2. 1. The Histidine-rich Glycoprotein in Reproduction

   Author : Karin E Lindgren; Inger Sundström-Poromaa; Helena Åkerud; Eva Wiberg-Itzel; Lalit Kumar Parameswaran Grace; Uppsala universitet; []

   Abstract : 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. READ MORE

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

   Author : Anders Enskog; Göteborgs universitet; []
   Keywords : 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;

   Abstract : 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.

5. 3. Studies on in vitro fertilised human preembryos. Morphological and chromosomal aspects

   Author : Thorir Hardarson; Göteborgs universitet; []
   Keywords : IVF; oocyte; embryo; blastocyst; human; FISH; aneuploidy;

   Abstract : The success rate of in vitro fertilisation (IVF) has gradually increased due to basic research in preembryonic biology and the introduction of new methods, both technical and medical. However, further research is needed to establish which preembryos are developmentally most competent in order to be able to maintain the pregnancy rate while only a single preembryo is being transferred.

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

   Author : Erik Iwarsson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : chromosomal abnormality 1 embryo fluorescent in situ hybridisation FISH 1 in vitro fertilisation IVF 1 preimplantation genetic diagnosis PGD ;

   Abstract : 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. READ MORE

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

   Author : Jonas Harlin; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : 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. READ MORE
