True Hermaphroditism in a Dog: A Case Report

True hermaphroditism in a dog is described in this case report. An eight month old cross-breed dog with enlarged structure protruding from the vulva was brought for an ovariohysterectomie operation. Physical examinations exposed the presence of an os clitoris and urethral orifice at the base of the os clitoris. Exploratory laparotomy was performed as a diagnostic and therapeutic procedure. Both gonadal tissues and the genital tract were removed during surgery and brought to the laboratory for pathological examinations. Microscopic examinations showed that the right gonad had both seminiferous tubules like testis and primer follicles like ovarium. The concentrations of serum progesterone, testosterone and 17β-estradiol were 0,188 ng/ml, 1,008 ng/ml and 23,61 pg/ml respectively. We concluded that this is a true hermaphrodismus case due to the simultaneous presence of two sex gonads
