  1. 1. 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
