Livestock farmers may need a reference range of testicular sizes and sperm reserves to ascertain the reproductive efficiency male. However, information on camel morphometry gonadal reserve in semi-arid Nigeria is scanty. This study was designed provide extragonadal camels Sahel region Nigeria. Testes 15 mature healthy were obtained after slaughter from Maiduguri central abattoir. Scrotal circum...

because of continuous changing of anatomy, function and metabolism of the human brain, age- related change is a major risk factor in most prevalent neurodegenerative diseases, including parkinsons and huntingtons disease. therefore, knowing patterns of age-related atrophy of brain tissue can identify causes and possible role of diseases in decreasing brain function with age. the aim of this stu...

for this study the jejuni of 50 adult (2-4 years), apparently healthy iranian river buffaloes were collectedfrom the abattoir for gross morphology, histomorphology, and histomorphometry. our statistical analysisrevealed that, there are significant (p

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...

Cryptorchidism, the failure of one or both testes to descend into the scrotum prenatally, occurs in 2.4%-5% of newborns. Many of these testes will descend spontaneously shortly after birth, but ~23% will remain undescended unless surgery is performed. Bilaterally cryptorchid men have a six times greater risk of being infertile when compared with unilaterally cryptorchid men and the general male...

To develop techniques for spermatogonial transplantation in bulls, it is essential to have an effective bioassay procedure to evaluate the transplantation efficiency of spermatogonial stem cell collection, purification, and culture techniques. The objective of the present study was to develop a mouse bioassay model to evaluate transplantation efficiency of fresh and cultured bovine germ cells. ...
