What this trial studies

This study aims to evaluate the cumulative ongoing pregnancy rates between two different in vitro fertilization (IVF) protocols in women with low prognosis for assisted reproductive techniques (ART). Participants will be divided into two groups: one receiving a double ovarian stimulation protocol (DuoStim) and the other receiving a conventional antagonist protocol. The DuoStim group will undergo two phases of stimulation with oocyte retrieval and embryo cryopreservation, while the control group will follow a standard protocol with potential fresh embryo transfer. The goal is to determine which method yields better pregnancy outcomes.

Who should consider this trial

Good fit: Ideal candidates are women aged 40 or younger with specific ovarian reserve markers and a normal uterine shape.

Not a fit: Patients with conditions like endometriosis or Asherman's syndrome, or those who have undergone certain surgeries, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve pregnancy rates for women with low prognosis undergoing IVF.

How similar studies have performed: Other studies have shown promising results with similar double stimulation approaches, indicating potential for success.
