This study histopathologically examined uterine biopsies from dairy cows with and without endometritis to assess the relationship with adenomyosis, finding a numerically higher prevalence in cows with endometritis.

This study investigated the association between adenomyosis and endometritis in dairy cows by comparing uterine biopsy specimens from animals with and without uterine infections. Histopathological analysis revealed a prevalence of 5.4% for adenomyosis in the endometritis group versus 0% in the control group, although logistic regression determined that this difference was not statistically significant. The authors concluded that while there is a numerically higher occurrence of adenomyosis in infected cows, no definitive link was established within this sample size. Relevance to endometriosis: listed as one indication for GnRH antagonists, though the paper's main focus is uterine fibroids.

Abstract

Adenomyosis is the invasion of endometrium into the myometrium, which could reduce fertility in cows. The aim of the present study was to assess the relationship between the occurrence of adenomyosis and endometritis in dairy cows. Cows in the control group (n = 33) had no uterine infection, while cows in the case group (n = 37) had endometritis. To harvest uterine specimens, cows in both groups were subjected to uterine biopsy. The uterine specimens were fixed in 10 % formalin, embedded in paraffin, sectioned, stained with hematoxylin and eosin (H&E), and examined histopathologically. Data were analyzed using logistic regression analysis. The prevalence of adenomyosis was 5.4 % (2/37) and 0 % (0/33) in cows with endometritis and control cows, respectively, and there were no significant differences between the two groups (P > 0.05). In conclusion, the present study showed a numerically higher prevalence of adenomyosis in cows with endometritis. Similar content being viewed by others
