BACKGROUND Hyperhomocysteinemia has been described as a risk factor for unexplained recurrent pregnancy loss. Increased levels of homocysteine may be due to inadequate dietary intake of folate and vitamin B12 and inherited defects within the methionine-homocysteine pathway such as MTHFR C677T gene polymorphism. However, the association between hyperhomocysteinemia and sterility problems have be...

OBJECTIVE MicroRNAs (miRNAs) regulate gene expression during the peri-implantation period. The purpose of this study was to investigate whether genetic polymorphisms in the four miRNAs associated with fetal or placental development play roles in the development of idiopathic recurrent pregnancy loss (RPL) in Korean females. STUDY DESIGN A case-control study involving 225 controls and 387 wome...

This document contains the definitions of infertility and recurrent pregnancy loss as defined by the Practice Committee of the American Society for Reproductive Medicine. It replaces the document titled, "Definitions of Infertility and Recurrent Pregnancy Loss," last published in 2008, Fertil Steril 2008;90(Suppl 3):S60.

BACKGROUND This case-control study was designed with the aim of evaluating the role of sperm, oxidative stress and DNA damage in idiopathic recurrent pregnancy loss (iRPL). This pilot study is the first study done on the Indian population which reports the association between DFI, TAC and ROS in couples experiencing iRSA. METHODS Twenty infertile men with a history of iRPL and 20 fertile cont...

OBJECTIVE To measure serum leptin and insulin levels in women with recurrent pregnancy loss using modified methods of High Performance Liquid Chromatography (HPLC), and to examine their influence on recurrent loss at different pregnancy trimesters. METHODS A case control study was conducted from, 1 September 2008 to 30 December 2009 in the Obstetric and Gynecological Department-Al-Khadimiya T...

OBJECTIVE Key molecules involved in microRNA (miRNA) biogenesis, such as DROSHA, XPO5, and DICER, have been identified in trophoblast cells, confirming that the miRNA biogenesis pathway is active in human placenta. In addition, miRNAs regulate uterine gene expression associated with inflammatory responses during the peri-implantation period and participate in maternal-fetal immune tolerance. Th...

AIM The aim of this study was to determine plasma Growth Arrest Specific Protein 6 (GAS6) protein levels in patients with unexplained recurrent pregnancy loss (RPL) and compare them to those of pregnant and to healthy non-pregnant women with a history of at least one live delivery. PATIENTS AND METHODS A total of 205 women were included in the study. Of these, 68 were diagnosed with unexplain...

Transforming growth factor β1 plays a significant role in pregnancy outcome. We investigated the association of TGFB1 exon 1 (rs1800471, rs1800470) and promoter region (rs1800469, rs1800468) polymorphisms with recurrent pregnancy loss (RPL) in 675 Tunisian women: 304 women with a history of three consecutive pregnancy losses of unknown etiology with the same partner and 371 age-matched multipar...

Idiopathic recurrent pregnancy loss (IRPL) is defined by three or more consecutive miscarriages occurring before the twentieth week of gestation as a result of unidentified etiological factors. The results of previous studies have indicated that prothrombotic factors play a pathogenic role in early and late pregnancy. This study aimed to identify inherited prothrombotic and hypofibrinolytic ris...
