“…The higher incidence of ovulation from the right ovary than the left (57-8 versus 42-2%, = 516) confirmed previous reports (Reece & Turner, 1938) but this did not affect progester¬ one levels. The highly significant relationship between progesterone levels and length of oestrus was unexpected.…”

“…Various reports have shown that more ovulations, and consequently more pregnancies, occur on the right side in the bovine (Clark, 1936;Reece & Turner, 1938;Kidder, Barrett & Casida, 1952;Hafez & Sugie, 1963). This same trend was observed here, the ratios of the right to left activities of the uterus and ovaries being fairly constant.…”

Records from both beef and dairy cows were used to test for utero-ovarian relationships during post-partum anoestrus. It was found that ovarian activity (follicular development and ovulation) first occurred in the ovary opposite the side of the recent pregnancy in a significant majority of the observations. This tendency was greater in the dairy cows. The proportion of cows with ovarian activity on thè opposite side' tended to decrease as the length of the interval from calving to ovarian activity increased. However, the average length of the interval from calving to follicular development or ovulation did not differ significantly between`same side' and`o pposite side' animals.Cows served at the first ovulation after calving had better conception rates when the ovulation occurred on the side opposite the previous pregnancy. This difference between the two sides was greater for cows whose uteri had not yet involuted at the time of service.

“…It seems logical to find higher odds for the detection of PMNs in the corpus uteri as this is the location most proximal to the cervix, the latter being the evacuation site of uterine debris towards the external environment. The fact that in cattle more pregnancies are allocated in the right than in the left uterine horn (Rajakoski, ; Reece & Turner, ) and the concomitant mechanical effect of the foetus during parturition may furthermore explain why we detected greater PMN counts at the bifurcation of the right horn. Correspondingly with the higher PMN counts detected in the corpus uteri and the right horn, the odds to detect mononuclear cells in these regions were also higher.…”

Objectives of this study were twofold: (i) to assess the association between polymorphonuclear (PMN) counts and chronic alterations within the bovine endometrium and (ii) to determine the distribution of inflammation throughout the endometrium of clinically healthy dairy cows. Holstein-Friesian cows (n = 32) from a single dairy farm were selected for this experiment. Before slaughtering, a complete reproductive examination was performed to discard any type of clinical disease. After slaughtering, reproductive tracts were collected, and the endometrium was sampled at 8 pre-defined locations. At each location, endometrial biopsies (EBs) and cytology (CY) samples were harvested. Histopathology samples were stained with haematoxylin-eosin (EB-HE) and naphthol-AS-D-chloroacetate-esterase (EB-naphthol), while CY samples were stained with Wright-Giemsa. In the EB-HE samples, parameters assessed were epithelium height, mononuclear cells infiltration, lymphocytic aggregates, periglandular fibrosis, angiosclerosis and haemorrhage. In EB-naphthol and CY slides, PMNs counts were evaluated. Binomial logistic regression was used to assess the association between the number of PMNs present in both the EB-naphthol and CY samples and alterations identified in the EB-HE samples and to analyse the distribution of the histopathological alterations (EB-HE). A Poisson mixed-effect model was used to analyse the distribution of PMNs within the endometrium. A significant positive association was found between the PMN counts and the mononuclear cells infiltration. The presence of erythrocytes was associated with higher odds to detect PMNs in the stratum compactum. Significantly, higher infiltration of PMNs and mononuclear cells were detected in the uterine body and the right horn region. Concluding, CY is a technique that allows the evaluation of PMN counts and therefore only evaluates active inflammation. A complete assessment of endometrial health can only be obtained using EB. To optimize the sensitivity to diagnose endometrial inflammation in cows, adjacencies of the corpus uteri should be considered as the preferred region to harvest samples.
