Two American Paint Horses, a 3-year-old nulliparous mare and a 7-year-old primiparous mare, presented for recent infertility and a pre-breeding examination, respectively. Examination of the internal reproductive tract of both mares using transrectal palpation and ultrasonography revealed the presence of the cervix, uterine body, left uterine horn and bilateral ovaries. The right uterine horn could neither be palpated nor imaged. The clinical diagnosis of uterus unicornis in one mare was confirmed at necropsy, which revealed combined aplasia of the right uterine horn and oviduct.
[Show abstract][Hide abstract] ABSTRACT: The authors describe two cases of cervical hypoplasia in jennets, detected during the gynaecological evaluation of two purebred females of the Portuguese donkey breed Asinina de Miranda. These jennets aged 10 and 15 years were referred for consultation by the local breeders association because of infertility detected during an artificial breeding programme. In both jennets the cervix was small, shorter than the usual and closed. In one of the females, outflow of semen during artificial insemination was reported. Clinical and ultrasonographic evaluation of the genital tract demonstrated that both ovaries were normally sized in both animals and presenting structures suggestive of regular ovarian activity. In one of the jennets, a small amount of air in the uterus was evidenced. In the other, signs indicative of atresia of the cervical canal were found. Vaginal examination showed that the cervix was reduced in size and shallowed in both animals. A diagnosis of congenital cervical hypoplasia was made in both cases and the animals were excluded from reproduction.
[Show abstract][Hide abstract] ABSTRACT: A study was conducted between July 2010 to June 2011 in the Monkey Sterilization Centre, Gopalpur, Himachal Pradesh, India to assess the prevalence of reproductive disorders by laparoscopic examination of the genitalia of female rhesus macaques. The animals were captured from different locations in the state using a cage trapping method. A total of 720 female rhesus macaques underwent laparo-scopic examination of their reproductive tracts. A total of 63 cases were found to have reproductive abnormalities. Out of these 63 cases, the most common abnormalities report-ed were ovarian cyst 3.05% (n=22), ovarian tumor 1.66% (n=12), uterine tumor 1.25% (n=9), uterine edema 0.97% (n=7), uterine rupture 0.83% (n=6), ectopic pregnancy 0.69% (n=5), unicornis or acornis 0.28% (n=2). The highest number of cases of uter-ine abnormalities was recorded in the 12-16 year old age group (33.33%), followed by 8-12 year olds (25.39%), 16-20 year olds (22.22%), then 4-8 year olds (15.87%) and 0-4 year olds (3.17%). Of the 63 animals that showed geni-tal abnormalities, only 52 were found to be pregnant during the breeding season from November to March in the 5-20 year old age group, while 11 animals were not pregnant; a pregnancy rate of 82.53% (52 of 63) of the female rhesus macaques with reproductive abnormalities.
