We sought to determine whether ambient temperature (T(a)) affects gonadal function by altering the rate at which circadian rhythms entrain to short day lengths. Syrian hamsters were housed in cages where they received 14 h of light per day ("long days," 14L) at 22 degrees C. Hamsters were then transferred to cages to receive 10 h of light per day ("short days," 10L) and kept at 5, 22, or 28 deg...

A hidrocele testicular consiste no acúmulo anormal de líquido na túnica vaginal, geralmente relacionada à lesão ou inflamação escroto. Este trabalho tem como objetivo relatar a utilização do exame ultrassonográfico e o histopatológico para diagnóstico em suíno. Um cachaço apresentou aumento volume testicular, com edema enrijecimento dos testículos, sem sinais algesia. No havia regiões delimitad...

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 review of t...

Physical agents such as ultraviolet or ionizing radiation and repetitive trauma have been related to the causation of cancer in humans. Much less clear is the association between exposure to radiofrequency, such as radar and microwave radiation to the development of cancer. Sporadic case reports and small series suggest that this type of radiation might lead to cancer or contribute to its evolu...

Male hypogonadism is a condition characterized by decreased testosterone production and sperm quality or production. This can be the result of primary testicular failure or secondary testicular failure due to pituitary or hypothalamic disorders. Symptoms of hypogonadism include erectile dysfunction, decreased libido, and regression or absence of secondary sexual characteristics. Total testoster...

We report a five-month-old boy who was referred to the hospital with a presumptive diagnosis of hydrocele of the cord. Ultrasonography revealed a cystic mass within the left testis. A complete removal of the cystic mass was done. Histopathological diagnosis was simple cyst of the testis. This rare lesion should be considered in the differential diagnosis of cystic testicular lesions in infancy....

background: after improvements in various cancer treatments, life expectancy has been raised, but success in treatment causes loss of fertility in many of the survived young men. cryopreservation of immature testicular tissues or cells introduced as the only way to preserve fertility. however, freezing has some harmful effects. melatonin, a pineal gland hormone, has receptors in reproductive sy...

BACKGROUND The risk of losing the testis is an ever present threat in patients with testicular torsion, who delay before presenting to the surgeon. A retrospective study was carried out to audit patients with acute scrotal pain who came to the Trans Ekulu Hospital Enugu, the promptness of offering them surgical treatment and the results. MATERIALS AND METHODS Patients operated upon for suspec...

The aim of this study was to evaluate the possible development of histological abnormalities such as fibrosis and microcalcifications after sperm retrieval in a ram model. Fourteen testicles in nine rams were exposed to open biopsy, multiple TESAs, or TESE, and the remaining four testicles were left unoperated on as controls. Three months after sperm retrieval, the testicles were removed, fixed...

OBJECTIVE To report a case of a Segmental testicular infarction (STI) simulating a testicular tumour and to discuss the importance of the excisional frozen biopsy. METHODS We present the case of a patient with STI mimicking a testicular tumour. RESULTS The patient was treated with partial orchiectomy after excisional frozen biopsy. CONCLUSIONS The excisional frozen biopsy in testicular ma...
