Plain-English summary
An 8-year-old intersex male dog, who appeared female, was brought in for a mass in the right groin area. During surgery, vets found a large tumor that looked like a testicle and a smaller, atrophied testicle on the other side. The larger mass was diagnosed as a Sertoli cell tumor, while the smaller one contained a seminoma. After removing both masses and the testicles, hormone levels were checked and showed high progesterone before surgery, which returned to normal after a month. The dog recovered well after the surgery.

Abstract
This case describes the presentation and management of an 8 yr old phenotypically female intersex male dog presented for evaluation of a mass in the right inguinal region. The right inguinal space was surgically explored, and a large irregular mass resembling a fully developed testicle was identified in the right vaginal tunic. A second mass resembling an atrophied, but anatomically mature testicle, was identified in the left tunic. The larger mass was identified as a Sertoli cell tumor that had replaced all normal testicular tissue. The smaller mass was identified as a testicle that contained a small intratubular seminoma. The patient was diagnosed as having a phenotypic female sex, chromosomal male sex, and a gonadal male sex. Hormone assays completed before and after the gonadectomy and mass removal document an elevation of circulating progesterone presurgically that returned to baseline by 1 mo postsurgically. The source of the progesterone was identified to be the Leydig cells of the atrophied testicle.
