NCT03343938

Brief 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.

Study Arms (2)

Closed Station

EXPERIMENTAL

Embryo handling is performed inside a closed station with a controlled environment: 6% CO2 and 37 degrees.

Other: Embryo handling in a closed station

Open flow cabinet

NO INTERVENTION

Embryo handling is performed inside a conventional open flow cabinet without a controlled environment.

Interventions

Embryo handling is performed inside a closed station with a controlled environment: 6% CO2 and 37 degrees.
