Reproductive System of Giraffe (Giraffa camelopardalis)

  • Published : 2009.12.31

Abstract

Two postmortem male and female reticulated giraffes were examined. The adult male giraffe showed sigmoid flexure of penis similar to most ungulates. Epididymis was well-developed and divided with head, body and tail parts. On the tip of penis, there was a urethral process. At the necropsy of a 20-month-old and nulliparous giraffe, ovaries, oviducts, two uterine horns with a septum and a cervix were distinctively shown. Understanding reproductive organs of giraffes would be beneficial to succeed in artificial breeding on this species especially in the difficult situation of importing hoofed animals.
