Gross and microscopic anatomy of the reproductive tract of the female agouti (Dasyprocta leporina): A neotropical rodent with potential for food production. (38)
This study investigated the gross and microscopic anatomy of the reproductive tract of five cage reared female agouti (Dasyprocta leporina). The ovaries were paired yellow ovoid bodies with a mean (± SD) length of 10 mm (± 2.1), held near the caudal pole of the kidneys. The ovarian cortex consisted of cellular connective tissue in which ovarian follicles were embedded. Highly vascularized tissue was noted in the ovarian medulla. The fallopian tubes increased in width caudally from the ovary to the uterus. Paired uterine horns converged to form the Y-shaped uterine body and the characteristic duplex uterus was separated by a septum. The cervix was found at the pelvic inlet and protruded into the proximal vaginal lumen as the fornix. The vagina had a mean (± SD) length of 7 cm (± 11.4), representing the longest portion of the reproductive tract. Differences in vaginal epithelium were evident, indicating that vaginal colpocytology may be used to evaluate the reproductive stage of the female agouti in captivity. The distance between the urethral aperture and the anus may be used to determine the sex of cage reared agouti, especially when the perineum seals the vaginal orifice.
