One of the rarest varieties of intrascrotal neoplasm is a tumor composed of striated muscle. Only a few cases have been published and most of these appear as isolated reports in the older foreign literature. In many cases, the tumor was closely connected with the testicle, but it was difficult to determine whether it arose from the testis or from the adjacent tissue. Rokitansky in 1849 describe...

Background: Ciprofloxacin was shown to have cytotoxic effects on testicular germ cells. Its mechanism of cytotoxic action is not fully understood. To investigate the possibility of the involvement of an oxidative stress induction in this mechanism, total antioxidant power (TAOP) in the testis was evaluated. Materials and Methods: A number of twenty four mature male NMRI mice were used.The anima...

The aim of the current study was to investigate the histological and histochemical characteristics of large and small intestines of sea snake, Hydrophis cyanocinctus. Six adult sea snakes were collected from Minab beaches, located near the sea of Oman, in November, euthanized with chloroform, dissected and alimentary canal removed, tissues preparaed for sectioning and staining with Hematoxylin ...

Objectives: Benzene is an aromatic hydrocarbon and a colorless odorous liquid. It used in the production of plastics, detergents, pesticides, other chemicals. Serious deterioration seen sperm men who are exposed to hydrocarbons such as ethyl benzene, toluene, xylene also solvents found paints, lacquers, adhesive-like substances their professions. The aim this study examine possible effects benz...

In contrast to mouse germ cell-derived pluripotent stem cells, the pluripotent state of human testis-derived embryonic stem cell (ESC)-like that spontaneously arise in primary testicular cell cultures remains controversial. Recent studies have shown that these cells closely resemble multipotent mesenchymal stem cells (MSCs), raising the question of their origin and designating these cell popula...

Granulosa cell tumors can be classified into juvenile and adult types and more commonly occur in ovaries. Adult testicular granulosa cell tumors are extremely rare and only 29 cases of adult type have previously been reported. We report here a 28-year old Caucasian man with a left testicular adult type granulosa cell tumor. The tumor measured 2.6×2.6×2.5 cm and was mitotically active (10/10 HPF...

In 13 and 14-day old fetal rat ovaries maintained 3 to 10 days in organ culture, purified bovine anti-Müllerian hormone (AMH) (1.5 to 3 micrograms/ml) induced a characteristic freemartin effect. Gonadal volume and germ cell number were significantly reduced, compared to control ovaries cultured in anhormonal medium, and epithelial cells with large clear cytoplasm linked by interdigitations diff...

Effect of oral administration of aqueous leaf extract of Kalmegh (Andrographis paniculata) (250 mg/kg body weight/day) on the male reproductive organs of the wild Indian house rat (Rattus rattus) was investigated and its activity was noticed at 30th and 45th days of post treated animals. The treatment had no severe effect on body weight and the reproductive organs weight of rats. In treated rat...

Background: Doxorubicin (DOX), a widely used antineoplastic compound, is associated with testicular damage and infertility. In this study, we intended to determine the possible preventive effects of simvastatin (SIM), a lipid lowering agent with antioxidant and anti-inflammatory activities, on testicular morphometric-stereological changes due to DOX treatment in mice. Materials and Methods: Mal...
