The present study is the first report of unilateral testicular hypoplasia in 3 of 15 (20%) Indian blackbuck antelopes (Antilope cervicapra). Interestingly, the condition was restricted to only the right testis in all cases. Cytogenetic analysis revealed chromosomal aneuploidy in the affected individuals which had a 34,XY1,der(13) karyotype with loss of the acrocentric (autosomal) Y2 and an aberrant chromosome 13. We further determined that the semen output and the circulating testosterone… Expand


Testicular hypoplasia in a boar with abnormal sex chromosome constitution (39 XXY).
A boar with testicular hypoplasia had 39 chromosomes. Giemsa banded preparations permitted unambiguous identification of an XXY sex chromosome constitution. Spermatogenic tissue was absent as in XExpand
Surgical exploration showed markedly hypoplastic intra-abdominal gonads, which demonstrated both testicular and uterine tissue on histologic examination, which resembles two human intersex syndromes: embryonic testicular regression syndrome and partial gonadal dysgenesis syndrome. Expand
An XXY sex-chromosome constitution in a dog with testicular hypoplasia and congenital heart disease.
A sterile male German shorthair pointer with testicular hypoplasia and a ventricular septal defect was found to have a 79, XXY chromosome constitution in peripheral-blood leukocytes, bone marrow and f
Heritable testicular hypoplasia in Nguni (Bos indicus) bulls: vascular characteristics and testosterone production.
The biased unilateral occurrence of heritable gonadal hypoplasia was investigated by examining the gross- and microanatomy of the testicular artery and vein, testicular blood flow and testicularExpand
Unilateral testicular hypoplasia in a white Fulani bull: case report.
The semen quality was poor and the seminiferous tubules of the left testis were devoid of spermatogenic elements. Expand
Male Pseudohermaphroditism in the Bowhead Whale, Balaena mysticetus
Findings suggest a failure of androgen expression consistent with the syndrome of complete testicular feminization reported in other species, and structural comparisons with normal male bowheads confirm abnormal development in the two affected whales. Expand
Testicular hypoplasia in a bull persistently infected with bovine diarrhoea virus.
A bull aged 16 months with bilateral testicular hypoplasia and azoospermia was persistently infected with bovine viral diarrhoea virus (BVDV). Viral antigen was detected in serum and semen by ELISA,Expand
Testicular histology of cryptorchid black-tailed deer (Odocoileus hemionus sitkensis) of Kodiak island, Alaska
It was concluded, that hypoplastic or cryptorchid testes cause male infertility but the production of testosterone in the less affected Leydig cells is sufficient to initiate and control the antler cycle. Expand
Chromosome studies in the mammalian subfamily Antilopinae
A taxonomy has been constructed which differs most markedly from the classical taxonomy in two aspects: the blackbuck, Antilope cervicapra, shows a strong karyotypic affinity to gazelles of the subgenus Nanger; Thomson's gazelle, Gazella thomsoni, lacks the numerous Robertsonian fusions and the X-autosome translocation common to other members of Gazella studied to date.

Abnormal Antler Growth Associated with Testicular Hypogonadism in Red Deer
The clinical and pathological changes seen in this deer were most consistent with congenital hypoplasia, but testicular atrophy was an alternative possibility for the etiology of their condition. Expand
