Evaluation of a Closed Assisted Reproductive Technology (ART) Station Versus an Open Flow Cabinet
Spain78 participantsStarted 2017-10-31
Plain-language summary
There is not yet a standardized system of human embryonic culture in vitro. In addition, technical improvements continually appear. The investigators recently carried out a study in which it shows that the grouped embryo culture at low oxygen tension (5% O2) in a benchtop incubator shows better success rates than individual culture at atmospheric oxygen tension (20% O2) in a conventional incubator. For these reasons, the investigators have decided to continue this research line to evaluate the efficacy of a new ART station with a closed environment in comparison of an open flow cabinet. This new system keeps a controled environment maintaining a carbon dioxide (CO2) concentration of 6% and a temperature of 37 degrees. A prospective randomized study will be carried out in which the manipulation of the gametes and pre-embryos of the patients will be carried out in open laminar flow cabinets or in a closed station that maintain the CO2 and temperature conditions.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
