2. 1. OVULATION: Intra-ovarian mechanisms

   Author : Farnosh Sørensen Zakerkish; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ovulation; Human;

   Abstract : Background: Ovulation is the central biological process involved in the menstrual cycle of women. Specifically, ovulation involves the tissue remodelling of the preovulatory follicle to achieve the rupture of the exterior follicle wall with the extrusion of the oocyte. 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. Molecular mechanisms of ovarian follicular development and early embryogenesis

   Author : Nagaraju Gorre; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; ovary; primordial follicles; Embryogenesis; PI3K-mTORC1 signaling;

   Abstract : In the mammalian ovary, the dormant primordial follicles are the source of developing follicles and fertilizable ova for the entire reproductive life. In addition, the duration of fertility of a female is determined by the initial size of her pool of primordial follicles and by the rate of its activation and depletion. READ MORE

6. 4. Three-dimensional ultrasound studies of normal and abnormal ovaries

   Author : Ligita Jokubkiene; gynekologisk och prenatal ultraljudsdiagnostik Obstetrisk; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ovary; ovarian follicle; ovarian neoplasms; ultrasonography; three-dimensional imaging; Doppler ultrasound imaging; vascular morphology;

   Abstract : The aims of this work were: 1) to estimate the number of follicles, ovarian volume and power Doppler vascular indices and their changes with age using three-dimensional (3D) transvaginal grey-scale and power Doppler ultrasound in asymptomatic women of fertile age either with natural menstrual cycles or using combined oral contraceptives, and 2) to determine whether tumour vascularity, assessed by 3D power Doppler ultrasound, can help discriminate between benign and malignant ovarian tumours. A group of 303 gynaecologically asymptomatic women, aged 20–39 years with normal menstrual cycles (NMC) and another group of 213 women aged 20–39 years using combined oral contraceptives (COC) were examined using two-dimensional (2D) and 3D transvaginal ultrasound once between cycle day 4 and 8.

7. 5. Polycystic ovary syndrome - morphologic and dynamic evaluation by magnetic resonance imaging

   Author : Henrik Leonhardt; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; polycystic ovary syndrome; PCOS; magnetic resonance imaging; MRI; ultrasonography; three-dimensional imaging; adrenal hyperplasia; body composition; uterine morphology; uterine peristalsis; ovarian morphology; ovarian perfusion; antral follicle count; AMH; diagnostic accuracy;

   Abstract : Polycystic ovary syndrome (PCOS) is a complex endocrine disorder, affecting up to 15% of women of reproductive age. The syndrome is characterized by oligo-anovulation, hyperandrogenism and polycystic ovaries. What constitutes the best definition of PCOS is still a matter of debate. READ MORE
