Abstract
Two cases of bovine male pseudohermaphrodites (PH) were subjected for clinical investigation with transrectal ultrasonography, endocrinology with adoption of hCG-stimulation test, cytogenetics with analysis of sex chromosome and Y-specific DNA, and finally histological examination. Results were compared with normal calves. Case 1 was a 10-month-old calf with XX/XY chimeras, showing elevation of testosterone (T) levels, but no change in progesterone (P(4)) after hCG test, and possessed atrophied testes in the cavitas pelvis. Case 2 was an 18-month-old calf with SRY positive-XY chromosome, showing lower level of plasma T and P(4) after hCG test, and possessed atrophied testes and undifferentiated genital ducts. Both cases possessed female-like external genitalia with similar pathological findings, however endocrinological and cytogenetical aspects were different each other.
