Background: Most studies show that 9 to 24% of people who are in in vitro fertilization (IVF) cycles are women who respond poorly to ovarian stimulation. Women with poor ovarian response (POR) are a group of infertile patients whose ovarian reserve, ovarian response to medication, and the quality of ovum are declining. Therefore, the number of female cycles, the number of fetuses from the oocyt...

Background: Ovarian reserve and ovarian response both are of the most important key factors in infertility treatment. Anti mullerian hormone (AMH) is one of lab tests that can predict ovarian reserve. relation between this assay and ovarian response can guide physition to choose the best protocol for the worst reserve. Materials and Methods: In a prospective cohort study, 110 infertile women (2...

introduction: the incidence of sperm and oocyte premature chromosome condensation (pcc) in the failed fertilized oocytes that were taken after routine in viro fertilization (ivf) and intracytoplasmic sperm injection (icsi) programs were investigated. materials and methods: in this study, 364 air-dried preparations of failed fertilized oocytes after either ivf or ocsi procedures were analyzed. t...

background: there has been an increase in number of obese infertile females booked for advanced infertility treatment procedures like in vitro fertilization (ivf) and intra cytoplasmic sperm injection (icsi). the knowledge of impact of body mass index (bmi) on reproductive outcome can help to counsel these patients. objective: to compare reproductive outcome in females of different bmi after ic...

We investigated the ability of reactive oxygen species (ROS), such as hydrogen peroxide (H2O2), hydroxyl radical (OH), and hypochlorous acid (HOCl) to overcome the defensive capacity of cumulus cells, and elucidate the mechanism through which ROS differentially deteriorate oocyte quality. Metaphase II mouse oocytes with (n=1634) and without cumulus cells (n=1633) were treated with increasing co...

objective: currently, there is no agreement on the optimal urinary derived human chorionic gonadotropin (u-hcg) dose requirement for initiating final oocyte maturation prior to oocyte collection in in vitro fertilization (ivf), but doses that range from 2500- 15000 iu have been used. we intended to determine whether low dose u-hcg was effective for oocyte maturation in ivf/intracytoplasmic sper...

The aim of this study was to investigate 2 quantification criteria to evaluate the developmental condition of follicles cohort and clarify their impacts upon the determining of human chorionic gonadotropin trigger timing and the reproductive outcome: the proportion of mature follicles in growing follicles cohort on the day of human chorionic gonadotropin trigger and the peak estradiol level per...
