“…Recently, Abiaezute and Nwaogu (2015) recorded postnatal developmental changes in the length and weight of the vagina of the female West African dwarf goat. Bal and Getty (1972) previously described changes with maturity in the vaginal histological structures of the domestic pig. In the female guinea pig, Cooper and Schiller (1975) recorded that the end of the reproductive tract is lack of vestibule and the vagina was ended by the external vaginal orifice.…”

This project was carried out to find out the structural histomorphological changes that take place in the pelvic parts (vagina and vestibule) of the female reproductive system of the rabbits (Oryctolagus Cuniculus) at three different postnatal periods of their life that were kitten, immature and mature does. To conduct such project, twenty four female rabbits were bought (8 for each age) from the local breeders. Rabbits were euthanized, dissected and subsequently vaginae and vestibules were collected and fixed with 10% neutral buffered formalin then subjected to routine processing, such as dehydration, clearing, embedding and block preparation. Finally, sectioning for 6 µm were prepared and stained with hematoxylin-eosin and Masson's trichrome stains. Gross findings revealed that the vagina and vestibule in the local rabbits were characteristically very long tube-like structures. The vagina entirely was running ventral to the rectum together with vestibule in the pelvic cavity. Microscopic findings revealed prominent structural changes in the vagina of immature does compared to those of kittens and mature does indicated that immature does after the period of weaning face great developmental growth and changes. The microscopic changes in the vestibule were slight alterations and no age related changes were recorded. Statistical analysis revealed that the total thickness of the mucosa plus muscularis of the vaginal wall was decreased significantly in the direction cranio-caudally.In conclusion, the current study recorded differences in both macroscopic and microscopic aspects of the vagina and vestibule of the local rabbits compared to other animal species.

“…Bal and Getty (1972) have also described changes with maturity in the vaginal histology of the domestic pig. Immature females had regular and uniform vaginal epithelium, varying in height between females from 1 to 4 cell layers in some cases to 18 layers (Figures 9 and 10), sometimes with Vol.…”

In preclinical studies, it is important to know whether the animals used are sexually mature or not. Precise data have not yet been published, however, about the histological features of the female reproductive organs during the peripubertal period or about the age of acquisition of sexual maturity in the minipig. The histological characteristics of the genital organs of female control minipigs from toxicology studies were described and, based on the presence of ovarian corpora lutea, used to assess the age at which maturity was reached. Only 50% of females can be considered mature at about 6.5 months old (a body weight of 11.8 kg), and 100% were not mature until about 7.5 months old (13.1 kg), although it is said that females reach sexual maturity at the age of approximately 5 months, by the time the body weight is about 10 to 12 kg. The uterine weights of mature females were higher than 94.4 g, whereas the maximum weight reached in the immature females was 55.2 g. In contrast, the differences between immature and mature ovarian weights were not significant. The histological appearance of the mature vagina in the various stages of the estrous cycle is also described.

“…The mucosa-submucosa had areolar tissue which appeared spongy due to the presence of many blood vessels. Both the arteries and veins are lined only with endothelium, being devoid of a muscular coat (Bal & Getty, 1972). In rabbit, the vaginal wall is distinctly lined by simple columnar cells (Dehkordi & Parchami, 2012).…”

SUMMARY:The camel (Camelus dromedarius) is an important multipurpose livestock species and its meat represents about 10% of the red meat consumption in Egypt. The reproductive efficiency of camel under natural condition is generally considered to be low. Sound knowledge about the tubular genital organs of this species might facilitate the application of new reproductive methodology. Our study was therefore conducted to investigate the morphology of mucosal surface of vagina and vestibule on camels using light, scanning and transmission electron microscopy. The mucosal surface of vagina consisted of stratified columnar epithelium with mucous secreting cells (goblet-like cells). SEM of vagina revealed the presence of longitudinal primary and secondary folds and small transverse folds. The columnar epithelium showed marked cell boundary and its apical surface was studded by a lot of microvilli. TEM confirmed the presence of microvilli at apical surfaces and showed some secretory granules in the supranuclear region of the columnar epithelium. The vestibule of dromedary camel was lined by stratified squamous keratinized epithelium. Basal lamina and stratum granulosum of this epithelium showed strong PAS positive reaction. SEM of vestibule revealed the presence of small longitudinal and fine transverse folds with a lot of mucous debris. However TEM of vestibule showed the stratified squamous keratinized epithelium with basal layer of cuboidal cells and superficial layers of squamous cells.
