Transport of spermatozoa in the reproductive tract of the bitch: observations through uterine fistula.

Abstract: Using unilateral uterine fistulas, the time required for spermatozoa to reach the end of the fistula after natural mating, artificial insemination (AI) in a normal standing posture (NP), and AI standing on the head (SH) was investigated in each of three stages of estrus. Conceptivity in these bitches was also investigated. Five experimental bitches were tested during a total of 8 estrous periods. The results are as follows; the time required for spermatozoa to reach the end of the fistula was almost the same in the early and middle stages, i.e., 30 sec to 1 min after natural mating and SH and less than 2 min for half the bitches in NP, although no intrauterine transport could be observed in the other half. In most cases of mating during the late stage no spermatozoa were found after any of the 3 methods of insemination. Five animals became pregnant in these experiments, but the other three failed to conceive. The implantation of fertilized ova occurred also in the fistulated uterine horn in all cases of pregnancy.

[Endometriosis of the bladder and vesico-uterine fistula as complications of cesarean section].

Abstract: The authors described a case of endometriosis of the urinary bladder and periodically active uterovesical fistula, following Cesarean section. Clinical symptoms of endometriosis dominated and were the reason for the patient's visiting the physician. Clinical diagnosis was made by cystoscopy during menstruation. Surgical resection of the focus of endometriosis of the bladder and uterus during menstruation led to permanent recovery.
