  1. 1. Use of a Sperm-Hyaluronan Binding Assay for evaluation of sperm quality in dromedary camels

    University essay from SLU/Dept. of Clinical Sciences

    Author : Anna Kotila-Ioannou; [2022]
    Keywords : Camel Semen; Dromedary camel; Sperm-Hyaluronan Binding Assay; sperm quality analysis;

    Abstract : The objective of this study was to assess the potential of Hyaluronan Binding Assay (HBA) to predict freezability and fertilization capacity of dromedary camel spermatozoa, and to determine if conventional sperm quality parameters and precursor of A-Kinase Anchoring Protein 4 (proAKAP4) values correlate with HBA results. Two semen samples were collected from each of six male camels. READ MORE

  3. 2. AMH i serum och seminalplasma hos hund : association till spermakvalitet

    University essay from SLU/Dept. of Clinical Sciences

    Author : Hannah Olsson; [2021]
    Keywords : AMH; Anti-Müllerskt hormon; hund; berner sennen; spermakvalitet; spermiemotilitet; spermiemorfologi;

    Abstract : Anti-Müllerskt hormon (AMH) har föreslagits som en biomarkör för spermakvalitet, eftersom hormonet produceras av sertolicellen som stödjer spermiernas utveckling. Förändringar i produktion av AMH antas kunna visa på nedsatt funktion i sertolicellen, och på så sätt nedsatt funktion i spermieutvecklingen. READ MORE

  4. 3. Testosterons betydelse för hanhundens fertilitet : kan analys av dess serumkoncentration bidra till fertilitetsdiagnostik?

    University essay from SLU/Dept. of Clinical Sciences

    Author : Stina Wallander; [2021]
    Keywords : testosteron; SHBG; FAI; CPSE; spermier; fertilitet;

    Abstract : Vid avel av hundar är det viktigt med en god fruktsamhet för att få en bred avelsbas. För utvärdering av fertilitet hos handhudar används ofta analys av ejakulat. I denna studie analyseras även serumkoncentration av testosteron för att se om det är en koppling mellan den och spermakvaliteten eller en hanhunds fertilitet. READ MORE

  5. 4. Density of sperm-producing tissue is positively linked to male reproductive success, but not to testes size in the Japanese quail (Coturnix japonica)

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Martine Graf; [2020]
    Keywords : Japanese quail; testes size; seminiferous tubule; sperm concentration; testes asymmetry; artificial selection;

    Abstract : If sexual selection acts in a sex-limited way on a trait that has a shared genetic basis between males and females, the resulting intralocus sexual conflict can have a considerable impact on the opposite sex. A prime example of sexual conflict affecting a shared characteristic would be the reproductive organs in males and females. READ MORE

  6. 5. Genetic diversity status and associations with sperm quality characteristics in farmed Arctic charr (Salvelinus alpinus L.) across Sweden

    University essay from SLU/Dept. of Animal Breeding and Genetics

    Author : Anam Anjum; [2020]
    Keywords : Arctic charr; dd-RADseq; genetic diversity; GWAS; reproductive success;

    Abstract : The national breeding programme of Arctic charr (Salvelinus alpinus L.) has been of fundamental importance for the expansion of Arctic charr farming across Sweden. Selection has been ongoing since 1980s documenting approximately 10% improvement per generation regarding growth related traits. READ MORE
