PDF In the present study, sperm distribution in the genital tract of the bitch following artificial insemination AI in relation to the time of ovulation was investigated by histology, scanning electron microscopy SEM and flushing. Ovariohysterectomy was performed 24 h after AI. Half of the genital tract was divided into nine segments cervix, corpus uteri, caudal, middle and cranial uterine horn UTHutero—tubal junction UTJisthmus, ampulla and infundibulumwhich were processed for histology and SEM. The contralateral UTH and uterine tube UT were flushed, and several sperm characteristics were assessed.

A stud dog has many factors contributing to his potency, both in accepted and fresh chilled or frozen semen breedings, just as a bitch has many factors in her chance by conception over her lifetime. If a breeder wishes to expand his before her gene pool, either through cold or fresh chilled breeding, when a natural breeding is impossible, then the fertility of a stud dog is of prime importance. Unlike the bitch, which is born with as a lot of eggs as she will ever ovulate in her lifetime, a stud afflict is continually producing sperm. The all-purpose health as well as stress aim and other factors, all contribute en route for the fertility of a stud afflict at a particular point in age.

DOI: In this clinical study, the cog stimuli causing mating-induced uterine contractions were investigated in 64 bitches. Basal uterine contractions were present during oestrus after that a significant increase in the incidence of contractions was observed during accepted mating. Neither teasing with a manly nor stimulation of the vagina before cervix by vaginal or transcervical insemination TCI caused an increase in the frequency of uterine contractions. Increased contractions were however present after both vaginal and transcervical insemination when the antechamber was distended, and dorsal wall of the vaginal was manually stimulated.
