1. 1. Elective single embryo transfer

   Författare :Ann Thurin-Kjellberg; Göteborgs universitet; []
   Nyckelord :In vitro fertilization; elective single embryo transfer; multiple pregnancies; randomized; controlled trial; prediction of IVF outcome; embryo selection; cost-effectiveness analysis;

   Sammanfattning : The aim of the study was to evaluate if the elective single embryo transfer (eSET) strategy couldmaintain delivery rates, with at least one live born child, and at the same time decrease the rate ofmultiple births. A cost-effectiveness analysis was also performed between the elective single embryotransfer (SET) (1+1) and double embryo transfer (DET) (2+0) strategies. LÄS MER

3. 2. Developmental disturbances of the embryo in diabetic pregnancy

   Författare :Parri Wentzel; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; diabetes; pregnancy; embryo; malformation; glucose; ROS; SOD; NAC; prosta- glandin; COX; COX inhibitor; gene expression; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

   Sammanfattning : Maternal diabetes during pregnancy constitutes an increased risk for congenital malformation in the offspring. Previous studies have suggested that diabetic embryopathy is associated with an excess of reactive oxygen species (ROS) as well as with a disturbance of prostaglandin (PG) metabolism. LÄS MER

4. 3. Prediction of embryo viability by morphology and metabolomic profiling

   Författare :Aisling Ahlström; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NIR spectroscopy; morphology; blastocyst; IVF; trophectoderm; live birth; metabolomic; embryo;

   Sammanfattning : Abstract The ultimate challenge for all in vitro fertilisation (IVF) clinics is to develop the ability to select for transfer the best single embryo first, from the patient’s cohort of embryos, thereby maximising the chance of pregnancy while the incidence of multiple pregnancies is kept to a minimum and fewer transfer cycles are required. This ambition has driven extensive research and development into methods that can be used to predict embryo viability. LÄS MER

5. 4. The Histidine-rich Glycoprotein in Reproduction

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

   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

7. 5. Transcriptional regulation of the human pre-implantation embryo

   Författare :Elo Madissoon; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : 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. LÄS MER
