Summary To describe the macroscopic anatomy of the genital organs of the female pampas deer ( O zotoceros bezoarticus ), organs from animals dead in a captive breeding station were dissected. A total of twenty females, 17 adults and 10 pre‐puberal approximately 1 year old were studied by gross dissection. The ovaries of adult females without corpora lutea weighed 0.22 ± 0.02 g on the right and 0.20 ± 0.01 g on the left and accounted for 0.03 ± 0.01% of body weight. All corpora lutea (n = 6) were found in the right ovary, but in cases where there was no corpus luteum present, the right ovary tended to be heavier than the left ( P = 0.1). The absence of ovarian bursa, intercornual ligament and suburethral diverticle is peculiar to this deer species. Only 6 convex caruncles were found in the uterine horns, which differ from the more of 100 present in domestic ruminants. Four regular folds that were observed in the cervix of the uterus should not be an obstacle to the passage of a transcervical catheter, allowing intrauterine artificial insemination. The close relationship between the ovarian artery and vein stood up could be associated with the passage of the uterine luteolytic factor from the vein to the ovarian artery, avoiding its systemic way, as happens in domestic ruminants. While the plan of organization was similar, there are some differences with the descriptions of other ruminants. Our results may be very useful as it provides with information that may be considered for the development of female reproductive biotechnologies.
