Detailed Explanation of the Reproductive Organs and Physiological Characteristics of the Female Fox

Livestock Farming 0 views
The reproductive organs of the female fox consist of the ovaries, fallopian tubes, uterus, vagina, and external genital organs. The external genital organs include the vestibule of the vagina, labia, and clitoris. The ovaries of the female fox are located at the third and fourth lumbar vertebrae, at the posterior margin of the kidneys. The left ovary is positioned more anteriorly than the right ovary. The ovaries are flat in shape and grayish-red; during estrus, the ovary is 2 cm long and 1.5 cm wide; the fallopian tubes are 5-7 cm long. The ovaries and fallopian tubes are covered by adipose tissue. The uterus is a bicornuate uterus, with the uterine horns and uterine body suspended by the broad ligament of the uterus on the lower lateral walls of the pelvis. The uterine horns are 10-13 cm long, the uterine body is 4-6 cm long, and the cervix protrudes into the vagina. The vagina is 6-8 cm long, with its anterior end connected to the cervix and its posterior part adjoining the urogenital vestibule. The vestibule has two relatively well-developed protrusions, mating. During mating, the vestibule is stimulated and contracts violently, the two lateral protrusions swell, and together with the bulbous body of the male fox's penis, this results in a copulatory tie. The vulva of the female fox, together with the bulbous body of the male fox's penis, results in a copulatory lock. The vulva of the female fox is round on top and pointed at the bottom; outside the breeding season it is covered by pubic hair and not visible; during the breeding season it shows morphological changes.
