Active clinical trials for "Infertility"

This study investigates the presence of a possible link between treatment with danazol and expression of endometrial αvβ3 integrin which might allow tailoring of danazol treatment to the subset of repeated IVF/ET failure that might benefit most from it. 38 eligible ovulatory women were recruited aged 20 - 38 years with unexplained recurrent implantation failure (RIF). Timed suction endometrial biopsy was obtained from participants during the implantation window of the pretreatment cycle, followed by immunohistochemical staining for endometrial αvβ3 integrin expression, scored using H-score. Participants were treated with danazol (Danol® 200mg capsules, Sanofi, Guildford, UK) in daily dosage of 400 mg for 12 weeks. Post-treatment suction endometrial biopsy was obtained during the implantation window following the first ovulation after danazol treatment and endometrial αvβ3 integrin expression was compared to the pretreatment cycle.

There are different controlled ovarian hyperstimulation protocols utilized in infertility patients. In this study, our aim is to specifically compare three protocols in poor responding infertility patients.

The purpose of the study is to determine whether administration of dietary supplement of astaxanthin with vitamin E improves the quality of sperm, fertilization and embryo development in Assisted Reproduction Techniques (ART) procedures.

The addition of heparin increases pregnancy outcome parameters in poor responders undergoing In Vitro Fertilisation (IVF)

In order to learn more about women's health issues that occur over the lifespan, the Women's Health Study: from Adolescence to Adulthood is building a biorepository and database. The biorepository collects, processes and stores samples (such as urine, saliva, blood, cells, tissue and peritoneal fluid) until they are needed for research. The database contains de-identified information about our study participants. The biorepository and database are being created to serve as a resource for researchers from Boston Children's Hospital, Brigham and Women's Hospital and outside institutions.

Endometrial injury increases clinical pregnancy rate in normoresponder patients undergoing long agonist protocol intracytoplasmic sperm injection cycles with single embryo transfer.

In combination with the existing literature, previous work indicates that 1) women with poor ovarian response fulfilling the "Bologna criteria" have very low pregnancy rates, irrespective of age 2) current treatment protocols demonstrate ongoing pregnancy rates that do not exceed 8.5% and 3) corifollitropin alfa followed by hpHMG might increase ongoing pregnancy rates in young patients (<40years old) fulfilling the criteria. These findings provide a strong rationale for a definitive large RCT. The COMPORT study will provide conclusive evidence regarding the superiority or not of this novel protocol with corifollitropin alfa followed by hpHMG for the treatment of young poor ovarian responders fulfilling the Bologna criteria.

One of the main factors in the success of in-vitro fertilization is the quality of the environment of the embryo. In contrast to maternal age, the environment in which the embryo develops is a modifiable factor. Many techniques, such as assisted hatching and perfecting culture media have been attempted in order to reproduce as much as possible the natural, physiological environment of the mother for the embryo in in-vitro fertilization. However, the different new culture media used are devoid of growth factors normally secreted by uterine cells that enhance the interaction between the embryo and its environment. Because the endometrial lining of the uterus secretes many different cytokines necessary for growth of the embryo, a new procedure has been developed to mimic the natural environment of the growing embryo using autologous (patient's own) endometrial cells in co-culture with the embryo. Endocell, a product developed by Genévrier Laboratories, received commercial authorization in France in 2011. It is the only system of autologous embryo-endometrium co-culture available on the actual market. The process consists of developing the embryo on a monolayer of the patient's own endometrial cells in order to favor its growth until the blastocyst stage (day 5) and to improve its implantation.

The rational of the study is to assess the pregnancy rate after the transfer of frozen blastocyst in natural cycle controlled by external administration of hCG.

This trial investigates the immunogenicity of FE 999049 in repeated cycles.
