Filter by:This study aims to explore the potential correlation between decreased ovarian reserve and previous history of early miscarriage.
To compare the abv3-integrin expression in endometrium tissue among RIF women between the GnRH analogue with Aromatase Inhibitor (Group A) , GnRH analogue with progesterone (Group B) and GnRH analogue alone as control group (Group C)
This is a pilot study with the aim to investigate the beneficial effect of bicarbonate buffered medium containing hyaluronan and recombinant human albumin (EmbryoGlue®, Vitrolife) in patients with documented repeated implantation failure on live birth per randomized subject as primary endpoint.
This study aims to characterize the association between history of pregnancy complications and M2 carrier status in IVF patients and the utility of M2 haplotype preimplantation genetic testing (PGT) in embryos produced by carrier couples. Participants in this study will be screened for the M2 variant. History of pregnancy complications and miscarriages will be studied in order to determine potential associations with M2 carrier-ship.
Development of mole was not associated with segregation of mutated NLRP7 allele in the haploid oocyte. We hypothesize NLRP7 is a maternal factor involved in regulating early embryo development or embryo-uterine interaction. In the proposed study, we seek to identify novel genetic variants and mutations of NLRP7 in women who experienced RM/HM. Genetic association study and haplotype analysis are performed to test assocation between NLRP7 gene and female reproductive performance. Immunohistochemical staining, RT-PCR, and Western blot analysis are used to investigate expression pattern of NLRP7 in endometrium and placenta. Two approaches are used to characterize functional significance of genetic variants/mutations. The first approach will be based on mutagenesis and the second approach will be based on induced pluripotent stem cells (iPSCs). Results obtained from the proposed study will provide novel insight into mechanism of embryo development and implantation.
Recurrent unexplained spontaneous miscarriage (RSM) is defined as three consecutive pregnancy loss prior to 20 weeks from the last menstrual period. 1% to 2% of women experience RSM. Treatment of URSM is a challenging issue. The currently available lines of treatment according to simplicity of use, reliability and degree of invasiveness include corticosteroids, sildenafil citrate, aspirin, heparin and immunoglobulins (besides good antenatal care), but up to now there are no prospective randomized studies, powerful enough, to determine a significant difference between these therapeutic protocols, with any of the above mentioned pharmacological agents. Sildenafil Citrate (Viagra®), a vasodilator, is also described as an anti-inflammatory agent. While improving uterine blood flow in the proliferative phase, NO may have detrimental effects at the level of the endometrium during the implantation window. The NO- mediated release of cytokines such as tumour necrosis factor- from activated natural killer cells has been implicated as a cause of implantation failure. Based on these observations, this study attempts was made to study uterine arteries and sub-endometrial blood flow during the luteal phase in normal fertile women and in patients with Unexplained recurrent miscarriage
Miscarriage affects one in five pregnancies and little progress has been made in understanding and treating this distressing condition. C. trachomatis is the most common sexually transmitted infection in the UK. C. trachomatis infection can have serious health consequences, including fallopian tube damage. Untreated C. trachomatis infection and tubal damage have been associated with miscarriage and adverse pregnancy outcomes such as preterm birth, low birth weight and stillbirth. A cohort study is needed to establish the prevalence of tubal disease in women with recurrent miscarriages. HyCoSy will be performed to identify tubal disease and establish the magnitude of the problem in the recurrent miscarriage population. The prognosis of tubal disease on miscarriage and other obstetric outcomes, and the role of medical interventions such as tubal surgery (to treat hydrosalpinx) on reducing miscarriage and adverse obstetric outcomes will also be studied. Objectives 1. Establish the prevalence of hydrosalpinx in the recurrent miscarriage population. 2. Establish the prognosis of women diagnosed with recurrent miscarriage with concurrent hydrosalpinx. 3. Explore the role of tubal surgery for improving reproductive outcomes in women with recurrent miscarriage population and hydrosalpinx.
Recurrent pregnancy loss (RPL) is a clinical problem affecting 1-5% of couples of reproductive age. The contribution of thrombophilia to RPL is disputed. This controversy is partly due to low sensitivity of the genetic variants currently used to evaluate hereditary thrombophilia: the Leiden mutation (identified as rs6025) in the coagulation factor 5 (F5L) gene and mutation G20210A (identified as rs1799963) in the prothrombin (PT) gene. Our objective was to determine whether a wider algorithm that includes clinic and genetic variants associated with thrombophilia could be more useful in the prediction for RPL than FVL and PT alone.
The purpose of this study is to determine whether ovarian reserve is related to recurrent pregnancy loss
The purpose of this study is to determine whether Cyclosporin A (CsA) - an immunosuppressant drug - in early pregnancy will reduce the risk of miscarriage in women who had a history of unexplained recurrent miscarriages, as compared with that treated with Dydrogesterone-an active comparator. The hypothesis is based on the evidence found in vitro and in vivo experiments that CsA can induce maternal-fetal tolerance so that it may reduce the risk of miscarriage.
