Microscopic features of the adult rabbit uterine tube during estrous cycle were studied. Twenty rabbit uterine tube were used. Rabbits were collected from local market. Sections from uterine tube infundibulum, ampulla and isthmus were prepared for histological study. Lengths and widths of various parts were obtained from the right tube. Ampulla formed the longest part, isthmus was narrowest segment and connected to the uterus. The infundibulum was with fimbrae. Epithelial liming was with few types of cells, and were; ciliated; non-ciliated secretory (peg cells) and basal cells were also demonstrated. The type of epithelial cells was pseudostratified epithelium. In the ampullary mucosa, large number of primary branches at the follicular phase was observed. Ciliation was more at the follicular phase than luteal phase. While secretory cells during follicular was less than that at luteal phase

“…The increased secretory activity of the tubal cells in cows with FC is confirmed by the results of our TEM studies which revealed abundant amounts of highly active dilated rough endoplasmic reticulum and numerous cytoplasmic SG. Increased carbohydrate synthesis has already been reported during the cycle—especially during the follicular phase (proestrus/estrus) of cycling cows (McDaniel et al, 1968), rabbits (Özen et al, 2010) and rodents (Machado‐Neves et al, 2019), as well as in estrogen‐treated cows (McDaniel et al, 1968)—and this has been shown both at a histochemical and ultrastructural level (Bjorkman & Fredricsson, 1961; Eriksen et al, 1994) pointing to the possibility that the alterations in FC cows are driven by the high levels of estrogen. Progesterone, on the other hand, is the dominant steroid hormone during the luteal phase (diestrus; days 10–15) and is elevated in LC cows.…”

Cystic ovary disease (COD) is a common cause of subfertility in dairy cattle. Therefore, the aim of this study was to provide novel concepts for cyst classification and to investigate the effects of COD on tubal microarchitecture, oviductal metabolic function, and the formation of the sperm reservoir. Bovine Fallopian tubes affected by follicular cysts, follicular cysts with luteinization and luteal cysts were investigated by a variety of microscopic and histological techniques and compared to control cows in metestrus and diestrus. We defined three types of cysts involved in COD, each of which had a characteristic wall thickness, inner wall appearance and cellular pattern within the cyst aspirate. Regarding the Fallopian tube, each cyst type was associated with a characteristic morphology, specifically the microarchitecture of the folds in ampulla, epithelial cell ratios, and ciliated/secretory cell size and form. Furthermore, each cyst type showed different patterns of tubal glycoprotein and acidic mucopolysaccharide synthesis, which was highly variable as compared to the controls. Our studies are the first to characterize the effects of COD on the Fallopian tube, which promotes the establishment of novel, cyst‐specific therapeutic concepts in cattle and helps gain a holistic view of the causes of subfertility in cows with COD.

“…The cervix and uterine horns actively participate in the delivery mechanism, in order to expel the fetus from the uterine environment [16]. On the other hand, the uterine tubes are responsible for gametes transportation, sperm capacitation, oocyte fertilization, embryo development, as well as embryo migration to the implantation site in the uterus [17].…”

The objective of this study was to characterize the reproductive organs of prepubertal gilts through morphometric analyzes. To perform these analyzes, the reproductive organs of eight prepubertal gilts (n=8) were collected and dissected immediately after slaughter. The morphometric evaluation revealed no significant differences between antimeres (left vs right). Likewise, in the histological evaluation no significant difference was found in the height of the epithelium of the reproductive organs evaluated. In addition, it was possible to characterize the predominant epithelium of the collected parts of the uterine tubes, horns and body. In the uterine tubes the predominantly type of epithelium identified was the simple ciliated columnar, whereas in the uterine body and horns the pseudostratified ciliated epithelium predominates. The diameter of the endometrial glands measured from the uterine body and horns samples did not differ significantly (p>0.05). On the other hand, the follicular diameter differed significantly among the follicular categories evaluated (p<0.01): primordial (24.88±0.22μm), primary (29.65±0.47μm) and secondary (113.96±7.29μm). In conclusion, the reproductive organs of prepubertal gilts did not show significant differences in the analyzed morphometrical parameters. However, the values obtained in this study can be used as physiological values for prepubertal gilts.
