in this investigation, diabetes was induced in adult male sprague-dawley rats by single intraperitoneal injection of streptozotocin (stz) at 45 mg kg-1 of body weight. a group comprised of 8 diabetic rats was treated with metformin at 100 mg kg-1 of body weight for reducing the elevated blood glucose level. the results revealed that, in the untreated diabetic rats, the body and testicular weigh...

Prenatal caffeine exposure adversely affects the development of the reproductive organs of male rat offspring. Thus, it is conceivable that peripubertal caffeine exposure would also influence physiologic gonadal changes and function during this critical period for sexual maturation. This study investigated the impact of high doses of caffeine on the testes of prepubertal male rats. A total of 4...

Granulosa cell tumor (GST) is a sex-cord/stromal neoplasm of the gonads, more commonly arising in the ovaries, while approximately 80 cases have been reported in the testes. Out of these, 30 cases were of the adult type, while the remainder 50 cases were of the juvenile type. The latter mostly concerned infants and followed a benign course. However, the adult type testicular GCTs may be potenti...

Background: Methylphenidate (MPH), Ritalin, is one of the most common medications. The administration of Ritalin leads to increase of the activity of central nervous system. Ritalin may be used for maintaining alertness and improving of attention which may lead to increase of the risk of substance abuse in some cases. There is a little data about the effects of long term treatment with Methylph...

The effects of ethanol extract of Spondias mombin leaf on male rats’ fertility were investigated. The extract was orally administered with 250 and 500mg/kg doses for 8 weeks. There was significant decrease in testicular and epididymal weight in the treated animals compared to the control. Histomorphology of the testis showed distortion in the arrangement of seminiferous tubules, loose germinal ...
