一只3至4岁的er(CapreoluscapreolusL.)被送往兽医医院。虽然它显示出发育良好的鹿角和保留的天鹅绒,女性外貌和生殖器明显。对鹿角进行了外部生物测量,并进行了计算机断层扫描。进行了针对SRY基因的分子研究,并实施了PIS(调查双性恋综合征)突变诊断.性腺由右睾丸和左睾丸组成。组织学上,卵睾丸中的卵巢样结构是有功能的,但是睾丸,作为睾丸中的睾丸样结构,没有表现出活跃的精子发生。通过PCR没有检测到SRY基因的证据,提示XX染色体构成.此外,在研究中的病例中未检测到接受调查的双性综合征(PIS)缺失。临床和组织病理学发现证实DSD存在睾丸和对侧卵睾丸。
A 3-to-4-year-old roe deer (Capreolus capreolus L.) was admitted to the Veterinary Hospital. Although it showed well-developed antlers with retained velvet, an external female appearance and genitalia were evident. External biometrical measurements were taken for the antlers, and a computed tomography was performed. Molecular studies targeting the SRY gene were performed, and a PIS (polled intersex syndrome) mutation diagnosis was implemented. The gonads consisted of a right testicle paired with a left
ovotestis. Histologically, the ovary-like structures in the
ovotestis were functional, but the testis, as the testis-like structure in the
ovotestis, did not show active spermatogenesis. No evidence of SRY gene was detected by PCR, suggesting an XX-chromosome constitution. Additionally, polled intersex syndrome (PIS) deletion was not detected in the
case under study. The clinical and histopathological findings confirmed the DSD with the presence of a testicle and a contralateral
ovotestis.
