OBJECTIVE Laparoscopy has become one of the important diagnostic modalities of nonpalpable testis and has been developed and applied in the treatment of this disease. In the present study, we investigated the usefulness of laparoscopy in the diagnosis and treatment of nonpalpable testis. METHODS Laparoscopy was carried out under general anesthesia on 21 patients (23 testes) from October 1991 ...

Testis torsion in pediatric patients is a surgical emergency that requires immediate operative intervention. Heterogeneity, which has been associated with testis loss, is only grossly detected on grayscale ultrasound. To quantify the extent of heterogeneity associated with torsion, we employed a unique, noninvasive technique to determine Dynamic Range (DR) in ultrasound images, and then compare...

objective(s):cyclophosphamide (cp) toxicity on testis was hampered by squid ink polysaccharide (sip) via restoration of antioxidant ability in our previous investigations. this study investigated roles of nrf2/are signal pathway in testis of treated mice. materials and methods: male kunming mice were employed to undergo treatment with sip and/or cp. protein levels of nrf2, keap-1, histone deace...

THE EFFECT OF ALOE VERA HYDROALCOHOLIC EXTRACT ON SPERMATOGENESIS PARAMETERS AND HISTOLOGICAL CHANGES IN TESTIS RATS FED WITH A HIGH-FAT DIET

Protective and synergistic effects of vitamin E selenium against tissue oxidative damages induced by cypermethrin in the rat’s testis

background: the study of specific genes expressed in the testis is important to understanding testis development and function. spermatogenesis is an attractive model for the study of gene expression during germ cell differentiation. spermatogenesis associated-19 (spata-19) is a recently-identified important spermatogenesis-related gene specifically expressed in testis. its protein product is in...

The objective of this study was to determine the contribution of the scrotum, testes, and the testicular artery to scrotal/testicular thermoregulation in bulls at two ambient temperatures. Crossbred beef bulls, 1.5 years of age, were placed in controlled environment chambers at ambient temperatures of 15 degrees C (n = 5) or 25 degrees C (n = 6). The distal lateral aspects and entire ventral pa...

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...

splenogonadal fusion is a rare congenital malformation whereby the splenic tissue is found attached or surrounded by the testis, and presents in both continuous and discontinuous forms. splenogonadal fusion may be misinterpreted as a primary malignant testicular or an adenomatoid tumor. knowledge about the existence of such an entity is essential in order to preserve the testis during surgical ...
