  2. 1. EXPOSURE TO PERSISTENT ORGANOCHLORINE POLLUTANTS AND MALE SEMEN FUNCTION

    Author : Anna Rignell-Hydbom; Avdelningen för arbets- och miljömedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Miljömedicin; Environmental health; epididymal and accessory sex gland function; Y:X sperm chromosome ratio; sperm chromation integrity; sperm concentration; sperm motility; persistent organochlorine poluutants;

    Abstract : Persistent organochlorine pollutants (POPs), such as polychlorinated biphenyls (PCB) and the insecticide dichloro-diphenyl-dichloro-ethylene (DDT) have been released into the environment mainly since the second World War. POPs accumulate especially in highly ranked predators of the aquatic food chain. READ MORE

  4. 2. The impact of genetic, environmental and life-style factors on male reproductive function

    Author : Jonas Richthoff; Malmö Reproduktionsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; male reproductive function; testicular cancer; smoking; Medicin människa och djur ; Medicine human and vertebrates ; cryptorchidism; sperm concentration;

    Abstract : Recent studies have indicated a decline in sperm number in the western world during the past 50 years, sperm concentration changing from 113 to 66 millions per mL. Furthermore, significant geographical differences in male reproductive function have been observed. READ MORE

  5. 3. Zinc and human sperm chromatin

    Author : Svante Kjellberg; Björn Afzelius; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : X-rny microanalysis, Sephadex® chromatography of seminal plasma and exposure of spermatozoa to sodium dodecyl sulphate (SDS), were methods used to study the zinc content of sperm chromatin, the nature of the zinc binding ligands present in seminal plasma and the stability of the sperm chromatin in whole semen samples from fertile and infertile men. Split ejaculates were used to study the same variables in different fractions of the same ejaculate. READ MORE

  6. 4. The Kallikrein-Related Peptidases hK2 and PSA with Emphasis on Genetic Variation, Secretion, and Sperm Motility

    Author : Charlotta Sävblom; Malmö Klinisk kemi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; human glandular kallikrein 2; KLK3; hk2; prostate-specific antigen; PSA; sperm motility; seminal plasma; androgen receptor; SNP; CAG; KLK2;

    Abstract : Prostate-specific antigen (PSA) and human glandular kallikrein 2 (hK2) are secreted by the prostate into seminal plasma and through leakage into blood. This leakage increases rapidly in prostate disease, and PSA is used worldwide as a marker of prostate cancer. READ MORE

  7. 5. Studies on genetic aberrations as possible predictors of the outcome of assisted reproduction

    Author : Mona Bungum; Malmö Reproduktionsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; assisted reproduction; IUI; Sperm chromatin; ICSI; intra-individual variation; fertilisation failure genetic aberration; Protein C inhibitor gene; sperm DNA damage SCSA; IVF;

    Abstract : Traditionally, diagnosis of male infertility has relied upon microscopic assessment of semen. The normality criteria set by the World Health Organization (WHO) in regard to sperm concentration, motility and morphology are, however, poor predictors of fertility. READ MORE
