  2. 11. Acupuncture in reproductive medicine. Applications in human assisted reproduction and aspects of clinical and experimental neuroendocrinology

    Author : Elisabet Stener-Victorin; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; electro-acupuncture; blood flow impedance; circulation; uterine artery; in-vitro fertilization; oocyte aspiration; polycystic ovary syndrome; experimentally induced PCO; anovulation; gonadotropins; steroids; neuropeptides; b-endorphin; nerve growth factor; corticotropin-releasing factor.;

    Abstract : The use of acupuncture in the area of reproductive medicine is relatively new, and it has been rather poorly investigated in the past. When muscle afferents are stimulated by acupuncture in somatic segments related to the innervation of the ovaries and the uterus, functional changes occur in the neural substrate that may influence reproductive function and result in peripheral, segmental and central effects.

    Author : Eugenia Colón; Karolinska Institutet; Karolinska Institutet; []
    Keywords : IGFs; steroidogenesis; Leydig cells; steroidogenic acute regulatory protein StAR ; insulin; IGFBP-3; IGFBP-2 and steroidogenic enzymes;

    Abstract : The primary function of testicular Leydig cells is the production of androgens that promote sexual differentiation in the fetus, secondary sexual maturation at the. time of puberty, and spermatogenesis in the adult. READ MORE

  5. 13. Hormonal and metabolic effects of diet and physical exercise in overweight/obese women with polycystic ovary syndrome

    Author : Åsa Nybacka; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: Overweight/obese women with polycystic ovary syndrome (PCOS) often have hormonal problems characterized by irregular menses and decreased fertility.

  6. 14. Feedback control of reproduction in Atlantic salmon, Salmo salar, male parr

    Author : Efthimia Antonopoulou; Sylvie Dufour; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; zoologi; Zoology;

    Abstract : In fish, as in other vertebrates, the gonads are stimulated by two pituitary gonadotropic hormones, follicle stimulating hormone (FSH) and luteinizing hormone (LH). LH and FSH secretion are regulated by the gonadal steroids acting either directly on the pituitary or indirectly via the hypothalamus. READ MORE

  7. 15. The role of leptin in zebrafish (Danio rerio) : Novel insights into appetite regulation and reproduction

    Author : Emmanouil Tsakoumis; Monika Schmitz; Tatjana Haitina; Åsa Wallén-Mackenzie; Ana Gómez Peris; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; zebrafish; leptin; appetite; GRN; brain; reproduction; oocyte maturation; ovulation; Biology with specialization in Comparative Physiology; Biologi med inriktning mot jämförande fysiologi;

    Abstract : The hormone leptin is a peripheral metabolic signal and an important regulator of energy balance. In mammals, leptin acts on the appetite centers in the hypothalamus, causing anorexigenic functions by inhibiting food intake. It is also considered as a link between the nutritional status and the endocrine reproductive axis. READ MORE
