    The Sundaland species of the genus Dysphaea were studied using molecular and morphological methods. Four species are recognized: D. dimidiata Selys, D. lugens Selys, D. ulu spec. nov. (holotype ♂, from Borneo, Sarawak, Miri division, Upper Baram, Sungai Pejelai, Ulu Moh, 24 viii 2014; deposited in RMNH) and D. vanida spec. nov. (holotype ♂, from Thailand, Ranong province, Khlong Nakha, Khlong Bang Man, 12-13 v 1999; deposited in RMNH). The four species are described and illustrated for both sexes, with keys provided. The type specimens of the four Dysphaea taxa named by E. de Selys Longchamps, i.e. dimidiata, limbata, semilimbata and lugens, were studied and their taxonomic status is discussed. Lectotypes are designated for D. dimidiata and D. limbata. D. dimidiata is recorded from Palawan (the Philippines) for the first time. A molecular analysis using three markers (COI, 16S and 28S) is presented. This includes specimens of three Sundaland species of the genus (D. lugens missing) and two congeners from other regions (D. basi-tincta and D. gloriosa). Notes and photographs of the male holotype of D. walli Fraser (from Maymyo, Burma) are provided.

    We describe unique reproductive features of two threatened Galliformes species, the Malaysian peacock-pheasant (Polyplectron malacense) and Bornean peacock-pheasant (P. schleiermacheri). These features pose challenges to successful captive breeding to build up sustainable populations for conservation purposes. Single egg clutches in both species mean that reproductive rates are low and population increase is slow. The very rounded eggs of Bornean Peacock-pheasant cause difficulties for egg orientation in incubators. Single chicks with special requirements are poorly suited to rearing by broody bantams and successful husbandry requires increased human time, commitment, and skills.

    In the present study, researchers explored attitudes toward midlife crises, experience with midlife crises, help-seeking, and needs among multi-ethnic Malaysian women. A total of 14 focus group discussions were conducted with 89 Malaysian women of different ages and socioeconomic backgrounds. Women expressed concern over physical aging and decline in their physical functional health. Having a midlife crisis was frequently reported. Issues that were frequently reported to trigger a midlife crisis, such as empty nest syndrome, impact of aging on sexual and reproductive function, extended parenthood, caring for aging or ill parents, and career challenges were noted by the study participants (listed here in order of most to least frequently reporting of these themes across the group discussions). Overall, these issues were associated with attitudes about aging. A comparatively less open attitude toward sexual attitudes and help-seeking for sexual problems were found among the Malay and Indian women. This may imply that intervention to increase positive attitudes concerning both sexuality and help-seeking intentions should be culturally specific. The use of religious coping for comfort and consolation was frequently reported; therefore, those providing midlife crisis prevention and intervention programs should consider involving faith-based interventions in the Malaysian setting.

    Cervical cancer remains one of the leading causes of cancers in women from Indonesia, Malaysia, the Philippines, Thailand and Vietnam. High-risk human papillomavirus (HPV) types, particularly HPV-16 and 18, are consistently identified in cervical cancer cases regardless of geographical region. Factors that have been identified to increase the likelihood of HPV exposure or subsequent development of cervical cancer include young age at first intercourse, high parity and multiple sexual partners. Cervical cancer screening programs in these countries include Pap smears, single visit approach utilizing visual inspection with acetic acid followed by cryotherapy, as well as screening with colposcopy. Uptake of screening remains low in all regions and is further compounded by the lack of basic knowledge women have regarding screening as an opportunity for the prevention of cervical cancer. Prophylactic HPV vaccination with the quadrivalent vaccine has already been approved for use in Malaysia, the Philippines and Thailand, while the bivalent vaccine has also been approved in the Philippines. However, there has been no national or government vaccination policy implemented in any of these countries.

    Entomological surveillance was conducted in order to determine the abundance and to evaluate any changes of biological vectors or ecology, especially in the dengue outbreak areas. The abundance and breeding preference of Aedes albopictus and Aedes aegypti were conducted in selected dengue outbreak localities in three states of peninsular Malaysia namely Selangor, Federal Territory of Kuala Lumpur, and Penang Island using ovitraps and larval survey method. It was determined that Ae. albopictus was predominant in most of the localities and found to breed more outdoor than indoor. A wide range of breeding foci were recorded in this study. It was also determined that ovitrap method was more effective to detect the presence of Aedes mosquitoes when the larval survey was at low rate of infestation. The abundance of Ae. albopictus in dengue outbreak localities emphasis that the vector control programme should also target this species together with the primary dengue vector, Ae. aegypti.

    The natural and artificial mating of laboratory bred Aedes albopictus and transgenic Aedes aegypti RIDL-513A-Malaysian strain was conducted. The experiment consisted of crossmating of homologous Ae. aegypti RIDL female symbol X Ae. aegypti RIDL male symbol and reciprocal Ae. aegypti RIDL female symbol X Ae. albopictus WT male symbol. The other set comprised homologous Ae. albopictus WT female symbol X Ae. albopictus WT male symbol and reciprocal Ae. albopictus WT female symbol X Ae. aegypti RIDL male symbol. This study demonstrated that reproductive barriers exist between these two species. Cross insemination occurred between A. albopictus male and Ae. aegypti female and their reciprocals. There was 26.67% and 33.33% insemination rate in Ae. aegypti RIDL female cross-mating with A. albopictus WT male and Ae. albopictus female cross-mating with Ae. aegypti RIDL male, respectively. There was 0% hatchability in both directions of the reciprocals. There was also no embryonation of these eggs which were bleached. Although none of the female Ae. albopictus WT was inseminated in the cross-mating with Ae. albopictus WT female symbol X Ae. aegypti RIDL male symbol, a total of 573 eggs were obtained. The homologous mating was very productive resulting in both high insemination rate and hatchability rates. Generally there was a significantly higher insemination rate with artificial mating insemination of homologous than with artificial mating of reciprocal crosses. Interspecific mating between Ae. aegypti RIDL and Ae. albopictus wild type was not productive and no hybrid was obtained, indicating absence of horizontal transfer of introduced RIDL gene in Ae. aegypti to Ae. albopictus.

    We examined the growth, reproduction, rutting behavior, and health status of sambar deer (Cervus unicolor brookei) in secondary Acacia mangium plantation. The data were collected over 11 years from a breeding herd of 21 stags and 33 hinds in Sabal Forest Reserve, Sarawak, Malaysia. Brody's growth model of the pooled data is Y t  = 148.56 (1 - 0.98e(-0.023t)), which estimates that maximum weights of adults are 184 and 115 kg for males and females respectively. Sambar deer are nonseasonal breeders with the breeding peak in February. Although the earliest age at which a female reached sexual maturity was 11 months, the mean age was 23 ± 7 months. Mean age of first fawning was 32 ± 8 months. Mean gestation period was 259 ± 12 days (n = 82). Stags shed antlers mostly between March and July. Velvet hardens at 103 ± 27 days (n = 23), and velvet harvesting is best at 7-9 weeks when antler length is 25-30 cm. Sambar deer are suitable as a farm species in forest plantations and have a vast potential to uplift rural living standards.

    We conducted the world's first experiments under semi-field conditions (ACL-2 field house) to assess the mating competitiveness of genetically sterile RIDL male mosquitoes (513A strain). The field house is a state-of-the-art, fully-contained trial facility, simulating the living space for a household of 2-4 people in Peninsular Malaysia. Ten genetically sterile RIDL male A. aegypti mosquitoes competed with ten wild type males inside this field house to mate with ten wild type females. Hatched larvae from mated females were screened under a fluorescent microscope for genetic markers to determine if they were fathered by RIDL male or wild type male, and all results were cross-checked by PCR. Two such experiments were conducted, each repeated sufficient number of times. All strains were on a Malaysian lab strain background for the first experiment, while the RIDL males alone were on a recently-colonised Mexican strain background for the second experiment. A total of 52 % of the matings were with RIDL males in the first experiment, while 45 % of the matings were with RIDL (Mexican) males in the second experiment. Statistically, this is not significantly different from 50 % of the matings expected to take place with RIDL males if the latter were as competitive as that of the wild type males. This shows that A. aegypti RIDL-513A has excellent mating competitiveness under semi-field conditions, verifying earlier trends obtained in small lab cages. We also observed high mating compatibility between recently-colonised Mexican RIDL males and lab-reared Malaysian wild type females.

    Cigarette smoking is associated with sexual dysfunction and impaired fertility in males. The aim of this study was to determine the potential protective effect of honey against the toxic effect of cigarette smoke (CS) on sexual behavior and fertility of male rats. Thirty-two adult Sprague-Dawley rats were randomly divided into four groups (8 rats/group) as control, honey (H), CS and H plus CS (H + CS) groups. Rats in control and CS groups received oral administration of distilled water daily while rats in H and H + CS groups received honey (1.2 g/kg body weight/day) by oral gavage. Rats in CS and H + CS groups were also exposed to CS for 8 min 3 times/day. From 10 to 13 weeks of treatment, each male rat was cohabited with 3 untreated female rats for sexual behavioral and reproductive performance studies. Honey significantly increased the percentages of rats achieving intromission and ejaculation as well as increased mating and fertility indexes of male rats exposed to CS. Thus, honey has a protective effect against CS-induced impaired sexual behavior and fertility in male rats.

    According to neurohormonal theory, prenatal androgens are key determinants of sexual orientation. As a reputed marker for prenatal androgens, the 2D:4D finger length ratio has been used in more than a dozen studies to test the hypothesis that prenatal androgens influence sexual orientation. Findings have been very inconsistent.

    INTRODUCTION: Despite the high prevalence of sexual dysfunction among male schizophrenia patients, there is still a paucity of research on this area.
    AIMS: The study aims to determine the prevalence of sexual dysfunction and any association between male patients with schizophrenia in remission and the sociodemographic profile, medication, depression, anxiety, psychopathology of illness, body mass index, and waist circumference.
    METHODS: A cross-sectional study with nonprobability sampling method was conducted in a psychiatric outpatient clinic in Taiping Hospital (Perak, Malaysia) over a 7-month period. A total of 111 remitted male schizophrenia patients were recruited. The validated Malay version of the International Index of Erectile Function (Mal-IIEF-15) was administered to the patients and assessed over 4-week duration in the domains of erectile function, orgasmic function, sexual desire, intercourse satisfaction, and overall satisfaction. Logistic regression analysis was employed.
    MAIN OUTCOME MEASURES: Prevalence and associated factors for sexual dysfunction in each domain are the main outcome measures.
    RESULTS: All five domains of sexual functioning in patients showed a high prevalence of dysfunction ranging from 78.4% to 97.1% with orgasmic dysfunction being the least impaired and intercourse satisfaction the worst impaired. Among the domains, only orgasmic dysfunction was significantly associated with race, i.e., Chinese at lower risk for impairment than the Malays (OR = 0.23; 95% CI: 0.07, 0.76; P = 0.018); education, i.e., patients with education higher than primary level were at higher risk for dysfunction (OR = 6.49; 95% CI: 1.32, 32.05; P = 0.022); and Positive and Negative Syndrome Scale (PANSS)-positive subscale, i.e., higher PANSS-positive score was a protective factor for orgasmic dysfunction (OR = 0.54; 95% CI: 0.33, 0.89; P = 0.015).
    CONCLUSIONS: The prevalence of sexual dysfunction was generally high. Malay patients and those with education higher than primary level were at higher risk for orgasmic dysfunction whereas higher PANSS-positive score was protective against the impairment. The high rate of sexual dysfunction in schizophrenia patients warrants a routine inquiry into patients' sexuality and the appropriate problems being addressed.

    Khat (Catha edulis) is an evergreen tree/shrub that is thought to affect sexual motivation or libido. Its positive effect on sexual desire is more frequently observed in females than in males and occurs when khat is chewed. Thus, khat's effects on sexual behavior may depend on the release mode of its active constituent.

    INTRODUCTION: Sexual problems are common in the general population. Studies have shown that most of these sexual problems are related to their social lives, medical illnesses, and psychological status. Among the sexual problems in men, premature ejaculation (PE) is one of the most frequent, yet it is the least well-understood of the sexual dysfunctions of men.
    AIM: To determine the prevalence of sexual problem particularly PE and erectile dysfunction (ED) among people living in urban areas and to investigate the characteristics associated with these sexual problems in a Malaysian population.
    MAIN OUTCOME MEASURE: The PE which is defined as an intravaginal ejaculation latency time less than 2 minutes was assessed in the ED and non-ED group.
    METHODS: The Hospital Anxiety and Depression scale is used as a measure of the psychological status [30]. The ED status was assessed using the International Index of Erectile Function questionnaire.
    RESULTS: The prevalence of self-reported sexual problems for ED and PE were 41.6% and 22.3%, respectively. In those subjects with ED, 33.5% reported to have PE. Of the total of 430 subjects, anxiety was present in 8.1%, while depression was 5.3%. The prevalence of PE accounted for 25% anxiety and 14.6% for depression respectively in the population. EDs were associated with diabetes and hypertension (OR [95% CI]: 5.33 [2.33, 10.16], 3.40 [1.76, 6.57], P < 0.05), respectively, while factors associated with PE were anxiety and depression (OR [95% CI]: 1.29 [0.68, 2.45], 1.39 [0.69, 2.78]), respectively.
    CONCLUSION: Prevalence of ED is associated with medical symptoms such as diabetes and hypertension and a rise in the prevalence of age while psychological distress such as anxiety and depression also contribute to a higher PE rate.

    INTRODUCTION: There have been limited multiregional studies in Asia examining the parameters of men's general and sexual health and quality of life in the general population vs. those in clinical cohorts of patients with erectile dysfunction (ED).
    AIMS: The aims of the Asian Men's Attitudes to Life Events and Sexuality (Asian MALES) study were to investigate the prevalence of ED, associated health conditions, and ED treatment-seeking patterns in the general male population in five regions of Asia (China, Japan, Korea, Malaysia, and Taiwan).
    MAIN OUTCOME MEASURE: Standardized questionnaire previously used in a similar multiregional study and modified to ensure culturally appropriate content for Asia.
    METHODS: Phase I of the study involved 10,934 adult men, aged 20-75 years, who were interviewed using the standardized questionnaire. Phase II of the study involved men with self-reported ED recruited from Phase I and via physician referral, invitations in general practitioner offices, and street interception (total Phase II sample, N = 1,209).
    RESULTS: The overall prevalence of self-reported ED in the Phase I study population was 6.4%. ED prevalence varied by region and significantly increased with age (P < 0.01). Men with ED reported significantly greater rates of comorbid illness (P < 0.0001) and a reduced quality of life (P = 0.0001), compared with men without ED. Phase II of the study revealed that fewer than half of men with self-reported ED had sought treatment for their problem. Men were more likely to seek help for erection difficulties from Western doctors than from traditional medicine practitioners (P = 0.0001). A man's partner/spouse was the most common influencer of treatment seeking in all regions except Malaysia.
    CONCLUSION: The findings confirm those of existing research on ED in both Asian and non-Asian males: ED is a prevalent condition; the prevalence of ED increases with age and is strongly associated with comorbid conditions; and the majority of men have never sought treatment for their condition. This study highlights a substantial need for the evaluation and treatment of ED in Asian men.

    BACKGROUND: Erectile dysfunction (ED) is a common problem among men across the world. It is usually multifactorial in origin. Behavioral factors can be related to the development of ED and related to many other chronic diseases. It impacts not only the sexual function but also the psychology and their overall quality of life.

    AIM: To determine the association of the behavior factors in relation to ED and to identify the risk and protective factors.

    METHOD: A systematic review search based on Preferred Reporting Items for Systematic Reviews and Meta-Analysis was conducted. The primary databases PubMed, PlosOne, Oxford Academic, SCOPUS, and Ovid were accessed using specific keyword searches. Quality of articles was assessed by using Newcastle-Ottawa Assessment Scale according to the study design.

    OUTCOME: Evaluation of the relationship between behavioral factors and ED.

    RESULTS: 24 studies were identified from the 5 databases which met the predetermined criteria. Overall, the study population include adult male age between 18 and 80 years. The sample size of the studies ranges from 101 to the largest sample size of 51,329. Smoking, alcohol, and drugs usage are found to be risk factors for ED. Meanwhile, dietary intake, physical activity, and intimacy are the protective factors for ED.

    CLINICAL IMPLICATION: The findings from this review may aid clinicians to aim for early detection of ED by screening their risk factors and providing early treatment. This can also be used to promote awareness to the community on the sexual health and factors that can affect their sexual function.

    STRENGTH & LIMITATION: This study looks at all types of behavioral factors that may affect ED; however, there was a substantial heterogeneity detected across the selected study factors. Furthermore, the lack of PROSPERO registration is also a limitation in this study.

    CONCLUSION: Overall, smoking, dietary intake, alcohol consumption, drugs, and physical activities are modifiable risk factors for ED in men. Therefore, it is crucial to promote healthy lifestyle and empower men to prevent ED and early detection of ED for early treatment. Sivaratnam L, Selimin DS, Abd Ghani SR, et al.
