Background and purpose: Cyclophosphamide (Cyclo) is a common chemotherapy medicine that reduces male fertility. Various antioxidant agents have been used to reduce the side effects of chemotherapy medicines. Zinc oxide nano particles (nZno) have been introduced as a potent antioxidant. This study aimed at investigating the protective effects of nZno on testis tissue structure in Cyclo treated m...
The aim of this study was to evaluate the effect of broad bean on physical properties of testis and qualitative and quantitative characteristics of epididymal spermatozoa of the ramZell breed. The sixteen sexually matured rams weight approximately 29±1 kg were selected and randomly divided into four treatments and four replicates in a completely randomized design. The treatments included: 1) co...
Background & Aim: Ruta graveolens(R.G) has been used for sexual impotence in men and abortion in women. In this study the effect of aqueous extract of this plant has been investigated on testis tissue and spermatogenesis. Material and Methods: For this reason as an experimental research, animals were allocated to three groups as control which did not receive anything, vehicle which received...
The hypothesis of this experiment was that the various sources of dietary fat with different dietary ratios of polyunsaturated fatty acids (PUFAs) to saturated fatty acids (SFAs) would alter the reproduction parameters of mature rams. Twelve mature rams were randomly allotted to one of four dietary treatments in a completely randomized design. Dietary treatments were: 1) ration with 4% soybean ...
Dermoscopy is a handy tool originally used for evaluating pigmented lesions and melanoma. However, over the years, numerous indications have cropped up including its role in diagnosing infestations (entomodermoscopy).2 Dermoscopy combines light source and magnifying lens in such a way that it enables visualization of patterns not visible with clinical inspection alone.2 The evidence available r...
