BACKGROUND Several studies on the association of tumor necrosis factor alpha (TNF-α) polymorphisms with recurrent pregnancy loss (RPL) risk have reported conflicting results. The present meta-analysis was conducted to provide a more precise estimation of these relationships and to investigate the real association between TNF-α polymorphisms and RPL. METHODS An extensive eligible literature se...

Some case-control studies have demonstrated that caffeine intake and high CYP1A2 activity increase risks of recurrent pregnancy loss (RPL) but the multifactorial effect is obscure. To investigate whether susceptible women who have more caffeine intake are at high risk of RPL, a case-control study of 58 cases with two or more RPL and fertile 147 controls was performed. The association between da...

Recurrent Pregnancy loss is defined as three or more consecutive pregnancy losses before 20 wks gestation. Usually causes are found in 70-80% of cases as chromosomal, anatomical defects, thrombophilias-both acquired and inherited, endocrine. But in 20-30% no definite cause is found. We searched electronic databases Pubmed from 1950-2016 using different keywords. As for the diagnosis, management...

OBJECTIVE To determine whether in vitro fertilization with preimplantation genetic screening (IVF/PGS) is cost effective compared with expectant management in achieving live birth for patients with unexplained recurrent pregnancy loss (RPL). DESIGN Decision analytic model comparing costs and clinical outcomes. SETTING Academic recurrent pregnancy loss programs. PATIENT(S) Women with unexp...

Recurrent pregnancy loss (RPL) defined as of two or more pregnancies is one the reasons why couples visit an ART clinic. 2-5% RPL cases show abnormal parental karyotype. Folic acid essential B vitamin involved in processes fundamental importance for cell division and embryo development. deficiency can have effect on many oocyte development, acquisition endometrial receptivity, implantation also...

Recurrent pregnancy loss (RPL) affects 2-3% of couples. Despite a detailed work-up, the etiology is frequently undefined, leading to non-targeted therapy. Viable embryos and placentae express PreImplantation Factor (PIF). Maternal circulating PIF regulates systemic immunity and reduces circulating natural killer cells cytotoxicity in RPL patients. PIF promotes singly cultured embryos' developme...

BACKGROUND Women with elevated natural killer (NK) cell frequency and function during pregnancy, suffer from recurrent pregnancy loss (RPL). In the present study, the possible effect of intravenous immunoglobulin (IVIG) administration on Th1 and Th2 cell frequency, cytokine secretion, and expression of transcription factors is compared between RPL patients and control group. MATERIALS AND MET...

BACKGROUND Recurrent pregnancy loss (RPL) which is generally known as >3 consecutive pregnancy losses before 20 weeks' gestation is seen in 0.5-2% of women. OBJECTIVE To evaluate the association of parental and fetal chromosomal abnormalities with recurrent pregnancy loss in our area and to analyze the frequency of three types of hereditary thrombophilia's; (MTHFR C677T polymorphisms, FV Leid...

BACKGROUND 15% of reproducing couples suffer from pregnancy loss(PL) and recurs in 2-3%. One of the most frequently hypothesized causes of unexplained PL refers to a defective maternal haemostatic response leading to uteroplacental thrombosis. Hereditary thrombophilia and antiphospholipid antibodies have been extensively described as risk factors for PL in women with unknown aetiology. Recently...
