  1. 1. 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.

    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

  3. 3. Matrix metalloproteinase-26 (MMP-26) and Tissue inhibitor of metalloproteinases-4 (TIMP-4) in normal, hyperplastic, and malignant endometrium

    Author : Radovan Pilka; Lund Obstetrik och gynekologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cancer; Obstetrics; gynaecology; Cytologi; onkologi; cancerology; secretion; Biology; Biologi; Cytology; oncology; implantation; human; endometrium; mRNA; MMP-26; TIMP-4; reproduktion; andrologi; gynekologi; Obstetrik; sexuality; reproduction; sexualitet; andrology;

    Abstract : The aim of the thesis was to study matrix metalloproteinase-26 (MMP-26) and tissue inhibitor of metalloproteinases-4 (TIMP-4) in normal, hyperplastic, and malignant endometrium. Most importantnly, both these molecules may be ivolved in the implantation process. Trophoblast tissue from human as well as mouse embryos produces pro-MMP-9. READ MORE

  4. 4. Transcriptional regulation of the human pre-implantation embryo

    Author : Elo Madissoon; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Millions of couples worldwide have difficulties in conceiving a child. These couples, affected by infertility, suffer from symptoms of stress. The causes of infertility are largely unknown and current available treatment, in vitro fertilization has moderate success rates. READ MORE

  5. 5. Human endometrial receptivity and embryo-endometrium interactions

    Author : Signe Altmäe; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Infertility is an increasing medical and social problem affecting more than 10% of couples worldwide. Many underlying causes of human infertility have been overcome by assisted reproductive techniques; nevertheless, the implantation process remains one of the rate-limiting step as regards the success of the treatment.
