    13 patients with the amenorrhoea-galactorrhoea syndrome who conceived during treatment with bromocriptine were reported. Mean period of amenorrhoea was 3.0 years. In ten patients galactorrhoea was noted for a mean period of 4.2 years while in three it was discovered during examination. Seven patients presented with primary infertility. Menses returned in all cases after a mean duration of 2 months of treatment with bromocriptine at an average dose of 5. 86 mg daily. Mean serum prolactin was 4344 mUll (range 750 mU/l to 23,000 mU/l) before treatment and this declined to 186 mU/l with treatment. Seven patients became pregnant 5 to 25 months of treatment while six conceived after first menses. 21 pregnancies resulted from the thirteen patients. There was one spontaneous abortion and one premature delivery in which the baby died. Of the 16 live- births, there were twelve girls and four boys and their mean birth-weight was 2932 g. All were normal at birth and during subsequent developments except one with congenital dislocation of hip. It is concluded that bromocriptine is effective in restoring menstrual cycles and fertility by lowering serum prolactin in patients with the amenorrhoea-galactorrhoea syndrome. Bromocriptine may be safe for use during pregnancy, but it is suggested that the medication should be stopped immediately after conception unless tumour growth is apparent.

    Tuberculosis of the genital tract was diagnosed in only 12 patients during the 17 year period from March 1968 to February 1985 at the University Hospital, Kuala Lumpur, which serves as a major referral centre in Malaysia. The incidence was 0.31 per 1000 gynaecological admissions and the peak age incidence was in the age group 26 to 35 years. The surgical management was mainly conservative as infertility was the most frequent mode of presentation (50%). Evidence of previous pulmonary tuberculosis was present in only five cases. Adnexal adhesions were the commonest pelvic finding; the fallopian tubes and endometrium were affected with equal frequency. Positive cultures for Mycobacterium tuberculosis were obtained in only five of the 12 patients. All patients received combination anti-tuberculosis drugs with satisfactory response.

    Aims:
    To understand the molecular pathways involved in oxidative stress (OS)-mediated sperm dysfunction against a hypoxic and hyperthermic microenvironment backdrop of varicocele through a proteomic approach.
    Results:
    Protein selection (261) based on their role in redox homeostasis and/or oxidative/hyperthermic/hypoxic stress response from the sperm proteome data set of unilateral varicocele (UV) in comparison with fertile control displayed 85 to be differentially expressed. Upregulation of cellular oxidant detoxification and glutathione and reduced nicotinamide adenine dinucleotide (NADH) metabolism accompanied with downregulation of protein folding, energy metabolism, and heat stress responses were observed in the UV group. Ingenuity pathway analysis (IPA) predicted suppression of oxidative phosphorylation (OXPHOS) (validated by Western blotting [WB]) along with augmentation in OS and mitochondrial dysfunction in UV. The top affected networks indicated by IPA involved heat shock proteins (HSPs: HSPA2 and HSP90B1). Their expression profile was corroborated by immunocytochemistry and WB. Hypoxia-inducible factor 1A as an upstream regulator of HSPs was predicted by MetaCore. Occurrence of reductive stress in UV spermatozoa was corroborated by thiol redox status.
    Innovation:
    This is the first evidence of a novel pathway showing aberrant redox homeostasis against chronic hypoxic insult in varicocele leading to sperm dysfunction.
    Conclusions:
    Upregulation of antioxidant system and dysfunctional OXPHOS would have shifted the redox balance of biological redox couples (GSH/GSSG, NAD+/NADH, and NADP+/NADPH) to a more reducing state leading to reductive stress. Chronic reductive stress-induced OS may be involved in sperm dysfunction in infertile men with UV, where the role of HSPs cannot be ignored. Intervention with antioxidant therapy warrants proper prior investigation.

    The worldwide declining trend in male fertility has been a steady concern since the past few decades. Male infertility reportedly accounts for half of the overall infertility cases in the world. Despite the evidences of reduced fertility rates in Malaysia in the recent years, there is lack of interventions regarding the reproductive parameters in Malaysian men. Complexity in determining the underlying causatives in most of the male subfertility and infertility cases limits the scope of management. The sociodemographic impacts upon overall health as well as on reproductive health of men are undeniable. The present study has analysed the data collected from patients' records in the Fertility Clinic, International Islamic University Malaysia (IIUM), from the January 2009 until December 2018. A total of 300 male patients were included in the study and were categorised according to their seminal fluid analysis (SFA) records. The sociodemographic characteristics for each subject were analysed. The results presented significant correlations among essential sociodemographic factors, such as educational attainment, marital duration as well as the age of wife, with the levels of semen abnormalities in the subjects. The study thereby unleashes scope for further investigations focusing upon the demographic factors for better insights to ameliorate male reproductive health in the Malaysian population.

    A parallel group superiority prospective randomised controlled trial was devised to compare the culture characteristics of human pre-implantation stage embryos during uninterrupted culture in a time lapse incubator (TLI) versus the conventional model of interrupted culture in a standard incubator (SI) under low oxygen tension using a single step medium. 221 patients aged 35-and-under, 124 patients aged between 36 and 39 and 86 patients aged 40-and-over years were randomised and cultured either in a SI or in a TLI. Patients in the three age groups were distributed between the TLI and SI in a 1:1 ratio. The development of embryos on days 2, 3 and 5, and the clinical pregnancy and implantation rates were recorded. The fertilisation rate, development of day 2 and clinical pregnancy rates were similar in both treatments but the 8-cell development rate in all age groups combined (p = 0.016), blastocyst development rate (p = 0.0022) and the implantation rate (p = 0.0022) was significantly higher for the uninterrupted culture. These findings demonstrated significant differences between the two incubation groups. It also indicated less efficacious embryonic development with age in both treatments which appeared more pronounced in the conventional incubator. In conclusion uninterrupted culture is superior compared to the interrupted incubation culture system.

    OBJECTIVE: To determine if lipid peroxides were raised in the pelvic peritoneal fluid of patients with endometriosis.

    DESIGN: Control study involving patients with and without endometriosis.

    METHODS: The lipid peroxide (malondialdehyde) levels in the pelvic PF of 12 patients with moderate-to severe endometriosis, 15 patients with minimal-mild endometriosis and 13 patients with normal pelvises were compared.

    RESULTS: The level of lipid peroxides were not affected by the presence nor the severity of endometriosis.

    CONCLUSION: Accelerated lipid peroxidation does not appear to play a role in the causal relationship between endometriosis and infertility.

    Zinc (Zn), the second-most necessary trace element, is abundant in the human body. The human body lacks the capacity to store Zn; hence, the dietary intake of Zn is essential for various functions and metabolism. The uptake of Zn during its transport through the body is important for proper development of the three major accessory sex glands: the testis, epididymis, and prostate. It plays key roles in the initial stages of germ cell development and spermatogenesis, sperm cell development and maturation, ejaculation, liquefaction, the binding of spermatozoa and prostasomes, capacitation, and fertilization. The prostate releases more Zn into the seminal plasma during ejaculation, and it plays a significant role in sperm release and motility. During the maternal, labor, perinatal, and neonatal periods, the part of Zn is vital. The average dietary intake of Zn is in the range of 8-12 mg/day in developing countries during the maternal period. Globally, the dietary intake of Zn varies for pregnant and lactating mothers, but the average Zn intake is in the range of 9.6-11.2 mg/day. The absence of Zn and the consequences of this have been discussed using critical evidence. The events and functions of Zn related to successful fertilization have been summarized in detail. Briefly, our current review emphasizes the role of Zn at each stage of human reproduction, from the spermatogenesis process to childbirth. The role of Zn and its supplementation in in vitro fertilization (IVF) opens opportunities for future studies on reproductive biology.

    Reports of the increasing incidence of male infertility paired with decreasing semen quality have triggered studies on the effects of lifestyle and environmental factors on the male reproductive potential. There are numerous exogenous and endogenous factors that are able to induce excessive production of reactive oxygen species (ROS) beyond that of cellular antioxidant capacity, thus causing oxidative stress. In turn, oxidative stress negatively affects male reproductive functions and may induce infertility either directly or indirectly by affecting the hypothalamus-pituitary-gonadal (HPG) axis and/or disrupting its crosstalk with other hormonal axes. This review discusses the important exogenous and endogenous factors leading to the generation of ROS in different parts of the male reproductive tract. It also highlights the negative impact of oxidative stress on the regulation and cross-talk between the reproductive hormones. It further describes the mechanism of ROS-induced derangement of male reproductive hormonal profiles that could ultimately lead to male infertility. An understanding of the disruptive effects of ROS on male reproductive hormones would encourage further investigations directed towards the prevention of ROS-mediated hormonal imbalances, which in turn could help in the management of male infertility.

    The objective of this study was to determine the seroprevalence of cytomegalovirus (CMV) infections through antenatal screening data and the association of this virus with obstetric complications. Serum samples from 125 apparently healthy pregnant women sent for antenatal screening from various hospitals in Malaysia between January 2007 and December 2008, were examined for CMV specific IgM and IgG antibodies using an enzyme-linked immunosorbent assay method. Of the 125 pregnant women tested, anti-CMV IgG antibody was found in 105 (84%) of the cases and anti-CMV IgM in 9 cases (7.2%). Both CMV IgM and IgG were also found in another 37 women whose serum samples were sent for investigation of various obstetric complications: 17 cases of spontaneous abortions, 15 cases of fetal anomalies detected during ultrasound examination, 1 case of incomplete abortion, 3 cases with premature delivery of infant with congenital anomalies and 1 case of infertility. Our preliminary data which only represented a small study group has shown the prevalence of CMV infection among the local population and the association of CMV in obstetric complications.

    A prospective randomised study was done to assess the effect of supplemental oestradiol in addition to progesterone on the luteal steroid profiles and pregnancy outcome in stimulated cycles with and without pituitary down regulation. Women undergoing stimulated cycle IVF with GnRH-a and FSH (Group A, n = 63) or stimulated intrauterine insemination using CC and FSH (Group B, n = 55) were studied. These subjects were randomly allocated to receive either 400 mg daily of vaginally administrated Cyclogest (progesterone) alone or in combination with 2 mg daily of oral Oestradiol Valerate (E2V) during the luteal phase. Significant lower concentrations of plasma progesterone were observed in those subjects supplemented with both E2V and progesterone compared to those in whom progesterone only was given during the luteal phase (P < 0.05). Exogenous E2V had a minimal impact on plasma oestradiol concentrations and did not disguise the characterised mid luteal decline in oestradiol secretion. The suppressive effect of E2V on plasma progesterone was lost if implantation occurred normally because any small change in steroid concentrations was reversed by the rapidly increasing concentrations of HCG. Similar pregnancy rates were observed among subjects supplemented with or without oestradiol. The addition of oestradiol to the luteal supplement suppresses endogenous corpus luteum progesterone secretion irrespective of the type of assisted conception cycle and that its use is unlikely to be beneficial to the process of implantation.

    Destruction of spermatogonial stem cells (SSCs) along the chemotherapy and radiotherapy is one of the side effects of cancer treatments that lead to infertility. In vitro propagation of hSSCs is necessary to obtain an adequate number of cells for successful transplantation. In this study, hSSCs were isolated from testis biopsies of the patients with maturation arrest and proliferated in DMEM in the presence of LIF and bFGF for 5 weeks. The various types of human spermatogonia were identified in culture system and compared with testis tissue using morphological criteria at the ultrastructural level. The results showed that although many various types of spermatogonia were identified, but no remarkable difference was observed between spermatogonial cells in culture system and testis tissue. Electron and light microscopic studies of hSSC colonies did not show differentiated SSCs in the culture system. The results also showed that probably the suitable time for transplanting of SSCs in recipient testis is 2-3 weeks after culture. Because apoptosis which may affect the development of germ cells has not started in colony cells at this time and the population of apoptotic cells are low.

    The cervical microbiota constitutes an important protective barrier against the invasion of pathogenic microorganisms. A disruption of microbiota within the cervical milieu has been suggested to be a driving factor of sexually transmitted infections. These include Chlamydia trachomatis which frequently causes serious reproductive sequelae such as infertility in women. In this study, we profiled the cervical microbial composition of a population of 70 reproductive-age Malaysian women; among which 40 (57.1%) were diagnosed with genital C. trachomatis infection, and 30 (42.8%) without C. trachomatis infection. Our findings showed a distinct compositional difference between the cervical microbiota of C. trachomatis-infected subjects and subjects without C. trachomatis infection. Specifically, significant elevations of mostly strict and facultative anaerobes such as Streptococcus, Megasphaera, Prevotella, and Veillonella in the cervical microbiota of C. trachomatis-positive women were detected. The results from the current study highlights an interaction of C. trachomatis with the environmental microbiome in the endocervical region.

    This seven-year retrospective study analysed the live birth rate (LBR) for women undergoing IVF treatment with various antral follicle counts (AFC). The LBR decreased with lower AFC ratings, and in 290 treatment cycles for women in the poorest AFC category, ≤4 follicles (group E), the LBR was the lowest at 10.7%. The pregnancy loss rate (PLR) significantly increased with poorer AFC categories, from 21.8% in AFC group A (≥20 follicles), to 54.4% in AFC group E (p<0.0001). This trend was repeated with advancing age, from 21.6% for younger women (<35years), to 32.9, 48.5 and 100% for ages 35-39, 40-44 and ≥45 years, respectively (p<0.0001). However, LBR within the specific AFC group E cohort was also age-dependent and decreased significantly from 30.0% for <35 years old, to 13.3, 3.9 and 0% for patients aged 35-39, 40-44 and ≥45 years, respectively. Most, importantly, LBR rates within these age groups were not dependent on the number of IVF attempts (1st, 2nd, 3rd or ≥4 cycles), which indicated that cycle number should not be the primary deciding factor for cessation of IVF treatment in responding women <45years old.

    Testicular veins are known to show many variations in their origin, course and termination. Some of their variations can lead to male sterility. We report a unique variation of right testicular vein here. Pampiniform plexus reduced to three testicular veins (medial, middle and lateral) at the deep inguinal ring on the right side. The medial vein terminated into the right renal vein, the middle vein terminated into the inferior vena cava above the level of right renal vein (close to the suprarenal gland) and the lateral vein terminated partly into the veins in the capsules of the kidney and partly into the veins under the diaphragm. The medial and middle testicular veins were connected through an oblique communicating vein. The middle and lateral testicular veins were also connected to each other through another oblique communicating vein. Knowledge of this case could be useful to radiologists, nephrologists and surgeons in general.

    Introduction: Implantation is one of critical step in human reproductive processes. There are many factors that affect successful implantation. Good quality embryo or blastocyst is a prerequisite to successful implantation together with a receptive endometrium. The purpose of this study is to describe the patient clinical profile and to investigate the factors of interest association with implantation status. Methods: This is a cross sectional study involving patients planned for in vitro fertilization (IVF) treatment in the hospital infertility clinic. All demographic data and clinical profile data of the patient in each visit was recorded. Among the data taken were, physical examination data, patient history, causes of infertility, hormonal investigation and outcome at the end of treatment (presence of fetal heart). Successful implantation is indicated by presence of fetal heart. Results: A total of 246 patients record were collected. Mean age of the patient was 34.2 (SD = 4.12) years old. Mean BMI was 24.5 kg/m2 (SD=4.70). Mean of infertility years among the patients was 5.9 years (SD= 3.40). Most cause of infertility was tubal issues 87 cases (35.4%). The prevalence of successful implantation was 12.8% ((95% CI 7.8%, 17.8%). None of the factors of interest (age, BMI, infertility duration, progesterone at baseline, progesterone at trigger day) were found associated with successful implantation. Out of 224 patients, 53 (21.5%) were having elevated progesterone level at trigger day. However, in this study, there is no conclusive evidence that level of progesterone is associated with successful implantation. Conclusion: The successful implantation in our setting is approximately 1/10 of IVF treatment. Implantation involved a complex mechanism, thus there is wide variety of etiologies to predict for successful implantation. Thus, further study on wide comprehensive of risk factors is warranted.

    One of the goals of medicine is to improve well-being, in line with the principle of beneficence (do no harm). Likewise, scientists claim that the goal of human embryonic stem cell (hESC) research is to find treatments for diseases. In hESC research, stem cells are harvested from a 5-day-old embryo. Surplus embryos from infertility treatments or embryos created for the sole purpose of harvesting stem cells are used in the research, and in the process the embryos get destroyed. The use of human embryos for research purpose raises ethical concern. In this context, the religious leaders play the role to be the moral compass and "reality check" to engage with the public. In Malaysia, the Ministry of Health has outlined the Guidelines for Stem Cell Research and Therapy, reflecting on Islamic principles. Since there has not been much focus on the viewpoints of other faiths in Malaysia, this study attempts to (i) explore the ethical guiding principles deliberated by religious leaders from the Buddhist, Hindu and Catholic traditions and (ii) identify if there is a common ground between the mainstream religious views and principles of medical ethics, in relation to hESC research. Eleven religious leaders representing the Buddhist, Hindu and Catholic traditions were interviewed. Interestingly, though reasoning of religious leaders came from different angles, their underlying concerns revolve around the values of "do no harm" and "intention to save lives". These values are also the key principles in medical ethics. The findings are applied to answer the question as to whether religious and medical guiding principles can co-exist and complement in ethical decision-making, without compromising the values.

    Introduction: FertiQoL questionnaire was developed and validated in 2011. It has been widely used and translated
    into many languages to measure QoL among infertile individuals. The use of translated psychometric tools is often
    subjected to cross-cultural variations. The objective of this study is to assess the psychometric properties of the
    Malaysian FertiQoL. Methods: A study was conducted among attendees of a public infertility clinic. Demographic
    details were collected and respondents answered the Malaysian FertiQoL. The questionnaire consists of 34 items.
    Factor analysis and internal consistency were analysed using SPSS v24. Results: Data from 175 respondents were
    analysed. Mean age is 32.1 ±3.8 SD with 56.6% female and 43.4% male. KMO index were 0.826 and significant
    Bartlett’s test for sphericity. For Treatment domain, factor loadings for items T2 and T5 were < 0.32 but for all other
    items were acceptable between 0.32 – 0.80 with no cross loadings and Cronbach alpha for environment (0.717)
    and tolerability (0.660). For Core items, Q4, Q6 and Q14 loaded onto different domains and Q19 had poor factor
    loading. All other items were acceptable. Cronbach alpha for specific domains were emotional (0.788) mind-body
    (0.829), relational (0.639) and social (0.666). Cronbach alpha for emotional, relational, social improved to 0.857,
    0.643 and 0.732 if Q4, Q6 and Q14 were omitted respectively. Conclusion: The study identified six items that affected the psychometric validity of the questionnaire and maybe explained by language or cross-cultural reasons.
    However, the Malaysian FertiQoL can still be useful to measure QoL in those with infertility.
