Hysterosalpingography in cynomolgus monkeys.

This paper describes recent success in performing hysterosalpingography in cynomolgus monkeys. The animals were anesthesized, and a needle was manipulated through the cervical canal into the endometrial cavity for injection of contrast material. Difficulties in threading the needle through the canal were due to several blind pouches formed by folds in the cervical mucosa. The uterine lumen and both tubes could be visualized in over 75% of the cases. The study demonstrates that the hysterosalpingography technique can be performed satisfactorily in cynomolgus monkeys.
