   Författare :Tiina Murto; Anneli Stavreus-Evers; Agneta Skoog Svanberg; Sven-Eric Olsson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Folate; folic acid supplement; homocysteine; hormones; infertility; IVF; lifestyle factor; MTHFR; predictive value; socioeconomic factor; women; Obstetrik och gynekologi; Obstetrics and Gynaecology;

   Sammanfattning : Various hormones have been studied as regards prediction of pregnancy outcome after infertility treatment, but no ideal candidate has been found. Folate and genetic variations in folate metabolism have also been associated with infertility, but it remains unclear how these factors affect IVF pregnancy outcome. LÄS MER

4. 3. Is it Just the Hormones? : Sex Steroids, Chronic Stress and Violence in Premenstrual Dysphoric Disorder

   Författare :Birgitta Segebladh; Inger Sundström-Poromaa; Marie Bixo; Kristina Gemzell-Danielsson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; premenstrual dysphoric disorder; combined oral contraceptive; GnRH agonist; add-back; estradiol; progesterone; chronic stress; intimate partner violence; depression; anxiety; allopregnanolone; Obstetrics and gynaecology; Obstetrik och gynekologi; Obstetrik och gynekologi; Obstetrics and Gynaecology;

   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

5. 4. Effects of Endocrine Disrupting Chemicals on Human Endometrial Endothelial Cells In Vitro

   Författare :Malin Helmestam; Matts Olovsson; Anneli Stavreus-Evers; Yvonne Lundberg Giwercman; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; endocrine disrupting chemicals; hormones; human endometrial endothelial cells; endometrium; estrogen; progesterone; cadmium; tamoxifen; mifepristone; bisphenol A; angiogenesis; Medicinsk vetenskap; Medical Science;

   Sammanfattning : Evidence from an abundant number of studies suggests that human female reproductive functions have become impaired over the past half century and that there might be a relationship between endocrine disrupting chemicals (EDCs) and reduced fertility. It is, however, not known by what mechanisms EDCs affect different reproductive functions such as endometrial receptivity, embryo implantation and placentation. LÄS MER

7. 5. Effects of some Endocrine Disruptors on Human and Grey Seal Uterine Cells

   Författare :Carolina Bredhult; Matts Olovsson; Britt-Marie Bäcklin; Olle Söder; Uppsala universitet; []
   Nyckelord :Obstetrics and gynaecology; Reproductive toxicology; Baltic grey seal; leiomyoma; myometrial cells; endometrial endothelial cells; hormones; endocrine disruptors; Obstetrik och kvinnosjukdomar;

   Sammanfattning : The effects of environmental contaminants in humans and animals are of great concern. Some contaminants are endocrine disruptors that may interfere with the endogenous hormonal signalling and disturb, for example, reproductive organs and functions. LÄS MER
