    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. 32. Immune regulation during pregnancy in relation to allergy and in women undergoing in vitro fertilization

    Författare :Marie Persson; Maria Jenmalm; Göran Berg; Christina Ekerfelt; Lucia Mincheva-Nilsson; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : During pregnancy, the fetus expresses both maternal and paternal antigens. To the mother, the paternal antigens are foreign, providing her immune system with an interesting challenge. The fact that the fetus is not normally attacked and rejected implies that mechanisms of tolerance must exist. LÄS MER

  4. 33. Culture and vitrification of human preembryos

    Författare :Fredwell Hambiliki; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Despite improvements in stimulation protocols, culture media formulations and laboratory protocols, the success rates in human IVF remain disappointingly low. The ability to successfully cryopreserve supernumerary embryos in a given IVF cycle without losing significant embryo viability is essential to maximize the cumulative benefit of a given treatment cycle.

  5. 34. Stress, depression, and other psychiatric disorders : an epidemiological approach to studying the causes and consequences for in vitro fertilization outcome and polycystic ovary syndrome

    Författare :Carolyn E Cesta; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Reproductive epidemiology, psychiatric epidemiology, and pharmacoepidemiology come together in this thesis which is comprised of four studies and divided into two parts. Part 1 examines the impact of stress and depression on the outcomes of infertility treatment in women undergoing in vitro fertilization (IVF). LÄS MER

  7. 35. Human gonadotrophins for ovarian stimulation in infertility treatment

    Författare :Jonas Harlin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Infertility problems are present in 10 to 15 % of couples of fertile age. Ovulatory dysfunction, as a single cause, can be successfully treated and in-vitro fertilisation (IVF) can help a considerable number of couples, also when male problems are present. LÄS MER
