21. Chemotactic factors in the human follicle at ovulation
Sammanfattning : 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.

22. Metabolic and ovarian consequences of perinatal sex steroid programming
Sammanfattning : Endocrine and metabolic disturbances in adulthood may stem from insults such as nutritional and hormonal alterations that occur at critical periods in pre- or postnatal life – a process known as programming. This means that suboptimal conditions in utero and early life may contribute to adult reproductive and metabolic impairments such as type 2 diabetes, insulin resistance, and dyslipidemia. LÄS MER
23. Prophylactic oophorectomy at elective hysterectomy. Effects on sexuality and psychological well-being
Sammanfattning : Background: Ovarian stromal androgens in perimenopausal women are supposed to be of importancefor sexuality and psychological well-being. This notion is based on findings from studies after theadministration of exogenous androgens and retrospectively designed studies on the outcome afteroophorectomy.Aims: 1. LÄS MER
24. The roles of the plasminogen activator and matrix metalloproteinase systems in ovulation and corpus luteum formation
Sammanfattning : Proteases of the plasminogen activator (PA) and the matrix metalloproteinase (MMP) enzyme systems are expressed in the ovulatory follicle and in the developing corpus luteum (CL). However, the functional role of these extracellular degrading protease systems in the ovulatory and CL development processes remains elusive. LÄS MER
25. Granulosa cell apoptosis: Transcriptional regulation by the nuclear progesterone receptor
Sammanfattning : Ovarian follicle atresia caused by granulosa cell apoptosis is a central process in normal female physiology. Progesterone has been reported to be a survival factor in granulosa cells at several developmental stages. LÄS MER
