Background: Polycystic ovary syndrome (PCOS) is one of the most common endocrine metabolic disorders of reproductive age women. The main signs of PCOS are as follows: androgen excess, menstrual dysfunction, infertility, obesity, and other numerous health problems. By different authors, the disorder affects 2-28% of reproductive age women. Materials and Methods: Polycystic ovary syndrome is char...

Despite numerous indices proposed to predict the evolution of mating systems, a unified measure of sexual selection has remained elusive. Three previous studies have compared indices of sexual selection under laboratory conditions. Here, we use a genetic study to compare the most widely used measures of sexual selection in natural populations. We explored the mating and reproductive successes o...

background: nano-particles are extensively employed in most industries. several studies have been started to explore the probable detrimental effects of nano-particles on human reproduction. however, there is insufficient and controversially evident of effects of silver nano-particles on sperm parameters and other reproductive indices. objective: investigation of the effects of silver nano-part...
