  2. 1. The impact of gonadotropin receptor polymorphisms on human reproductive function

    Author : Ida Lindgren; Malmö Molekylärgenetisk reproduktionsmedicin; []
    Keywords : FSHR; LHCGR; single-nucleotide polymorphism SNP ; in vitro fertilization IVF ; reproduction; Infertility; male fertility; female fertility;

    Abstract : To date, approximately 15% of all couples worldwide suffer from infertility. The management include controlledovarian hyper-stimulation of the women with follicle-stimulating hormone (FSH) and semen analysis of the men,prior to in vitro fertilization (IVF) and transfer of the fertilized embryo to the uterine cavity.

  4. 2. Male and female selective mechanisms, reproductive success and gene flow

    Author : Samuel Kiboi; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Växtekologi; Plant ecology; Cucumis sativus.; genetic marker; gene flow; reproduction; embryo abortion; resistance; maternal selection; sexual selection; pollen competition; selection;

    Abstract : In this thesis, I have studied male and female selective mechanisms that can affect plant reproductive success and gene flow. I have focussed on sexually selected traits, mainly pollen competition and maternal sorting mechanisms, for example through non-random ovule abortion. READ MORE

  5. 3. Birth Characteristics’ Impacton Future Reproduction and Morbidity Among Twins an dSingletons

    Author : Marie Bladh; Gunilla Sydsjö; Ann Josefsson; John Carstensen; Orvar Finnström; Karin Pettersson; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Twin; singleton; preterm birth; SGA; reproduction; hospitalization; siblings;

    Abstract : Globally, in both developed and developing countries, the twinning rates have increased since the early 70’s. A large proportion of twins are born preterm and/or small-for-gestational-age (SGA) and/or with a low birth weight. READ MORE

  6. 4. The Histidine-rich Glycoprotein in Reproduction

    Author : Karin E Lindgren; Inger Sundström-Poromaa; Helena Åkerud; Eva Wiberg-Itzel; Lalit Kumar Parameswaran Grace; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Angiogenesis; embryo culture medium; embryogenesis; embryonic secretome; endometrium; histidine-rich glycoprotein; human embryo development; human embryo implantation; human endometrial endothelial cells; in vitro fertilisation; infertility; male infertility; proximity extension assay; recurrent miscarriage; single nucleotide polymorphism; sperm quality; time-lapse technique; vascular endothelial growth factor;

    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

  7. 5. Fetal surveillance and outcome in postterm pregnancy

    Author : Margareta Kitlinski; gynekologisk och prenatal ultraljudsdiagnostik Obstetrisk; []

    Abstract : To minimize the risk of short-term and long-term morbidity and mortality among children born postterm, studies were performed to evaluate the fetal surveillance program. (1) Male-fetus pregnancies were at an increased risk... READ MORE
