   Keywords : ;

   Abstract : 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. READ MORE

4. 3. The Examination of Alternative Methods for Sperm Cell Lysis and Purification of Sexual Assault Samples

   University essay from Lunds universitet/Teknisk mikrobiologi

   Author : Emilie Boson; [2023]
   Keywords : Differential lysis; Differential extraction; Sexual assault samples; Sperm cells; Forensic; DNA recovery; DNA profiling; DNA purification; Applied microbiology; Technology and Engineering; Biology and Life Sciences;

   Abstract : Forensic sexual assault samples typically contain a mixture of a small quantity of sperm cells and a high quantity of epithelial cells. This relationship complicates the generation of a DNA profile, which prompts the need for differential lysis and extraction of the DNA. READ MORE

5. 4. 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

   University essay from Högskolan i Skövde/Institutionen för biovetenskap

   Author : Most Shova Banu; [2023]
   Keywords : ;

   Abstract : 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. READ MORE

6. 5. Single-cell transcriptomic and antibody-based proteomic analysis of Sertoli cell-specific markers in human testis

   University essay from Högskolan i Skövde/Institutionen för biovetenskap

   Author : Katharina Stanzel; [2023]
   Keywords : ;

   Abstract : 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. READ MORE
