The Effect of Follicular Flushing on Oocyte Retrieval Rate & Embryo

Status Recruiting

Clinical Trial Summary

Researchers will investigate the effect of flushing according to follicle size on the success of obtaining oocytes from a single follicle. In addition, by comparing the morphological quality of embryos developed from oocytes obtained with and without flushing, the possible effects of flushing on developing embryo quality will be investigated. By evaluating only one follicle for each patient, it is planned to investigate the effectiveness of the flushing process according to individual follicle characteristics, with a study design that has not yet been included in the literature.

Clinical Trial Description

Prior to the oocyte pick up (OPU) procedure, the dimensions (height x width x depth) of the first accessible follicle in any ovary will be recorded in millimeters. In this regard, any follicle larger than 12 mm will be selected for the first aspiration. It is planned to evaluate the effectiveness of the washing process in follicles with different sizes by performing the first aspiration procedure regardless of the follicle size. After aspiration of all the follicle fluid with a double lumen needle (17 Gauge), the remaining fluid in the needle and line will be aspirated by giving 2 cc "flushing medium" to the follicle. In this way, all of the pure follicle fluid will be delivered to the in vitro fertilization (IVF) laboratory with the OPU tube for initial evaluation. After the evaluation, if no cumulus oocyte complex (COC) is observed in the first sample, the washing process will be started. In this regard, flushing and aspiration will be performed respectively by giving 2 cc "flushing medium" to the same follicle 3 times. A total of 6 cc flushing medium obtained after the flushing-aspiration process will be delivered to the IVF laboratory and the presence of COC in it will be investigated again under the microscope. Depending on the retrieval of oocyte by direct aspiration or flushing, each oocyte will be followed individually and its quality will be evaluated in case of embryo development from this oocyte. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
