View clinical trials related to Repeated Implantation Failure.
Filter by:This is a prospective, clinical, monocentric study aimed to collect biological samples and study microbiota from subjects suffering from subjects with recurrent cervicovaginitis, subjects with endometriosis, subjects with repeated implantation failures and from healthy volunteers. Microbiota is a complex consortium of microorganisms, located at the mucosal level (in particular intestinal, oral and vaginal) having a key role in human health and in the onset of several diseases. Microbiota alterations have been found in several diseases (gastrointestinal, metabolic, renal, oncological, gynaecological). The study will allow to: - Provide biological samples (faeces, saliva, vaginal, urine) from healthy volunteers and patients suffering from selected disease to the first Italian microbiota biobank; - Study microorganisms using different in vitro and in vivo techniques; - Study the link between the microbiota and the disease. This study is part of the BIOMIS project (Project Code: ARS01_01220), presented as part of the "Avviso per la presentazione di progetti di ricerca industriale e sviluppo sperimentale nelle 12 aree di specializzazione individuate dal PNR 2015-2020" and admitted to funding under the National Operational Program "Ricerca e Innovazione" 2014-2020 by directorial decree of MIUR - Department for Higher Education and Research - n. 2298 of 12 September 2018. BIOMIS includes several clinical studies that enrol patients with different pathologies to collect and store biological samples and study microbiota.
Despite recent advances in clinical and laboratory techniques of Assisted Reproductive Technology (ART), the pregnancy rate remains around 30% per cycle. It has been estimated that 50% to 75% of lost pregnancies are due to failure of implantation. The process of implantation is a locally controlled paracrine/juxtacrine-mediated phenomenon. Successful implantation depends on the synchronized "cross-talk" between a functional blastocyst and a "receptive" endometrium. This process leads to apposition, attachment and invasion of embryos and subsequent normal placentation. So the objective of this study is investigate the impact of intrauterine injection of human chorionic gonadotropin (hCG) at the day of ovum pick-up on implantation and pregnancy rates in patients with recurrent implantation failure.
Characterization of the uterine microbiome in women with repeated implantation failure as well as in normal fertile women.
Atosiban, administered at embryo transfer, can improve the implantation rate and the clinical pregnancy rate in patients with repeated implantation failure undergoing IVF-ET (in-vitro fertilization and embryo transfer).
