Afecciones congénitas que generan problemas reproductivos en equinos

Abstract

Equines are characterized by having the highest rate of chromosomal anomalies compared to other species, related to conditions in the sex chromosomes; according to the literature. These alterations can be influenced by genetic or environmental factors such as teratogenic agents which cause imbalance or alteration of the genome, to cause genotypic or phenotypic malformations. In causality, the reproductive part of the horse is affected and manifests itself in different ways according to gender, causing in most cases infertility or subfertility. Chromosomal alterations in these specimens lead to pathologies such as Klinefelter syndrome, Turner syndrome and pseudohermaphroditism; affecting the equine population with cryptorchidism problems (no descent of the testes), ovarian hypoplasia or gonadal dysgenesis (63, XO) and adrenal hyperplasia. Consistent with the above and the complexity of the karyotype of the horse, different methodologies for diagnosis and treatment have been arranged, as appropriate. Next, an article of informative type is presented, where scientific data are collected in relation to the aberrations named before.
