1. 36. Female stress incontinence and uterovaginal prolapse : collagen turnover and hormone sensitivity in urogenital tissue

   Författare :Lena Edwall; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Stress incontinence; urogenital tissue; collagen turnover markers; estradiol- 17beta; estrone; testosterone; uterovaginal prolapse; menopause;

   Sammanfattning : Background: Prevalence of both stress urinary incontinence (SUI) and uterovaginal prolapse (UP) is high and rising with age. Risk factors include multiparity, obesity, chronic obstructive lung disease and previous gynecological surgery. The underlying pathology is still unknown but may include defective connective tissue.

   Sammanfattning : Premenstrual depressive symptoms and mood swings affect 3-8% of women in fertile age. The female hormones are believed to be the cause. Progesterone is well studied, but estrogen is not, and either are other causes such as intimate partner violence and chronic stress. LÄS MER

   Sammanfattning : Ovarian steroid hormones are neuroactive steroids with widespread actions in the brain, and are thus able to influence mood, behavior and cognition. In this thesis the effects of progesterone withdrawal and the direct effects of the progesterone metabolite allopregnanolone are evaluated. LÄS MER
