  • In this paper,we make anatomical and histological observation on the female reproductive organs of two giant pandas,one in rutting period,the other the pre-oeatrus period.The analyses show the following results:1)On the surface of a four year old female ovary,there are clegts,which are just the same as described by Davis,Dwight D.(1964).But we observe the surface of a ten to fifteen year old female ovay is smooth.2)The primary ovocytes are scattering or in groups on the cortical layer and the secondary follicles,the approximately matured growing follicles and the matured follicles are distributed in the cortical substance and the outer medullary substance layer,or overlapping in groups on the surface of the ovary.3)During the rut period,the left ovary appears bigger than the right one,and its follicules are protruding and overlapping in groups,while the surface of the dexter ovary is smooth,and follicules do not protrude out.4)By analysing the giant panda farrowing records,every female ovulates out 1-2 ova in its rutting period,very raritily 3.A great quantity of approximately matured and matured follicules retrograde into atretic follicules.It is of theoretical significance in the field of mammalian evolution.5)The oviduct is very short and its contortion is small Adult cornus uteri is divided into thick and thin section,its septum developed.The cervix is stratified epithelium,its tunica intima has no gland.
