Filter by:Salivary diagnostic testing is emerging as a less invasive, inexpensive alternative to serum analyte measurements with proven diagnostic accuracy in clinical settings. This study aims to continue analyzing aspects of the performance of salivary hormone competitive immunoassays for monitoring patient's reproductive hormone profiles in the reproductive cycle. Hormone levels will be monitored during treatment cycles for infertility.
The purpose of pilot study application is to build on the investigators' previous work that established the prospective association between stress and infertility. Specifically, the investigators hope to collect the preliminary data necessary to make them competitive to submit a R01 application to NIH for funding of a full-scale randomized controlled trial of an internet-based stress management program to examine its efficacy in decreasing stress and increasing pregnancy rates among women who have tried to get pregnant for 6-12 months without success. The program called Stress Free Now (SFN) was developed at the Cleveland Clinic and has been shown to be effective in lowering stress in a variety of populations. The program introduces concepts of mindfulness and cognitive-behavioral therapy to assist individuals in managing their stress levels. The intervention includes Internet-based interaction, daily emails and recommended relaxation practice of at least four days per week. Using targeted Facebook Ads and other recruitment modalities, the investigators will randomize 40 women ages 18-34 who have been trying to conceive for 6-12 months without success. The PI has been enrolling women in a similar study using this mechanism and has found it to be an efficient and cost-effective method of identifying potentially eligible individuals. Women will be randomized to SFN or a wait list control condition and will be followed for up to three months post-randomization with weekly journals as they try to conceive. The primary outcome of this randomized controlled trial is stress level, as measured by salivary alpha-amylase, while the secondary outcome will be pregnancy rate at the end of the three-month follow-up period.
The aim of the study is to perform a French multicenter prospective interventional study in order to assess the feasibility and safety of ovarian hyperstimulation for oocyte / embryo cryopreservation in young women with breast cancer. The oncologic and reproductive benefit / risk ratio will be investigated in the oncology and reproductive area.
About 15% of couples consult for difficulties achieving pregnancy. In about two-thirds of cases, a male component is identified, but is not always sufficient to explain infertility. In the majority of cases, the cause cannot be clearly identified and multiple abnormalities may be detected in both partners. Many factors concerning lifestyle and environment (medications, alcohol, smoking, pollution, exposure to heat, toxins, xenobiotic oestrogens, etc.) may impact on fertility. These factors may also impact on the fertility of the children conceived, which is described as an intergenerational effect (alteration of the fertility of boys exposed to smoking in utero). Few scientific studies with a high level of proof have been published on the impact of smoking on the couple's fertility. Gonadal functioning and the quality of gametes can be altered by these environmental factors, which may trigger a process of apoptosis or alteration of the DNA of gametes (sperm DNA fragmentation). Other modifications include DNA methylation and histone acetylation, which control gene expression and are grouped under the term epigenetic modifications. More recently, oestrogens has been shown to be involved in male reproductive function by acting on spermatogenesis, spermiogenesis and epididymal maturation. Demonstration of an active aromatase (Arom) (mRNA, protein and activity) in ejaculated human spermatozoa suggests the synthesis of small quantities of oestrogens in spermatozoa. The study of transcript profiles could provide information about the quality of spermatogenesis and/or spermiogenesis and during the first steps of embryonic development. Confocal microscopy has colocalized the aromatase on the head, midpiece and tail and can be used to assess the quality of the acrosome with anti-CD-46 monoclonal antibody. Even low concentrations of xenobiotic oestrogens can exert biological effects on certain functions of murine or human spermatozoa, accelerating capacitation and the acrosome reaction. These factors are all the more effective when they act in combination, as human gametes appear to be more sensitive to their action than murine gametes All studies conducted to date have investigated the impact of toxins either on one of the partners or in the children born to the couple. No detailed and high-level scientific study has studied both partners and the quality of their embryos.
The number of copies of mitochondrial genes (mtDNA or "MitoScore") is related to the energy supply of the embryo, which can affect its ability to implant in the maternal uterus. The objective of this study is to analyse the potential of MitoScore before embryo transfer as a marker to identify and select the embryo with greater capacity of implantation. First of all, chromosomally normal embryos will be selected and mtDNA copies will be quantified. Finally, embryos with less copies of mtDNA will be considered for embryo transfer.
This study aims to investigate the treatment of absolute uterine infertility (AUI) due to congenital or surgical absence of a uterus or presence of a nonfunctioning uterus. The investigators will follow a model based on a Swedish study to enroll 20 women with functioning ovaries and successfully transplant the uterus from either a living or cadaveric donor, with the goal of live birth after transplantation.
Is postoperative IUI better than expectant management in infertile endometriosis patients with good prognosis based on their EFI score? (A single centre randomised controlled trial).
Does prolonged GnRH downregulation prior to ART improve the clinical pregnancy rate in postoperative endometriosis patients? (A single centre randomised controlled trial)
The supplementation of Dehydroepiandrosterone (DHEA) has been used in some centers for patients with previous poor ovarian reserve and response in an attempt to improve pregnancy outcomes. However, there still has controversy on the clinical effect on the 75mg/d for the use,especially in Asian people. Whether the double dosage of DHEA in patients with poor ovarian reserve and response in China can improve the IVF outcome with little side effect is unknown. The aim of this randomized controlled study is to compare the effect of a higher dose (150mg daily) and a standard dose (75mg daily) of DHEA on the number of oocytes obtained in poor ovarian responders. The effect of DHEA action on the cumulus cells will be examined.
The purpose of this clinical trial is to collect imaging data on embryos followed to blastocyst stage (Day 5-6) for ongoing development and validation of the Eeva System.
