About this study
Official title: The Effects of Miminal Stimulation Protocol on Clinical Outcomes of Advanced Maternal Aged Women With Preimplantation Genetic Screening
PGS has been the most effective method for embryo selection in IVF cycles. Euploidy rates decrease significantly with advancing maternal age (AMA). The dosage of gonadotropins also may be increased to recruit an adequate number of follicles in AMA women, minimal Stimulation Protocol (MSP) with the new combination of human menopausal gonadotrophin (hMG) and clomiphene citrate (CC) for controlled ovarian hyperstimulation is defined for poor ovarian response women. The aim of this study is to show minimal stimulation protocol affect euploidy and pregnancy rates in preimplatation genetic screening (PGS) cycles with single embryo transfer.

Questions about this trial
What is this clinical trial studying?
An observational study of Preimplantation Genetic Screening, run by Gokalp Oner at 2 sites in Turkey (Türkiye).
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 2 Feb 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
euploid rates (time frame: 3 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Feb 2022; AzTrials last refreshed its copy on 7 Nov 2026.
