Background: The male antifertility activity of Gossypol, the active ingredient of cotton seed, inspired the idea for development of an agent with male contraceptive activity. The result of subsequent studies lead to the discovery of several class of compounds with antifertility activity. In this study the antifertility activity of iso-Propyl and iso-Butyl derivatives of dihydropridine were ev...
Fecundity of Shah-Koolee in the Sefidrood river, which is one of the economic and popular fishes in northern part of Iran, was studied. From April to August 2000, 539 Shah-Koolee fishes were caught at the specific station in the Sefidrood river from the sea shore to Kisum.

The paper focuses on some of the biological characteristics of golden grey mullet, Liza aurata in Iranian waters of the Caspian Sea. Samples of commercial catch of mullet obtained by means of beach seine fishing cooperatives along the Iranian coasts of Caspian Sea (2007-2008) as monthly interval. Samples subjected to biometric measurement to specify their biological characteristics. The male/f...
Background and Aims: There is concern that leached components from dental composites may cause adverse changes in the reproductive health. This study aimed to assess the effects of leached components from a hybrid resin composite on the reproductive system of male mice.Materials and Methods: In the present animal study, twenty adult Syrian male mice were divided into two groups of 10 mice each....
The ultrastructure of testicular cells of adult male African clawed frogs (Xenopus laevis) exposed to either estradiol (0.1 microg/L) or 2-chloro-4-ethylamino-6-isopropyl-amino-s-triazine (atrazine; 10 or 100 microg/L) was examined by electron microscopy and compared to plasma concentrations of the steroid hormones, testosterone (T) and estradiol (E2), testicular aromatase activity and gonad gr...
This study examined the effect of underground water on reproductionand growth-related hormones in blue gourami males under non-reproductive and reproductive conditions. An increase in the percentage of males building nests under the highest percentage of underground water were compared to fish that maintained a lower percentage of underground water in the first two days. The % Gonado-somatic in...
The main focus of the study was to assess effect lipid levels on reproduction female orange mud crab, Scylla olivacea. Four isonitrogenous feed (~420 g/kg) were formulated with different percentages: T 1 = 60 g / kg , id="M2"> 2<...
Phthalates, plasticizing chemicals, are top-rated environmental contaminants. Diethyl phthalate (DEP), a chief member of this family, was declared potent endocrine disruptor and carcinogen in animals humans. The current study designed to explore the probable reproductive damage induced by DEP therapeutic efficacy raw honey male albino mice. Four-week-old 50 mice were randomized equally five gro...
