Transervical insemination is a method in which semen is deposited directly into the uterus. This is done with the use of an endoscope. A catheter is attached to the endoscope allowing it to be able to be passed through the cervix into the uterus. With the use of a video camera it is possible for both the veterinarian and the owner of the bitch to watch the insemination.
During a natural mating, the dog’s semen is deposited in the vagina of the bitch. From this point the sperm cells have to travel to the cervix and also pass through the cervix. Once in the uterus the sperm cells are able to come into contact with the ovulating follicle cells released by the bitch. A long journey in which few sperm cells survive.
Transcervical insemination is a method in which the semen is transferred immediately into the uterus, thereby eliminating this long journey. It is an alternative in comparison to that of the regular artificial insemination in which the semen is deposited in front of the cervix.
