Abstract
Natural mating in the dog is done by a special mechanism the ejaculated semen being transported directly from the vagina to the uterus depend on swelling and retention of the penis in the vagina, such mechanism defend backflow of semen. This trial was undertaken on transport the liquid (IODAMIDE MEGLUMIN) into the uterus of the estrous bitches. A balloon-like artificial penis made with latex rubber (Figs. 2, 3)was inserted into the vagina. Then adequate volume of air was infused into the artificial penis with a syringe through the tube for expansion. This prevents prolapse of the rubber penis by expansion of the rub- bercoital lock. Then about 10 ml of the liquid was infused through the other tube. And 5 minutes later, most of the liquid had been observed in the uterine horns by X-ray photograph (Fig.4) Hereafter, this method will be compared with the intravaginal insemination method elevating the hindquarters of the estrous bitch.
