The conceptual framework used was based on the Theory of Planned Behavior. Thematic approach was used to analyze the data. Participants perceived FSD as being uncommon and unimportant. According to our participants, patients often presented with indirect complaints, and doctors were not proactive in asking about FSD. Three main barriers were identified: doctor factors, perceived patient factors, and system factors. Lack of confidence, knowledge, experience, time, and embarrassment were the key barriers identified at the doctors' level. Lack of awareness, among patients regarding FSD, and local cultural and religious norms were the perceived patient barriers. System barriers were lack of time and privacy. Various facilitators, such as continuous medical education and public forums, were suggested as means to encourage family medicine trainees to initiate discussion on sexual matters during consultations. In conclusion, family medicine trainees found it difficult to initiate conversation on FSD with patients. Interventions to encourage conversation on FSD should target this and other identified barriers.

Meanings of Sexuality: Views from Malay Women with Sexual Dysfunction

Muhamad R, Horey D, Liamputtong P, Low WY, Sidi H

Arch Sex Behav, 2019 04;48(3):935-947.
PMID: 30066036 DOI: 10.1007/s10508-018-1228-1

In Malaysia, female sexual dysfunction (FSD) among Malays is common, so understanding the meanings of sexuality becomes crucial, as they can vary with identity, and this may influence each woman's subsequent reaction to sexual experience. In this article, we explore the meanings of sexuality that Malay women had developed throughout their lived experience. This qualitative study, situated within a social cognitive theory and a phenomenological framework, was conducted through in-depth and photograph elicitation interviews with 26 Malay women who had self-reported experiencing FSD. The findings suggest that the meanings of sexuality for these women linked closely with fundamental factors of Malay identity, which is comprised of tradition (Adat), religion (Islam), and language, that all influence gendered roles. Malay women understood sexuality to be sexual intimacy within marriage, privileging their marital role as a "good wife" over their personal rights within a sexual relationship. This understanding of sexuality was reinforced by meanings attributed to procreation, which Malay women linked closely to the purpose of marriage and their role as a "good mother." The findings should provide useful evidence that could be used in sexual health promotions to help reduce FSD and in clinical practice to generate appropriate therapy in Malaysia and elsewhere.

Managing Women with Sexual Dysfunction: Difficulties Experienced by Malaysian Family Physicians

Muhamad R, Horey D, Liamputtong P, Low WY

Arch Sex Behav, 2019 04;48(3):949-960.
PMID: 30238183 DOI: 10.1007/s10508-018-1236-1

Recognizing barriers to managing sexual issues makes it more likely that effective ways to overcome them will be found. In Malaysia, where discussion of sexual issues is taboo, sociocultural factors may influence how physicians manage patients with these types of problems. This article focuses on the challenges encountered by 21 Malay family physicians when women experiencing sexual problems and female sexual dysfunction (FSD) attended their clinics, an uncommon occurrence in Malaysia, despite their high prevalence. This qualitative study employed a phenomenological framework and conducted face-to-face in-depth interviews. Three main barriers to managing women with sexual problems were identified that can hinder assessment and treatment: insufficient knowledge and training; unfavorable clinic environments; and personal embarrassment. Some barriers were associated with physician characteristics but many were systemic. These were further evaluated using social cognitive theory. Professional attitudes appear important as those physicians with an interest in managing women's health seemed to make greater effort to explore issues further and work to gain trust. Physicians who appeared indifferent to the impact of FSD showed greater reluctance to find solutions. Systemic issues included unfavorable clinical settings, lack of training, and lack of local evidence. Any strategy to address FSD needs to be underpinned by appropriate policies and resources.

Fulltext Evolution of diabetes management in the 21st century: the contribution of quality of life measurement in Asians

Goh SG, Rusli BN, Khalid BA

Asia Pac J Clin Nutr, 2015;24(2):190-8.
PMID: 26078234 DOI: 10.6133/apjcn.2015.24.2.04

Diabetes mellitus (DM) is a complex and chronic disease with multiple complications leading to increased mortality and poor quality of life. Current studies have shown that lowering glycosylated haemoglobin (HbA1c) confers protection against microvascular complications. However, with more intensive glucose control to achieve HbA1c of less than 6.5%, there seems to be a significant increased risk of mortality and cardiovascular events. The current recommendation worldwide is for "tailoring" of DM management to risk and also quality of Life (QOL) which is a crucial component in determining the success or failure of DM management. In Asia, DM has become a health crisis but there is a lack of QOL assessment tool that is specific for Asians with wide spectrum of ethnicity, languages, religions and socio-economic differences. In this review, we discuss the evolution of DM management over the decade and the issues pertaining to QOL among people living with diabetes in Asia.

Association of brain-derived neurotrophic factor valine to methionine polymorphism with sexual dysfunction following selective serotonin reuptake inhibitor treatment in female patients with major depressive disorder

Nazree NE, Mohamed Z, Reynolds GP, Mohd Zain S, Masiran R, Sidi H, et al.

Asia Pac Psychiatry, 2016 Dec;8(4):260-268.
PMID: 27787964 DOI: 10.1111/appy.12210

INTRODUCTION: The occurrence of female sexual dysfunction (FSD) in patients with major depressive disorder (MDD) receiving selective serotonin reuptake inhibitors (SSRIs) treatment gives negative impacts on patients' quality of life and causes treatment discontinuation. We aimed to investigate whether genetic polymorphism of identified candidate gene is associated with FSD in our study population.
METHODS: This is a cross-sectional study. A total of 95 female patients with MDD who met the criteria of the study were recruited and were specifically assessed on the sexual function by trained psychiatrists. Patients' DNA was genotyped for BDNF Val66Met polymorphism using real-time polymerase chain reaction.
RESULTS: The prevalence of FSD in this study is 31.6%. In the FSD group, patients with problematic marriage were significantly more frequent compared with patients who did not have problematic marriage (P = 0.009). Significant association was detected in the lubrication domain with BDNF Val66Met polymorphism (P = 0.030) using additive genetic model, with even stronger association when using the recessive model (P = 0.013).
DISCUSSION: This study suggested that there was no significant association between BDNF Val66Met with FSD. However, this polymorphism is significantly associated with lubrication disorder in patients treated with SSRIs.

PMID: 27644611

BACKGROUND: Polycystic ovary syndrome (PCOS) is a combination of chronic anovulation, obesity, and hyperandrogenism and can affect sexual function in women of reproductive age. It is also associated with endometrial cancer. Our aim was to evaluate the frequency and predisposing factors of sexual dysfunction in PCOS patients.

MATERIALS AND METHODS: In this cross-sectional study, 16 married women with a definite diagnosis of PCOS were recruited. Sexual function was assessed in the domains of desire, arousal, lubrication, orgasm, satisfaction and pain using the female sexual function index (FSFI) questionnaire. Patients were also assessed for mental health using the depression, anxiety and stress (DASS-21) questionnaire. Presence of hirsutism was assessed using the Ferriman-Gallwey (FG) scoring system. Demographic data were obtained from patients during in-person interview.

RESULTS: Sexual dysfunction was present in 62.5% of patients with the domains of arousal and lubrication particularly affected (93.8% and 87.5%, respectively). Patients with symptoms of depression and anxiety were significantly more likely to suffer sexual dysfunction than those without these symptoms (p=0.04 and p=0.03 respectively). Patients with stress symptoms reported higher orgasm dysfunction than those without (p=0.02). No significant difference in any of the FSFI score domains was observed between patients with and without hirsutism.

CONCLUSIONS: PCOS patients markedly suffer from sexual dysfunction and therefore it seems appropriate to be screened for intervention. Poor mental health conditions that may be the result of infertility or other complications of PCOS should also be considered as curable causes of sexual dysfunction in these patients.

PMID: 21643001 DOI: 10.1038/aja.2010.135

Sex has always been a taboo subject in Asian society. However, over the past few years, awareness in the field of men's sexual health has improved, and interest in sexual health research has recently increased. The epidemiology and prevalence of erectile dysfunction, hypogonadism and premature ejaculation in Asia are similar in the West. However, several issues are specific to Asian males, including culture and beliefs, awareness, compliance and the availability of traditional/complementary medicine. In Asia, sexual medicine is still in its infancy, and a concerted effort from the government, relevant societies, physicians and the media is required to propel sexual medicine to the forefront of health care.

Systemic sclerosis is a chronic multi-organ autoimmune disease, leading to important clinical and psychological implications. Among organ complications, sexual dysfunction is a major issue for both male and female gender, with high prevalence and great impact on quality of life, although frequently not addressed by both clinicians and patients. While erectile dysfunction is the most common cause of sexual problems in males, genital tract and general physical changes are major contributors to sexual impairment in females. This review presents current state of the art on this topic, discussing published data on presentation, evaluation and therapeutic options.

PMID: 28259255 DOI: 10.1016/S1875-5364(17)30010-9

Eurycoma longifolia (EL) has been well recognized as a booster of male sexual health. Over the past few decades, numerous in vivo animal studies and human clinical trials have been conducted across the globe to explore the promising role of EL in managing various male sexual disorders, which include erectile dysfunction, male infertility, low libido, and downregulated testosterone levels. The aim of the present review is to analyze and summarize the literature on human clinical trials which revealed the clinical significance and therapeutic feasibility of EL in improving male sexual health. This systematic review is focused on the following databases: Medline, Wiley Online Library, BioMed Central, Hindawi, Web of Knowledge, PubMed Central and Google Scholar, using search terms such as "Eurycoma longifolia", "EL", "Tongkat Ali", "male sexual health", "sexual infertility", "erectile dysfunction", "male libido", and "testosterone levels". Notably, only human clinical studies published between 2000 and 2014 were selected and thoroughly reviewed for relevant citations. Out of 150 articles, 11 met the inclusion criteria. The majority of articles included were randomized placebo-controlled trials, multiple cohort studies, or pilot trials. All these studies demonstrated considerable effects of EL on male sexual health disorders. Among them, 7 studies revealed remarkable association between the use of EL and the efficacy in the treatment of male sexual disorders, and remaining 4 studies failed to demonstrate sufficient effects on male sexual health. In summary, there is convincing evidence for the prominence of EL in improving the male sexual health. The review also substantiates the use of current methodology in the development of novel and more rationale natural herbal medicines for the management of male sexual disorders.

The menopausal experience among indigenous women of Sarawak, Malaysia

Syed Alwi SA, Lee PY, Awi I, Mallik PS, Md Haizal MN

Climacteric, 2009 Dec;12(6):548-56.
PMID: 19905907 DOI: 10.3109/13697130902919519

OBJECTIVES:
To document the common menopausal symptoms and quality of life in indigenous women of Sarawak in Malaysia.

METHODS:
A face-to-face interview using the Menopause-specific Quality of Life questionnaire was conducted with 276 indigenous Sarawakian women aged 40-65 years to determine the mean age of menopause and common symptoms (divided into vasomotor, psychosocial, physical and sexual domains) associated with menopause.

RESULTS:
The mean age at menopause of postmenopausal women was 50.78 +/- 2.47 years (range 47.3-58.2 years). The most common symptoms reported were aching in muscles and joints (82.6%), lack of energy (77.5%) and low backache (77.2%). The typical menopausal symptoms of hot flushes, night sweats, sweating and vaginal dryness were experienced by 42.4%, 34.8%, 29.7% and 49.3%, respectively of the women studied. Perimenopausal women (n = 114) experienced the most physical and psychosocial symptoms, while postmenopausal women (n = 102) experienced most sexual symptoms. Perimenopausal and postmenopausal women were reported to suffer more than premenopausal women (p < 0.001) within the four domains of symptoms (vasomotor, psychosocial, physical and sexual).

CONCLUSIONS:
The menopausal symptoms in this study correspond to those in other studies on Asian women but the prevalence of typical and classical menopausal symptoms was lower compared to studies on Caucasian women. The perimenopausal women had the most significant decrease in quality of life, followed by postmenopausal women and premenopausal women. Vasomotor symptoms had a predominant influence on the quality of life.

Female sexual dysfunction post radical cystectomy and urinary diversion

Zahran MH, Fahmy O, El-Hefnawy AS, Ali-El-Dein B

Climacteric, 2016 Dec;19(6):546-550.
PMID: 27649461

OBJECTIVES: To evaluate the impact of radical cystectomy and urinary diversion on female sexual function.
MATERIALS AND METHODS: A Medline search was conducted according to the PRISMA statement for all English full-text articles published between 1980 and 2016 and assessing female sexual function post radical cystectomy and urinary diversion. Eligible studies were subjected to critical analysis and revision. The primary outcomes were the reporting methods for female sexual dysfunction (FSD), manifestations of FSD, and factors associated with FSD, postoperative recoverability of FSD, and awareness level regarding FSD.
RESULTS: From the resulting 117 articles, 11 studies were finally included in our systematic review, with a total of 361 women. Loss of sexual desire and orgasm disorders were the most frequently reported (49% and 39%). Dyspareunia and vaginal lubrication disorders were reported in 25% and 9.5%, respectively. The incidence of sexual dysfunction was 10% in 30 patients receiving genital- or nerve-sparing cystectomy vs. 59% receiving conventional cystectomy.
CONCLUSION: Although female sexual function is an important predictor of health-related quality of life post radical cystectomy and urinary diversion, the available literature is not enough to provide proper information for surgeons and patients.

Grewal GS, Gill JS, Sidi H, Gurpreet K, Jambunathan ST, Suffee NJ, et al.

Compr Psychiatry, 2014 Jan;55 Suppl 1:S17-22.
PMID: 23452905 DOI: 10.1016/j.comppsych.2013.01.009

OBJECTIVE: To determine the prevalence and risk factors of female sexual dysfunction (FSD) among healthcare personnel in selected healthcare facilities in Malaysia.
METHODS: This was a cross-sectional study carried out at three large healthcare facilities that were selected by convenience sampling. Within each facility, stratified random sampling was used to select suitable candidates to participate in the study (n=201). Validated questionnaires were used to assess depression, anxiety, sexual function in women and erectile dysfunction (ED) in their partners.
RESULTS: The prevalence of FSD was 5.5%. Women with sexual dysfunction were more likely to be married longer (OR=4.08; 95% CI; 1.15-4.50), had lower frequency of sexual intercourse (OR=5.00; 95% C; 1.05-23.76) and had a spouse with ED (OR=24.35; 95% CI; 4.55-130.37). Multivariate analysis showed that ED was the strongest predictor for FSD (AOR=27.30; 95% CI; 4.706-159.08).
CONCLUSION: One in eighteen female healthcare personnel suffered from FSD and presence of ED in the partner strongly impacted her sexual function, negatively. The findings highlight the importance of including the male partner in clinical assessment of FSD.

The Neurobiology and Psychiatric Perspective of Vaginismus: Linking the Pharmacological and Psycho-Social Interventions

Kadir ZS, Sidi H, Kumar J, Das S, Midin M, Baharuddin N

Curr Drug Targets, 2018;19(8):916-926.
PMID: 28228081 DOI: 10.2174/1389450118666170222153908

Vaginismus is an involuntary muscle contraction of the outer third of vaginal barrel causing sexual penetration almost impossible. It is generally classified under sexual pain disorder (SPD). In Diagnostic and Statistical Manual, 5th edition (DSM-5), it is classified under the new rubric of Genito-Pelvic Pain/Sexual Penetration Disorder. This fear-avoidance condition poses an ongoing significant challenge to the medical and health professionals due to the very demanding needs in health care despite its unpredictable prognosis. The etiology of vaginismus is complex: through multiple biopsycho- social processes, involving bidirectional connections between pelvic-genital (local) and higher mental function (central regulation). It has robust neural and psychological-cognitive loop feedback involvement. The internal neural circuit involves an inter-play of at least two-pathway systems, i.e. both "quick threat assessment" of occipital-limbic-occipital-prefrontal-pelvic-genital; and the chronic pain pathways through the genito-spinothalamic-parietal-pre-frontal system, respectively. In this review, a neurobiology root of vaginismus is deliberated with the central role of an emotional-regulating amygdala, and other neural loop, i.e. hippocampus and neo-cortex in the core psychopathology of fear, disgust, and sexual avoidance. Many therapists view vaginismus as a neglected art-and-science which demands a better and deeper understanding on the clinico-pathological correlation to enhance an effective model for the bio-psycho-social treatment. As vaginismus has a strong presentation in psychopathology, i.e. fear of penetration, phobic avoidance, disgust, and anticipatory anxiety, we highlighted a practical psychiatric approach to the clinical management of vaginismus, based on the current core knowledge in the perspective of neuroscience.

Serotonin Selective Reuptake Inhibitors (SSRIs) and Female Sexual Dysfunction (FSD): Hypothesis on its Association and Options of Treatment

Rappek NAM, Sidi H, Kumar J, Kamarazaman S, Das S, Masiran R, et al.

Curr Drug Targets, 2018;19(12):1352-1358.
PMID: 28025939 DOI: 10.2174/1389450117666161227142947

Sexual dysfunctions are commonly seen in women on selective serotonin reuptake inhibitors (SSRIs). The complexities of female sexual functioning are reflected through modulation of inter- playing factors like the neuropsychophysiological factors, inter-personal and relationship issue, psychiatric co-morbidities and physical disorder. The incidence of SSRIs-induced FSD is difficult to estimate because of the potential confounding effects of SSRIs, presence of polypharmacy, marital effect, socio-cultural factors and due to the design and assessment problems in majority of the studies. The exact mechanism of FSD-induced SSRIs is unknown. It has been postulated that although SSRIs may modulate other neurotransmitter system such as nitric oxide (NO), noradrenergic and dopamine in inducing FSD. In the present review, we highlight current evidence regarding potential mechanism of SSRIs in causing FSD, which include low sexual desire (low libido), arousal difficulties (lack of lubrication), and anorgasmia. The specific association of FSD to SSRI use, has not been ellucidated. The relationship is dose-dependent, and may vary among the groups with respect to mechanism of serotonin and dopamine reuptake, induction of release of prolactin from the pituitary gland, anticholinergic side-effects, inhibition of NO synthesis and emotional-memory circuit encryption for sexual experiences. Various interventional strategies exist regarding the treatment of SSRI-induced FSD and this includes tolerance, titration dosage, substitution to another antidepressant drug and psychotherapy. There is a need of better understanding of SSRIs-induced FSD for better treatment outcome.

Fulltext The SAD-MEN questionnaire: a new and reliable questionnaire for assessing sexual dysfunction in Asians with diabetes

Chung CM, Lu MZ, Wong CY, Goh SG, Azhar MI, Lim YM, et al.

Diabet Med, 2016 May;33(5):674-80.
PMID: 26202696 DOI: 10.1111/dme.12864

AIM: The aim of this study is to construct a new tool for the assessment of sexual dysfunction among men with diabetes that is valid and reliable across different ethnicities, languages and socio-economic backgrounds in South East Asia.
METHODS: Focus group interviews were conducted to determine the construct of the questionnaire. Content and face validity were assessed by a panel of experts. A pilot study was conducted to validate the Sexual Dysfunction in Asian Men with Diabetes (SAD-MEN) questionnaire in English and Malay. The International Index of Erectile Function-5 (IIEF-5) was used for comparison. Construct validity was assessed using exploratory factor analysis, reliability was determined using Cronbach's α (> 0.700), and test-retest reliability using Spearman's rank correlation coefficient.
RESULTS: The SAD-MEN questionnaire yielded moderate face and content validity, with high reliability as shown by Cronbach's α values of 0.949 for sexual performance and 0.775 for sexual desire for the English version.
