spelling Physiology of reproduction in applications up to the animal industryFisiología de la reproducción en la altura aplicaciones a la industria animalMonge M., CarlosIn 1931, the author, basing his observations on humans and on animals, stated the problem of fertility in the Andean plateau. Those men who live in the Andes, reproduce the same as those in the sea level. The same can be said of the animals of that region, and particularly those which have been acclimated for 400 years. Concerning animals, newly arrived to high lands, they show a diminution (50 to 60 70) in their fertility. The author describes the possible causes of this phenomenon. He points out the various methods of Electro ejaculation, which permit the obtaining of semen, when desired. He also indicates the occurrence of spermatogenesis in cats and rabbits at 4000 mts. above sea level. The author studies the characteristics of the standard semen of animals (rams ) and gives directive methods of research for verifying his hypothesis. Having once determined the "Standard Semen" of the altitude, the author concludes on the possibilities of improving fertility by selecting acclimatized rams. Disregards the problem of so called "machorras" (infertile ewes ) as he has obtained 86 % of fertility, and makes a comparative study of the races best suited for acclimatization.En 1931, el autor, basando sus observaciones en seres humanos y en animales, planteó el problema de la fertilidad en la meseta andina. Los hombres que viven en los Andes, se reproducen los mismos que en el nivel del mar. Lo mismo puede decirse de los animales de la región, y en particular los que se han aclimatado durante 400 años. En cuanto a los animales, recién llegados a tierras altas, muestran una disminución (del 50 al 60 de 70) en su fertilidad. El autor describe las posibles causas de este fenómeno. Señala los diversos métodos de Electro eyaculación, que permitan la obtención de semen, cuando se desee. También indica la ocurrencia de la espermatogénesis en los gatos y conejos a 4.000 mts. sobre el nivel del mar. El autor estudia las características del semen estándar de animales (carneros) y da métodos directivos de la investigación para comprobar su hipótesis. Habiendo una vez determinado el "Semen estándar" de la altitud, el autor llega a la conclusión de las posibilidades de mejora de la fertilidad mediante la selección de carneros aclimatados. No tiene en cuenta el problema de los llamados "Machorras" (ovejas infértiles) ya que ha obtenido el 86% de la fertilidad, y hace un estudio comparativo de las razas más adecuadas para la aclimatación.Universidad Nacional Mayor de San Marcos, Facultad de Medicina Humana1942-07-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistasinvestigacion.unmsm.edu.pe/index.php/anales/article/view/970310.15381/anales.v25i1.9703Anales de la Facultad de Medicina; Vol. 25 No. 1 (1942); 19-33Anales de la Facultad de Medicina; Vol. 25 Núm. 1 (1942); 19-331609-94191025-5583reponame:Revistas - Universidad Nacional Mayor de San Marcosinstname:Universidad Nacional Mayor de San Marcosinstacron:UNMSMspahttps://revistasinvestigacion.unmsm.edu.pe/index.php/anales/article/view/9703/8507Derechos de autor 1942 Carlos Monge M.https://creativecommons.org/licenses/by-nc-sa/4.0info:eu-repo/semantics/openAccessoai:ojs.csi.unmsm:article/97032020-04-04T11:57:18Z
