  2. 16. Reproductive function in young Swedish men - Time trend, prenatal and adult exposure to smoking and phthalates

    Author : Jonatan Axelsson; Malmö Reproduktionsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Semen analysis; maternal exposure; paternal exposure; smoking; phthalate;

    Abstract : A decrease in male reproductive function, including sperm counts, during the second half of the 20th century, has been postulated. During this period, testicular cancer has increased several-fold. Environmental and lifestyle-related factors have been proposed as explanations for a possible negative trend in male reproductive function. READ MORE

  4. 17. Anti-Müllerian hormone and fertility in male patients with chronic kidney disease

    Author : Dag Eckersten; Internmedicin - epidemiologi; []
    Keywords : ;

    Abstract : AbstractBoth men and women with end stage renal disease (ESRD) often suffer from infertility. The reason for this is multifactorial and includes sexual dysfunction, psychological factors and hormonal disturbances. The hypothalamic-pituitary gonadal axis is altered already at moderate reduction in kidney function. READ MORE

  5. 18. Chlamydia trachomatis as a risk factor for infertility in women and men, and ovarian tumor development

    Author : Annika Idahl; Ulrika Ottander; Jan I Olofsson; Eva Lundin; Fredrik Elgh; Jorma Paavonen; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antibodies; borderline tumors; Chlamydia trachomatis; cHSP60; DNA; infertility; ovarian cancer; pregnancy rate; RNA; semen characteristics; Obstetrics and gynaecology; Obstetrik och gynekologi; obstetrik och gynekologi; Obstetrics and Gynaecology;

    Abstract : Background: Chlamydia trachomatis in women is a risk factor for tubal factor infertility and extra uterine pregnancies, but the impact of a C. trachomatis infection on male fertility is unclear. It is also hypothesized that persistent infection with C. trachomatis, or other microorganisms, might initiate/promote ovarian tumor development. READ MORE

  6. 19. 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. 20. Reproductive toxicology of endocrine disruptors : effects of cadmium, phthalates and phytoestrogens on testicular steroidogenesis

    Author : David Gunnarsson; Gunnar Selstam; Gunnar Nordberg; Per Leffler; Henrik Leffers; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Endocrine disruptors; reproductive toxicology; cadmium; phthalates; DEHP; MEHP; phytoestrogens; steroidogenesis; testosterone; Leydig cell; Molecular biology; Molekylärbiologi;

    Abstract : A number of investigations during the last two decades describe adverse trends in male reproductive health, which have been proposed to be caused by environmental factors with endocrine disrupting properties. In contrast to many other toxicants, endocrine disruptors often do not show linear dose-response relationships typical of those found in traditional toxicological studies. READ MORE
