Report of a Case. A 23-year-old healthy man visited the emergency department with decreased vision in his left eye. His best-corrected visual acuities were 20/20 OD and light perception OS. There was a left afferent pupillary defect. Slitlamp and fundus examination results of the right eye were unremarkable. Dilated funduscopic examination of the left eye was limited due to a vitreous hemorrhag...

context to review and summarize the literature regarding the current status of postchemotherapy laparoscopic retroperitoneal lymph node dissection (pcl-rplnd) in patients with testicular germ cell tumor. evidence acquisition a comprehensive review of the english literature was performed using the pubmed database using the terms “laparoscopy” or “laparoscopic”, retroperitoneal lymph node dissect...

Spermatogenesis is a costly process that is expected to be under selection to maximise sperm quantity and quality. Testis size is often regarded as a proxy measure of sperm investment, implicitly overlooking the quantitative assessment of spermatogenesis. An enhanced understanding of testicular function, beyond testis size, may reveal further sexual traits involved in sperm quantity and quality...

INTRODUCTION AND OBJECTIVES Although standard surgical treatment of a testicular tumour is orchiectomy, use can be made of testis-sparing surgery in selected cases, based on tumour markers, tumour size, and histopathological findings. Our objective is to become acquainted with the indications of testis-sparing surgery as a treatment for the incidental finding of a palpable and non-palpable test...

Because it detects discrete changes in tissue density, ultrasound allows an early diagnosis of physiologic changes, especially when dealing with subclinical changes. aimed to evaluate the use quantitative analysis gray scale images ovine testicles as a method for testicular caused by heat stress. Testicles from ten were insulated and then evaluated regarding echogenicity, echotexture, anatomica...

Gonadotropin-releasing hormone (GnRH) is critical for the onset and maintenance of reproduction in vertebrates. The development of GnRH neurons is highly dependent on fibroblast growth factor (Fgf) signaling. Mice with a hypomorphic Fgf8 allele (Fgf8 Het) exhibited a ~50% reduction in GnRH neuron number at birth. Female Fgf8 Het mice were fertile but showed significantly delayed puberty. Howeve...

Arneja D. V., D. Chand, G. C. Georgie: Age influenced Variations in Plasma Cholesterol, Testicular Cholesterol and Testicular Ascorbic Acid of Prepubertal Turkeys (Meleagris gallopavo). Acta vet. Bmo, 50, 1981: 53-59. The blood plasma and testicular cholesterol and testicular ascorbic acid concentrations were determined in prepubertal male turkeys at different periods between 135 and 235 days o...

Adult extrarenal nephroblastoma is a very rare tumor. Nephroblastoma arising from primary testicular germ cell tumor is exceedingly rare. To our knowledge, only three cases have been reported in the English literature. We report a case of a 19-year-old man who presented with a large right testicle. Image studies showed a large retroperitoneal mass along with liver and lung metastases. Orchiecto...

Regressed (burnt-out) testicular germ cell tumors (TGCT) are rare clinical situations that are clinically difficult to recognize. This 43-year-old patient was admitted because of a suspicion of prostatic carcinoma, which eventually was followed by transrectal ultrasonography and a CT scan, both of which revealed a large retroperitoneal mass. Surgery showed extensive ureteral and vas deferens in...

The word “adenomatous hyperplasia of rete testis” (AHRT) was used by M. Nistal et Al. for the first time in an article about the cystic dysplasia of the testis (1976). AHRT is a benign lesion of the testis. The patient who came to our attention was studied with a testicular echo color Doppler that identified a solid, well circumscribed and hypoechoic mass of 4.5 x3.8mm as diameter, localized in...
