The most common definition of repeated implantation failure (RIF) is the failure to obtain a clinical pregnancy after three completed IVF cycles. This definition, however, may lead to misuse of the diagnosis. To disentangle this, we set up a mathematical model based on the following main assumptions: rate of success of IVF constant and set at 30%; and RIF postulated to be a dichotomous condition (yes or no) with a prevalence of 10%. On this basis, the expected cumulative chance of pregnancy after three and six cycles was 59% and 79%, respectively...

BACKGROUND: Vascular Endothelial Growth Factor and NK cells have an interrelated role in angiogenesis that is critical for placentation and success of in vitro fertilization. An attempt was made to assess a possible relationship between the two in this study. METHODS: A case control study was performed comparing the serum levels of VEGF-A and its receptor VEGF-R1 with levels of NK cells, activated NK cells and NK cytotoxicity in 62 women with Repeated Implantation Failure (RIF)...

OBJECTIVE: Although major advances have greatly improved the outcomes of assisted reproductive technology in the last two cascades, there remains significant difficulty in achieving pregnancy for many patients even after repeated attempts of IVF. Interestingly, recent studies have shown that transcutaneous electrical acupoint stimulation (TEAS) can improve the reproductive outcomes of select IVF patients. To determine the utility of TEAS in improving IVF outcomes in patients with a history of implantation failure, we conducted a retrospective study of clinical outcomes of women, who had a prior history of unsuccessful pregnancy outcome after IVF-embryo transfer (IVF-ET), following TEAS treatment...

Conflicting results exist for low molecular weight heparin (LMWH) and prednisolone when tested as separate adjuncts for the improvement of the clinical outcomes in patients with repeated implantation failures (RIF) undergoing IVF/ICSI treatment. Through a cohort study, we evaluated the combined effect of both drugs on pregnancy parameters in 115 women with RIF. Clinical pregnancy rate was the primary end point while the sample size was calculated through the results of a pilot study. Clinical and IVF cycle characteristics were also compared between the groups...

Turner's syndrome (TS) is depicted as a total or partial absence of X chromosome, and occurs in approximately 1/2200 of live born females. Generally, mosaic patients are diagnosed following karyotype analysis due to recurrent pregnancy loss, repeated in vitro fertilization (IVF) failure, and a history of malformed babies. The purpose of this case report is to show that even a selection of normal karyotype embryos can result in abnormalities for those with mosaic TS. A 32-year old patient who underwent IVF after ICSI-PGD, and was diagnosed with 45X/46XX karyotype...

The problem of infertility and reproductive losses maintains its urgency, as well as medical and social significance. Frequency of infertility in overall population, according to the data from different authors, varies from 9 to 18 per cent. Methods of aided reproductive technologies (ART) opened a new era in the field of correction of infertile marriage. As a result, more and more couples choose to solve this problem by means of aided reproductive technologies (ART): in-vitro fertilization (IVF) and embryo transfer (ET)...

BACKGROUND: Among subfertile couples undergoing assisted reproductive technology (ART), pregnancy rates following frozen-thawed embryo transfer (FET) treatment cycles have historically been found to be lower than following embryo transfer undertaken two to five days following oocyte retrieval. Nevertheless, FET increases the cumulative pregnancy rate, reduces cost, is relatively simple to undertake and can be accomplished in a shorter time period than repeated in vitro fertilisation (IVF) or intracytoplasmic sperm injection (ICSI) cycles with fresh embryo transfer...

Evidence for the effect of granulocyte colony stimulating factor (G-CSF) on infertile women undergoing in vitro fertilization (IVF) remains inconsistent. This study aimed to evaluate the effectiveness of G-CSF on infertile women undergoing IVF. PubMed and EMBASE databases were searched before August 2016. Comparing the transvaginal perfusion of G-CSF and placebo or no treatment, the available studies were considered. The pooled risk ratio (RR) with 95% confidence intervals (CIs) was used in the analysis and six studies were included...

BACKGROUND: Hysteroscopy, despite being the undisputed gold standard for the examination of the uterine cavity, is controversial as a routine procedure in infertile women. However, benign intrauterine conditions are common in women suffering repeated in vitro fertilization (IVF) failure, and growing evidence suggests a unique diagnostic and therapeutic role for hysteroscopy. Endometrial malignancy, on the contrary, is unreported by large published series of women with repeated IVF failures undergoing hysteroscopy, and its impact on fertility, for obvious reasons, has not been studied...

REVIEW
Margit Dueholm
This review includes an analysis of the clinical studies evaluating reproductive outcome and adenomyosis, and a review of studies on reproductive outcome and surgical treatment options for adenomyosis. Strict diagnostic criteria and classification of disease are needed for an image diagnosis of adenomyosis. Studies of in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) populations and women with surgically treated deep endometriosis have suggested that adenomyosis has a negative impact on reproductive outcome, although there are substantial variations between studies...

High endometrial receptivity in the window of implantation (WOI) is essential for successful implantation. However, a diagnostic tool with high specificity for impaired endometrial receptivity remains to be developed. We collected endometrium specimens during the WOI from patients with RIF and women who conceived after one IVF/ICSI attempt. We conducted mRNA microarray on the samples followed by relevant comparative and functional analysis. Microarray analysis revealed 357 dysregulated mRNAs between the two groups...

The benefit of endometrial scratch (ES) prior to embryo transfer is controversial. Systemic analysis has confirmed its potential benefit, especially in women with repeated IVF failures, yet most studies have focused on fresh embryo transfer, and its effect on vitrified-warmed embryo transfer (FET) cycles is yet to be explored. We hereby present our prospective, double-blind, randomized controlled study on the evaluation of the implantation and pregnancy rate after ES prior to natural-cycle FET. A total of 299 patients underwent natural-cycle FET and were randomized to receive ES (n = 115) or endocervical manipulation as control (n = 114) prior to FET cycle, and a total of 196 patients had embryo transfer (93 patients in each group)...

BACKGROUND: Atosiban is administered to women undergoing in vitro fertilization-embryo transfer (IVF-ET) to improve pregnancy outcomes. However, the results of this treatment were controversial. We conducted this meta-analysis to investigate whether atosiban improves pregnancy outcomes in the women undergoing in vitro fertilization (IVF). METHODS: Databases of PubMed, EMBASE, Web of Science, China BioMedicine, and Google Scholar were systematically searched. Meta-analyses were performed to investigate whether atosiban improves pregnancy outcomes in the women undergoing IVF...

IgA anti-β2glycoprotein I antibodies (IgA-anti-β2GPI) seems to be the most prevalent isotype in patients with Systemic Lupus Erythematosus (SLE) with a significant association to thrombotic events. Both SLE and antiphospholipid syndrome (APS) can be associated with implantation failure, fetal loss and obstetric complications. Recent reports highlight the clinical value of IgA-anti-β2GPI determination in supporting in vitro fertilization (IVF) treatment and IVF pregnancy outcomes. We report a 36-year-old female diagnosed with SLE, endometriosis and unexplained infertility...

The recent discovery of ovarian stem cells in postnatal mammalian ovaries, also referred to as putative stem cells (PSCs), and their roles in mammalian fertility has challenged the long-existing theory that women are endowed with a certain number of germ cells. The rare amount of PSCs is the major limitation for utilizing them through different applications. Therefore, this study was conducted in six phases to find a way to increase the number of Fragilis- and mouse vasa homolog (MVH)-positive sorted cells from 14-day-old NMRI strain mice...
