Plain-English summary
Two cryptorchid dogs (dogs with undescended testicles) were brought in because they were losing hair and losing weight. Both dogs had signs of feminizing syndrome, like an enlarged prepuce and prostate, due to functional Sertoli cell tumors, which produce estrogen. During surgery, the vets found that the dogs also had twisted spermatic cords along with the tumors. After removing the affected testicles, both dogs showed complete recovery from their symptoms within three months.

Abstract
The association of cryptorchidism, functional Sertoli cell tumors, and spermatic cord torsion has been rarely reported in the literature. Two dogs were admitted for bilateral skin alopecia and weight loss. Both animals were cryptorchid and displayed a pendulous preputial sheath, prostate hypertrophy, and increased levels of circulating oestrogen. Transabdominal palpation and ultrasonography revealed the presence of neoplastic retained gonads. During surgery, spermatic cord torsion was also detected in the enlarged neoplastic testes of both dogs. Histologic examination confirmed the presence of Sertoli cell tumors that were primarily responsible for the feminizing syndrome. Complete remission of all symptoms occurred within 3 months after orchiectomy.
