    A survey was conducted to assess student's sexual knowledge and attitudes using a questionnaire based on the Sex Knowledge and Attitude Test (SKAT-II) to compare medical and nursing students with students (non-medical/nursing) who registered for a sexual health course. 85 Sexual Health, 115 medical and 81 nursing students voluntarily participated in the survey. This study showed that all the student groups showed relatively low scores in knowledge. Furthermore, average knowledge scores differed significantly between the three student groups with medical students scoring highest and nursing students lowest. Besides student groups, several other factors were found to be significantly associated with Knowledge score namely, race, religion, age, perception of the importance of religion and the extent to which religious beliefs influence sexual attitudes. Furthermore, multivariate statistical analyses showed that among these factors, student group, race/religion and religious importance were significant predictors of sexual knowledge. Specifically, being a medical student was associated with higher scores relative to a non-medical student, being a Malay student was independently associated with a lower average score compared to other races, and perceiving religion as extremely important was associated with a lower score.

    This paper examines data on the sexual activities of 1,200 Malaysian adolescents aged 15-21 years based on a probability household sampled survey carried out in Kuala Lumpur in 1986. Sexual behaviours like premarital sexual intercourse, contraceptive usage and masturbation were presented. Of the 1,181 unmarried respondents, 9% (105) reported having had sexual intercourse; males were significantly more experienced compared to females. Older age groups were also found to be more sexually active than the younger ones. Among those who had experience dating (n = 521), 20% (105) have experienced sexual intercourse, 44% (228) have kissed and necked, and 35% (183) have experienced petting, while 24% (130) have had no physical intimacies. Poor use of contraception was also revealed. The most commonly used were condoms, oral contraceptives and withdrawal. With regard to masturbation, males begin this practice relatively earlier than females. Almost half of those who indulged in masturbation were worried by the act, especially the females. Implications of the findings are discussed.

    Despite the wide accessibility to internet, pornography activities among youths are not well described in conservative countries like Malaysia. This study aimed to determine the prevalence, elicit gender differences and identify associated factors of pornographic exposure including perceived realism among college students. This cross-sectional study was conducted among students aged 18 to 25 years from seven colleges in Penang, Malaysia. A self-administered questionnaire was used to obtain data on socio-demographic characteristics, pornography exposure, pattern of use, sexual exposure and perceived realism. Among 986 participants, the prevalence of lifetime pornography exposure was 74.5%. More males (71.7%) were exposed to pornography, had started at earlier age, were frequent users and using the internet alone at home (p

    BACKGROUND: Previous studies show that there is a changing trend of sexual and reproductive behaviour among youth and this requires more attention and awareness especially on sexually transmitted diseases (STD). This study was carried out to evaluate the knowledge, attitude and practice of sexually transmitted diseases among selected inmates of women shelter homes.

    METHODS: A cross-sectional study was carried out by involving 60 participants whom aged in between 13 to 25 years old. The questionnaires were developed in 'Bahasa Melayu' and it has been anonymous guided questionnaires.

    RESULTS: The result showed that the mean age of the participants was 17.9 years old and most of the participants have completed secondary school (91.7%). Overall, the level of knowledge of participants on STDs were classified into three groups; 'high knowledge' (33.3%), 'medium knowledge' (35.0%) and 'low knowledge' (31.7%). The majority have heard of HIV/AIDS (95%) but with respect to other STDs was less well known. Whereas, the mean score for attitude was 23.1 out total 25. Their knowledge level was not influenced by their age (p = 0.61) and socio-economic status (p = 0.85). However, their attitude was influenced by their age (p sexuality contradicts it especially on contraceptive use and pre-marital sex.

    The Sumatran rhinoceros (Dicerorhinus sumatrensis) is on the verge of extinction in Malaysia. At the Sumatran rhinoceros Conservation Centre in Sungai Dusun, the reproductive behaviour of two female and two male rhinoceroses were studied for 8-10 months during attempts to breed them in captivity. Due to the paucity of scientific information on the reproductive biology of the Sumatran rhinoceros, this study was conducted to obtain information on the reproductive behaviour of this species. The male rhino was introduced to a female rhino in the morning for 1-2 h daily in order to observe for behavioural oestrus. Observations were made on the signs of oestrus and mating behaviour. Oestrus was determined by receptivity towards the male and lasted about 24 h. Common signs of oestrus were an increase in frequency of urine spraying, tail raising or swinging, anogenital and other contacts. Although the males exhibited mounting, the inability of the male to achieve intromission was poor. The study demonstrated that the pattern of courtship and copulation of the captive Sumatran rhinos were comparable with those of other rhino species, reported previously by other scientists and flehmen reflex was also exhibited by the male Sumatran rhinos. In a captive breeding programme, it is recommended that only an oestral female is introduced into a male enclosure due to the male solitary behaviour and to avoid serious injuries inflicted onto the females.

    Pregnancy among unmarried women may have negative social and health implications in Malaysia. The number of pregnancies among unmarried women has increased in Malaysia, but the socio-demographic profile of these women is unclear. This study aims to evaluate the characteristics of unmarried pregnant women and the factors associated with unmarried pregnancies among young women in Malaysia. We conducted a cross sectional study at six hospitals and six women's shelters in Peninsular Malaysia during 2011-2012. Unmarried pregnant women were compared with married pregnant women. Participants were interviewed using a structured questionnaire asking for socio-demographic data, family background, risky sexual behavior, social support and pregnancy details. A total of 484 women (239 unmarried and 245 married) were included in the study. Most unmarried subjects were adolescents, from urban areas, from a low socioeconomic group, and lived with parents prior to pregnancy. Age (OR=0.67; 95% CI: 0.61-0.74), studying status (OR=17.33; 95% CI: 2.65-113.19), alcohol use (OR=40.46; 95% CI: 2.51-652.38) exposure to pornographic material (OR=13.48; 95% CI: 3.24-56.01), contraceptive use (OR=0.20; 95% CI: 0.08-0.51), and social support (OR=0.90; 95% CI: 0.86-0.94) were all associated with unmarried pregnancy. These factors need to be considered when.designing an intervention program.

    Illicit drug use among adolescents has become a public health issue in Malaysia. This study was from the Global School-Based Student Health Survey (GSHS) and aimed to determine the prevalence of and factors associated with illicit drug use among school-going adolescents in Malaysia. A 2-stage stratified cluster sampling method was used and data were collected via a self-administered questionnaire. A total of 25 507 students participated in the study. The prevalence of adolescents who ever used illicit drugs was 1.7%. Adolescents who ever used illicit drugs were associated with current smoking (adjusted odds ratio [aOR] = 6.99; 95% CI = 5.19, 9.40), current alcohol use (aOR = 4.63; 95% CI = 3.43, 6.26), ever having sex (aOR = 4.76; 95% CI = 3.54, 6.41), truancy (aOR = 1.43; 95% CI = 1.07, 1.90), lack of peer support (aOR = 1.47; 95% CI = 1.07, 2.03), and lack of parental monitoring (aOR = 1.71; 95% CI = 1.22, 2.39). Public health intervention should be addressed to prevent illicit drug used among adolescents.

    INTRODUCTION: Chlamydia trachomatis is one of the most common sexually transmitted diseases (STDs) globally. However, data on its prevalence and risk factors in Malaysia is still scarce.

    OBJECTIVE: We aimed to identify the prevalence and risk factors of genitourinary C.trachomatis infection among patients attending STD clinics in northern Peninsular Malaysia.

    METHODS: A hospital-based cross-sectional study was conducted in STD clinics of Hospital Pulau Pinang and Hospital Sultanah Bahiyah, Kedah from January to November 2014. Participants were individually interviewed using a structured data collection form followed by a physical examination and laboratory tests. Nucleic Acid Amplification Test (NAAT) was used to detect C.trachomatis infection. Analysis was carried out using SPSS Version 15.

    RESULTS: Eighty-three sexually active patients were enrolled, consisting of 51 males and 32 females. The median age was 28.0 years. In general, 32.5% patients were asymptomatic, the remaining presented with genital discharge (41.0%), genital warty lesion (25.3%), genital ulcer (13.3%), dysuria (13.3%), dyspareunia (2.4%), urine hesistancy (1.2%) and genital swelling (1.2%). The prevalence of genitourinary C.trachomatis infection was 21.7% in the study population; 17.6% in males and 28.1% in females. Among the infected females, 44.4% were pregnant. Of those infected 56.6% did not show any symptoms of genital infection, and 77.8% were aged between 18 and 30 years, of which most were females. Among newly diagnosed HIV patients, the prevalence was 14.3%. From multivariable logistic regression analysis, age under 28 years, being married and engagement in oral sex had significantly increased odds of C.trachomatis infection.

    CONCLUSIONS: C.trachomatis infection was common among patients attending STD clinics in northern Penisular Malaysia especially in the younger age groups. Majority of the infected patients were asymptomatic.

    Low sexual desire (SD) is not life threatening, but its negative impact on the quality of life and intimacy of a relationship among the patients on methadone maintenance therapy (MMT) is significant. This cross-sectional study involved 183 men on MMT who were interviewed and who completed the Malay version of the SDI-2 (SDI-2-BM), the Malay version of the self-rated Montgomery-Asberg Depression Rating Scale (MADRS-BM) and World Health Organization Quality of Life-BREF Scale (WHOQOL-BREF) questionnaires. Findings showed 32.8% ( n = 60) participants had low SD. Those who were older, had sexual partners, and were smokers achieved lower scores in both dyadic SD (≤24) and solitary SD (≤6), and suffered lower quality of life in their social relationship. MMT is very cost-effective in rehabilitating opioid dependence; however, as clinicians, we need to address and manage the issues of low SD and depression among patients on MMT, especially the older men.

    Drawing on the lived experiences of the Pengkids and their girlfriends in the deprived district of the capital city of Malaysia, Kuala Lumpur, this article examines transgender practices and women's same-sex desires within the local contexts of urbanization and political Islam. This article questions the assumed marginal positions of transgender practices and same-sex desires in society, and provides a nuanced understanding of the politics of identity, gender, sexuality and religion involved in a Muslim country. While the Muslim-Malay sexual minorities are increasingly subjected to the threats of moral policing in Malaysia, Pengkid has become a new identity marker for the marginalized sexual subject framed by the Islamic discourse of this country.

    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.

    BACKGROUND: The increasing trend of premarital sexual experience and unintended pregnancies in Malaysia warrants sustained and serious attention. The sensitivities of sex-related issues in a Muslim-majority country create various types of barriers to sexual and reproductive health information, support and practices. This study aims to gain understanding of knowledge, attitudes and behaviours of young women in Malaysia concerning reproductive, contraception and premarital sexual practices.
    METHODS: A cross-sectional study was performed, using an anonymous self-administered questionnaire carried out among 1695 female university students in a public university in Malaysia.
    RESULTS: Respondents had low scores for knowledge of reproduction and pregnancy (median=4, of maximum score 10), contraceptive uses (median=6, of maximum score 16) and contraceptive availability (median=3, of maximum score 13). The majority of women surveyed do not have liberal values in relation to premarital sexual behaviour (median=37, of maximum 40); higher scores on this scale corresponded to opposing premarital sex. The multivariate analyses showed that ethnic group was the strongest correlate of knowledge and attitude scores; being of Malay Muslim ethnicity was associated significantly with lower knowledge scores and premarital sex permissiveness. Other significant correlates were year of study, maternal occupational groups, level of religious faith, dating status and urban-rural localities. Level of premarital sex permissiveness was inversely correlated with reproduction and pregnancy knowledge score, and contraceptive knowledge scores.
    CONCLUSION: Reproductive health knowledge and attitudes were intricately linked to religious values and cultural norms differences surrounding sexual issues.

    Males of certain Dacini fruit flies are strongly attracted to, and feed upon, plant secondary compounds such as methyl eugenol, raspberry ketone and zingerone. The consumed lure is generally found to induce physiological and behavioural changes that enhance the mating performance of lure-fed males. Male Bactrocera jarvisi respond strongly to zingerone from a young age, but only weakly respond to raspberry ketone. We hypothesized that this selective lure-response would be reflected in the physiological importance of the lure to the fly. We found that zingerone feeding by young males resulted in significantly greater mating success in competitive mating trials with lure-deprived flies, but the mating advantage was lost in older males. Lure dosage had a significant effect on the duration of the mating advantage, for example when fed 20 µg of zingerone, the advantage lasted only 1 day post-feeding, but when fed of 50 µg zingerone the advantage lasted 7 days. Raspberry ketone feeding did not confer any mating advantage to males except at one dosage (50 µg) for 1 day after feeding. When given a choice, B. jarvisi females preferred to mate with zingerone-fed versus to raspberry ketone-fed males. This study revealed lure, dosage and age of fly at time of lure administration are all important factors for maximising lure-enhanced fruit fly mating performance. These findings contribute to a better theoretical understanding of the evolution of fruit fly-lure interactions and may help improve fruit fly pest management via the Sterile Insect Technique through semiochemical-mediated enhancement of sterile male mating performance.

    The Artocarpus fruit fly, Bactrocera umbrosa (Fabricius) (Diptera: Tephritidae), is an oligophagous fruit pest infesting Moraceae fruits, including jackfruit (Artocarpus heterophyllus Lamarck), a fruit commodity of high value in Malaysia. The scarcity of fundamental biological, physiological and ecological information on this pest, particularly in relation to behavioural response to phytochemical lures, which are instrumental to the success of many area-wide fruit fly control and management programmes, underpins the need for studies on this much-underrated pest. The positive response of B. umbrosa males to methyl eugenol (ME), a highly potent phytochemical lure, which attracts mainly males of many Bactrocera species, was shown to increase with increasing age. As early as 7 days after emergence (DAE), ca. 22% of males had responded to ME and over 50% by 10 DAE, despite no occurrence of matings (i.e. the males were still sexually immature). Male attraction to ME peaked from 10 to 27 DAE, which corresponded with the flies' attainment of sexual maturity. In wind-tunnel assays during the dusk courtship period, ME-fed males exhibited earlier calling activity and attracted a significantly higher percentage of virgin females compared with ME-deprived males. ME-fed males enjoyed a higher mating success than ME-deprived males at 1-day post ME feeding in semi-field assays. ME consumption also promotes aggregation behaviour in B. umbrosa males, as demonstrated in wind-tunnel and semi-field assays. We suggest that ME plays a prominent role in promoting sexual communication and enhancing mating performance of the Artocarpus fruit fly, a finding that is congruent with previous reports on the consequences of ME acquisition by other economically important Bactrocera species.

    After pharmacophagy of methyl eugenol (ME), males of Bactrocera carambolae (Diptera: Tephritidae) produced (E)-coniferyl alcohol (CF) along with its endogenously synthesized pheromonal compounds. CF was shown to be released into the air by the ME-fed males only during the courtship period at dusk and attracted significantly more males and females than the ME-deprived males in wind tunnel assays. However, earlier onset of sexual attraction and a higher mating success were observed only in the wind tunnel and field cage assays on the third day posttreatment of ME. Field cage observations on the male-to-male interaction indicated that the ME-deprived males did not exhibit aggregation behavior, but that ME feeding promoted aggregation behavior in B. carambolae. Field cage observations revealed that the ME-deprived males were not only attracted to the ME-fed males, but also appeared to feed on their anal secretions. The secretions were subsequently confirmed to contain CF along with endogenously produced pheromonal compounds. Results obtained for B. carambolae were compared to those previously obtained from its sibling species, Bactrocera dorsalis, and are discussed in light of species advancement in fruit fly-plant relationships.
