A study was conducted to evaluate the effect of supplementing different levels of Leucaena leucocephala leaves on reproductive capacity and growth of male highland sheep (Arsi type) in Debre Zeit Research Centre. Animals were randomly allotted to one of five experimental rations. In treatment 1 (NS) animals were allowed to feed only on chickpea haulm. Treatments 2 (L100), 3 (L200) and 4 (L300) ...

Fifty-two Holstein bulls were castrated at 12, 16, 20, 24, 28 or 32 weeks to (1) determine whether testicular development is influenced by season of birth (April or October) and (2) examine quantitatively the establishment of spermatogenesis. Season of birth (spring or fall) did not influence (P less than .05) either testis weight at castration or the establishment of spermatogenesis. With age ...

This case is the first report of a bacteriologically proven testicular abscess in a child caused by Salmonella paratyphi 'A' in Pakistan that clinically simulates a testicular tumour. The case also emphasises that a course of 2 weeks antibiotic is sufficient for testicular abscess if complete surgical debridement is done.

The objective of this study was to determine the effect of dietary energy, breed (British vs Continental x British crosses), and their interactions on scrotal surface temperature (SST), seminal quality, and sperm production in bulls. This experiment, replicated over 2 yr, included 72 Angus, Angus x Simmental, or Hereford x Simmental bulls fed either a moderate- (100% forage) or high-energy (80%...

the testicular torsion which is typically seen in prepuberty is very rare in the early neonatal period; prenatal diagnosis is difficult. herein, we report a five day-old male neonate with swelling and erythema of the right scrotum.  following doppler ultrasound suggestive of testicular torsion, surgical exploration was undertaken. there was gangrene of the right testis with discoloration and ne...

Alternative pre-mRNA splicing (AS) is a key molecular event that allows for protein diversity and plays important roles in development and disease. AS regulations during spermatogenesis and AS aetiology in testicular tumorigenesis have not yet to be characterized. By genome-wide analysis, here we describe alternative splicing features that distinguish distinctive patterns of AS among human test...

Hormone-sensitive lipase (HSL, Lipe, E.C.3.1.1.3) is a multifunctional fatty acyl esterase that is essential for male fertility and spermatogenesis and that also plays important roles in the function of adipocytes, pancreatic beta-cells, and adrenal cortical cells. Gene-targeted HSL-deficient (HSL-/-) male mice are infertile, have a 2-fold reduction in testicular mass, a 2-fold elevation of the...

UNLABELLED We investigated whether or not surgical strategy has an impact on the risk of invasive testicular neoplasia in cases of cryptorchidism. We made a database study of the incidence of testicular neoplasia at surgery for cryptorchidism in childhood, and evaluated if such abnormalities were found in special categories of patients, and also of the incidence of testicular neoplasia after or...

OBJECTIVE The purpose of this study was to assess the role of MRI in the preoperative characterization and local staging of testicular neoplasms. SUBJECTS AND METHODS MRI was performed on 33 patients referred because a testicular mass had been detected clinically and sonographically. Both T1- and T2-weighted sequences were performed with a 1.5-T MRI unit. Gadolinium chelate was administered I...
