  4. 2. Perspectives on the Biological Role of Human Prostasomes

    Author : Lena Carlsson; Outi Hovatta; Uppsala universitet; []
    Keywords : Medical sciences; Prostasomes; cryopreservation; human spermatozoa; sperm motility; anti- prostasome antibodies; PC-3 cells; Bacillus megaterium; antibacterial; antisperm antibodies; complement activation; sperm agglutination; infertility; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Chemistry; klinisk kemi;

    Abstract : Prostasomes are extracellularly occurring organelles which are secreted in human semen by the prostate gland. Prostasomes have several known biological activities, but their physiological function is still unclear. In this thesis some new aspects were studied on the biological role of the prostasomes.

  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. 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

  7. 5. Studies on in vitro fertilised human preembryos. Morphological and chromosomal aspects

    Author : Thorir Hardarson; Göteborgs universitet; []
    Keywords : IVF; oocyte; embryo; blastocyst; human; FISH; aneuploidy;

    Abstract : The success rate of in vitro fertilisation (IVF) has gradually increased due to basic research in preembryonic biology and the introduction of new methods, both technical and medical. However, further research is needed to establish which preembryos are developmentally most competent in order to be able to maintain the pregnancy rate while only a single preembryo is being transferred.
