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...

European results of assisted reproductive techniques from treatments initiated during 1999, are presented in this third report. Data were collected mainly from pre-existing national registers. From 22 countries 538 clinics reported 258 460 cycles: IVF 125 370, ICSI 95 221, frozen embryo replacement (FER) 34 002 and oocyte donations (OD) 3867. In eight countries, where all clinics reported to th...

BACKGROUND As discontinuation in in vitro fertilization (IVF) programs has been associated with a poor prognosis, one hypothesis is that some couple-specific predictive factors in IVF may be shared with opposite effect by both success (i.e. live birth) and treatment discontinuation processes. Our objective was to perform a joint analysis of these two processes to examine the hypothesis of a lin...

BACKGROUND The success rate of IVF treatment is low. A recent systematic review and meta-analysis found that the outcome of IVF treatment could be improved in patients who have experienced recurrent implantation failure if an outpatient hysteroscopy (OH) is performed before starting the new treatment cycle. However, the trials were of variable quality, leading to a call for a large and high-qua...

BACKGROUND Failure of IVF treatment after a number of cycles can be devastating for couples. Although mild IVF strategies reduce the psychological burden of treatment, failure may cause feelings of regret that a more aggressive approach, including the transfer of two embryos, was not employed. In this study, the impact of treatment failure after two or more cycles on stress was studied, followi...

For the 10%-15% of American married couples who experience reproductive problems, in vitro fertilization (IVF) is the leading technologically advanced treatment procedure. Two important issues are at the center of policy debates regarding IVF markets: 1) expanding access to infertility treatment, and 2) how to encourage IVF clinics and patients to minimize the risk of multiple births, which can...

This article considers the early period of development of IVF in Ecuador, focusing on factors that shaped the decade after the nation's first successful IVF birth (1992–2002). It describes how a poorly resourced public healthcare sector compelled Ecuadorians towards private-sector medicine, which included assisted reproduction treatment, and how IVF clinics drew patients through the pervasive r...

The production of cloned animals is an inefficient process because of early or late embryonic losses. This study focused on the DNA fragmentation that occurs during embryonic development. The occurrence of DNA fragmentation was examined in bovine embryos produced by in vitro fertilization (IVF) and somatic cell nuclear transfer (NT) using the terminal deoxynucleotidyl transferase (TdT) nick-end...

OBJECTIVE The purpose of this study is to evaluate factors predictive of outcomes in women with highest follicle-stimulating hormone (FSH) levels ≥ 12 IU/L on basal testing, undergoing in vitro fertilization (IVF). METHODS A prospective cohort study was conducted at Stanford University Hospital in the Reproductive Endocrinology and Infertility Center for 12 months. Women age 21 to 43 undergoi...

BACKGROUND Elective single embryo transfer (eSET) enables the prevention of multiple pregnancies after in vitro fertilization (IVF). However, in Europe, the multiple pregnancy rate after IVF remains stable at approximately 23%, with SET occurring in 15% of all IVF cycles. In most European clinics, the decision for the number of embryos transferred is established through a form of shared decisio...
