| description |
At the forensic analysis level regarding the collected samples on sex crimes when semen is the body fluid which is evidence in a criminal act since one of its components are sperm and these cells are specific and retained for a longer perior of time because they contain DNA and 200 to 400 million sperms are found in a normal ejaculate (1); for this reason, these cells are an important tool in the administration of justice. Although researchers found no relationship between sex-related crimes and animals, it is very important to build a difference between the morphological characteristics between human sperm and animal sperm daily connected to the man.The goal of this document is to determine the differences between human and animal sperm by using the christmas tree coloring method as well as the microscopic observation. A human semen sample was collected from some domestic animals ejaculation like bull, hamster, horse, dog, pig and cat by an extended process which was developed, stained and analyzed under the light microscope, finding some significant differences in the studied species sperm and in which the shape, size and color were outstanding allowing to identify the characteristics of each species. The most similar characteristics were found between the man´s sperm and the dog´s sperm. The difference between man´s sperm and the animal´s one is very important at the time of solving forensic cases. The morphometric study revealed some clear differences between the analyzed sperm which will be a very important tool when seeking a given sample. |

Razón por lo cual son una herramienta importante en la administración de justicia. Aunque no es frecuente encontrar delitos sexuales asociados con animales, es importante diferenciar las características morfológicas entre el espermatozoide humano y el de otro tipo, de animales, que se relacionan en la vida cotidiana con el ser humano. El estudio pretendió determinar diferencias entre los espermatozoides humanos y animales por medio del método de coloración árbol de navidad y observación microscópica. Se recolectó semen humano y los eyaculados de animales domésticos como: toro, hámster, caballo, perro, cerdo y gato. Luego se realizaron extendidos, los cuales fueron teñidos y analizados en microscopio óptico, encontrando diferencias significativas en los espermatozoides de las especies estudiadas dentro de las que se destacaron: forma, tamaño y color, las cuales permitieron individualizar características propias de cada especie. Se visualizó que el espermatozoide con mayor similitud al de humano es el del perro. La diferenciación de espermatozoides humanos con animales es relevante en la resolución de casos forenses. El estudio morfométrico reveló diferencias evidentes en los espermatozoides analizados, lo cual será una herramienta importante en el momento de su hallazgo en una muestra determinada.application/pdfspaUniversidad Cooperativa de Colombia / Instituto Nacional de Medicina Legal y Ciencias Forenseshttps://revistas.ucc.edu.co/index.php/ml/article/view/1388/1467Derechos de autor 2016 Colombia Forenseinfo:eu-repo/semantics/openAccesshttp://purl.org/coar/access_right/c_abf2Colombia Forense; Vol. 1 No. 2; 29-33Colombia Forense; Vol. 1 Núm. 2; 29-33Colombia Forense; v. 1 n. 2; 29-332145-96492145-0684sex offensesspermatozoamorphologyasalto sexualespermatozoidesmorfologíaMorphometric comparison of human died spermatozoa and pets, dyed with the color of christmas treeComparación morfométrica de espermatozoides humanos y de animales domésticos, teñidos con la coloración árbol de navidadArtículohttp://purl.org/coar/resource_type/c_6501http://purl.org/coar/resource_type/c_2df8fbb1http://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articlehttp://purl.org/redcol/resource_type/ARTinfo:eu-repo/semantics/publishedVersionPublication20.500.12494/44323oai:repository.ucc.edu.co:20.500.12494/443232024-07-16 13:24:12.506metadata.onlyhttps://repository.ucc.edu.coRepositorio Institucional Universidad Cooperativa de Colombiabdigital@metabiblioteca.com |
