Vaginal and cervical modifications during the estrus cycle in the domestic cat.
A thorough knowledge of the genital tract anatomy and vaginal and cervical modifications during the phases of estrus cycle of the female cat is necessary to enhance success of assisted feline reproductive technologies or for other diagnostic or therapeutic purposes. There are few studies of the gross anatomy of the genital tract in the queen. The vestibule is large in comparison to the vagina; the latter has a narrow lumen, which is further constricted by the prominent dorsal median fold. The cervix is oriented obliquely between the uterine body and vagina. Vaginal and cervical changes in association with the estrous cycle have been reported in some species and two recent studies investigated this aspect in the cat. This paper reviews the relevant literature, with particular emphasis on recent studies.
