Recurrent implantation failure is today the major reason for women completing several IVF/intracytoplasmic sperm injection attempts without having achieved a child, and is probably also the explanation for many cases of unexplained infertility. Most causes of recurrent miscarriage are still poorly elucidated, but from a theoretical point of view recurrent(More)
Sporadic miscarriage is the most common complication of early pregnancy. Two or three consecutive pregnancy losses is a less common phenomenon, and this is considered a distinct disease entity. Sporadic miscarriages are considered to primarily represent failure of abnormal embryos to progress to viability. Recurrent miscarriage is thought to have multiple(More)
Homozygous carriage of a 14 base pair (bp) insertion in exon 8 of the HLA-G gene may be associated with low levels of soluble HLA-G and recurrent miscarriage (RM). We investigated the G14bp insertion(ins)/deletion(del) polymorphism in 339 women with unexplained RM and 125 control women. In all patients and patients with secondary RM after a firstborn boy,(More)
Previously, siblings of patients with idiopathic recurrent miscarriage (IRM) have been shown to have a higher risk of miscarriage. This study comprises two parts: (i) an epidemiological part, in which we introduce data on the frequency of miscarriage among 268 siblings of 244 patients with IRM and (ii) a genetic part presenting data from a genome-wide(More)
Pregnancy loss prior to viability is common and research in the field is extensive. Unfortunately, terminology in the literature is inconsistent. The lack of consensus regarding nomenclature and classification of pregnancy loss prior to viability makes it difficult to compare study results from different centres. In our opinion, terminology and definitions(More)
With respect to recurrent pregnancy loss (RPL), unfortunately there is very little consensus about which investigations are useful for identifying causes and evaluating the prognosis, and also about which treatments are effective. In this review, arguments are given for the claim that this lack of consensus may mainly be because studies in the field of RPL(More)
STUDY QUESTION Are non-visualized pregnancy losses (biochemical pregnancy loss and failed pregnancy of unknown location combined) in the reproductive history of women with unexplained recurrent miscarriage (RM) negatively associated with the chance of live birth in a subsequent pregnancy? SUMMARY ANSWER Non-visualized pregnancy losses contribute(More)
Recent genome-wide association (GWA) studies of type 2 diabetes (T2D) have implicated IGF2 mRNA-binding protein 2 (IMP2/IGF2BP2) as one of the several factors in the etiology of late onset diabetes. IMP2 belongs to a family of oncofetal mRNA-binding proteins implicated in RNA localization, stability, and translation that are essential for normal embryonic(More)
Most relevant studies in animals and humans indicate that some degree of systemic or uterine inflammation is necessary both for normal implantation and pregnancy. However, if inflammation becomes too excessive it might cause pregnancy complications such as fetal resorption/miscarriage. The main regulator of the correct level of inflammation at the(More)
A 14-base pair (bp) long insertion (ins)/deletion (del) polymorphism in exon 8 in the 3'-untranslated region of the human leukocyte antigen (HLA)-G gene is suggested to affect transcription of the gene. Carriage of the G14bp ins is associated with low levels of soluble HLA-G and increases the risk of recurrent miscarriage (RM). Due to existence of strong(More)
