İngilizce (OpenAlex)

Congenital malformations of the reproductive system are rarely encountered in queens and etiology is not known precisely. Agenesis of the ovary is one of the congenital anomalies and usually found incidentally during laparotomy operations. In this case, a 2-year-old female cat referred to the clinic for ovariohysterectomy is described. Before anesthesia and surgery, a routine examination was performed. In physical examinations and results of blood samples did not reveal any problem for the operation. After the pre-operative process, ovariohysterectomy was performed. Ovary and the uterine horn were identified on the right-side. However, only the uterine horn without any abnormality was detected on the left-side. The cat was diagnosed with unilateral ovarian agenesis. Then, a blood sample was taken to determine serum steroid hormone levels. Serum estradiol and progesterone levels were measured as 18 pg/ml and 1.4 ng/ml, respectively. As a conclusion, unilateral ovarian agenesis that is incidentally detected the laparotomy procedures were no adverse effect on sexual activity in queens.
