Male pseudohermaphroditism in a cat

J Small Anim Pract. 1997 Jan;38(1):21-4. doi: 10.1111/j.1748-5827.1997.tb02981.x.


A seven-month-old male pedigree cat was brought to the Norwegian College of Veterinary Medicine for routine castration. Visual examination of the external genitalia revealed a wide genital cleft with non-fused bilaterally located testicular pouches. A large clitoris, which was penis-like with small penile spines, was seen protruding dorsally from the ventral commissure of the genital cleft. During an exploratory coeliotomy, no intra-abdominal genital structures of müllerian origin were found. The skin pouches on either side of the vulvar cleft were incised and grossly normal testicles were removed. Histology of the removed gonads showed no or very sparse spermatogenesis. The chromosomal sex was determined by karyotyping to be a normal male 38XY. Based on these findings, the diagnosis of male pseudohermaphroditism was made. The aetiology of the condition in this cat was not determined.
