2. 1. 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.

4. 2. Adrenoceptors and nerve growth factor. Effects of electro-acupuncture and physical exercise in rats with steroid-induced polycystic ovaries

   Author : Luigi Manni; Göteborgs universitet; []
   Keywords : ;

   Abstract : Polycystic ovary syndrome (PCOS) is complex endocrine and metabolic disorder associated with ovulatory dysfunction, follicular cyst and hyperandrogenism. The abnormalities detected in PCOS have been attributed to primary defects in the hypothalamic-pituitary unit, the ovarian microenvironment, the adrenal gland, and the insulin/insulin-like growth factor (IGF)-1 metabolic regulatory system.

   Abstract : The aim of the present thesis was to investigate some factors underlying the metabolic, anthropometric, and endocrine abnormalities of women with the polycystic ovary syndrome (PCOS).An iv insulin tolerance test (0.15 IU bolus) showed substantially preserved glucose counterregulation in women with PCOS (n=18).

6. 4. Experimental studies on ovarian cryopreservation and transplantation

   Keywords : cryopreservation; ovary; transplantation; animal models;

   Abstract : Around 8% of all cancer victims are below 40 years of age and the survival after cancer treatment during childhood and reproductive years has increased considerably to be around 80% today. The clinical field of fertility preservation has emerged to enable cancer patients that are treated with potentially gonadotoxic chemotherapy-radiotherapy during childhood or reproductive ages, to preserve their fertility.

7. 5. Modeling human germ cell development with pluripotent stem cells and characterizing the putative oogonial stem cells

   Author : Sarita Panula; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : The current understanding of human germ cell development is limited and is at most parts extrapolated from studies of mice or other model organisms. Particularly, the specification events of human germ cell lineage are largely unknown, which is at least in part due to inaccessibility of early stages of human development. READ MORE
