“…Oviductal segments were fixed overnight in Bouin–Duboscq fixative, histologically processed and transversally cut at a thickness of 7 μm with a microtome (Model RM 2135; Leica, Wetzlar, Germany) as described elsewhere (Pedrero‐Badillo et al. ). A serial group of slides was stained with the Masson's trichrome technique, and oviductal regions were identified as previously reported (Pedrero‐Badillo et al.…”

“…A serial group of slides was stained with the Masson's trichrome technique, and oviductal regions were identified as previously reported (Pedrero‐Badillo et al. ). Slides from the junction of fimbria‐infundibulum (FIM‐INF), the central portion of the ampulla (AMP) and the isthmus (IST), as well as the most cranial portion of the utero–tubal junction (UTJ) were sampled.…”

“…Considering the clear regionalization of rabbit oviduct, particularly that concerning to epithelium and smooth muscle (Pedrero‐Badillo et al. ), we presently hypothesized that hypothyroidism affects differentially the histology of oviductal regions. The aim of this study was therefore to analyse the impact of the pharmacologically induced hypothyroidism on the histological characteristics of oviductal regions in rabbits.…”

Oviductal regions show particular histological characteristics and functions. Tubal pathologies and hypothyroidism are related to primary and secondary infertility. The impact of hypothyroidism on the histological characteristics of oviductal regions has been scarcely studied. Our aim was to analyse the histological characteristics of oviductal regions in control and hypothyroid rabbits. Hypothyroidism was induced by oral administration of methimazole (MMI) for 30 days. For both groups, serum concentrations of thyroid and gonadal hormones were determined. Sections of oviductal regions were stained with the Masson's trichrome technique to analyse both epithelial and smooth muscle layers. The percentage of proliferative epithelial cells (anti-Ki67) in diverse oviductal regions was also quantified. Data were compared with Student t-test, Mann-Whitney U-test, or Fischer's test. In comparison with the control group, the hypothyroid group showed: (i) a low concentration of T3 and T4, but a high level of TSH; (ii) similar values of serum estradiol, progesterone and testosterone; (iii) a large size of ciliated cells in the ampulla (AMP), isthmus (IST) and utero-tubal junction (UTJ); (iv) a large size of secretory cells in the IST region; (v) a low percentage of proliferative secretory cells in the fimbria-infundibulum (FIM-INF) region; and (vi) a similar thickness of the smooth muscle layer and the cross-sectional area in the AMP and IST regions. Modifications in the size of the oviductal epithelium in hypothyroid rabbits could be related to changes in the cell metabolism that may impact on the reproductive functions achieved by oviduct.

“…Such as in the pig, cow, sheep, goat and other mammals, the mare oviduct presents different curves or convolutions, whose shape varies at different morphological regions of the fallopian tube. Duct tortuosity is closely related to the oviduct length (Hunter, ), such as in the female rabbit, which has short and practically straight oviducts (Pedrero‐Badillo et al, ). In sows, the length (and degree of sinuosity) increases after first estrus post‐weaning (Rigby, ), and in cows the fallopian tubes growth is completed after puberty (Hunter, ).…”

“…The internal morphometry of the different tubular regions of the oviduct have been studied in rabbit (Leese, ; Pedrero‐Badillo et al, ), bovine (Yániz et al, ), swine (Suárez, ), ovine (Yániz et al, ), and canine (England et al, ) oviducts. These previous studies described the internal diameter, the luminal area, luminal perimeter, and area of folds protruding into the oviduct lumen.…”

The objectives of this work were to describe some morphometric characteristics and to establish quantitative parameters of different regions of the equine oviductal mucosa from the isthmus, ampullaryisthmic junction (AIJ), and ampulla. Twenty-one mixed-bred mares were used for this study. Mares were selected in the following reproductive phases: anestrus, estrus, and diestrus. The left oviducts were examined with light microscopy, and rights ones were studied through the intraoviductal molds. The isthmus showed the smallest luminal area, mucosal area, epithelial perimeter, and luminal diameter. On the molds surfaces, some grooves extended as longitudinal canals, reducing their depth as they approached to the AIJ. Several small height projections, some obliquely positioned towards utero-tubal junction, were observed in all reproductive phases. These formations may represent pockets or cul-de-sacs in the basal areas of the epithelial folds. The AIJ mucosa gradually changed from the smooth isthmic region toward highly folded ampulla. The number and complexity of epithelial folds showed moderate increase in the same way that many of the morphometric parameters. Multiple curves were observed on the molds of the AIJ, creating a zigzag path in the oviductal lumen. In the ampulla, the high branched epithelial folds occupied most of the lumen, leaving a small luminal area free. A linear relationship between epithelial perimeter and mucosal area was found.
