    BACKGROUND: International students make up an increasing proportion of university students in Australia. Research suggests that they have poor sexual health knowledge compared with local students.
    METHODS: Thematic analysis was undertaken on focus groups carried out at the University of Adelaide (South Australia), with 21 female international students from Malaysia and China.
    RESULTS: Four themes were identified: poor sexual health knowledge; complex attitudes about premarital sex; difficulty accessing sexual health information, and poor understanding the role of general practitioners in this area; and ideas about future education.
    DISCUSSION: Participants believed that international students have insufficient sexual health education when they arrive in Australia. They were concerned that some students may become more sexually active in Australia, and may not have adequate access to health services and information. All participants felt it was necessary for international students to receive better sexual health education. International students are important to Australian universities, and it should be mandatory to ensure that culturally appropriate sex education is made available to this group.

    Reciprocal and homologous mating experiments between Malaysian Aedes aegypti and Aedes albopictus mosquitoes were conducted in the laboratory. Two methods were employed, namely an artificial mating technique and a natural cage mating technique. The study demonstrated there exists a strong reproductive isolation between Ae. aegypti and Ae. albopictus. Insemination occurred in cross-mating experiments between Ae. aegypti females and Ae. albopictus males and also between Ae. albopictus females and Ae. aegypti males. Cross mating between Ae. aegypti females and Ae. albopictus males produced more eggs than that between Ae. albopictus females and Ae. aegypti males with both artificial mating and natural cage mating techniques. The matings did not result in the production of viable eggs by the females. No embryonation of these eggs was observed when the eggs were bleached. With homologous mating Aedes aegypti produced significantly greater numbers of eggs compared to Aedes albopictus mosquitoes, and all the eggs hatched successfully.

    Condom-murder is term used to describe a homicide where a person has been killed due to his recreational sexual behaviour and the killing has strong links with the recovered condom/contraceptive material on the scene or was in personal possession of victim. It can provide immediate clue about perpetrator. We present six cases of a similar nature. Four males and two females had condoms in their vicinity at crime scene. All incidents occurred at different timings and different places but there was striking similarity in method of killing. In four cases hands were tied on the back in three cases; similarly legs were also tied in three cases. In three cases strong electric cords were used. The presence of condoms give clue for investigation, possibility of DNA identification, about type of sexual behaviour as recreational and commercial method in these cases.

    The mating behaviors of the proboscis monkey were observed in a riverine forest along a tributary of the Kinabatangan River, Sabah, Malaysia, for a period of 30 months. Solicitation for copulation was initiated frequently by males and occasionally by females. Most copulations involved only one mount; however, some multiple-mount copulations were observed and a maximum of six mounts per copulation were recorded. The mean duration of mounts was about 27 sec. Nonsexual mounts (female-female, female-juvenile/infant, juvenile-juvenile, and juvenile-infant) were also observed. Female-female mounts occurred shortly after failed solicitations toward males were observed. Harassment by juveniles and/or infants was observed during copulation; however, these harassments apparently did not interfere with copulation. Sexual swelling was evident in 77.4% of copulating females, with copulating subadult females showing the most distinct swelling.

    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.

    BACKGROUND: Many groups of land snails show great interspecific diversity in shell ornamentation, which may include spines on the shell and flanges on the aperture. Such structures have been explained as camouflage or defence, but the possibility that they might be under sexual selection has not previously been explored.

    PRESENTATION OF THE HYPOTHESIS: The hypothesis that is presented consists of two parts. First, that shell ornamentation is the result of sexual selection. Second, that such sexual selection has caused the divergence in shell shape in different species.

    TESTING THE HYPOTHESIS: The first part of the hypothesis may be tested by searching for sexual dimorphism in shell ornamentation in gonochoristic snails, by searching for increased variance in shell ornamentation relative to other shell traits, and by mate choice experiments using individuals with experimentally enhanced ornamentation. The second part of the hypothesis may be tested by comparing sister groups and correlating shell diversity with degree of polygamy.

    IMPLICATIONS OF THE HYPOTHESIS: If the hypothesis were true, it would provide an explanation for the many cases of allopatric evolutionary radiation in snails, where shell diversity cannot be related to any niche differentiation or environmental differences.

    Malayan tapirs are listed as endangered and are bred in captivity under governmental management. The success of captive breeding programs varies and the underlying causes are unclear. Here, we investigate how tapir reproduction is affected by previous breeding experience, enclosure type/size and visitor numbers so that appropriate steps can be taken to achieve self-sustaining captive populations. Data on social and reproductive behaviors were collected from six tapirs (three males, three females), from different breeding centers in Peninsular Malaysia for 18 weeks. Results revealed that social and reproductive behavior of both sexes was significantly influenced by social and environmental conditions. Larger enclosure size tended to increase social and reproductive behaviors, whereas high number of visitors reduced initial interaction between males and females. No specific breeding month was confirmed; however, reproductive behaviors were highest in April. Overall, this study contributes to a better understanding of the relationships between social and reproductive behaviors, and captive environments on Malayan tapirs. In future, frequency of sexual interactions should be monitored regularly to identify animals exhibiting below-average frequency and who might, therefore, be prone to reproductive difficulties.

    Mating behavior between Aedes aegypti and Ae. albopictus, established colony strains were examined under laboratory conditions (30-cm(3) screened cages) for 5 consecutive days. The effect of selected male densities (30, 20, 10) and female density (20) on the number of swarming, mating pairs, eggs produced, and inseminated females were evaluated. Male densities significantly increased swarming behavior, mating pairs, and egg production of heterospecific females, but female insemination was reduced. Aedes aegypti males mate more readily with heterospecific females than do Ae. albopictus males. The current study suggests that Ae. aegypti males were not species-specific in mating, and if released into the field as practiced in genetically modified mosquito techniques, they may mate with both Ae. aegypti and Ae. albopictus females, hence reducing populations of both species by producing infertile eggs.

    The effect of sexual selection on species persistence remains unclear. The cost of bearing ornaments or armaments might increase extinction risk, but sexual selection can also enhance the spread of beneficial alleles and increase the removal of deleterious alleles, potentially reducing extinction risk. Here we investigate the effect of sexual selection on species persistence in a community of 34 species of dung beetles across a gradient of environmental disturbance ranging from old growth forest to oil palm plantation. Horns are sexually selected traits used in contests between males, and we find that both horn presence and relative size are strongly positively associated with species persistence and abundance in altered habitats. Testes mass, an indicator of post-copulatory selection, is, however, negatively linked with the abundance of species within the most disturbed habitats. This study represents the first evidence from a field system of a population-level benefit from pre-copulatory sexual selection.

    The aim of this study was to explore how people's sexual history affects their attractiveness. Using an Internet survey, 188 participants rated their willingness to engage in a relationship with a hypothetical individual with a specified number of past sexual partners, ranging from 0 to 60+. The effect of past partner number was very large. Average willingness ratings initially rose as past partner number rose, but then fell dramatically. For short-term relationships, men were more willing than women to get involved (although the difference was not large). For long-term relationships, in contrast, there was virtually no sex difference. Thus, contrary to the idea that male promiscuity is tolerated but female promiscuity is not, both sexes expressed equal reluctance to get involved with someone with an overly extensive sexual history. Finally, participants with an unrestricted sociosexual orientation (high SO participants) were more tolerant than low SO participants of prospective mates with higher numbers of past sexual partners but were also less tolerant of prospective mates with low numbers of past sexual partners.

    A young man presented with high libido for 3 years, associated with preoccupation with sexual thoughts combined with his pursuit of pornographic materials. He had strong psychological cravings for and had spent large amount of money on sex, resulting in a dispute with his family. There were no mood or psychotic symptoms. Medical history revealed recent diagnosis of gonococcal urethritis. Cognitive assessment showed subtle deficiencies in reasoning and executive functions. There was occasional use of alcohol. Sexual addiction with comorbid mild intellectual disability was diagnosed, and pharmacological as well as psychological management were started.

    AIM: To identify the determinants of sexual intimacy among married older people in Malaysia.

    METHODS: A cross-sectional study was carried out among 1294 married Malaysian older couples who were randomly selected from all 14 states in Malaysia. The data were collected by trained enumerators using a set of validated questionnaires consisting of eight sections, namely sociodemographic characteristics, chronic diseases, perceived health status, life satisfaction, body mass index, disability status (World Health Organization Disability Assessment Schedule), social support (Lubben Social Network Scale) and sexual intimacy.

    RESULTS: Having good social support (AOR 0.57, 95% CI 0.45-0.74) from family and friends were protective determinants against poor sexual intimacy in later life. Meanwhile, those who were aged 70-79 years (AOR 1.81, 95% CI 1.35-2.42), aged >80 years (AOR 35.49, 95% CI 4.80-262.18), women (AOR 1.47, 95% CI 1.13-1.90), non-Malay (AOR 1.93, 95% CI 1.50-2.48), received only informal education (AOR 1.81, 95% CI 1.35-2.42), had gastritis (AOR 2.62, 95% CI 1.58-4.34), had a stroke (AOR 3.83, 95% CI 1.04-14.12), perceived their current health status was satisfactory (AOR 1.52, 95% CI 1.15-2.00) and disabled based on the World Health Organization Disability Assessment Schedule (AOR 3.14, 95% CI 1.34-7.36) were at risk of poor sexual intimacy.

    CONCLUSIONS: The majority of older Malaysian couples were having poor sexual intimacy despite being still married and sleeping with their partners, reflecting the presence of underlying barriers towards sexual intimacy in later life among older Malaysians.

    Sexual dysfunction has been extensively studied in methadone maintenance treatment (MMT) patients. However, little data is available regarding sexual inactivity in the MMT patient population. The objectives of this study were to determine the prevalence and putative risk factors for sexual inactivity in the MMT patient population. This cross-sectional study involved 25-71 year old MMT patients recruited from six methadone clinics. Two hundred and seventy-one patients were interviewed for demographic characteristics, comorbidities, concurrent medications used, and sexual activity. The prevalence of sexual inactivity in the MMT population was found to be 47.6%. Increasing age (p < 0.01) and being single/divorced (p < 0.01) were significantly associated with sexual inactivity. In subgroup analysis, increasing age was significantly associated with sexual inactivity in both single/divorced (p < 0.05) and married (p < 0.05) subgroups, while unemployment (p < 0.05) was only significantly associated with sexual inactivity in the earlier subgroup. Our results suggest that sexual inactivity is common in the MMT patient population. The putative risk factors are related to biological and sociocultural factors. Having specific comorbidities or being on certain medications were not correlated with sexual inactivity in the MMT population. Routine assessment of sexual problems is essential, and proper management should be performed for MMT patients.

    The effects of Eurycoma longifolia JACK were studied on the orientation activities of sexually experienced male rats towards receptive females (mounting, licking, anogenital sniffing), environment (exploration, raring, climbing), themselves (genital grooming, non-genital grooming) and mobility (unrestricted, restricted) after dosing them with 200, 400 and 800 mg/kg body weight twice daily for 10 d prior to the test. The results showed that E. longifolia JACK modified the orientation activities of the treated male rats in that they significantly displayed more frequent and vigorous mounting, licking and anogenital sniffing towards the receptive females, and it further intensified self orientation as indicated by the increased grooming of the genitals compared to the controls (p<0.05). In addition, rats treated with 800 mg/kg of methanol, water and butanol extracts of E. longifolia JACK continued to show confinement to a particular area of the cage (around the female), thus showing restriction in movement as compared to the controls (p<0.05). However, the treated males possessed a lack of interest in the external environment as indicated by a reduction in exploration, raring and climbing on the cage wall. Hence, the present study further supports the folk use of E. longifolia JACK as an aphrodisiac.

    The aim of this study is to provide evidence on the aphrodisiac property of Eurycoma longifolia Jack. An electric grid was used as an obstruction in the electrical copulation cage in order to determine how much an aversive stimulus the sexually naive male rat for both the treated with E. longifolia Jack and control groups were willing to overcome to reach the estrous receptive female in the goal cage. The intensity of the grid current was maintained at 0.12 mA and this was the intensity in which the male rats in the control group failed to crossover to reach the goal cage. Results showed that E. longifolia Jack continued to enhance and also maintain a high level of both the total number of successful crossovers, mountings, intromissions and ejaculations during the 9-12th week observation period. In conclusion, these results further enhanced and strengthened the aphrodisiac property of E. longifolia Jack.

    Exposure to endocrine-disrupting chemicals may adversely affect animals, particularly during development. Tris(1,3-dichloroisopropyl) phosphate (TDCIPP) is an organophosphate with anti-androgen function in vitro that is present in indoor dust at relatively high concentrations. In male rats, androgens are necessary for the development of reproductive organs, as well as the endocrine and central nervous systems. However, we currently do not know the exact effects of TDCIPP exposure through suckling on subsequent reproductive behavior in males. Here, we show that TDCIPP exposure (25-250 mg kg-1 via oral administration over 28 consecutive days post-birth) suppressed male sexual behavior and reduced testes size. These changes were dose-dependent and appeared first in adults rather than in juveniles. These results demonstrate that TDCIPP exposure led to normal body growth and appearance in juveniles, but disrupted the endocrine system and physiology in adults. Therefore, assays should be performed using adult animals to ensure accuracy, and to confirm the influence of chemical substances given during early mammalian life.

    INTRODUCTION: Sexual assault is a serious social problem. Due to its stigma, it is severely underreported with the survivors delay in seeking treatment. We aim to study the patterns, clinical characteristics, and time taken to manage sexual assault cases in our One Stop Crisis Centre (OSCC), and determine the factors associated with delayed presentation.

    MATERIALS AND METHODS: This was an observational case review study of all sexual assault cases from 2012-2017 at the OSCC of a suburban, tertiary hospital in Malaysia. A total of 304 cases were analysed.

    RESULTS: The median age of the survivors was 15 years old. Majority were females (n=291, 95.7%), single (n=290, 95.4%), students (n=235, 77.3%), and from low socio-economic class (n=230, 75.7%). Rape constitutes the majority (n=246, 80.6%) with 153 cases (62.1%) were statutory rape. The most common perpetrator was the victim's boyfriend (n=107, 35.2%) while only 60 cases (19.7%) involved strangers. Delayed presentations were more likely among victims who previously knew their perpetrators (AOR 2.53, 95% CI: 1.37 to 4.68, p<0.01). The median duration for management at OSCC was 6.48 hours.

    CONCLUSION: Majority of sexual assault survivors were females, teenagers, and from low socio-economic class. Rape, mainly statutory rape, made the majority of cases. Therefore, sexual and safety education targeting primary intervention should be started early. Multidisciplinary teams must work together to optimise the management of sexual assault.
