Hermaphroditism is less frequently reported in dogs and is often associated with infertility.
An 8-month-old French bulldog weighing 5 kg with an enlarged structure protruding from the vulva was clinically diagnosed with hermaphroditism. Physical, hormonal assay, computed tomography, and gross and histological studies were done in addition to successfully detailed surgical correction. On physical examination, the dog showed the presence of an os-clitoris protruded from the vulvar labia. Hormonal levels of estradiol, testosterone, and progesterone were 6.39 pg/ml, 0.4 ng/ml, and 8.67ng/ml, respectively. Surgical removal of internal gonadal tissues and os clirectomy operations were conducted after the exploratory laparotomy. The removed gonadal tissues were identical to that of a female with testicles instead of ovaries, according to a gross examination. Histological examination confirmed gonads as testis, with inactive seminiferous tubules and epididymis attached to uterine horns.
The congenital anomalies in the present case were diagnosed as male pseudohermaphroditism (MPH). Surgical correction was performed, and the owner's satisfaction was achieved.
犬的两性畸形较少见,常伴有不育。
一只 8 月龄、体重 5kg 的法国斗牛犬,从外阴部突出一个增大的结构,临床诊断为两性畸形。除了成功的详细手术矫正外,还进行了体格检查、激素检测、计算机断层扫描以及大体和组织学研究。体格检查显示,该犬的阴门有一个阴蒂从阴唇突出。雌二醇、睾酮和孕酮的激素水平分别为 6.39pg/ml、0.4ng/ml 和 8.67ng/ml。在剖腹探查后进行了内部性腺组织和阴蒂切除术。大体检查显示,切除的性腺组织与睾丸而不是卵巢相同。组织学检查证实性腺为睾丸,附有不活跃的曲细精管和附于子宫角的附睾。
本病例的先天性异常诊断为男性假两性畸形(MPH)。进行了手术矫正,主人非常满意。
