Biometric and morphologic studies of the female reproductive organs of the African giant rat (Cricetomys gambianus: Waterhouse).

Different segments of the reproductive tract of 100 adult, non-pregnant, female African giant rats (AGR) were carefully examined, weighed, and measured. The ovaries were observed to be small, pinkish, and kidney-shaped. The uterus of the AGR was found to be uterus duplex. The live weight of the AGR was 999.7 ± 16.86 g. The weight, length, and width of the ovary were 0.095 ± 0.003 g, 0.750 ± 0.01 cm, and 0.01± 0.02 cm, respectively. The length of the oviduct, uterus, and vagina/vestibule were 4.44 ± 0.06 cm, 4.877 ± 0.11 cm, and 4.345 ± 0.07 cm, respectively. The weight and length of the entire tubular organs were 3.171 ± 0.01 g and 13.559 ± 0.18 cm with corresponding range values of 1.61-7.10 g and 7.80-17.40 cm, respectively.
