Lateral hermaphroditism and seminoma in a dog.
A 3.6-year-old female Collie was found to have a functionally active ovary and an azospermic testis containing several seminomas. The bitch had had 3 irregular estrous cycles. An ovariohysterectomy was performed, and the histopathologic diagnosis was lateral hermaphroditism and seminoma. Canine intersexes generally have been thought not to have estrous cycles. However, as evidenced in this case, estrous activity can occur. From this report, it is suggested that bitches having irregular estrous cycles should be evaluated for intersexuality.
