1. 1. Microfluidic sorting of sperm for assisted reproduction - An evaluation of ZyMōt multi sperm separation device

   University essay from Göteborgs universitet / Instiutionen för biologi och miljövetenskap

   Author : Emma Olofsson; [2023-06-22]
   Keywords : Assisted reproduction technologies Spermatozoa DNA fragmentation Density-gra- dient centrifugation Microfluidics ZyMōt Multi;

   Abstract : Infertility is a worldwide problem and the main reason for the use of assisted reproductive technol- ogy (ART). In-vitro fertilization (IVF) is one ART treatment normally used, where the fertilization of oocytes occurs in vitro. READ MORE

3. 2. En undersökning av genetisk variation associerad med spermiedefekter hos berner sennen

   University essay from SLU/Dept. of Clinical Sciences

   Author : Anna Snell; [2022]
   Keywords : Berner sennen; fruktsamhet; spermakvalitet; spermiemorfologi; nedärvning; genetiska defekter;

   Abstract : Hos hundrasen berner sennen har rasklubben de senaste åren observerat en ökning av fruktsamhetsrelaterade problem, såsom att tikar inte blir dräktiga, minskat antal valpar i kullarna och förlossningsproblem. Dräktighetsprocenten hos berner sennen ligger idag 10–20 % lägre än hos andra raser. READ MORE

4. 3. 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

5. 4. Effects of melatonin and Single Layer Centrifugation on cryosurvival of ram semen samples

   University essay from SLU/Dept. of Clinical Sciences

   Author : Lea Enenkelová; [2021]
   Keywords : sheep reproduction; Jezersko-Solčava sheep breed; colloid centrifugation; melatonin;

   Abstract : The composition of the ram sperm membrane renders it vulnerable to injury during cryopreservation. Production of reactive oxygen species, which are by-products of metabolism, increases during freezing and thawing, causing damage to sperm membranes and acrosomes as well as affecting mitochondrial activity.

6. 5. 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
