“…The endoscopic approach described here has now been further expanded. It has been used to determine oestrous cycle-dependent alterations of pro-inflammatory factors in the bovine oviductal epithelium post partum in dairy cows ( Neubrand et al, 2021 ; Pothmann et al, 2022 ), for the intratubal insemination of sperm from various treatments ( Radefeld et al, 2018 ), as well as the collection of fluid from the oviduct for the determination of stage-specific tubal components ( Pothmann et al, 2017 ; Papp et al, 2019 ; Havlicek et al, 2022 ; Neubrand et al, 2022 ).…”

It can be assumed that the natural processes of selection and developmental condition in the animal provide the best prerequisites for embryogenesis resulting in pregnancy and subsequent birth of a healthy neonate. In contrast, circumventing the natural selection mechanisms and all developmental conditions in a healthy animal harbors the risk of counteracting, preventing or reducing the formation of embryos or substantially restricting their genesis. Considering these facts, it seems to be obvious that assisted reproductive techniques focusing on early embryonic stages serve an expanded and unselected germ cell pool of oocytes and sperm cells, and include the culture of embryos outside their natural habitat during and after fertilization for manipulation and diagnostic purposes, and for storage. A significant influence on the early embryonic development is seen in the extracorporeal culture of bovine embryos (in vitro) or stress on the animal organism (in vivo). The in vitro production per se and metabolic as well as endocrine changes in the natural environment of embryos represent adequate models and serve for a better understanding. The purpose of this review is to give a brief presentation of recent techniques aimed at focusing more on the complex processes in the Fallopian tube to contrast in vivo and in vitro prerequisites and abnormalities in early embryonic development and serve to identify potential new ways to make the use of ARTs more feasible.

“…The pigs were eventually euthanized to obtain tissue samples and pathological specimens. Compared with the sacrificing of animals, the application of endoscopy in research studies is considered a minimally invasive and more humane method, along with assessing the intestinal condition of the animals and obtaining tissue specimens (35)(36)(37).…”

“…Due to the complex animal ethics and experimental methodology, only a small number of studies have been performed using canine models. It has been suggested that endoscopy should be used in experiments with large animals, as it is simple and may reduce the level of trauma to animals (35,37). Furthermore, endoscopy may be used repeatedly to obtain a more accurate assessment of the disease status.…”

Anal fistula is a common and serious complication of Crohn's disease (CD). A sufficiently suitable animal model that may be used to simulate this disease is yet to be established. The aim of the present review was to summarize the different characteristics and experimental methods of commonly used animal models of CD with anal fistula. Electronic databases were searched for studies reporting on the use of this type of animal model. A total of 234 related articles were retrieved, of which six articles met the inclusion criteria; these were used as references for the present review article. The characteristics of the animal models, the advantages and disadvantages of the modeling methods and the similarities with patients with CD and anal fistula were summarized and analyzed. The evidence suggests that a sufficiently suitable animal preclinical model requires to be established.
