Abstract: Gynecomastia is a benign enlargement of male breast tissue due to the proliferation of the ductal component. It can be physiological or pathological. Gynecomastia can be a sign for testicular tumors including sex-cord stromal tumors and germ cell tumors. Testicular physical examination in combination with testicular untrasonography and serum germ cell tumor markers when necessary in t...

The protective effect of thymoquinone (TQ) was investigated in rats exposed to testicular injury induced by sodium arsenite (10mg/kg/day, orally, for two days). TQ treatment (10mg/kg/day, intraperitoneal injection) was applied for five days, starting three day before arsenic administration. TQ significantly attenuated the arsenic-induced decreases of serum testosterone, and testicular reduced g...

INTRODUCTION Testicular torsion and detorsion causes reperfusion injury which damages the testicular tissue and affects the quality of sperm. Deterioration in the quality of sperm worldwide is the recent scenario and one of its reasons is testicular ischemic/ reperfusion (IR) injury. Therefore the present study aims at producing new drugs for the treatment of testicular IR injury. METHODS 42 ...

Background and Aims: Diabetes mellitus causes testicular damage by increasing oxidative stress and inflammation. In the present study, modulation of oxidative stress by pioglitazone, a synthetic ligand of peroxisome proliferator-activated receptor-γ, was examined in testis of streptozotocin-induced diabetic rats. Materials and Methods: Diabetes was induced by a single dose of streptozot...

Testicular sperm extraction is a common procedure used to find spermatogenic cells in men with nonobstructive azoospermia. The laboratory processing of biopsied testicular tissues needs to be performed meticulously to acquire a high yield of cells. In this study, the effectiveness of mincing the tissues after testicular biopsy was assessed using histological evaluation, as was the possible adve...

A new method is described for the enzymatic preparation of testicular tissue to obtain vital spermatozoa for ICSI. The tissue obtained from both testes by biopsy is studied by means of the semi-thin section method as well as being cryo-preserved. If spermatid formation is assured by semi-thin section histology, vital spermatozoa from the cryo-preserved portion of testicular tissue are enzymatic...

background: the current study aimed to evaluate the effects of phosalone (pln) as an organophosphate (op) compound on testicular tissue, hormonal alterations and embryo development in rats. materials and methods: in this experimental study, we divided 18 mature wistar rats into three groups-control, control-sham and test (n=6 per group). animals in the test group received one-fourth the lethal ...
