Testicular tumors are relatively rare and comprise 1% of all male cancers worldwide with peak prevalence in the age group 15-35 years. lesions have a varied histomorphological spectrum largely categorized as non-neoplastic neoplastic lesions. To study incidence testicular lesions, to including well determine age-wise distribution, laterality clinical presentation The present is an observational...

ناباروری( infertility) یکی از جدی ترین مشکلات اجتماعی در کشورهای پیشرفته است.تقریبا15% از زوج ها با موارد مختلف ناباروری مواجه میشوندو علت 50% از ناباروری این زوج ها مربوط به فاکتورهای وابسته به مردان است. بر اساس تحقیقات موجود علل ناباروری در مردان بیشتر در طی فرایند اسپرماتوژنز ( spermatogenesis) صورت می گیرد. تغییرات ژنتیکی در ژنهایی که در این فرایند درگیر هستند نقش مهمی در اختلالات روند اس...

In contrast to most metastatic cancers, testicular germ cell tumors are cured in more than 80% of patients using cisplatin-based combination chemotherapy. Testis tumor cells in vitro retain their sensitivity to chemotherapeutic drugs, radiation, and other stresses, such as heat shock. Having shown that this is associated with low constitutive levels of heat shock protein (HSP) 27, we determined...

PURPOSE Neoplastic cells often aberrantly express normal testicular proteins. Because these proteins have a very restricted normal tissue expression, they may be suitable targets for immunotherapy. SLLP1 is an intra-acrosomal, nonbacteriolytic, c lysozyme-like protein recently isolated from human spermatozoa. In this study, we determined whether SLLP1 is a novel cancer-testis antigen in hematol...

In contrast to most metastatic cancers, testicular germ cell tumors are cured in more than 80% of patients using cisplatin-based combination chemotherapy. Testis tumor cells in vitro retain their sensitivity to diemotherapeutic drugs, radiation, and other stresses, such as heat shock. Having shown that this is associated with low constitutive levels of heat shock protein (HSP) 27, we determined...

Testicular cancer is cancer that develops in the testicles, a part of the male reproductive system. Although testicular cancer can be derived from any cell type found in the testicles, more than 95% of testicular cancers are germ cell tumors. Most of the remaining 5% are sex cord-gonadal stromal tumors derived from Leydig cells or Sertoli cells. Over man's lifetime, his risk of testicular cance...

OBJECTIVE To prospectively determine the prevalence of testicular microlithiasis in symptomatic patients who were referred for scrotal ultrasound examination and to evaluate the possible association of testicular microlithiasis with testicular cancer and other conditions such as cryptorchidism or history of ascending testis. MATERIALS AND METHODS 391 men who were referred to our institutions ...
