Species ______________SB# __Sex___ Name______Age

Dicerorhinus sumatrensis      19           F          Mas Merah    ~22+

Captive years without reproducing: 14

Recent breeding activity: Never bred (mounted but not bred in April 2000).

Progesterone profile: Irregular cyclic pattern suggestive of formation and lutenization of hemorrhagic follicles.

Hormone manipulations: Attempted CIDR implant plus PGF2alpha in March 2000 without success. Implanted with Synchromate in Left flank in April 2000 for 9 days with no estrus observed.

Purpose of exam: Examine for reproductive function and pathology.

Brief Summary of Findings:

Interestingly, Mas Merah had what appeared to be a 26 mm preovulatory follicle on her left ovary (Figures 1 and 3) and based on this information the decision was made to attempt an introduction of this female with Ara. Mas Merah appeared to have a normal reproductive tract with only one small endometrial cyst in an area of uterine hyperplasia with no distinct masses as had been previously reported. more »
