To assess comparative 3fi-hydroxysteroid dehydrogenase-isomerase and I7fisteroid dehydrogenase activities in human fetal testis and adrenal, equal weights of adrenal and testicular tissue from the same fetuses were incubated with dehydroepiandrosterone or pregnenolone, under identical conditions. Tissues from five fetuses were investigated. The following products were isolated and quanti tated:...
Background Although oncologic testicular sperm extraction (onco-TESE) has been increasingly practiced, the evidence of onco-TESE performed in patients with testicular cancer is insufficient. Furthermore, in bilateral testicular cancer, accounting for 0.5%-1% of testicular cancers, onco-TESE is more challenging and has been insufficiently reported. Case presentation Here we report the case of ...
This study aims to provide the means for testicular dose estimation from radiotherapy for rectal cancer. Rectal irradiation was simulated on a humanoid phantom using a 6 MV photon beam. The effect of field size, distance from irradiated area, wedge introduction into lateral beams, tissue thickness along the beam axis and use of gonad shields on the testicular dose was examined. Testicular dose ...
background: acyclovir (acv), a synthetic purine nucleoside analogue, is known to be toxic to gonads. objective: the current study evaluated cytotoxicity of acv on histopathological changes in testis tissue and serum testosterone and lipid peroxidation concentrations of male rats. materials and methods: animals were divided into five groups. one group served as control and one group served as co...
Background and Objective: An increase in malondialdehyde and a decrease in the total antioxidant capacity associated with high blood glucose and insulin resistance in type 2 diabetes cause damage to the testicular tissue and structure. The aim of this study was to evaluate the effect of different aerobic training intensities on serum levels of malondialdehyde, total antioxidant capacity and tes...
Background: Atrazine (ATR) is used as an agriculture herbicide worldwide. It has been shown that ATR adversely affect the reproductive system in rodents. In this study we aimed to evaluate the impact of chronic exposure to Atrazine (ATR) on male testicular tissue, sperm parameters, serum level of total thiol molecules (TTM) and malodialdehyde (MDA) content of testes. Methods: To follow-up th...
