  1. 1. Sammanhangets mening : En empirisk studie av livsåskådningar i föreställningar om genteknik och i berättelser om barnlöshet, assisterad befruktning och adoption

    Sammanfattning : This present thesis explores the meaning of contexts for views of life. The first aim of the investigation is to describe the existential meaningful content of views of life in perceptions of gene technology and in narratives about childlessness, assisted conception and adoption, as they are articulated in two separate sets of interviews.

    Sammanfattning : Infertility affects 15% of reproductive-aged couples. The milieu surrounding the growing embryo is of outmost importance, and should be optimised during in vitro fertilisation (IVF). Many biological processes, such as angiogenesis, coagulation, and immune processes need to be well regulated for a pregnancy to occur and progress normally. LÄS MER

  3. 3. Ovarian hyperstimulation syndrome (OHSS). Aspects on immune and endocrine mechanisms

    Författare :Anders Enskog; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; controlled ovarian hyperstimulation; cytokine; inhibin; interleukin-10; in vitro fertilisation; ovarian hyperstimulation syndrome; nitric oxide; vascular endothelial growth factor;

    Sammanfattning : The ovarian hyperstimulation syndrome (OHSS) is a well-known side effect of ovarian stimulation for ovulation induction or for in vitro fertilisation. The syndrome is characterised by massively enlarged ovaries and a hyperpermeable/procoagulant state, giving rise to diverse symptoms such as abdominal pain, nausea, ascites, hypovolemia and thromboembolism.

  4. 4. Endocrine and therapeutic aspects of infertile women with the polycystic ovary syndrome

    Författare :Margareta Fridström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; cost-effectiveness; FSH threshold; glucocorticoids; granulosa cells; infertility; in vitro fertilisation; obesity; ovulation induction; polycystic ovary syndrome; pregnancy complications;

    Sammanfattning : Fertility treatment with gonadotrophins in infertile clomiphene resistant women with the polycystic ovary syndrome (PCOS) is troublesome with an unpredictive ovarian response. The purpose of this study was to elucidate aspects of ovarian sensitivity and to evaluate treatment efficiency and costs of ovulation induction (OI) and in vitro fertilisation (IVF), as well as pregnancy outcome after infertility treatment in patients with PCOS.

  5. 5. Genetic studies in early embryos with emphasis on preimplantation genetic diagnosis

    Författare :Erik Iwarsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; chromosomal abnormality 1 embryo fluorescent in situ hybridisation FISH 1 in vitro fertilisation IVF 1 preimplantation genetic diagnosis PGD ;

    Sammanfattning : It has been estimated that as much as 70-80% of all human conceptions do not develop to term. A majority of clinically recognisable pregnancies, which are miscarried, contain chromosome abnormalities. However, data from very early embryo development are difficult to obtain. LÄS MER
