Executive Summary The outputs from mathematical and statistical models can be influenced by uncertainty in the estimates of the parameters used (known as parameter uncertainty) and to the methods and assumptions used to construct and link parameters in a model (known as structural uncertainty). Sensitivity analysis was applied to the current bigeye stock assessment to ascertain the influence of...

The purpose of this study was to determine the effects of diabetes mellitus and insulin resistance on semen parameters, histology of reproductive organs and serum concentrations of testosterone and luteinizing hormone (LH). Male Sprague-Dawley rats weighing 180 - 200g were made diabetic by intravenous injection of alloxan (40 mg/kg): and insulin resistant by chronic fructose feeding (25% fructo...

Understanding how variation in reproductive success is related to demography is a critical component in understanding the life history of an organism. Parentage analysis using molecular markers can be used to estimate the reproductive success of different groups of individuals in natural populations. Previous models have been developed for cases where offspring are random samples from the popul...

Chlorpyrifos is one of the mostly used organophosphates insecticides, has a major toxic effect in mammalian rat’s reproductive system. The ancient Indian herbal formulation, Emblica offcinalis plays a major role to subvert many diseases in human body. Through a preliminary study, we have tried to establish the ameliorative properties of Emblica offcinalis with respect to reproductive rejuvenati...

Objective(s): Exposure to electromagnetic fields (EMF) emitted from mobile phones may cause a deleterious effect on human health and may affect the male reproductive system. Crocin, a carotenoid isolated from Crocus Sativus L. (Saffron), is a phar‌macologically active component of saffron. So, this study was conducted to investigate the protective effect of crocin on t...

The aim of the present study was to investigate the effects of long-term grape juice concentrate (GJC) consumption, in two dosages, on the reproductive parameters of cadmium-exposed male rats. The effects of the concentrate on body mass gain, plasma testosterone levels, reproductive organ weights, daily sperm production, sperm morphology, testis histopathological and histomorphometrical paramet...

Sphaerothecum destruens is an obligate intracellular parasite with the potential to cause high mortalities and spawning inhibition in the endangered cyprinid Leucaspius delineatus. We investigated the influence of L. delineatus's reproductive state on the prevalence and infection level of S. destruens. A novel real time quantitative polymerarse chain reaction (qPCR) was developed to determine S...
