Anatomy of adult female common marmoset (Callithrix jacchus) reproductive system.
Better appreciation of the female reproductive anatomy of the common marmoset (Callithrix jacchus) should improve the prospects for nonsurgical embryo transfer in this model. Vaginal measurements were performed in 8 female adult marmoset monkeys. Four monkeys were measured at laparotomy for gross internal anatomy, and 1 monkey was analysed at autopsy. The vagina of the marmoset monkey was found to be divided into a lower and upper vagina with a marked vaginal isthmus between them. The mean lengths of the lower and upper vagina were 17 mm (34 mm in total vagina). The mean uterine size was 8.4 (length) x 10.0 (width) x 6.4 (thickness) mm, with the ovary measuring 5.3 x 4.3 x 3.8 mm. The mean length of the fallopian tube was 10.5 mm with a width of 1.5 mm. Nonsurgical embryo transfer in this model appears to be feasible, but the proportionally long vagina and short uterine cavity needs to be recognised.
