background: human fertility has been declined all over the world. advanced women’s age is one of the most important factors in determining the success of reproduction and ageing has negative impact on art outcome and advanced female age decreases the chance of live birth rates achieved using art, especially after 40 years of age. objective: to evaluate art outcomes regarding to pregnancy, abort...

background: implantation remains a limiting step in ivf/icsi. endometrial injury isa promising procedure aiming at improving the implantation and pregnancy rates after ivf/icsi. objective: the aim of this study was to evaluate the effect of endometrial injury induced in precedingcycle on ivf/icsi outcome. materials and methods: four hundred patients undergoing their first ivf/icsi cycle in two ...

Abstract Study question The purpose of this study is to compare cumulative live birth rate and perinatal outcomes embryos cultured in 20% oxygen 5% oxygen. Summary answer Atmospheric concentration not only affects the quality embryos, but also weight after embryo transfer. What known already Whether culture can effectively improve outcome embryonic pregnancy still controversial. There a lack sc...

BACKGROUND Outcomes of in vitro fertilization (IVF) treatment are traditionally reported as pregnancies per IVF cycle. However, a couple's primary concern is the chance of a live birth over an entire treatment course. METHODS We estimated cumulative live-birth rates among patients undergoing their first fresh-embryo, nondonor IVF cycle between 2000 and 2005 at one large center. Couples were f...

The aim of all assisted reproductive techniques (ART) is a live birth of a single healthy baby. Many clinical and laboratory strategies can influence the ART clinical outcomes. In this lecture we try to explore the clinical and laboratory strategies to maximize success in ART. Three are the main issues: 1. optimize the number of oocyte retrieved with an individualized controlled ovarian superov...

Research question How does the number of oocytes used affect cumulative live birth rate (CLBR) in endometriosis patients who had their vitrified for fertility preservation? Design Retrospective observational study including data from 485 women with underwent preservation January 2007 to July 2018. Survival curves and Kaplan–Meier plots were analyse CLBR according used. Endometriosis compared de...

BACKGROUND Minimal stimulation in vitro fertilization (mini-in vitro fertilization) is an alternative in vitro fertilization treatment protocol that may reduce ovarian hyperstimulation syndrome, multiple pregnancy rates, and cost while retaining high live birth rates. OBJECTIVE We performed a randomized noninferiority controlled trial with a prespecified border of 10% that compared 1 cycle of...

BACKGROUND Many studies on assisted reproductive technology examine live birth rate per cycle. However, after a cycle fails, couples often want to know what their chances are of having a live birth if they continue treatment. From a patients' perspective, the cumulative probability of live birth is more informative. MATERIALS AND METHODS This study includes patients who underwent fresh, froze...
