Genital abnormalities associated to lack of uterine adenogenesis or endometrial gland dysgenesis of female dromedary camels (Camelus dromedarius).

Abstract

Background:The developmental disruption of the müllerian duct and the endometrial dynamic can generate genital lesions that could contribute to infertility.Aim:This paper discusses two cases of genital conditions associated to endometrial gland pathologies in nulliparous female camels.Methods:Macroscopic examinations and histopathological description were performed on congenital and acquired genital abnormalities with endometrial gland anomalies.Results:The first case is endometrial gland agenesis associated to unilateral uterine aplasia, and the second case is endometrial gland dysgenesis associated to metritis. The prevalence of each case is estimated to be 0.6%. The most specific microscopic features associated to the endometrial gland agenesis were the presence of endometrial stromal proliferation and homogenous hyalinization of the myometrium. The acute metritis was associated to endometrial-activated stroma with focal infiltration with inflammatory cells on the endometrium and myometrium and the spontaneous endometrial gland dysgenesis.Conclusion:This study reveals the importance of congenital abnormalities during the routine reproductive examination of peripubertal animals, as well as the association of histopathological complementary examination for the research functional and inflammatory anomalies of the uterus. Genetic screening of breeders would be very important in the search for genetic risk factors associated with these congenital pathologies, which can be disseminated by reproductive biotechnologies.
