in this research we have studied the effect of some transition-metals (cu, ag and au) substitutions on two-electron reduction potential of flavins by application of dft method. all geometries have been optimized at blyp level of theory and “6-31+g** + lanl2dz” mixed basis set. the frequency job at the same method and basis sets has been performed to obtain gibbs free energy of compounds. it h...
Although abnormal semen parameters are generally considered to be poor predictors of fertility, Semen Analysis (SA) parameters are often used as a screening test to detect male factor infertility. Certainly, men with azoospermia or severe oligozoospermia have markedly impaired fertility potential [1-3].
