1. Microfluidic sorting of sperm for assisted reproduction - An evaluation of ZyMōt multi sperm separation device
Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskapSammanfattning : 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. LÄS MER
2. Use of a Sperm-Hyaluronan Binding Assay for evaluation of sperm quality in dromedary camels
Master-uppsats, SLU/Dept. of Clinical SciencesSammanfattning : 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. LÄS MER
3. Effects of melatonin and Single Layer Centrifugation on cryosurvival of ram semen samples
Master-uppsats, SLU/Dept. of Clinical SciencesSammanfattning : 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.

4. The influence of antimicrobial agents on the development of antibiotic resistance in the vaginal bacterial flora of artificially inseminated mares : a study on mares in a stud environment
Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Clinical SciencesSammanfattning : In Sweden and in many other countries, artificial insemination (AI) is frequently used in horse breeding. The technology makes it possible to use genetic material from horses in different geographical locations in an effective way, minimizing the risk of infection or even injury to both horses and stud personnel.

5. Säkerhet och effektivitet av hormonella preventivmedel för män
Kandidat-uppsats, Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)Sammanfattning : Bakgrund: Hormonella preventiva läkemedel för män är idag inte tillgängliga på marknaden, de enda tillgängliga preventivmedlen för manligt bruk är i dagsläget kondom och vasektomi som båda är icke-hormonella. Utbudet till kvinnor är desto fler, det första hormonella preventivmedlet till kvinnor godkändes redan på 1960-talet. LÄS MER
