background: implantation failure is one of the most important factors limiting success in ivf treatment. the majority of trials have demonstrated favorable effect of endometrial injury on implantation success rate especially in women with recurrent implantation failure, while some studies failed to detect any benefit. objective: the purpose of our trial was to explore whether endometrial injury...

objective:  to investigate the reproductive outcome of artificial endometrial preparation with exogenous steroids for frozen-thawed embryo transfer with and without pre-treatment with depot gonadotropin releasing hormone agonist (gnrh-a) in women with regular menses. amaterials and methods: this is a prospective randomized clinical trial conducted in two rt centers on 176 women undergoing froze...

OBJECTIVE To describe a case of monozygotic triplet pregnancy following egg donation and the transfer of a single frozen-thawed embryo. DESIGN Case report. SETTING District general hospital and regional department of fetal medicine in northeast England. PATIENT(S) A 38-year-old woman with a 2-year history of primary infertility due to severe endometriosis and poor ovarian reserve who conc...

This paper provides a concise review of single embryo transfer (SET) in cycles using fresh embryos as well as in cycles using frozen-thawed embryos. Relevant studies were identified by a computerized search in PubMed for the period 1995-2004. The pregnancy rates, delivery rates and multiple pregnancy/birth rates were evaluated after fresh or frozen embryo transfer as well as cumulative delivery...

Background Women undergoing in vitro fertilization (IVF) cycles should successfully go through multiple points during the procedure (i.e., implantation, clinical pregnancy, no spontaneous abortion and delivery) to achieve live births. In this study, data from multiple cycles and multiple points during the IVF cycle are collected for each individual to model the effects of factors associated wit...

BACKGROUND GnRH agonist and antagonist were developed to control the premature release of LH surge. There is some difference between two protocols. OBJECTIVE We compared the outcome of frozen-thawed embryo transfer in infertile women who used GnRH agonist or antagonist protocol for previous COH cycle and evaluation of any adverse effect of GnRH antagonist on oocyte and embryo. MATERIALS AND...

This investigation describes features of in vitro fertilisation (IVF) patients who never returned to claim their embryos following cryopreservation. Frozen embryo data were reviewed to establish communication patterns between patient and clinic; embryos were considered abandoned when 1) an IVF patient with frozen embryo/s stored at our facility failed to make contact with our clinic for > 2 yrs...

BACKGROUND Frozen- thawed embryo transfer is an essential part of ART treatment and outcomes of this procedure are associated with several clinical factors. Several studies have showed an increase level of IVF outcomes in women with sufficient vitamin D. OBJECTIVE whether treatment of vitamin D insufficiency can improve pregnancy rates in frozen-thawed embryo transfer cycles. MATERIALS AND ...
