introduction: morphology and ultra-structure of myoid and sertoli cells were studied in patients with non-obstructive azoospermia who were admitted to testicular sperm extraction (tese) and intracytoplasmic sperm injection (icsi), by transmission electron microscopy (tem). materials and methods: 12 biopsies of testicular tissues from patients with non-obstructive azoospermia referred to royan i...

The hypothesis to be tested was that abnormal sperm chromatin structure is related to disturbed spermatogenesis in patients with testicular cancer. After orchiectomy but before further treatment ("pretreatment"), semen samples from 39 patients with testicular cancer were analyzed for sperm concentration by light microscopy and by the sperm chromatin structure assay (SCSA). In 28 patients assess...

Testicular arteries are the branches of the abdominal aorta below the level of origin of renal arteries. They may originate at a higher or a lower level from the aorta. However, when they originate from some other artery, they become surgically significant, since the ligature of the main artery giving rise to the testicular artery might lead to testicular atrophy. The present report is about th...

Mixed testicular tumors are of great interest both clinically and pathologically. Being in most cases benign neoplasms, they sometimes give rise to metastases, some subjected malignant transformation, so that their timely recognition is particular value. In the pathological anatomical sense these neoplasms relation microscopic structure, often extremely complex histogenesis.

objective(s):leptin is a novel and interesting hormone for anyone trying to lose weight, but its effects on male gonad structure in longitudinal study is unknown. the present study was designed to explore morphometrical changes of mouse testicular tissue after long-term administration of leptin. materials and methods:thirty healthy mature male mice were randomly assigned to either control (n=15...

background: while young men are at higher risk of developing testicular cancer (tc), testicular-self examination (tse) is an easy, cost effectiveness method to early detection of this disease. the aim of the study was to investigate medical sciences student`s awareness, attitude and self-efficacy about tc and tse. methods: this cross-sectional study was carried out among full time young student...

objective(s) this investigation was conducted to evaluate the effects of diabetes on the structure and function of testicular tissue. materials and methods diabetes was induced in male adult rats by a single intraperitoneal injection of streptozotocin. body and testicular weight, hormonal analyses, histological and ultrastructural analyses were measured. results the body and testicular weights ...
