Sumatran Rhino Reproductive Evaluation
Sungai Dusun, Malaysia
Date of exams: 30 August, 4 September and 5 September 2001

Species ______________SB# __Sex___ Name___Age

Dicerorhinus sumatrensis       23          F          Seputeh   ~22

Captive years without reproducing: 13

Recent breeding activity: Multiple breedings approximately every 21 days since January of 2001. Seputeh appears to consistently breed for 2 consecutive days.

Progesterone profile: History of 21 day cyclical pattern.

Hormone manipulations: None.

Purpose of exam: Examine for reproductive function and pathology.

Brief Summary of Findings:

Seputeh has a vascularized mass measuring 50 mm in diameter located in the tissues surrounding her caudal reproductive tract (Figures 1 and 2). Numerous other smaller masses are associated with Seputeh’s uterine body and uterine horns. As suggested by Dr. Roth, it is conceivable that Seputeh may be conceiving and undergoing early embyonic loss. The significant pathology in this female associated with the reproductive tract and surrounding anatomy suggest that Seputeh’s chances of normal embryo development and implantation would be unlikely to occur. Despite observed pathology, Seputeh appears to be cycling normally as illustrated by the observation of luteal tissue on the right ovary (Figure 3) and subsequent formation of a preovulatory follicle followed by documentation of successful ovulation within 24 hours post-breeding (Figures 4, 5 and 6). more »
