Background: Methamphetamine (mAMP) as a recreational drug has devastating effects on the central nervous system (CNS). Several studies have shown that mAMP has inhibitory effects on oogenesis and spermatogenesis, and causes impaired fertility. This study designed to investigate the effect of mAM Padministration on histological changes and spermatogenesis indices in the testis of adult male rats...

reports indicate that one of the causes of harmful to the genital system, especially the testes stress. stress could be created secondarily after some pathological conditions such as neurological diseases or environmental factors. one of the causes of stress could be scary voices, such as cat voice for mice. in this study we aimed to investigate the testes parameters in the animals that were ex...

By combining two of the morphological characteristics of gastric cancer, the degree of differentiation of the glandular tubules and the amount of mucus in the cytoplasm, the histological type of the gastric carcinoma was categorised into four groups. Group I: tubular differentiation--well; mucus in cytoplasm--poor; group II: tubular differentiation--well; mucus in cytoplasm--rich; group III: tu...

introduction: cyclophosphamide (cp) is used for the treatment of various cancers. in spite of its therapeutic importance, a wide range of adverse effects such as reproductive toxicity has been observed following the administration of this drug in human and experimental animals. in the current study, we have investigated the adverse effects of cp on morphology and histology of testis rats. metho...

Tubular apocrine adenoma, the variant of papillary tubulopapillary hidradenoma, is a rare well-circumscribed, intradermal benign tumor, with tubular structures showing differentiation. It usually presents as slow-growing well-circumscribed nodule. The most common site involvement scalp, although it has also been reported to occur at other sites like face, neck, axilla, trunk, upper and lower ex...

background: diabetes is the most common endocrine disease. it has adverse effects on male reproductive function. royal jelly (rj) has antioxidant and anti-diabetic effects and show protective effects against diabetes. objective: this study was conducted to evaluate the effect of rj on histopathological alterations of the testicular tissue in streptozotocin (stz)-induced diabetic rats. materials...

Background: Isoniazid is an important drug in first line of treating the tuberculosis disease. This drug can lead to damages in different parts of the body such as liver and testis. Lactobacillus acidophilus and Bifidobacterium are the probiotics that have the important innate property that inhibit from passing of Isoniazid into the blood-testis-barrier. In point of spermatogenesis indexes whic...
