1. Perspectives on the Biological Role of Human Prostasomes
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.

2. Zinc and human sperm chromatin
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

3. GABA and human spermatozoa : characterization and regulation of GABA transport proteins
Abstract : 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 function. READ MORE

4. Aspects of the regulation of human sperm motility
Abstract : In this thesis I address some of the possible causes for oligozoospermia and low sperm motility, two factors that, singly or in combination, are often seen in cases of male subfertility. In the first study we evaluated the effect on human spermatozoa of the toxicity of compounds present in diesel exhaust. READ MORE

5. Regulation and function of the human fallopian tube
Abstract : The Fallopian tube is essential for human reproduction. Transport of the spermatozoa, the egg, and later the pre-embryo is believed to be aided by muscular contractions in the wall of the Fallopian tube and cilia in the mucosa. READ MORE
