1. Acute Testosterone Changes in Response to Machines and Free Weights ResistanceExercise: A Systematic Review
Magister-uppsats,Sammanfattning : Introduction: Testosterone is an anabolic steroid that plays key roles in growing muscles, enhancing physical performance and appearance, maintaining bone density, sex drive and sperm production. It is highly sought-after by athletes for its ability to accelerate muscle growth. LÄS MER
2. Investigation of the interaction of A-MYB and TCFL5 on pachytene PIWI-interacting RNA genes in two sub-species of mice, mus musculus musculus and mus musculus castaneus
Master-uppsats, Högskolan i Skövde/Institutionen för biovetenskapSammanfattning : Spermatogenesis is a complex process that involves the production of sperm cells from germ cells in order to transmit genetic information to progeny. The PIWI-interacting RNA (piRNA) is a non-coding small silencing RNA that guides the PIWI protein to silence target transposon transcripts to regulate the production of germ cells. LÄS MER
3. Single-cell transcriptomic and antibody-based proteomic analysis of Sertoli cell-specific markers in human testis
Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskapSammanfattning : The testis is a complex organ responsible for sperm production and hormone synthesis. Spermatogenesis, the process of sperm formation, occurs in the seminiferous tubules and involves the coordinated development of germ cells with the support of Sertoli cells. LÄS MER
4. 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.

5. AMH i serum och seminalplasma hos hund : association till spermakvalitet
Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Clinical SciencesSammanfattning : 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. LÄS MER
