Zdravotně sociální pohled na infertilitu, možnosti řešení neplodnosti / Health and social aspects of infertility and its treatment

ZAVADILOVÁ, Zuzana January 2007 (has links)
Infertility is the inability to achieve a pregnancy. WHO classify infertility into two groups. Primary infertility is the term used to describe a couple that has never been able to conceive a pregnancy, after at least 1 year of unprotected intercourse. Secondary infertility describes couples who have previously been pregnant at least once, but have not been able to achieve another pregnancy. Causes of infertility include a wide range of physical as well as emotional factors. Approximately 30 - 40% of all infertility is due to a "male" factor such as retrograde ejaculation, impotence hormone deficiency, environmental pollutants, scarring from sexually transmitted disease, or decreased sperm count. A "female" factor -- scarring from sexually transmitted disease or endometriosis, ovulation dysfunction, poor nutrition, hormone imbalance, ovarian cysts, pelvic infection, tumor or transport system abnormality from the cervix through the fallopian tubes -- is responsible for 40 - 50% of infertility in couples. The remaining 10 -30% of infertility cases may be caused by contributing factors from both partners, or no cause can be identified. This dissertation has two main goals. The first goal is to describe how a couple face up to their problems with infertility. The second goal is that this dissertation can be used as a study material for social and medical employees. This dessertation is based on a qualitative research. I used a method CAMI {--} communication through the use of computer. The observational goup were people disccusing at www.neplodnost.cz.

Fórmula combinando idade, contagem de folículos antrais, hormônio antimulleriano e hormônio folículo estimulante é mais acurada em predizer má resposta à estimulação ovariana controlada do que os marcadores isoladamente em pacientes de bom prognóstico / A formula combining age, antral follicle count, antimullerian hormone, and follicle stimulating hormone is more accurate than individual markers in predicting poor response to controlled ovarian stimulation in good prognosis patients

Maurilio Batista Palhares Junior 23 September 2015 (has links)
Apesar da acumulada experiência e tecnologia da reprodução assistida, ainda é comum a ocorrência de má resposta (MR) à estimulação ovariana (EOC). Alguns dos mecanismos que prejudicam a resposta ovariana são conhecidos, como a obesidade e a redução de reserva funcional ovariana com o avançar da idade. No entanto, também se observa má resposta à estimulação ovariana controlada em pacientes jovens e sem comprometimento dessa reserva ovariana. Apesar do desenvolvimento de marcadores para predizer a má resposta, como o hormônio folículo estimulante (FSH), o hormônio antimulleriano (AMH) ou a contagem de folículos antrais (CFA), ainda não há disponibilidade de mecanismos amplamente confiáveis para este fim. Há controvérsias quanto a qual destes preditores apresenta maior acurácia. Esta incerteza é ainda maior quando se analisa a população infértil de aparente bom prognóstico, ou seja, jovens, não obesas e com boa reserva ovariana. Predizer a má resposta neste grupo permitiria importante incremento na qualidade do tratamento destas pacientes. O objetivo deste estudo foi avaliar a acurácia dos marcadores de resposta ovariana como idade, FSH, AMH e CFA e comparar a acurácia destes entre si e combinados em uma fórmula para predizer má resposta à estimulação ovariana controlada em pacientes de bom prognóstico. Foram avaliadas 141 mulheres com idade <40 anos, FSH <10 mUI/ml e índice de massa corpórea (IMC) <30 Kg/m2,, consecutivamente submetidas à injeção intracitoplasmática de espermatozoides (ICSI), a partir de espermatozoides obtidos através de ejaculado. Destas, 45 (32%) obtiveram <3 oócitos e, portanto, tiveram má resposta ovariana. Avaliou-se a acurácia dos marcadores citados em predizer a má resposta através da área sob a curva ROC (AUC). A fórmula obteve AUC = 0.82, valor significativamente superior aos marcadores isolados (idade=0.67, CFA=0.74, AMH=0.75 e FSH=0,61). Também foram definidos os valores de corte para se obter a taxa de detecção de 50% e 80% e analisadas as taxas de verossimilhança dos marcadores. Concluiu-se que a fórmula é mais acurada em predizer má resposta ovariana à EOC do que qualquer dos marcadores isoladamente. / Age, antral follicle count (AFC), antimullerian hormone (AMH) and follicle stimulating hormone (FSH) are frequently used for the prediction of the ovarian response to controlled ovarian stimulation (COS). The objective of this study is to assess the accuracy of a formula combining all these parameters in predicting poor ovarian response (POR) to COS in good prognosis women. We included all good prognosis women submitted to COS for intracitoplasmatic sperm injection (ICSI) between n Feb-2008 and Jan-2009 who accepted to participate. We defined good prognosis as: age <40 years, basal FSH <10 mIU/ml, and body mass index (BMI) <30 Kg/m2; in which the ICSI was performed with sperm obtained by ejaculation. POR was defined as 3 oocytes retrieved or cycle cancelation before oocyte retrieval due to a poor ovarian response. We performed a linear regression to determine a formula to predict POR using age and the logarithm regression of AFC, AMH and FSH. We assessed the predictive accuracy by the area under ROC curve (AUC). Additionally, we determined the cut-off values and false positive rate (FPR) for predicting POR with a detection rate of 50% and 80%. We evaluated 141 women who were submitted to COS and oocyte retrieval; 45 (32%) had POR. The formula to predict poor ovarian response was 0.024 + 0.017*Age - 0.403*LogAFC - 0.339*LogAMH + 0.204*LogFSH. The AUC observed for the formula (0.82) was significantly higher than for the isolated markers (age = 0.67, AFC = 0.74, AMH = 0.75, FSH = 0.61). We also determined the cut-off values and false positive rates for obtaining detection rates of 50% and 80%. We conclude that the formula combining age, FSH, AMH, and AFC is more accurate in predicting POR than individual markers.

Právní a etické aspekty anonymního dárcovství spermatu se zaměřením na právní řád Kanady / Legal and ethical aspects of anonymous sperm donation with focus on the Canadian legal order

Konopásková, Anna January 2016 (has links)
Nowadays, anonymous sperm donation is indeed a globally discussed topic: the popularity of the use of assisted reproduction technology for the purpose of conception is directly proportional to increasing infertility and technological progress. Also, the duration of its use already started to show, with the first generation of opinionated anonymous donor children growing up. The aim of my work is to analyze what are the today's Western society's current ethical and legal views on the anonymous sperm donation and its alternatives, as well as what they should be, and to demonstrate these on the example of Canada, United Kingdom and Australia. In the first two chapters, I outline the context of ethical and legal thinking about anonymous sperm donation: I analyze the concept and implications of the infertility, as well as the development and types of methods of assisted reproduction. Further, I proceed from the basis of ethical reasoning and the determination whether the right to know one's origins, implying the right to know the circumstances of one's conception, exist, and its competition with the rights of parents and donors in the third chapter, to its legal grounds. First, in the fourth chapter, I deal with legislation on the right to know one's origins and other related rights in the international...

“Thanks to a good fairy you were born” : An intersectional feminist analysis of ovum donation advertising found in the public space in Barcelona

Tasa-Vinyals, Elisabet January 2017 (has links)
Gamete donors are actively searched by companies dedicated to assisted reproduction in the Spanish State, and advertising is not only legal but rather common. This thesis provides an overview of the main themes that arise from the analysis of mostly visual materials used to promote ovum donation in public spaces in Barcelona, and critically links them to current debates in intersectional feminist cultural studies of technoscience, bodily theory and visual studies. Conceptual and affective tensions between characterisations of women’s bodies, reproductive function and desires are identified and brought forward in terms that imply tropes of sacralisation, reification of cells/organs/tissues, and fragmentation of the bodily reality. It is argued that egg donation advertisements use an imagery that deeply connects with practices well rooted in Western biomedical traditions when it comes to female bodies, physiology and reproductive function, and that such practices are to be understood against the backdrop of neoliberalism. The analysis supports the idea that the publicity discourse of the assisted reproduction industry in Spain actively engages in a legitimation of the desire of biological parenthood as a right, in ways that value lives conceived in different circumstances and geopolitical contexts in radically different ways, and that can be interpreted as paving the way to prosurrogacy and/or eugenic positions. Future research is encouraged and directed towards exploring issues of agency, particularly in vulnerable groups such as migrant, poor, uneducated or racialised women. Further research is needed in order to build the foundations of a feminist ethical reflection on reproductive technologies and particularly of ovum donation.

The constitutional and contractual implications of the application of chapter 19 of the Children's Act 38 of 2005

Lewis, Samantha Vanessa January 2011 (has links)
Magister Legum - LLM / In this research, I carefully and coherently examine Chapter 19 of the Children's Act 38 of 2005 as the first legislation to afford surrogate motherhood agreements legal recognition in South Africa. I argue that the application of Chapter 19 imposes a number of unwarranted limitations on several of the constitutional rights of the parties to a surrogacy agreement. In addition, I propose that Chapter 19 is not in accordance with the principal of the best interests of the child. I examine the history of surrogate motherhood in South Africa and establish that, prior to the enactment of Chapter 19, no legislation expressly afforded surrogate motherhood agreements legal recognition. Hence, prior to the enactment of Chapter 19, parties who entered surrogacy agreements could, first, not rely on the agreement to enforce contractual obligations, and secondly, the legal positions of the parties to the agreement were uncertain. Thirdly, a child born of a surrogacy agreement was seen as the child of the surrogate mother and not of the commissioning parents. / South Africa

Essai sur le don d'ovocytes : questionnements éthiques dans le monde d’aujourd’hui / Egg donation : questionings ethiques in the world of today

Chevallier, Betty 19 December 2011 (has links)
Les nouvelles pratiques d’aide médicale à la procréation, notamment celle qu’on appelle « le don d’ovocyte » bouleverse le sens de la parentalité. Elle oblige chacun d’entre nous à expliciter ses conceptions de la vie, à énoncer ses priorités, mais elle oblige aussi la collectivité à prendre conscience d’elle-même et de ce qui peut être acceptable. Est-il moralement satisfaisant qu’une femme donne ses ovocytes pour qu’une autre ait un enfant ?En interrogeant 50 donneuses d’ovocytes, ce travail a cherché à mieux comprendre la signification d’un tel geste.La procréation par don, défie nos habitudes et nos manières de penser. Elle nous réinterroge sur notre capacité de fraternité comme réponse d’un appel de l’un pour l’autre, elle cherche à donner une juste place à ce tiers-donneur qui s’insinue (presque malgré lui) dans un arbre généalogique. Elle bouleverse notre rapport à l’enfant qui se pose comme « un ayant droit à connaître ses origines ». En définitive, ce n’est pas tant la question de l’anonymat du don qui nous importe que ce qu’il en est de l’homme, de son altérité et de ses responsabilités / Reproductive technology, in particular oocyte or egg donation, upsets the meaning of parenthood and raises questions about the circumstances surrounding those who decide to have a child by means of this technology. A woman using egg donation must come to grips with questions such as the meaning of life, and what it means to be a mother. But it also requires that society become aware of what is morally acceptable. Is it morally acceptable for the egg donor to give her eggs to anotherwoman who wants to have a child? We would like to gloss over these issues by the power of love or by the growth of the uterus, but these issues will remain in the minds of everyone and will circulate in the subconscious. The purpose of this essay is to grapple with these issues. Reproduction by gift, it challenges our habits and ways of thinking. It causes us to re-examine the companionship among two people, it creates a role for the egg donor who, almost despite herself, inserts herself into the family tree. It disrupts the relationship being the parents and the child who demands the right to know where they came from. Ultimately, the focus rests not on the anonymity of the egg donor but on the father, his otherness and his responsibility.

”Alltså jag ser ju mest positivt, ju mer jag ser desto mer positivt ser jag” : En kvalitativ intervjustudie om upplevelsen av frivilligt ensamstående föräldraskap via assisterad befruktning i Sverige / A qualitative interview study about the experience of single motherhood by choice through assisted reproduction in Sweden

Jönsson, Linnéa, Lennartsson, Matilda January 2020 (has links)
Syftet med den aktuella kvalitativa studien var att belysa frivilligt ensamstående föräldrars (FEF) upplevelser för att bidra till ökad förståelse och kunskap om hur det är att överväga, bli och vara FEF. Sju semistrukturerade intervjuer genomfördes och analyserades genom tematisk analys, vilket resulterade i fem huvudteman: Så upplevs FEF-skapet, Ta steget att bli FEF, Stöd från ett nätverk är viktigt som FEF, Hur FEF blir bemötta av sin omgivning och Tankar om framtiden. Mödrarna upplevde FEF-skapet som övervägande positivt och enklare än förväntat. Både för- och nackdelar nämndes och stöd från ett nätverk beskrevs vara extra viktigt. Mödrarna var medvetna om att de bryter mot kärnfamiljsnormen. Från omgivningen hade de mestadels mött positiva reaktioner men även en del negativa reaktioner och fördomar, främst rörande avsaknaden av en pappa. Mödrarna uppgav olika skäl till att bli FEF och beslutsprocessen rapporterades övervägande som enkel. Samtidigt uttrycktes viss ambivalens då FEF inte var deras förstahandsval, men ansågs mest optimalt utifrån deras förutsättningar. / The aim of this qualitative study was to make visible the experiences of single mothers by choice (SMC) with the purpose of contributing to increased understanding and knowledge of what it is like to consider, become and be a SMC. Seven semi-structured interviews were conducted and analyzed through thematic analysis, resulting in five main themes: The experience of motherhood as SMC, Making the choice to become SMC, Support from a network is important as SMC, How SMC is met by their surroundings and Thoughts on the future. The mothers perceived motherhood as SMC as mostly positive and easier than expected. Both advantages and disadvantages were mentioned and support from a network was described as especially important. The mothers were aware that they are violating the nuclear family norm. From their surroundings, they had mostly encountered positive reactions but also some negative reactions and prejudices, mainly concerning the absence of a father. The mothers stated different reasons for becoming SMC and the decision-making process was predominantly reported as simple. At the same time, some ambivalence was expressed as motherhood as SMC was not their first hand choice, but was considered the best choice based on their situation.

Etická problematika asistované reprodukce s důrazem na metody kryokonzervace / Ethical issues of assisted reproduction with emphasis cryopreservation methods

Zajíčková, Markéta January 2018 (has links)
Human infertility is not a new phenomenon, but it is as old as humanity itself. Currently in most developed countries, the number of couples who have a problem with childbearing is growing. This is due, among other things, to the lifestyle associated with career development and postponement of parenthood. While in the past infertile couples usually had only two options to deal with their sterility - childlessness and a substitute life program, or adopting a child. Today, infertile couples have a third option and this is the treatment of infertility using assisted reproduction methods. This year, exactly forty years have elapsed since the birth of the first child by means of extracorporeal fertilization. Already then the assisted reproduction was considered a method that is ethically problematic. Numerous specialists, such as physicians, biologists, lawyers, philosophers, theologians, and others, have been involved in the quest for ethical issues. Not only there has been no solution to some problems during the whole lifetime of assisted reproduction on which most experts and the general public would agree, but with the gradual development of this treatment method new problems have arisen. Today's stage of development of artificial insemination techniques and procedures together with modern...

Zkušenost neplodnosti: retrospektivní biografická rekonstrukce nyní plodných žen / Infertility experience: retrospective biographical reconstruction of now fertile women

Ulrichová, Eva January 2020 (has links)
This master's thesis focuses on the retrospective biographical interviews with three now fertile women who as narrators retrospectively create their identities during the experience with the diagnosis and treatment of infertility. I also explored how the medical and social institution could lead to a change of identity of female infertility. This master's thesis is based on theory of Erving Goffman about patients in total institution: this theory supports the idea that total (medical) institution destroys the patient's original identity and then constructs new identity. The major result of this master's thesis found four different changes in woman's identity during the experience of infertility: identity of implicitly fertile woman and potential mother, denial of identity and the process of accepting a new identity, identity of infertile woman and patient's identity, and mother's identity. The changes of woman's identity are based on diagnostic phase. Therefore I decided to separate them into four various period in this research: pre-diagnostic, diagnostic, post-diagnostic and contra-diagnostic. I also found a difference between Goffman's theory and my results: Based on my research I concluded that the construction of identity of infertile women in the diagnostics and treatment of infertility is...

La pratique infirmière en procréation médicalement assistée au sein d’un établissement de santé québécois : une étude autoethnographique

Guay, Martine 12 1900 (has links)
Problématique : L’infertilité – considérée par l’Organisation mondiale de la santé (OMS) comme une maladie du système reproducteur – affecte de plus en plus d’hommes et de femmes, soit un couple sur six en âge de procréer au Canada et au Québec. Elle a un impact sur le bien-être physique et mental des patient.e.s, souvent stigmatisé.e.s et isolé.e.s socialement parce que, pour plusieurs, l’infertilité demeure un sujet tabou. L’infertilité est traitée en procréation médicalement assistée (PMA) où les patient.e.s-familles sont accompagné.e.s par des infirmières dont la pratique est complexe et diversifiée, mais méconnue. But : L’étude avait pour but d’explorer la pratique infirmière en PMA dans un établissement de santé québécois. Méthode : Le devis retenu est une autoethnographie où l’étudiante-chercheuse a mis à profit son expérience comme patiente et comme infirmière en PMA. Des entretiens semi-dirigés, une observation participante et un journal de terrain ont été employés pour la collecte des données. Une analyse thématique a été réalisée. Résultats : L’expérience des patient.e.s-familles en infertilité est au cœur de la pratique infirmière et l’une des principales dimensions de cette pratique est le soin relationnel, peu importe les sphères d’activités auxquelles les infirmières sont affectées au sein de la clinique. Les autres dimensions rapportées sont le leadership/advocacy, l’apprentissage/enseignement, la collaboration et les interventions techniques. Ces résultats correspondent à l’expérience de l’étudiante-chercheuse, tant à titre de patiente que d’infirmière en PMA. Retombées : L’étudiante-chercheuse a documenté la pratique infirmière en PMA, mettant en valeur une méthode peu usitée en sciences infirmières : l’autoethnographie. / Problem: Infertility – classified by the World Health Organization (WHO) as a reproductive system disease – affects an ever-increasing number of women and men. Today, one couple out of six of reproductive age struggles with this condition in Canada and in Quebec. It has an impact on the patients’ physical and psychological well-being, often leaving both partners stigmatized and socially isolated as infertility remains a societal taboo for many. Infertility can be treated via Assisted Reproduction Technologies (ART) where the patients-families are cared for by fertility nurses, whose practice is both complex and diversified, but remains little-known. Purpose: This study explores the field of fertility nursing as it is practised in a Quebec healthcare institution. Method: The student-researcher chose to do an autoethnography in order to draw from her own experience as both a fertility nurse and a fertility patient. Semi-directed interviews, participant observation and field journal were used to collect data. A thematic analysis of data then followed. Results: The patients-families’ infertility experience is at the heart of the fertility nurse’s practice and relational care is the main dimension of that practice, regardless of which nursing activities are assigned to them in the clinic. These other dimensions were also reported : leadership/advocacy, learning/teaching, collaboration and technical interventions. These results coincide with the student-researcher’s experience, both as a fertility patient and as a fertility nurse. Impact: The student-researcher documented the practice of fertility nursing and showcased a method rarely used in nursing science: autoethnography.
