Abstract:

Genome instability may play a role in severe cases of male infertility, with disrupted spermatogenesis being just one manifestation of decreased general health and increased morbidity. Here, we review the data on the association of male infertility with genetic, epigenetic, and environmental alterations, the causes and consequences, and the methods for assessment of genome instability. Male infertility research has provided evidence that spermatogenic defects are often not limited to testicular dysfunction. An increased incidence of urogenital disorders and several types of cancer, as well as overall reduced health (manifested by decreased life expectancy and increased morbidity) have been reported in infertile men. The pathophysiological link between decreased life expectancy and male infertility supports the notion of male infertility being a systemic rather than an isolated condition. It is driven by the accumulation of DNA strand breaks and premature cellular senescence. We have presented extensive data supporting the notion that genome instability can lead to severe male infertility termed “idiopathic oligo-astheno-teratozoospermia.” We have detailed that genome instability in men with oligo-astheno-teratozoospermia (OAT) might depend on several genetic and epigenetic factors such as chromosomal heterogeneity, aneuploidy, micronucleation, dynamic mutations, RT, PIWI/piRNA regulatory pathway, pathogenic allelic variants in repair system genes, DNA methylation, environmental aspects, and lifestyle factors.

Abstract:

The intensification of oxidative stress and destabilization of the antioxidative defenses of an organism is a consequence of many environmental factors. We considered aspects conditioning male reproductive potential and the functionality of enzymatic antioxidative mechanisms, i.e., superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and glutathione reductase (GR), and their correlations with Li, Be, B, Na, Mg, Al, P, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Sr, Mo, Ag, Cd, Sn, Sb, Ba, Hg, Tl, Pb, and malondialdehyde (MDA), as well as genetic polymorphism IL-4v.C589T (rs2243250) in men with infertility (n = 76). A healthy normozoospermic control (n = 87) was also used. We assessed the impact of negative changes driven by oxidative stress on enzymatic antioxidative mechanisms as well as the role of MDA in the overall process. On this basis, we infer connections between disturbances in enzymatic antioxidative defense and reproductive potential. Based on a molecular analysis of the polymorphism of gene IL-4v.C589T (rs2243250) (chromosome 5) (PCR-RFLP), we considered the relationships among particular genotypes with the possibility of occurrence of male infertility. Concentrations of chemical elements were measured in the blood. The activity of antioxidants and MDA levels were measured in serum. In the infertile group, higher GPx activity was noted (6.56 nmoL·min−1·mL−1, control: 4.31 nmoL·min−1·mL−1; p = 0.004), while GR achieved a greater level in the control (17.74 nmoL·min−1·mL−1, infertile: 15.97 nmoL·min−1·mL−1, p = 0.043), which implies diversified efficiency of the first and second lines of defense. The polymorphism of IL-4v.C589T (rs2243250) was not directly connected with infertility because there were not any differences in the frequency of genotypes between the infertile and control group (p = 0.578). An analysis of genotypes CC and TT (polymorphism IL-4v.C589T (rs2243250) indicated numerous correlations between antioxidants, chemical elements and MDA. Therefore, chemical economy, antioxidative defense and genetic conditions are connected and jointly shape male reproductive potential. Chemical elements influence antioxidative defense and male fertility; the most important modulators appeared to be Na, Ba, Al and B. The polymorphism of gene IL-4v.C589T (rs2243250) has a limited influence on antioxidative defense and the metabolism of chemical elements.

Abstract:

Objective: to establish a correlation of the main neuroendocrine and metabolic parameters associated with infertility and to provide a prognostic assessment of reproductive disorders in HIV-infected women, stages 4.Materials and methods. Cross-sectional, cohort, clinical and sociological study of fertility of 83 women of reproductive age with HIV, stages 4.Results. The most signiﬁcant indicators of lipid peroxidation and neuroendocrine regulation systems have been established in patients with HIV infection and reproductive disorders, which will make it possible to predict these disorders in the future. Decreased ovarian reserve, ovarian steroid function, increased pituitary prolactinergic function are associated with a deﬁciency of a number of antioxidants (retinol, tocopherol, superoxide dismutase) and the development of oxidative stress with a predominant accumulation of intermediate lipid peroxidation products in HIV-infected women with infertility.Conclusion. The pathogenetically substantiated principle of the correction of antioxidant status is the use of a-tocopherol and retinol preparations and the correction of hormonal levels in HIV-infected women with reproductive disorders.

Abstract:

Laparoscopic surgery was originally considered the gold standard in the treatment of endometriosis-related infertility. Assisted reproductive technology (ART) was indicated as second-line treatment or in the case of male factor. The combined approach of surgery followed by ART proved to offer higher chances of pregnancy in infertile women with endometriosis. However, it was highlighted how pelvic surgery for endometriosis, especially in cases of ovarian endometriomas, could cause iatrogenic damage due to ovarian reserve loss, adhesion formation (scarring), and ischemic damage. Furthermore, in the last few years, the trend to delay the first childbirth, recent technological advances in ultrasound diagnosis, and technological progress in clinical and laboratory aspects of ART have certainly influenced the approach to infertility and endometriosis with, ART assuming a more relevant role. Management of endometriosis should take into account that the disease is chronic and involves the reproductive system. Consequently, treatment and counselling should aim to preserve the chances of pregnancy for the patient, even if it is not associated with infertility. This review will analyse the evolution of the management of infertility associated with endometriosis and propose an algorithm for treatment decision-making based on the most recent acquisitions.

Abstract:

Infertility is a global health issue affecting women and men of reproductive age with increasing incidence worldwide, in part due to greater awareness and better diagnosis. Assisted reproduction technologies (ART) are considered the ultimate step in the treatment of infertility. Recently, artificial intelligence (AI) has been progressively used in the many fields of medicine, integrating knowledge and computer science through machine learning algorithms. AI has the potential to improve infertility diagnosis and ART outcomes estimated as pregnancy and/or live birth rate, especially with recurrent ART failure. A broad-ranging review has been conducted, focusing on clinical AI applications up until September 2022, which could be estimated in terms of possible applications, such as ultrasound monitoring of folliculogenesis, endometrial receptivity, embryo selection based on quality and viability, and prediction of post implantation embryo development, in order to eliminate potential contributing risk factors. Oocyte morphology assessment is highly relevant in terms of successful fertilization rate, as well as during oocyte freezing for fertility preservation, and substantially valuable in oocyte donation cycles. AI has great implications in the assessment of male infertility, with computerised semen analysis systems already in use and a broad spectrum of possible AI-based applications in environmental and lifestyle evaluation to predict semen quality. In addition, considerable progress has been made in terms of harnessing AI in cases of idiopathic infertility, to improve the stratification of infertile/fertile couples based on their biological and clinical signatures. With AI as a very powerful tool of the future, our review is meant to summarise current AI applications and investigations in contemporary reproduction medicine, mainly focusing on the nonsurgical aspects of it; in addition, the authors have briefly explored the frames of reference and guiding principles for the definition and implementation of legal, regulatory, and ethical standards for AI in healthcare.

Abstract:

Background: Childlessness is a very pain full situation. It affects both partners but more to females. Burden of secondary infertility is more than primary infertility but it is not captured properly. Secondary infertility also has significant psychological, personal and marital sufferings. Social pressures add the anxiety if only daughters are born. Aim: To find out the reproductive characteristic features of patients presenting with secondary infertility. Place and duration: This retrospective cross sectional study was conducted in Health Care Center Hospital (Pvt) Ltd from July 2021 to September 2022. Method: All patients with secondary infertility of more than one year were included who had previous one or more spontaneous conceptions irrespective of pregnancy outcome. Patients who had no record of previous pregnancies and those who conceived after infertility treatment were excluded. Clinical history was checked from patient’s files and delivery registers. Data was entered in preformed Performa and analyzed by SPSS Version 20. Frequencies were calculated by percentages. Results: Total 115 patients with secondary infertility were included. Sixty one patients had one or more parity, 54 patients had miscarriages. Fifty eight patients had alive babies and 3 babies died. Among 58 live babies 40 patients had only females, 12 had only male and 6 had both male and female children. Among 61 para women, forty three patients had vaginal delivery, 33 normal vaginal and 10 were instrumental deliveries. Cesarean Section was done in 18 patients, 13 were emergency and 05 elective C/S. Practical implication This study will help to understand the burden and factors contributing to secondary infertility. This will guide to manage those factors so that to lesson the secondary infertility. Conclusion: Secondary infertility is an important issue in gynaecological clinics. These patients usually have some identifiable risk factors. Their case should be reviewed carefully to find out the risk factors for proper management.

Abstract:

Infertility is a problem that affects millions of couples around the world. It is known as a disease of couples, not individuals, which makes diagnosis difficult and treatment unclear. Male infertility can have many causes, from mechanical ones to abnormal spermatogenesis or spermiogenesis. Semen quality is determined by a number of factors, including those dependent on men themselves, with the number of infertile men growing every year. These include, e.g., diet, physical activity, sleep quality, stress, among many others. As these factors co-exist with insulin resistance, which is a disease closely related to lifestyle, it has been singled out in the study due to its role in affecting semen quality. In order to examine connections between lifestyle, insulin resistance, and semen quality, a review of literature published from 1989 to 2020 in the following databases PubMed/Medline, EMBASE (Elsevier), Scopus, Web of Science, and Google Scholar was performed. Hence, semen quality, environment, and insulin resistance are interrelated, thus it is difficult to indicate which aspect is the cause and which is the effect in a particular relationship and the nature of possible correlations. Since the influence of lifestyle on semen quality has been extensively studied, it is recommended that more thorough research be done on the relationship between insulin resistance and semen quality, comparing the semen quality of men with and without insulin resistance.

Abstract:

Much of the early work on Nuclear Hormone Receptors (NHRs) focused on their essential roles as mediators of sex steroid hormone signaling in reproductive development and function, and thyroid hormone-dependent formation of the central nervous system. However, as NHRs display tissue-specific distributions and activities, it is not surprising that they are involved and vital in numerous aspects of human development and essential for homeostasis of all organ systems. Much attention has recently been focused on the role of NHRs in energy balance, metabolism, and lipid homeostasis. Dysregulation of NHR function has been implicated in numerous pathologies including cancers, metabolic obesity and syndrome, Type II diabetes mellitus, cardiovascular disease, hyperlipidemia, male and female infertility and other reproductive disorders. This review will discuss the dysregulation of NHR function by environmental endocrine disrupting chemicals (EDCs), and the associated pathological consequences of exposure in numerous tissues and organ systems, as revealed by experimental, clinical, and epidemiological studies.

Abstract:

The aim of this study was a retrospective evaluation of the reproductive health of the male staff of the Kalinin and Kursk nuclear power plant (NPP). Material and Methods. Fertility indices were used for the evaluation of the reproductive health status (ability to have children) and the health status of their offspring. For the assessment of the fertility there were used data concerning the marital status, childbirths and radiation doses received by males, obtained from the questionnaires, developed as part of this study. The data about the health of newborns was obtained from information copied from the individual cards of pregnant history cases and infant history case. In total, in the study there was analyzed data on the marital status of 679 men from Kalinin and 631 men from Kursk NPP, as well as data on the 735 and 813 newborn in the families of staff of the Kalinin and Kursk NPP, and data on 1438 and 1284 pregnant women respectively. As control groups there were used data about health of newborns and pregnant women of cities of Udomlya and Kurchatov. The combined groups included 1549 newborns and of 2718 pregnant women. Results. Infertile marriages due to the male infertility accounted for 7.3% of the Kalinin NPP personnel, and 2.5% -of Kursk NPP personnel. The incidence and complication rates of the pregnancy in families of Kalinin and Kursk NPP staff are comparable with those in the control group of pregnant women and were 75.7%, 61.6% and 71.0%, respectively. Adverse pregnancy outcomes (spontaneous abortions and early neonatal death of the newborn) were recorded in 6.9%, 0.1% in the families of the personnel of the Kalinin NPP and 8.9%, 0.2% in the families of the personnel Kursk of the NPP complying with the control values of 7.6% 0.2%, respectively. The frequency of the birth of the health child corresponds to control values as 73.6% of the families of the personnel of the Kalinin NPP, amounting to 65.3% in the families of the personnel of the Kursk NPP and 69.7% in the control group. The relative risk of birth of a child with congenital malformations RR = 0,84 in the families of staff at Kalinin NPP and RR = 1.0 - at Kursk NPP. Conclusion. No impact of occupational exposure on the reproductive health was revealed for the male staff both at Kalinin and Kursk NPP.

Abstract:

Introduction. Surrogacy is a method of infertility treatment involving the conclusion of an agreement between potential parents, a surrogate mother and a medical institution. Until now, lawyers have not been able to develop a unified approach to forming the regulatory framework for surrogacy. Whether healthcare providers have developed a standard view of this problem is not clear. The purpose is to summarise the medical community representatives’ views on the surrogacy program’s managing issues and their participants’ rights and obligations. Material and methods. The Internet survey was conducted among medical workers of various specialisations from different regions of Russia and among future specialists (students of medical universities and interns). 7504 questionnaire was analysed. The questions concerned the indications for surrogate motherhood, the sources of its funding, the citizenship of the participants in surrogacy and their contractual obligations, the rights of the surrogate mother and the ordering parents. Results. medical specialists assign a pivotal role to the surrogacy program’s legal aspects, despite being implemented using high-tech medical technologies. They give priority rights to a newborn child to the ordering parents. During pregnancy and childbirth, decisions regarding lifestyle, hospitalisation, and delivery methods should be made only in conjunction with specialists from the medical institution that signed the contract. As the level of professional responsibility of medical specialists grows, the share of answers about the inadmissibility of state funding of surrogacy, the implementation of surrogacy programs for foreign citizens and single men and women as genetic donors increases, and the share of answers about the admissibility of altruistic surrogacy decrease. Conclusion. Having decided on the legal issues of managing medical care in surrogacy programs, representatives of the medical community do not consider this type of high-tech medical care a common way to solve the problem of infertility, considering it as an exclusive method of medical care for married couples with infertility of women.

Abstract:

This dissertation revolves around three main elements: 'male infertility'; existing social science research on infertility; and ethno methodology. The substantive topic 'male infertility' is enclosed in quotation marks for two reasons. First, following the overall form of ethno methodological inquiry, the aim is to explicate how the sense and order of 'male infertility' is constituted through available socially organised procedures; hence, the quotation marks are used to 'bracket' the phenomenon and focus on the methods that make it available. Second, 'male infertility' is a convenient shorthand topic label, a general organising concept, as opposed to a precise label for a tightly defined phenomenon. While this study's approach makes it very different to existing sociological studies of infertility, the difference is not to the extent of isolation - a strong attempt is made to engage with prior studies. Often this engagement takes a critical form, the general argument being that sociological studies which approach phenomena for the way they 'bear the marks' of societal structures, will ignore the incarnate orderliness of social action - that is, the way social action is readily explicable to members, in and as it occurs, using the resources at-hand, with 'no time-out'. Ethno methodology suggests that this ready explicability is based upon taken-for-granted, socially organised sense-assembly practices - thus, this study's argument that the content, the intelligibility of 'male infertility is interdependent with the social scenes and embedded socially organised procedures, with and within which 'male infertility' is found. Form and content stand or fall together. Consistent with this viewpoint, four empirical analyses of the social organisation of 'male infertility' are offered. The specific topics discussed are: the conversational disclosure of infertility; the language of reproduction; humour and infertility; and high rates of non-response by men in studies of infertility. In general, the empirical analyses are 'indifferent' to the topic of study, that is, there is no overriding aim of offering practical correctives or broader socio-political critique. However, in at least one empirical chapter a more critical stand is taken, and, in the concluding chapter, it is argued that an ethno methodological descriptivist approach can have socio-political implications. Overall, the study supports the growing trend for ethno methodological insights to be utilised in the study of substantive topics; and, since the dissertation is a form of writing 'anew', it can be considered to minimally change 'male infertility' as a form of life.

Abstract:

It has been estimated that approximately 15% of couples attempting to attain pregnancy are unable to do so. A female factor is the primary aetiology in nearly 40% of these couples and in another 30% the factors are purely male. A combmation of male and female factors has been implicated for the remaining 30% of cases. Infertility is a common problem among men with testicular cancer. Such men are especially affected by infertility and they often decide to undergo sperm banking (the collection and freezing of sperm) before beginning chemo/radiotherapy.

Abstract:

Thesis (MTech (Biomedical Technology))--Cape Peninsula University of Technology, 2015.
Diabetes mellitus (DM) has been reported to be one of the greatest global public health threats. Statistics of the fertility status of modern society has linked increased DM to a decrease in fertility rates. Hyperglycaemia is characteristic of DM that results in a disturbance of proteins, lipids and carbohydrate metabolism leading to an increase production of reactive oxygen species (ROS). In the case where ROS overwhelms antioxidant mechanisms, the body goes into state of oxidative stress (OS). OS plays a vital role in the progression of DM which leads to dysfunction and damage of various organs including that of the reproductive system. Os has shown to cause damage to the sperm membraneby oxidation of polyunsaturated fatty acids (PUFA’s) as the sperm membrane are rich in PUFA’s. This damage contributes to reduced sperm motility, concentration, morphological abnormalities and the sperms ability to fuse with the ZP of the oocyte. DM has been observed to cause testicular degeneration by interrupting sertoli cell production and maintenance thus resulting in a disturbance of the normal functioning of the reproductive system. Experimental studies have targeted more natural sources for treating DM and its complications of the reproductive system. Plants and natural dietary substances have shown to have high antioxidant contents that combat DM induced oxidative stress. This study explored the effect the Hypoxis hemerocallidea (H. hemerocallidea) supplementation on testicular and epididymal tissue, sperm motility and reproductive hormones in male wistar rats. The experiment were conducted for 6 weeks and the rats (230-260 grams) were randomly divided into 5 groups (n=12 per group). Diabetes was induced in 3 of the 5 groups. The first group was the normal control group (A), second the diabetic control group (B), third was the diabetic group treated with 800mg/kg H. hemerocallidea (group C), fourth the diabetic group treated with 200mg/kg H. hemerocallidea (group D) and fifth the non-diabetic group supplemented with 800mg/kg H. hemerocallidea (group E). Blood glucose showed a significant increase in the diabetic group when compared to the normal control and treated groups. H. hemerocallidea showed improvement in sperm motility and sperm morphology more at 800mg/kg when compared to diabetic group and diabetic group treated with 200mg/kg. Body, testicular and epipidymal weights of diabetic control were significantly lower when compared to the other groups. Testicular and epididymal Malondialdehyde levels were decreased in normal control, diabetic groups treated with different doses of H. hemerocallidea and the non-diabetic group supplemented with H. hemerocallideaon comparing with the diabetic control group. Antioxidants such as Superoxide dismutase, Catalase and total Glutathione activity was observed to be dosage dependent in certin groups but most showed a significant increase when compared to the diabetic control group. The total antioxidant capacity was measured using Oxygen radical absorbance capacity (ORAC) and Ferric ion reducing antioxidant power (FRAP); increase was observed when normal control group and treated groups were compared to the diabetic group. Testosterone and estradiol levels were also increased when the normal control group and treated groups were compared to the diabetic control group. Based on our findings it can be concluded that H. hemerocallidea supplementation can potentially be used to counteract deleterious effects of DM on the male reproductive system.

Abstract:

A presente pesquisa teve como objetivo geral compreender a experiência de homens que vivenciam a infertilidade. E, especificamente, enfocou interpretações da masculinidade e infertilidade, contextualizando-as na contemporaneidade; apresentou a perspectiva fenomenológica existencial como possibilidade para tematizar o fenômeno do corpo enquanto expressão da existência; bem como descreveu e compreendeu a experiência de homens, na condição de inférteis, os quais procuram o serviço de Reprodução Humana Assistida do Instituto de Medicina Integral de Pernambuco IMIP. De natureza qualitativa, esta investigação está afinada à perspectiva fenomenológica hermenêutica, privilegiando a compreensão interpretativa fundada na Hermenêutica Filosófica de Gadamer, vinculada às compreensões ontológicas heideggerianas. Para acesso à experiência foi escolhida a narrativa, colhida tanto dos colaboradores, quanto dos registros feitos no diário de bordo da pesquisadora, a partir da sua inserção no lócus da pesquisa. Os relatos dos colaboradores apontaram para dificuldades vividas durante a tentativa de métodos de Reprodução Assistida, as quais levaram a experiências de desconforto, bem como de desesperança frente a burocracia e morosidade dos serviços. Aproximando-se desta via compreensiva, a possibilidade de procriação artificial foi revelada com certa estranheza, ressaltando a supervalorização da parentalidade biológica. Em tal cenário, os interlocutores narraram sua vivência frente aos procedimentos técnicos/médicos, desvelando de um lado a utilidade da técnica no projeto parental e, de outro, o seu domínio na hegemonia do discurso científico, bem como na compreensão do corpo masculino como matéria-prima a ser explorada e aperfeiçoada.
The present research had the aim to understand the experience of infertile men. Specifically, it focused on masculinity and infertility interpretations, contextualizing them in contemporaneity; it also presented an existential phenomenological perspective as a possibility to thematize the body phenomenon as an expression of existence; as well as it described and understood the experience of infertile men who searched for the Assisted Human Reproduction service from the Institute of Integral Medicine of Pernambuco IMIP. This investigation is of qualitative nature, linked to the hermeneutic phenomenological perspective that privileges Gadamers Philosophical Hermeneutic and Heideggerian ontological comprehensions. Narratives from collaborators and from the researchers field journal were used in order to access such experience. Collaborators reports pointed to difficulties during the attempt for Assisted Reproduction methods, which led to uncomfortable experiences, as well as a lack of hope face to the services bureaucracy and slowness. The possibility of artificial procreation was revealed with certain awkwardness, with highlights to the over-valorization of biological parenthood. In such scenario, interlocutors narrated what they have lived regarding technical/medical procedures, unveiling, on one side, the utility of the technique for the parental project and, on the other side, the domain of scientific discourse, as well as the comprehension of mens bodies as raw material to be explored and improved.

Abstract:

Vitellogenin in Pimephales promelas was used to assess estrogenicity of a local municipal effluent. Vitellogenin induction in male P. promelas increased in frequency and magnitude with increased exposure duration and was greater ("=0.05) than controls after 2 and 3 weeks of exposure. The level of vitellogenesis induced by effluent exposure was high compared to similar studies. A spring season evaluation followed. Biomarkers in P. promelas were used to assess the efficacy of a treatment wetland to remove toxicity and estrogenicity in final treated wastewater effluent. Comparisons were made with an effluent dominated stream and laboratory controls. Vitellogenin, GSIs (gonado-somatic indices), HSIs (hepato-somatic indices) and secondary sexual characteristics were biomarkers used in P. promelas models to assess aqueous estrogenicity. Biological indicators used to assess general fish health included hematocrit and condition factors. The estrogenic nature of the effluent was screened, concurrent with fish exposure, with GC/MS analysis for target estrogenic compounds including: 17-b estradiol, estrone, ethynylestradiol, Bisphenol A, nonylphenolic compounds, phthalates, and DDT. Plasma vitellogenin measured in P. promelas was significantly elevated (p < 0.0001) at the inflow site of the wetland and stream sites. GSIs for these exposures were less (a=0.001) at the wetland inflow site. At wetland sites closest to the inflow, secondary sexual charateristics, tubercle numbers and fat pad thickness, were less (a=0.0001). Hematocrit and condition factors were less (a=0.001) at sites closer to the wetland inflow. Seasonal variation was examined by repeating the effluent characterization in summer. Additionally, summer testing included exposure to an effluent dilution series. Fish condition heavily influenced interpretation of the results. Pre-acclimation exposure to spawning stresses may have altered many of the biological markers measured. Results are discussed relative to fish health and pre-exposure environment. Toxicity assessed with P. promelas biomarkers was compared with Ceriodaphnia dubia and Vibrio fischeri toxicty tests on this effluent. Biomarkers of fish health were somewhat less sensitive than C. dubia test endpoints, but more sensitive than V. fisheri.

Abstract:

It has been well documented that the ageing, male dominated profile of the workforce in the UK nuclear industry will not support the forecasted nuclear renaissance. Based upon the aspects of age, gender and level of education, there is an existing shortfall in available knowledgeable resource to undertake and manage the extensive new build, operational and decommissioning programmes. The 2005 Nuclear Employers Survey advised the industry to recruit and train more: • young and qualified people. • experienced and qualified people from outside the industry. The future for the UK nuclear industry lies with people in their 20s and 30s. It is essential that not just technical talent but also managerial talent be identified early and that they are nourished and allowed to flourish.

Abstract:

Ergonomic conditions and workers comfort during L-shaped desk usage in an occupational environment has not been extensively studied in the literature. Thus, the objective of this study was to describe how workers have spontaneously positioned their VDUs on L-shaped desks and to analyze related ergonomic aspects of the workstation and the worker’s comfort. Thirteen females and one male VDU worker were observed by a physiotherapist ergonomist during their working time and their comfort was evaluated when using the desk on an 11 point scale. Eight workers positioned the VDU on the concave edge of the desk and seven of them reported high levels of comfort. The main reason for workers positively evaluating this desk was the extra space provided by the desk, which increases the working area in relation to the traditional ones. Workers who evaluated their comfort as lower than 7 (n=6) usually maintained the VDU either on the straight part of the desk or on an intermediate area between the concave and the straight part of the desk (n=5). Observations performed during work revealed the need for environmental, organizational and ergonomic rearrangements of the workstation aiming to prevent musculoskeletal disorders among workers who use L-shaped desks.
