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...

Background: Chemical activation is the most frequently method for artificial oocyte activation, resultant in high fertilization rates. The aim of this prospective randomized controlled study is evaluating the effect of calcium ionophore on fertilization and pregnancy rate in infertile men suffering from teratoospermia. Materials and Methods: 38 women with teratoospermic partner were divided int...

BACKGROUND To create a more effective selection standard for early embryos, we developed a new grading system consisting of conventional morphological evaluation in combination with analysis of blastomere nuclei. METHODS A total of 744 embryos used during 459 cycles of embryo transfer on day 2 and blastocyst transfer were subjected to retrospective analysis. The overall implantation rate was ...

background: premature luteinization during in vitro fertilization was commonly happened before the introduction of gnrh analogues. high level of unwanted progesterone is associated with adverse pregnancy outcome and is thought to be induced by inappropriate lh elevation.objective: to evaluate the progesterone level on the day of human chorionic gonadotropin (hcg) triggering in gnrh agonist and ...

OBJECTIVE To determine the relative efficacy of ultrasound-guided embryo transfer and embryo transfer by clinical touch alone. DESIGN Systematic review and meta-analysis of randomized, controlled trials comparing ultrasound-guided embryo transfer with embryo transfer by clinical touch alone. SETTING Infertility centers providing treatment with in vitro fertilization/embryo transfer. PATIE...

BACKGROUND We conducted a survey of the infection burden associated with the implantation of cardiac implantable electronic devices (CIEDs) in Japan. METHODS The institutes were selected using annual device implantation data provided by Medtronic Japan Co., Ltd. The data sampling period was from January 1 to December 31, 2013. Institutes were classified into Group P, at which only pacemakers ...

This study was designed to compare the efficiency of the Cryotop and Calibrated plastic inoculation loop (CPIL) devices for vitrification of rabbit embryos on in vitro development and implantation rate, offspring rate at birth and embryonic and fetal losses. CPIL is a simple tool used mainly by microbiologists to retrieve an inoculum from a culture of microorganisms. In experiment 1, embryos we...
