Background: Recently, it has been found that exposure of sperm to PVP may cause submicroscopic changes in sperm structure and the sperm nucleus. The PVPinduced nuclear damage may have been due to breakdown of sperm membranes. Consequently, it is probable that exposure of sperm to PVP may impair embryo development. There are apparently no detailed reports regarding the specific effects of PVP on...

Background: Polycystic ovary syndrome (PCOS) is characterized by chronic anovulation and hyperandro genism and affects approximately 5-10% of women of reproductive age. In vitro maturation (IVM) of mammalian oocytes has become an efficient method to produce mature oocytes in order to use in assisted reproductive techniques such as in vitro fertilization (IVF), intra cytoplasmic sperm injection ...

background: mammalian oocytes are exposed to a mixture of many different growth factors and cytokines which provides an optimized microenvironment for oocyte maturation. in the lack of this natural microenvironment in vitro the quality of oocyte and embryos appears to be suboptimal. objective: this study was undertaken to investigate the effects of egf and lif on in vitro maturation fertilizati...

Medical treatments at the beginning and end of human life are highly contested in public discourse. Our study reveals factors shaping acceptance social egg freezing (or oocyte cryopreservation) as an assisted reproduction technology (ART) general public. Based on theory moral contextualism literature medical ethics, we deduce potential influencing attitudes toward cryopreservation (for example,...

Background With aging, the ovarian reserve is decreased and that is a major contributor to poor ovarian response to exogenous gonadotropins. The aim of the present study is to evaluate the role of Dexamethasone on ovarian response in infertile patients aged over 35 years undergoing IVF/ICSI cycles. MaterialsAndMethods In this triple blind placbo-control clinical trial study, a total of 72 infer...
