unilateral orchidectomy (uo) is required when further breeding potential is important. it is sometimes necessary to remove a single testis in a matured stallion for therapeutic reasons. in this study, twelve donkeys were used to evaluate three techniques of unilateral castration, histological and morphological changes on the remaining testis. results of the study showed that each of the surgica...

background: long term alcohol use has been implicated in men with sexual disorders including suppression of testosterone levels as well as testicular morphological changes. objective: this research investigated the ability of telfairia occidentalis (t.o.) to attenuate the damaging effects of alcohol on the testicular parameters. materials and methods: thirty male sprague-dawley rats, 170-190 gr...

in order to study the anatomy and histology of the testis and epididymis of caspian miniature horse, five adult stallions were used. routine anatomical and histological methods were used. anatomical study indicated that there were no differences between the testis and epididymis of the caspian miniature horse with the ordinary horse, except with the smaller sizes. the epididymis is attached to ...

quantitative histology of the descended testis of unilateral cryptorchid bucks was compared with testis of normal bucks to evaluate the reproductive potentials of the scrotal testis in unilateral cryptorchids, using light microscopy techniques. the contralateral scrotal testes of the unilateral cryptorchids and the testes of the normal bucks contained profiles of seminiferous epithelium and eac...

OBJECTIVE To investigate the effects of continued hypoxia on postnatal development of the rat testis. DESIGN Wistar rats were exposed to simulated hypoxia from birth to postnatal day (PND) 45. Testosterone (T) in the plasma and the testis was measured in rats at PND 3, 7, 14, 21, 28, 35 and 45 respectively. Testis histology and cellular ultrastructure were studied. RESULTS a) Hypoxia induce...

Quantitative histology of the descended testis of unilateral cryptorchid bucks was compared with testis of normal bucks to evaluate the reproductive potentials of the scrotal testis in unilateral cryptorchids, using light microscopy techniques. The contralateral scrotal testes of the unilateral cryptorchids and the testes of the normal bucks contained profiles of seminiferous epithelium and eac...

Pesticides are known to affect the testis in fishes and cause cytomorphological changes or gross physiological alterations due to changes in its histology, retard gonadotrophic secretions thereby causing regression of the gonads. Light and ultrastructural studies were made on control and fenthion treated testis, interstitial gland and sperms of G. giuris during spawning phase after exposing the...

Objective The lipid composition of a mammal’s spermatozoa and seminal plasma vary in both structure and function. Evidence exists to suggest that dietary supplementation with the appropriate polyunsaturated fatty acids (PUFAs) affects spermatogenesis, semen quality and sperm motility. Therefore, this study has been conducted to evaluate the correlations between serum lipid profile and histologi...

OBJECTIVE To discuss the relationship between testicular microlithiasis and testis tumors in children and to consider the chances of testis preserving surgery in specific cases. CASE DESCRIPTION Pre-adolescent presenting testicular microlithiasis and a larger left testis, corresponding to a cystic testicular tumor. The tumor was excised, with ipsilateral testis preservation. Histology diagnos...

The current study aimed to detect specific types of ADAM proteins in the bovine sperm. Histology tissue male reproduction was involved with testis, head, body, and tail epididymis. Results showed that testis composed parenchyma contained seminiferous tubules which are surrounded by two layers externally tunica vaginalis internally albuginea. PAS positive lumen, epithelium body epididymis, Where...
