2. 1. Ovarian Reserve and Assisted Reproduction

   Author : Thomas Brodin; Jan Holte; Matts Olovsson; Lars Berglund; Juha Tapanainen; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; AFC; AMH; anti-Müllerian hormone; antral follicle count; follicle-stimulating hormone; FSH; ICSI; infertility; intracytoplasmic sperm injection; in vitro fertilization; IVF; LH; live birth; luteinizing hormone; menstrual cycle; menstrual cycle length; ovarian reserve; pregnancy; reproductive endocrinology; reproductive technology; Medicinsk vetenskap; Medical Science;

   Abstract : Treatment success in IVF-ICSI is mainly limited by female age, but differences in ovarian reserve (OR; the remaining pool of oocytes and their quality) between individuals modify treatment prerequisites among women of similar age. OR may be assessed by OR tests (ORTs). READ MORE

4. 2. Chemotactic factors in the human follicle at ovulation

   Author : Eva Runesson; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chemokine; follicle; gonadotropin; human; ovary; ovulation;

   Abstract : Ovulation is initiated by the midcycle gonadotropin surge, which leads to a controlled degradation of the follicle wall ending in follicular rupture and oocyte extrusion. The gonadotropins triggers several biochemical and biophysical changes such as vascular alterations, increased proteolytic enzyme activity and leukocyte extravasation, within the preovulatory follicle.

5. 3. 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.

6. 4. 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

7. 5. Effects of Oral Contraceptives on Endogenous Hormones, Body Constitution, and Breast Epithelium in Healthy, Young Women

   Author : Helena Jernström; Bröstcancer-genetik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cytology; ovarian; breast cancer; proliferation; breast size; progesterone; estradiol; testosterone; luteinizing hormone; follicle stimulating hormone; sexual hormone binding globulin; insulin-like growth-factor-1; prolactin; Oral contraceptives; nulliparous women; oncology; cancerology; Cytologi; onkologi; cancer; Endocrinology; secreting systems; diabetology; Endokrinologi; sekretion; diabetologi;

   Abstract : This thesis concerns the effects of low-dose oral contraceptives (OCs) on endogenous hormones, insulin-like growth-factor-1 (IGF-1), sexual hormone binding globulin (SHBG), and body constitution in two groups of healthy women aged 19­25 who had never been pregnant. Prolactin concentrations were elevated in a subgroup of present and former users. READ MORE
