conclusions the inhibition of mini-puberty period in male rats was demonstrated to have an effect on their testicular function to some extent. results serum t and lh levels peaked at two hours after birth, while fsh peaked at hour 0, and bilateral testicular weight peaked at four hours after birth. the rats that underwent ether inhalation five minutes after birth had markedly reduced serum horm...

adenocarcinoma of the stomach was the leading cause of cancer-related death worldwide through most of the 20th century. usual presentations of gastric cancer include anorexia, epigastric pain or discomfort and weakness. rarely, patients present with unusual clinical manifestations. in this article, we report two cases with uncommon presentations of gastric adenocarcinoma. the first patient was ...

background: in radiation therapy, peripheral dose or the dose outside the radiotherapy field, is important when anatomical structures with very low dose tolerances are involved. one of these critical organs in pelvic irradiation is testis. the amount of radiation delivered to the testes in radiotherapy must be kept as small as possible, consistent with the limit dose of this organ. the threshol...

ischemia-reperfusion injury is a possible cause of testicular damage and infertility after testicular torsion and detorsion. the purpose of this study was to evaluate the effect of ghrelin on testicular ischemia-reperfusion damage. a total of 30 adult male rats were selected for the study and divided randomly into 3 groups, each containing 10 rats. animals in the testicular torsion and ghrelin ...

Mechanisms of testicular thermoregulation, the relationship of scrotal, testicular vascular cone (TVC), and testicular morphology with thermoregulatory capability, and their effects on semen quality and sperm production were studied in 20 Bos indicus, 28 crossbred, and 26 Bos taurus bulls. The ratio of testicular artery length and volume to testicular volume were larger (P<0.05) in B. indicus a...

anandamide is an endogenous ligand for cannabinoid receptors and has endothelial protective effect against ischemic preconditioning. the purpose of this study was to investigate the effects of cannabinoids on reperfusion injury due to testicular torsion-detorsion (t/d). a total of 36 adult male sprague-dawley rats were divided into 6 groups. testicular ischemia was achieved by twisting the righ...

BACKGROUND Inorganic arsenic is a major water pollutant and a known human carcinogen that has a suppressive influence on spermatogenesis and androgenesis in male reproductive system. However, the actual molecular events resulting in male reproductive dysfunctions from exposure to arsenic remain unclear. In this context, we evaluated the mode of action of chronic oral exposure of sodium arsenite...

BACKGROUND Although risk estimates for synchronous and metachronous contralateral testicular cancers vary widely, many clinicians recommend routine biopsy of the contralateral testis for patients diagnosed with unilateral testicular cancer. We evaluated the risk of contralateral testicular cancer and survival in a large population-based cohort of men diagnosed with testicular cancer before age ...
