Active clinical trials for "Infertility"

Many infertile patients have a decreased chance of becoming pregnant when using in vitro fertilization (IVF). For these patients, many different treatments are available, but none of them have been shown to be better than the others. We are testing which of three different treatments are better than the others. Patients who are expected to have a decreased response to ovarian stimulation will be randomized to either a microflare protocol, an antagonist protocol, or a demi-halt protocol.

Testicular dysgenesis syndrome (TDS) is known to cause epigenetic abnormalities in spermatozoa. Anogenital distance (AGD) is considered to be a suitable clinical marker of TDS, but the direct link between AGD and epigenetic abnormalities is still missing. Infertile men (n=10) presenting with shortened AGD and a control group of normal semen donors (n=10) with normal AGD will then be asked to provide one semen sample each. Using a flow cytometer and sorter (FACS) their spermatozoa will be sorted into populations of spermatozoa with/without DNA fragmentation or with/without chromatin decondensation. These sorted populations of spermatozoa will then be examined for differences in epigenetic imprinting differences using whole genome expression analysis. Whereas the sorting of spermatozoa will be carried out in Basel, the epigenetic analysis will be carried at the University of Geneva.

The main purpose of the study was to evaluate the overall clinical value of GERI+ as an integrated embryo culture and assessment system, providing an undisturbed culture environment, continuous monitoring of embryo development and automated scoring using a predictive algorithm.

The purpose of this study is to determine if the use of Autologous Endometrial Coculture (AECC) in young in vitro fertilization (IVF) patients with poor ovarian reserve improves pregnancy outcome.

Hypothesis: a special solution for improving human embryo implantation, when added to the solution during embryo transfer, will improve implantation rates in embryo transfers using previously frozen embryos.

Women undergoing in vitro fertilization (IVF) therapy, who are low responder and agree to enter the trial will be randomized to a study group, for whom embryo transfer will be done on the same day as oocyte aspiration and fertilization; and a control group for whom embryo transfer will be performed 48 to 72 hours later, as is the current accepted practice.

This is a pilot study which aims to determine the role of IMSI in poor responders.

The purpose of this study is to prove that a higher clinical pregnancy rate can be achieved with a 42 to 44 hour time interval between ovulation trigger and intrauterine insemination than a 36 to 38 hour time interval in stimulated cycles utilizing gonadotropins and GnRH antagonists.

"Embryoscopes," allow for embryo culture to be performed in an automated incubation system under time lapse photography. Manufacturers of these systems (and investigators who have used these systems) claim that the availability of 24-hour time-lapse photographic control improves embryo selection and, therefore, IVF (in vtro fertilization) pregnancy rates. They also claim that use of this system saves laboratory personnel time. This study will randomize approximately 120 patients (60 in each arm) to standard embryo culture or to culture in an Embryoscope. The primary endpoint will be a comparison of time spent by the laboratory personnel with each system. Secondary endpoints will be IVF outcomes.

Methods of infertility treatment may involve in vitro fertilization or IVF. Though effective, IVF is complex and expensive. Methods using no gonadotropin hormone stimulation of the ovaries are being compared to mild stimulation doses. The goal of the research is to determine which of these if more suitable as a low cost approach for varying individual patients.
