Sabah, located in Southeast Asia, hosts the highest number of non-Malaysian citizens (27.7%), predominantly the Indonesian and Filipino migrants in comparison to other states in Malaysia. Sabah has inadequate data on migrants' sexual and reproductive health and rights (SRHRs). Various migrant-related policies and laws are present, but they do not offer full protection and rights to legal migrants in terms of their SRHRs. The aim of the laws and policies appears to be controlling the migrants from having any negative impact on the locals, rather than protecting migrants' health and rights. This affected their rights to marriage, having children, increase their vulnerabilities to labour trafficking and sexual abuse and access to health-care services. Female migrant workers and undocumented migrants form the most vulnerable subgroups of migrants. This narrative review highlights the status of SRHRs of migrants in Sabah and the migrant-related Malaysian laws and policies affecting their SRHRs.

Providing sexual and reproductive health (SRH) services to migrant workers is key to fulfilling sustainable developmental goals. This study aims to explore key informants' views on the provision of SRH services for migrant women in Malaysia, exploring the provision of SRH education, contraception, abortion, antenatal and delivery, as well as the management of gender-based violence. In-depth interviews of 44 stakeholders were conducted from July 2018 to July 2019. Data were thematically analysed. Migrant workers that fall pregnant are unable to work legally and are subject to deportation. Despite this, we found that insufficient SRH information and contraceptive access are provided, as these are seen to encourage promiscuity. Pregnancy, rather than sexually transmitted infection prevention, is a core concern among migrant women, the latter of which is not adequately addressed by private providers. Abortions are often seen as the only option for pregnant migrants. Unsafe abortions occur which are linked to financial constraints and cultural disapproval, despite surgical abortions being legal in Malaysia. Pregnant migrants often delay care-seeking, and this may explain poor obstetric outcomes. Although health facilities for gender-based violence are available, non-citizen women face additional barriers in terms of discrimination and scrutiny by authorities. Migrant women face extremely limited options for SRH services in Malaysia and these should be expanded.

Midlife crisis perceptions, experiences, help-seeking, and needs among multi-ethnic malaysian women

Wong LP, Awang H, Jani R

Women Health, 2012;52(8):804-19.
PMID: 23127220 DOI: 10.1080/03630242.2012.729557

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.

MyJurnal

Methamphetamine production and abuse increased significantly in Malaysia. Lesbian, gay, bisexual and transgender (LGBT) populations have higher prevalence of substance abuse compared to general population. Their unmet needs pose greater challenges in managing their substance related disorders. This paper described the agony of a Malaysian lesbian with gender identity disorder who abused substances and developed amphetamine-induced psychosis. Her sexual identity issue was explored in managing her substance related disorders to improve her outcome.

Metformin mitigates impaired testicular lactate transport/utilisation and improves sexual behaviour in streptozotocin-induced diabetic rats

Nna VU, Abu Bakar AB, Ahmad A, Mohamed M

Arch Physiol Biochem, 2021 Feb;127(1):51-60.
PMID: 31072137 DOI: 10.1080/13813455.2019.1610778

CONTEXT: Lactate is the preferred energy substrate for developing testicular germ cells. Diabetes is associated with impaired testicular lactate transport/utilisation, and poor sexual behaviour.
OBJECTIVE: To examine the effects of metformin on parameters involved in testicular lactate production, transport/utilisation, and sexual behaviour in diabetic state.
METHODS: Male Sprague-Dawley rats were assigned into normal control (NC), diabetic control (DC), and metformin-treated diabetic group (n = 6/group). Metformin (300 mg/kg b.w./day) was administrated orally for 4 weeks.
RESULTS: Intra-testicular glucose and lactate levels, and lactate dehydrogenase (LDH) activity increased, while the mRNA transcript levels of genes responsible for testicular glucose and lactate transport/utilisation (glucose transporter 3, monocarboxylate transporter 4 (MCT4), MCT2, and LDH type C) decreased in DC group. Furthermore, penile nitric oxide increased, while cyclic guanosine monophosphate decreased, with impaired sexual behaviour in DC group. Treatment with metformin improved these parameters.
CONCLUSIONS: Metformin increases testicular lactate transport/utilisation and improves sexual behaviour in diabetic state.

Menopausal women's experiences of husband's support: A negative view

Hassan II, Nik Hussain NH, Sulaiman Z, Abdul Kadir A, Mat Nor MZ

Enferm Clin, 2020 03;30 Suppl 2:190-193.
PMID: 32204142 DOI: 10.1016/j.enfcli.2019.07.075

OBJECTIVE: This study explores how menopausal women perceived supports provided by their husbands.
METHODOLOGY: Total of 13 menopausal women recruited using a combination of purposive and snowball techniques from two sources, tertiary hospital and local communities in the state of Kelantan, Malaysia. The in-depth semi-structured interview guided was used to explore how they perceived supports provided by their husbands. The data were then analysed using a thematic analysis.
RESULTS: Five (5) themes have emerged which comprises of emotional, instrumental, appraisal, guidance, and sexual supports. One of which was a new theme (sexual intimacy support) that had not been existed previously in other literature reviews.
CONCLUSION: Majority of menopausal women perceived the supports provided by their husband were negative, rather than positive supports that they had hoped. These findings suggest that an education program tool for husbands as a support person is much needed to ensure women walk through the menopause phase in a more meaningful life.

Fulltext Mechanisms of sex determination and transmission ratio distortion in Aedes aegypti

Hoang KP, Teo TM, Ho TX, Le VS

Parasit Vectors, 2016 Jan 28;9:49.
PMID: 26818000 DOI: 10.1186/s13071-016-1331-x

BACKGROUND: More effective mosquito control strategies are urgently required due to the increasing prevalence of insecticide resistance. The sterile insect technique (SIT) and the release of insects carrying a dominant lethal allele (RIDL) are two proposed methods for environmentally-friendly, species-targeted population control. These methods may be more suitable for developing countries if producers reduce the cost of rearing insects. The cost of control programs could be reduced by producing all-male mosquito populations to circumvent the isolation of females before release without reducing male mating competitiveness caused by transgenes.
RESULTS: An RNAi construct targeting the RNA recognition motif of the Aedes aegypti transformer-2 (tra-2) gene does not trigger female-to-male sex conversion as commonly observed among dipterous insects. Instead, homozygous insects show greater mortality among m-chromosome-bearing sperm and mm zygotes, yielding up to 100% males in the subsequent generations. The performance of transgenic males was not significantly different to wild-type males in narrow-cage competitive mating experiments.
CONCLUSION: Our data provide preliminary evidence that the knockdown of Ae. aegypti tra-2 gene expression causes segregation distortion acting at the level of gametic function, which is reinforced by sex-specific zygotic lethality. This finding could promote the development of new synthetic sex distorter systems for the production of genetic sexing mosquito strains.

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.

Mating compatibility and competitiveness of transgenic and wild type Aedes aegypti (L.) under contained semi-field conditions

Lee HL, Vasan S, Ahmad NW, Idris I, Hanum N, Selvi S, et al.

Transgenic Res, 2013 Feb;22(1):47-57.
PMID: 22700207 DOI: 10.1007/s11248-012-9625-z

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.

Mating behaviors of the proboscis monkey (Nasalis larvatus)

Murai T

Am J Primatol, 2006 Aug;68(8):832-7.
PMID: 16847976 DOI: 10.1002/ajp.20266

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.

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 Male-lure type, lure dosage, and fly age at feeding all influence male mating success in Jarvis' fruit fly

Wee SL, Clarke AR

Sci Rep, 2020 09 14;10(1):15004.
PMID: 32929156 DOI: 10.1038/s41598-020-72209-x

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.

Fulltext Male sexual dysfunction in Asia

Ho CC, Singam P, Hong GE, Zainuddin ZM

Asian J Androl, 2011 Jul;13(4):537-42.
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.

Male sex pheromonal components derived from methyl eugenol in the hemolymph of the fruit fly Bactrocera papayae

Hee AK, Tan KH

J Chem Ecol, 2004 Nov;30(11):2127-38.
PMID: 15672660 DOI: 10.1023/B:JOEC.0000048778.02561.70

Pharmacophagy of methyl eugenol (ME)--a highly potent male attractant, by Bactrocera papayae results in the hydroxylation of ME to sex pheromonal components, 2-ally-4,5-dimethoxyphenol (DMP) and (E)-coniferyl alcohol (CF). These compounds, which are also male attractants, are then sequestered and stored in the rectal gland prior to their release during courtship at dusk. Chemical analyses of the digestive tract (excluding the crop and rectal gland) showed the absence of the sex pheromonal components and their precursor, ME. However, B. papayae males were attracted to and fed on the ME-fed male hemolymph extracts but not on hemolymph extracts of ME-deprived males. After thin layer chromatography in a hexane:ethyl acetate solvent system, flies were attracted to and fed on the original point on the TLC plate where the hemolymph extract had been spotted, suggesting that the pheromone components were bound in polar complexes. Chemical analyses of the ME-fed male hemolymph and crop extracts revealed the presence of the sex pheromonal components. The presence of the ME-derived pheromonal components and the absence of ME in the hemolymph suggest that the hemolymph is involved in the transportation of sex pheromonal components from the crop to the rectal gland.

Male circumcision and penis enhancement in Southeast Asia: matters of pain and pleasure

Hull TH, Budiharsana M

Reprod Health Matters, 2001 Nov;9(18):60-7.
PMID: 11765401

This paper reviews some uniquely male sexual health concerns in Southeast Asia, with particular attention to Indonesia. These include various forms of male circumcision, different types of 'penis enhancement' carried out across the region and the use of dry sex by women. These practices appear to be motivated by specific notions of sexual pleasure, based on indigenous gender constructs. Although they may or may not pose a serious public health problem, as markers of misguided or exploitative gender relations they do reveal important aspects of social psychology related to sexuality and sexual health. Male circumcision provides an ideal opportunity to consider male reproductive health needs and risks in Indonesia, Malaysia and the Philippines. Practices that involve cutting the male genitals need to be addressed in ways that stress the importance of sexual relationships based on mutual respect and open communication. Penis implants and inserts and other penis augmentation devices, as well as dry sex practices, are potentially dangerous to both men and women, and of questionable value in bringing pleasure to either, and should be discouraged.

Fulltext Malaysian youth sexuality: issues and challenges

Low, W.Y.

JUMMEC, 2009;12(1):3-14.
MyJurnal

Youth sexuality is a great concern for many. Sexual health issues facing our youths are: premarital sexual intercourse, sexually transmitted diseases, unwanted and unsafe pregnancies and abortions, sexual diversity, HIV/AIDS, and cybersex. Various factors lead to risky sexual and reproductive health behavior, particularly among those unmarried youths: lack of sexual and reproductive health information and skills in negotiating sexual relationships and the inaccessibility of youth-friendly sexual and reproductive health services. Growing peer pressure of pre-marital sex plays a major role in sexual and reproductive health related decision-making among youths. Another factor is the issue of sexuality education which is still considered a sensitive topic and thus impinging on its implementation, due to cultural and religious constraints. Misunderstanding and a lack of information on sexual diversity have caused a concern for many, as there is a tendency for judgments, stereotypes, discriminations and prejudices towards homosexuality in the society. Online sexual activities or cybersex have become the next sexual revolution. Negative consequences are shown for those hooked on cybersex. Healthy youths are fundamental to the prevention initiatives. Promoting the sexual and reproductive needs and rights of our youths is warranted.

Fulltext Malaysian propolis and metformin mitigate subfertility in streptozotocin-induced diabetic male rats by targeting steroidogenesis, testicular lactate transport, spermatogenesis and mating behaviour

Nna VU, Bakar ABA, Ahmad A, Umar UZ, Suleiman JB, Zakaria Z, et al.

Andrology, 2020 05;8(3):731-746.
PMID: 31816190 DOI: 10.1111/andr.12739

BACKGROUND: Diabetes mellitus is one of the risk factors for male subfertility/infertility. Malaysian propolis is reported to decrease hyperglycaemia in diabetic state.
OBJECTIVES: The present study investigated the protective effect of Malaysian propolis on diabetes-induced subfertility/infertility. Additionally, its combined beneficial effects with metformin were investigated.
MATERIALS AND METHODS: Forty adult male Sprague Dawley rats were randomly assigned into five groups, namely normal control, diabetic control, diabetic + Malaysian propolis (300 mg/k.g. b.w.), diabetic + metformin (300 mg/kg b.w.) and diabetic + Malaysian propolis + metformin. Diabetes was induced using a single intraperitoneal injection of streptozotocin (60 mg/kg b.w.) and treatment lasted for 4 weeks. During the 4th week, mating behavioural experiments were performed using sexually receptive female rats. Thereafter, fertility parameters were assessed in the female rats.
RESULTS: Malaysian propolis increased serum and intratesticular free testosterone levels, up-regulated the mRNA levels of AR and luteinizing hormone receptor, up-regulated the mRNA and protein levels of StAR, CYP11A1, CYP17A1, 3β-HSD and 17β-HSD in the testes of diabetic rats. Furthermore, Malaysian propolis up-regulated testicular MCT2, MCT4 and lactate dehydrogenase type C mRNA levels, in addition to improving sperm parameters (count, motility, viability and normal morphology) and decreasing sperm nDNA fragmentation in diabetic rats. Malaysian propolis improved mating behaviour by increasing penile guanosine monophosphate levels. Malaysian propolis also improved fertility outcome as seen with decreases in pre- and post-implantation losses, increases in gravid uterine weight, litter size per dam and foetal weight. Malaysian propolis's effects were comparable to metformin. However, their combination yielded better results relative to the monotherapeutic interventions.
CONCLUSION: Malaysian propolis improves fertility potential in diabetic state by targeting steroidogenesis, testicular lactate metabolism, spermatogenesis and mating behaviour, with better effects when co-administered with metformin. Therefore, Malaysian propolis shows a promising complementary effect with metformin in mitigating Diabetes mellitus-induced subfertility/infertility.
