Background To compare the pregnancy outcomes after two embryos versus three embryos transfers (ETs) in women undergoing in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) cycles. MaterialsAndMethods This retrospective study was performed on three hundred eighty seven women with primary infertility and with at least one fresh embryo in good quality in order to transfer at each ...

OBJECTIVE We compared 12-month pregnancy and live birth rates in patients with polycystic ovarian disease undergoing 5-, 10-, and 15-point laparoscopic ovarian electrocauterization. METHODS This was a prospective, randomized study performed at the Dabirashrafi Fertility and Endoscopy Research Center, Tehran, Iran. The study included 187 patients with polycystic ovarian disease who were random...

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 ...

OBJECTIVE To present a report on assisted reproductive technologies (ART) cycles performed in 2006 in Canada and show trends in outcomes over time. This is the sixth annual report from the Canadian ART Register (CARTR). DESIGN Prospective cohort study. SETTING Twenty-five of 25 ART centers in Canada. PATIENT(S) Couples undergoing ART treatment in Canada during 2006. INTERVENTION(S) ART ...

BACKGROUND Preimplantation genetic screening (PGS) has increasingly been used in the past decade. Here we present a systematic review and meta-analysis of RCTs on the effect of PGS on the probability of live birth after IVF. METHODS PubMed and trial registers were searched for RCTs on PGS. Trials were assessed following predetermined quality criteria. The primary outcome was live birth rate p...

PROBLEM In Japan, marital age and women's age at the first pregnancy are continuing to increase year by year. However, information concerning subsequent live birth rate according to maternal age and number of previous recurrent miscarriages is limited. METHOD OF STUDY We studied a total of 1250 unexplained patients suffering two or more consecutive miscarriages. We examined the live birth rat...

Background and Objective: In- vitro fertilization (IVF) is one of the approved treatment options for infertility. Despite many progresses in this field, its success rate is about 20 -25%. Utilization of drugs which suppress or decrease uterine smooth muscle contraction before embryo transfer, theoretically can improve fertility by increasing implantation rate. This study was designed to evaluat...

PURPOSE Blastocyst transfer has been recommended to raise the implantation rate without affecting the pregnancy rate. The objective of this meta-analysis is to systematically evaluate whether the live birth rate and other pregnancy outcomes can be improved by blastocyst transfer compared with cleavage-stage embryos transfer. MATERIALS AND METHODS EMBASE and MEDLINE databases were searched for...

BACKGROUND Growth hormone (GH) is used as an adjuvant therapy in in vitro fertilization and embryo transfer (IVF-ET) for poor ovarian responders, but findings for its effects on outcomes of IVF have been conflicting. The aim of the study was to compare IVF-ET outcomes among women with poor ovarian responders, and find which subgroup can benefit from the GH addition. METHODS We searched the da...

BACKGROUND This study was done to test the hypothesis that intrauterine insemination (IUI) using a soft-tip catheter results in a higher live birth rate than IUI using a hard-tip catheter. METHODS Five hundred and forty patients were randomized into those inseminated with a soft-tip catheter (group 1, n = 267) and those inseminated with a hard-tip catheter (group 2, n = 269). Four patients we...
