BACKGROUND The xenografting of pre-pubertal human testicular tissue to an immunodeficient mouse is a theoretical strategy for restoring fertility in childhood cancer patients, while circumventing the risk of malignant recurrence. This study aimed at comparing the grafting of pre-pubertal and adult murine testicular tissue, as well as that of human adult testicular tissue, to two immunodeficient...

Objective To investigate effects of cryopreservation on changes of the ultrastructure of human testicular sperm and evaluate the efficacy of cryopreserving testicular tissue as a source of sperm for assisted reproduction. Methods Testicular biopsy tissues were obtained from infertile patients (n=12) with obstructive azoospermia and cryopreserved. Testicular sperm motility was observed after in ...

testicular cancer is one of the commonest cancers in men of working age, and is increasing in incidence in europe and north america. one suggested mechanism of causation is that there is impaired differentiation of germ cells in the pre- or perinatal period, followed by malignant transformation in later life, possibly by a hormonal mechanism. endocrine disrupting chemicals (edcs) have been a ma...

Testicular torsion is a well known urological emergency most common in the paediatric population. However, testicular can be complete, partial or intermittent. Intermittent rare adults and difficult to diagnose. We present case on intermittent 35 year old man that was initially misdiagnosed but later diagnosed by Spectral Doppler ultrasound.

Polycyclic aromatic hydrocarbons (PAHs), like benzo[a]pyrene (BaP), are ubiquitous environmental pollutants formed by the incomplete combustion of organic materials. The tripeptide glutathione (GSH) is a major antioxidant and is important in detoxification of PAH metabolites. Mice null for the modifier subunit of glutamate cysteine ligase (Gclm), the rate-limiting enzyme in GSH synthesis, have ...

Testicular scintigraphy has been well validated in the evaluation of patients with suspected testicular torsion and provides an accurate evaluation of testicular perfusion at the lime of imaging. However, the presence of normal or increased perfusion to the testis does not definitively exclude the necessity for surgical intervention. A case of intermittent testicular torsion, with a revie...

BACKGROUND Testicular calculus is an extremely rare case with unknown etiology and pathogenesis. To our knowledge, here we report the third case of testicular calculus. A 31-year-old man was admitted to our clinic with painful solid mass in left testis. After diagnostic work-up for a possible testicular tumour, he underwent inguinal orchiectomy and histopathologic examination showed a testicula...

Testicular torsion is one of the main causes of acute scrotum and may result in permanent damage of the testicular tissue. Color Doppler imaging has been frequently used in the diagnosis of testicular torsion and posttreatment follow-up period of the disease. There are some studies reporting the value and usefulness of diffusion-weighted imaging in the diagnosis of testicular torsion. However, ...

❏ A. Most cases of testicular cancer are discovered during the clinical examination. ❏ B. Testicular cancer is the most common type of cancer in men older than 50 years. ❏ C. Testicular cancer is common compared with other types of cancer. ❏ D. In most cases, testicular cancer is managed surgically; treatment also may include radiation therapy or chemotherapy. ❏ E. Less than 40 percent of newly...

Individuals involved in sports are at risk for sustaining various injuries. In addition to musculoskeletal complaints, male athletes are at risk of incurring testicular injuries. These issues can range from an acute emergency such as testicular torsion to indolent testicular tumors. In contrast, epididymitis can present in stages. Presentation and management of testicular complaints can vary de...
