12. Growth factors in spermatogenesis
Abstract : The aim of this study was to increase the knowledge of die effects of locally produced growth factors and hormones on germ cell proliferation in rat testis in vitro. Since impaired sperm production and function accounts for half the cases of infertility, it is important to understand the physiological actions in germ cell development. READ MORE

14. Brain-sparing Circulation in Growth-restricted Human Fetuses
Abstract : The aim of the studies was to explore fetal circulatory changes relative to development of brain-sparing flow (BSF) in growth-restricted fetuses exposed to acute hypoxic stress, as provoked by uterine contractions during an oxytocin challenge test (OCT).(1) In fetuses with a normal cerebral circulation during basal conditions, signs of an acute hyperperfusion in both the arterial and venous cerebral vascular systems were demonstrated in response to acute hypoxic stress; (2) Fetuses with an already established BSF showed no further ability of brain-sparing during acute hypoxic stress; (3) In venous cerebral vessels of fetuses with established BSF, the flow responses to hypoxic stress were equivocal, indicating different reactions in areas drained by different veins, or a deranged physiological vascular response; (4) Blood flow changes occurred synchronized in the middle and anterior cerebral arteries when fetuses with an intact cerebral circulation were exposed to hypoxic stress; (5) When fetuses with an established BSF showed no further changes in the middle cerebral artery, no changes were found in the anterior cerebral artery either.

15. Cardiovascular function in normal pregnancy and fetal growth
Abstract : Background: Pregnancy is a challenge to a woman’s cardiovascular system, and extensive haemodynamic changes are required for optimal utero-placental circulation and fetal growth. The aim of this thesis was firstly to examine different aspects of vascular function in the same women longitudinally during normal pregnancy, and secondly to explore whether there is an association between maternal cardiovascular function, placental function, and fetal growth.
