متن کاملEffects of Pesticides on Male Reproductive Functions
Exposure to pesticides could be one of the contributing cause to the falling sperm counts and rising levels of male infertility. Adverse effects of pesticides in the environment first received widespread attention in the 1960s. However, only recently it has been postulated that long term, low exposure of these chemicals are increasingly linked to human health effects such as immuno-suppression,...
متن کاملEffects of carbamazepine on male reproductive hormones
Background :Reproductive endocrine disorders and sexual dysfunction are common among men with epilepsy. We investigated sexual hormone serum levels among men with newly diagnosed epilepsy, before starting any antiepileptic drug (AED), and then after starting carbamazepine (CBZ), to determine the role and effects of epilepsy versus CBZ in creating reproductive endocrine disorders. Methods : ...
متن کاملOn net reproductive rate and the timing of reproductive output.
Abstract: Understanding the relationship between life-history patterns and population growth is central to demographic studies. Here we derive a new method for calculating the timing of reproductive output, from which the generation time and its variance can also be calculated. The method is based on the explicit computation of the net reproductive rate (R0) using a new graphical approach. Usin...
متن کاملReproductive isolation grows on trees.
Despite rapid advances in the complementary fields of speciation genetics and molecular phylogenetics, little attention has been devoted to understanding how genetic changes associated with reproductive isolation accumulate across clades of species. We argue that comparative analyses of reproductive isolation QTL (quantitative trait loci) can generate unique insights into the underlying mechani...
