    Sammanfattning : Internal fertilization usually implies that a spermatozoon, with intact attributes for zygote formation, passes all hurdles during its transport through the female genitalia and reaches the oocyte. During this journey, millions to billions of other spermatozoa perish. LÄS MER

  2. 2. GABA and human spermatozoa : characterization and regulation of GABA transport proteins

    Detta är en avhandling från Stockholm : Karolinska Institutet, false

    Författare :Arthur Aanesen; Karolinska Institutet.; Karolinska Institutet.; [1998]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; GABA; spermatozoa; GABA transport; acrosome reaction; sperm motility; progesterone; protein kinase C; GAT-1; GAT-2; GAT-3; BGT-1;

    Sammanfattning : The present project aimed at investigating the interaction between GABA and human spermatozoa under in vitro conditions. Our initial hypothesis was that human spermatozoa had specific binding proteins for GABA and that the binding of GABA to such binding sites could affect sperm fimction. LÄS MER

  3. 3. Perspectives on the Biological Role of Human Prostasomes

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Lena Carlsson; Uppsala universitet.; [2001]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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;

    Sammanfattning : 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.
