Anatomy of the reproductive tract

Does

  • Does have no uterine body, two separate uterine horns Reproductive anatomy 01: uterine horns  and two cervices opening into the vagina Reproductive anatomy 02: cervix and vagina.
  • The vagina is large and flaccid. The mesometrium (broad ligament) is a major site of fat deposition.
  • The placenta is hemochorial.

Bucks 

  • Bucks have two hairless (or sparsely haired) scrotal sacs positioned on either side of and cranial to the penis.
  • There is no os penis.
  • The inguinal canals remain open throughout life and the buck has the ability to consciously retract the testes into the abdomen.
  • Testes descend by approximately 12 weeks of age and castration Castration can be carried out from this time.
  • Cryptorchidism is reported in the rabbit and, as in other species, is associated with testicular neoplasia. True cryptorchid rabbits usually lack a scrotal sac on the affected side.

  • Sexing of young rabbits can be difficult.
  • In males the urogenital opening is round Sexing 02: male genitalia, whereas in the female the vulva is slit-like Sexing 01: female genitalia.
  • The anogenital distance is greater in the male.
